Boeing 777x First Flight

Boeing 777x Roll out

After two failed attempts, called off due to high winds, the latest addition to the 26-year-old Boeing 777 family has finally taken to the air. At 09:08 am, Saturday 25 January 2020, aircraft registration WH-001 started its takeoff run on runway 34 Left at Paine Field, Everett. With an 8 knot tailwind, broken clouds at 3,000 feet with 6 miles visibility, the largest twin-engine jet took a mere 30 seconds to become airborne. Applause and cheering from the crowd was drowned out by the worlds biggest jet engines, the GE Aviation GE9x.

Maiden flights of new airliners don’t happen very often, maybe once or twice a decade. Whilst the first flight of the Boeing 777x is a cause for excitement, Boeing must be feeling the pressure of getting this completely right in light of the 737 MAX situation. But enough of that.

The test flight lasted four hours out over the Pacific Northwest, a major milestone and the beginning of a very rigorous aircraft certification program. Before the aircraft can be delivered to airlines and begin carrying passengers, it has to go through a certification process. This is done with the F.A.A. (Federal Aviation Administration) and then no doubt with other agencies such as E.A.S.A. (European Union Aviation Safety Agency) before it can fly to, or overfly those regions. By current estimates, Boeing expects to be in a position to start delivering the first aircraft to customers in 2021. The first of those is expected to be Emirates. The order book for the 777x stands at 309 airframes with a list price of US $442M per aircraft. Of course, this is not necessarily what airlines will pay as they will have negotiated with Boeing for discounts around things like, number of aircraft ordered, or being the launch airline. Nevertheless, the sooner Boeing starts delivering, the sooner the income for this project will start.

The wingtip deployment can be clearly seen in this video as the Boenig 777x takes to the sky for the first time on a wet Seattle day.

So after 26 years of 777s (Tripple Sevens), what is so special about the 777x? Well, the original 777 was a step forward in its day, being computer designed it brought a lot of new ideas to the airliner design table. The 777x is carrying on that tradition by using technologies that have been tried and tested in the Boeing 787 Dreamliner. This includes using more composite materials in its construction, to make use of lighter stronger materials as well as materials which are far less susceptible to corrosion. Larger windows and an updated passenger cabin will be great news for passengers on this aircraft that Boeing maintains is the most efficient twin-engined airliner in the world.


The standout feature is the folding wingtip………


The stand out feature, however, is the folding wingtip. This feature, until now, was typical of fighter aircraft that were assigned to aircraft carriers. To save space when the aircraft was stored below decks, its wings would be folded upwards and thereby reducing the side to side space required for its storage. This is a concept that Boeing went with. To create the largest twin jet in the world, that is required to fly further than the previous version, was going to require a wing that gave more lift than the previous version. Winglets could have solved the problem to some extent, but it has been found that a longer tapered wing gives more optimal lift. The Boeing 787 and the Boeing 747 8 are testament to Boeing’s findings in this area.

So why folding wingtips? Well, let’s look at the Airbus A380. When it was introduced in the early 2000s, airports were required to make adjustments to gate areas to enable a much wider aircraft to be accommodated. They had to be “A380 Ready” before that airliner could land there. A huge upheaval and expense but it was seen as the new future and therefore was seen as an investment in that future. We now know of course that the days of the A380 are numbered, now that the giant twin airliners are coming of age. Boeing wanted to avoid the restrictiveness of requiring airports to upgrade to be able to handle an oversized wingspan. They wanted the 777x to be able to fly everywhere that the current generation of 777s can fly to. So was born the folding wingtip idea. The wingtips allow the 777x to change from a wingspan of 235 feet in the air down to 213 feet on the ground.

As the wingtips are a totally new technology in the passenger airliner space, the F.A.A. has come up with a set of 10 conditions that have to be satisfied before certification can take place. Boeing has stated that the non-deployment of the wingtips on takeoff can lead to catastrophic results. This is logical, as a fully laden aircraft, depends on the lift that those wingtips provide. If you suddenly have smaller wings than required, you are going by road with tragic results. The 10 conditions are designed to put fail-safes in place to


… you are going by road with tragic results……..


prevent the non-deployment of wingtips on takeoff as well as the failure of the wingtips to stay in place during flight. These conditions revolve around a comprehensive warning system to alert the crew to the fact they are attempting takeoff without the wingtips deployed. In addition, if that is ignored, there is the ability for the aircraft to prevent takeoff until wingtips are deployed. With every new technology comes a whole raft of things to consider and conditions to be tested for.

Like the Boeing 787 Dreamliner which started its early days as the 7E7, the 777x will no doubt be dropped in favour of the actual variant names of 777-8 and 777-9. Some basic statics on the two models are as follows:

777x VariantRangePassengers
Boeing 777-816,170km (8,730nm)384
Boeing 777-913,490km (7,285nm)426

Be sure to visit our Boeing 777x page for more details.

At 251 feet, the Boeing 777-9 will be the longest commercial aircraft in the world.

The road to this first test flight has not been a smooth one. From the time that the 777x was first rolled out of the hangar in March 2019, it was found that the new GE9x engine experienced excessive wear when run. In September when the wing stress testing was done, there was an explosive decompression event when a tear appeared in the fuselage. The manufacturing of the 777x was to be done in a fully automated assembly line by robots. Challenges in this area have forced Boeing to revert back to the traditional human-driven process.

The 777x is in the air at last. We certainly look forward to watching its progress toward certification.

Airbus Versus Boeing

For the first time since 2011, Airbus has outperformed Boeing.

As we all know, there are two main plane makers in the world today making the lions share of commercial passenger-carrying aircraft. Boeing and Airbus are more or less a duopoly in the skies and have been keenly fighting for market share for a number of years now. They’ve both had wins and setbacks from which they have managed to recover with lessons learned.

Now that 2019 is behind us, a year that many are quite glad to have in the rearview mirror, it might be interesting to see how it washed up for Boeing and Airbus.

It’s not hard to see which aircraft model was the most prolific in 2019. The Airbus A320 family of aircraft has been selling well for Airbus and in a year where the Boeing 737 MAX was not compromised by groundings, that aircraft should have been delivered in the same numbers.

Let’s not forget the turn around in the fate of the Super Jumbo Airbus A380. That aircraft was set to pick up the reins from the Queen of the Skies, the much loved Boeing 747, and take us into the new Millenium in style. What Airbus failed to recognise was that the advent of much better engine technology. This technology paved the way for the giant twin-engined jets to service those long overwater routes previously reserved for the four-engined airliners. This was bad news for Airbus as the sales of the A380 fell well short of the break-even point where the aircraft sales had covered the development and manufacturing costs. As if on a signal, different airlines cancelled their A380 orders or at least reduced them. The huge Emirates order will keep manufacturing going for a limited time until all orders of the type dry up.

It is not all bad news for Airbus, however. Where some of the A380 orders were cancelled, they were replaced by orders for the new A350 XWB. Even Emirates converted some of its A380 orders to A350 XWB orders. Obviously a cheaper option for airliners, and one that will continue to be developed into the future.

The smaller A320 family of aircraft have a higher production rate than the other models which is obvious from the graphic. These aircraft are produced in multiple locations to try and keep up with demand. Airbus is also ramping up the A220 production. The A220 was, of course, bought from Bombardier of Canada.

So, mixed results for Airbus. What of Boeing?

Boeing’s story is perhaps much more dramatic and has been very much in focus throughout 2019. As we know, the first event that gave a clue that all was not well with Boeing’s new 737 MAX happened in October 2018, when Lion Air flight 610 crashed into the sea shortly after takeoff from Jakarta, Indonesia. The investigation started to show there was a problem with the system that prevents the aircraft from going into a stall. The heightened likelihood of a stall was anticipated due to a larger engine on this model needing to be placed further in front of the main wing to allow it to be raised higher to achieve ground clearance.

The Boeing delivery figures for 2019 show clearly the gap left by the delivery of the smallest model, the 737. The MAX deliveries should have been around the 570 aircraft mark, not 121 as shown above. The larger aircraft such as the 787 and 777 have longer production times and so fewer are produced compared to the 737.

Tragically, this assessment was further proven correct when a second 737 MAX, Ethiopian Airlines flight 302, crashed in similar circumstances after departure from Addis Ababa in March 2019. Not even six months after Lion Air. The aviation world immediately responded by grounding the Boeing 737 MAX pending further investigation and rectification of any issues that were found. Boeing continued to produce the 737 MAX in the hope that the grounding would be lifted and deliveries could commence. As 2019 wore on it started becoming obvious that the MAX was not going to allowed back in the air anytime soon. The production was slowed from 52 to 42 aircraft per month, and on 14 March 2019, the first cancellation of a MAX order was received. It was from Garuda Indonesia for 49 aircraft. There have been a number of others and as we write in January 2020, Boeing has suspended production. To be honest, I believe they simply don’t have the space to park any more.

There are around 400 aircraft ready to be delivered. If and when the all-clear is given and dependant on what remedial work needs to be done on completed airframes to make them airworthy, Boeing will schedule the delivery of those aircraft while firing up the production lines again.

Here we see a summary of the 737 MAX order book from first orders back in 2011. Everything is progressing quite well, with a bit of lull in 2015 and 2016. First deliveries start rolling out the door in 2017 and 2018 shows a good solid performance. In 2019 we see the wheels fall off. We have negative orders due to cancellations by Garuda Indonesia and others and deliveries all but dry up as well.

There have obviously been some bad decisions taken down at Boeing. We can only hope that they can learn from their mistakes and turn this into a win for all. Faith needs to be restored with the airlines and of course their customers, the travelling public. There is a common saying used by many, “if it ain’t Boeing, I ain’t going”. They need to make people feel like that again to get back in the saddle.

So Boeing versus Airbus? Clearly it has been a win for Airbus in 2019. The European planemaker came late to the party, compared to Boeing and its long history, but there is no doubt that they are a worthy adversary in the big airliner market.

One giant leap.

Philippine Airlines Airbus A350-900

The story of aviation is certainly all about balance. How can you go further but still carry a profitable amount of payload? It is all about trade-offs. You can certainly fill an aircraft to the brim with payload, but you will have to leave fuel behind in order to be light enough to get off the ground. You can alternatively load up with fuel to go a long way, but you will then have to leave passengers and cargo behind, so once again you can become airborne.

Even with the newest technology those simple laws of physics still apply.

The Air New Zealand Boeing 787-9 will be the tool of choice when Air New Zealand opens its new long range route, Auckland to New York in 2020. The 787 is one of the new breed of giant twin jets using composite materials in their construction which offers greater strength at lower weights. This is the great enabler for ultra long range routes.

It seems, however, that every few decades improvements in technology allow us to take that next step. Whether it be the materials used in aircraft manufacture, the power and reliability of engines or the corrections to design theory. All evolved through lessons, often learned at a high cost. For instance, the move from canvas and wood to aluminium, the lessons learned about metal fatigue. The advent of the Jumbo jet, which brought travel to the common man. All, like our foray into supersonic travel, have been game changers. Some of these technologies have stayed and grown, others proved to be less popular. Not necessarily because they were bad in any way, but because they weren’t economical in most cases.

When all is said and done, airlines and airliner manufacturers are businesses with shareholders who expect to make a profit on their investment. Airlines find routes on which they can make a profit carrying passengers and/or cargo in a profitable way. Attracting customers depends on offering the service at a cost that is competitive and palatable to the market. The airline industry carries horrendously high operating costs. High fuel costs, aircraft that cost millions each as well as maintenance and other costs. So minimising cost, without impacting the level of service or safety is paramount.

The QANTAS Boeing 787-9 is currently being used on the ultra long range Perth to London route. QANTAS is embarking on what they call Project Sunrise which will see new non-stop routes opening from Australian cities to points all over the globe. On the 19th October 2019 a proving flight left New York to fly non-stop to Sydney, an exhausting 19 hours and 16 minutes.

Like any industry, it is important to use the right tools for the job. Airliners are those tools, and each of those models and variants has a very specific purpose and niche in the market. For example, smaller twin jets which can fly short to medium ranges to carry a small number of passengers more frequently. Larger transcontinental jets that carry many more passengers over greater distances.

So back to balance. The travelling public is becoming ever more mobile. Holiday makers travelling all over the globe to find those, as yet, unspoiled destinations. Business travellers, similarly, need to get to all sorts of far flung destinations to close that deal. To the business traveller, time is money, so get me there quickly. To the leisure traveller, too many hours in that economy class seat are soul destroying, among other things.

This is where technology is currently being focused. Being able to fly further from more origins to more destinations. What does that mean?

Let’s look at the iconic Boeing 747. It was designed to operate out of big city airports. It is big and needs a big runway to take-off and land on. So, the system, known as hub and spoke was used. For example, you take the Boeing 747 from London Heathrow to New York JFK, then change to a smaller commuter airliner to go on to a secondary city. That makes for a long journey, not very convenient. There were several factors that led to things being done this way. One is engine reliability. Aircraft and their engines need to be certified (ETOPS) to fly long over water routes. This is particularly true of twin jets.

For many years, aircraft like the 4 engine Boeing 747, Boeing 707, Douglas DC8, Airbus A340, as well as the 3 engine Douglas DC10 and Lockheed L1011 were the mainstays of trans-oceanic travel. Airbus perhaps came a little late to this game with the Airbus A380. Certainly, a marvel of aviation technology, the A380 has not met its sales potential for Airbus. Existing customer airlines have shortened their orders as they have seen that the game has changed.

The age of the giant twin jet is upon us.

Engine technology has enabled the production of engines with a far lower failure rate then in the past. Through testing and the resultant certification, large twin-engine jets like the Boeing 787, Boeing 777 and Airbus A350 are able to fly further from the nearest available airfield then past twins. This is what makes trans-oceanic travel possible.

Delta flies one of the worlds longest non-stop routes from Johannesburg to Atlanta which takes around 16 and a half hours using the trusty Boeing 777-200LR. Shortly we should being seeing the newer Boeing 777X, which will come out in in a 777-8 and 777-9 variant.

The economics are obvious. Twin jets require less spares to be kept in store, less maintenance. Not being as big as their Jumbo and Super Jumbo predecessors, they can fly into smaller airfields, doing away with the need to transfer through busy main hubs.

So, what about the further part?

The new twins, particularly the Boeing 787 and Airbus A350, use a high percentage of composite materials in their construction. Carbon fibre and plastics provide strength but at a lower weight than aluminium. This delivers benefits in having a lighter aircraft with the same if not higher strength. Keeping the base weight down enables a higher payload which is great news for the airlines operating them.

Back to the balance. Being able to carry a higher payload means we can carry more fuel without leaving as many passengers behind for those long-haul routes. This is important for more remote parts of the world, like Australia and New Zealand. QANTAS the Australian national carrier, for its part, is focused on Project Sunrise. The aim is to fly non-stop from Australian capital cities to major destinations around the world, like London and New York. They have already been operating from Perth to London non-stop for a few months now, a flying time of 17 hours 45 minutes. On 19 October 2019, QANTAS took delivery a Boeing 787-9 with which they performed a publicity flight under the number QF7879 from New York to Sydney, non-stop. The flight took 19 hours 16 minutes and carried 50 odd passengers and crew. Data was taken of how each passenger dealt with the nearly 20-hour flight. It will be interesting to see their findings when they are publicised as this may help us to understand and mitigate the effects of super long-haul flight.

Air New Zealand announced that they would commence flying non-stop Auckland to New York, a flying time of between 17 and 18 hours. The options for travellers in a hurry to get to their destinations are certainly about to explode. Whilst these services will no doubt be aimed at the upper end of the market for now, I’m sure they are looking at ways to make sitting in economy for those extended flying times possible.

How do you feel about super long-haul flight? Would you be keen to take a nearly 20 hour flight, and what class of travel would you travel in? We would love to hear how you travellers feel about that?

Airbus announces the end of A380 production.

Emirates Airbus A380-861

European aviation powerhouse, Airbus, announced, not unexpectedly, that they would cease production of the A380 Super Jumbo.

The huge double-decker A380 was set to revolutionise air travel in the new millennium and give stiff competition to the Boeing 747 Jumbo. Able to carry over 500 passengers across long distances, the A380 looked like a sure bet in that niche market. Launched in 2008 by Singapore Airlines, the future looked hopeful with orders from many of the worlds prestigious airlines. Notably, Middle Eastern airline giant, Emirates, ordered a whopping 162 airframes. Airbus expected to sell around 1,200 A380s in order to recoup development cost, and of course, turn a profit. The actuality is that they have not even achieved a quarter of this target. As at the 31st of January 2019, 234 A380s have been delivered with 232 in active service. Of these 106 are with Emirates.

Where did Airbus go wrong? Like anything in the commercial world, the economics no longer stack up. The high price of the aircraft, coupled with the extensive upgrades required at airfields, before they can accommodate the Super Jumbo, led to very high overheads. Aviation, like most industries with an accent on technology, are ever changing. It can be very difficult to predict future trends, and Airbus is not alone in this. Boeing also got burned by this trend with their 747-8i. Designed as the descendant of the much loved 747, it met with a very lukewarm reception and has since ceased production. Boeing at least could fall back on the original failsafe of the 747, by creating a freighter version of the 747-8. This has done slightly better. The bubble on the original 747 was to enable a freighter version to be loaded through an opening nose door. They didn’t have faith that the passenger version would sell, so took an “each way bet”.

The focus seems to be now moving toward the long-range twin-jets. Both Boeing and Airbus have a wide range of offerings in this space, which offer airlines a wide choice across their whole network. The economics of filling one very large aircraft to the point of profitability can very challenging. With slightly smaller aircraft, routes can be flown more frequently and economically. Today’s giant twins like the Airbus A350-11 and the Boeing 777-9, are coming online and are enabling airlines to offer non-stop services between cities where it has not been possible in the past. Airlines, like QANTAS, are rethinking their strategy and proposing services that to date have not been possible.

An Airbus A380 destined for Emirates takes shape in the Toulouse factory. When production ends for the Super Jumbo in 2021, there are an estimated 3,500 jobs that will be at risk.
An Airbus A380 destined for Emirates takes shape in the Toulouse factory. When production ends for the Super Jumbo in 2021, there are an estimated 3,500 jobs that will be at risk.

Only a few days ago QANTAS announced that they would no longer require the remaining 8 A380s in the order book. Virgin Atlantic also withdrew their order of 6, as they no longer wish to take up the A380. The final crunch came when Emirates announced it would reduce its order of 162 by about 20 aircraft. Once the balance of the Emirates and A.N.A. orders are fulfilled, there is no further backlog. Airbus anticipate closing production in 2021, which could impact up to 3,500 jobs. Not only will this affect Airbus, but also the many suppliers who create components for the giant aircraft.

It seems the A380 came along just a little late in the day. The focus of aviation has changed once again and it seems the day of the giant 4 engined Jumbo is over.

QANTAS Airbus A380 Orders Capped at 12.

QANTAS A380 VH-OQA taking off

Back in 2006, QANTAS was one of the first airlines to place an order for the Airbus A380 Super Jumbo. 20 of the type were ordered which certainly lifted the QANTAS image as an industry leader. On 21 September 2008, the first A380, registration VH-OQA named for the much loved and respected aviatrix Nancy-Bird Walton landed in Sydney. Over the next 3 and a half years Airbus delivered 11 more airframes with the last of the 12 arriving in December 2011. VH-OQL, named Phyllis Arnott after the first woman in Australia to take a commercial pilots licence, is now officially the one that concluded the order.

For the last 8 years, QANTAS has had 8 A380s outstanding in their order book with Airbus. Sources at QANTAS indicate that those remaining 8 aircraft have not featured in its future network plans for some time. This week it was announced that the remaining 8 would no longer be required and in discussions with Airbus formally cancelled that remaining order. This is no doubt bad news for Airbus as this cancellation is a significant contributor to the $US4 billion in lost contracts. Airbus is putting a brave face on it, one source quoted as saying, “one month does not make a year”. Let’s hope they’re right.

When we look at the order book for the A380 as at the end of January 2019, we see there are 313 orders with 234 airframes delivered of which 232 are currently in active service. The QANTAS order for 20 aircraft was the third largest behind Singapore Airlines and Emirates. The Emirates order itself is what is keeping the A380 factories open. Of the 162 ordered by the giant airline, 109 have been delivered. We also note that Virgin Atlantic who had 6 on order have now dropped off the order list.

Whilst Airbus might see the Emirates order as being a lifeline for the A380. There is talk that Emirates may also be rethinking their strategy and perhaps looking at the A350 as a viable alternative. As we wrote back in 2015 about the 747-8, is the day of the 4 engined Jumbo sized aircraft at an end? We can only speculate, and of course, Airbus is remaining tight-lipped, about whether we will soon see a closure of the Airbus A380 production line?

QANTAS say they are committed to the A380s in their fleet and around mid-year this year, they will embark on a revamping and upgrade of the interiors of their A380 fleet. So there certainly is committment to the type in the future.

Project Sunrise

Described as the last frontier of aviation by CEO of QANTAS, Alan Joyce, is the non-stop flight to anywhere in the world. The advent of the giant twin-engined airliners is bringing this dream into reality. QANTAS recently took delivery of its Boeing 787-9 Dreamliners which have been deployed on the Perth to London non-stop flight route. This will become available for East Coast Australian cities soon as well. Mr Joyce indicated that the aircraft are stripped back and are targeted at the higher end business market. Cargo may even be sacrificed in favour of sleeping berths for the extremely long flights.

The QANTAS Boeing 787_9 Dreamliner is pivotal in Project Sunrise, bringing more of the world into the non-stop flight umbrella.
The QANTAS Boeing 787_9 Dreamliner is pivotal in Project Sunrise, bringing more of the world into the non-stop flight umbrella.

Perhaps we are at that tipping point where those longer flights are becoming economically feasible. If we go back a few years, the Airbus A340 was given as a solution to those ultra long flights that other airliners could not compete with. Singapore Airlines pioneered some of those long routes, but eventually the economics didn’t stack up. The long-range A340 became known as a flying tanker with a few passengers allowed along for the ride.

QANTAS also introduced an extremely long route from Sydney to Dallas, Texas using their Boeing 747 400ER. It was quite a stretch, and on several occasions on the Dallas to Sydney leg which is against the jet stream, the aircraft had to stop over in Noumea due to low fuel. This route is now operated by the Airbus A380.

Orignally Mr Joyce of QANTAS was adamant that the Project Sunrise aircraft would carry in excess of 300 passengers. This has been revised back now, and may well follow the lead of Singpoare Airlines on their Singapore to New York route using an Airbus 900ULR (Ultra Long Range). This non-stop flight of 18 hours is available to 67 Business Class travellers along with 94 Premium Economy Class travellers. Certainly a high end portion of the market. For high flying business travellers, this is the quickest way to get there, so may be money well spent.

Perhaps we’re not all as keen as those business travellers to shave a few hours off our trip and pay those premium prices. But there are new aircraft being developed and improved all the time. The likely candidates are the Boeing 777X and the Airbus A350 1000. We mustn’t quite forget about supersonic travel either. Concorde may not a have flown for a decade and half, but that doesn’t mean the concept is dead.

Is Boeing buying its way into the supersonic market?

Aerion AS2 Supersonic business jet

No sooner had we posted our article on the prospects of future supersonic jets gracing our skies again, and here comes an announcement from Boeing and Aerion of Reno, Nevada. The giant plane maker, Boeing, on Tuesday 05 February 2018 made a significant investment with the experts in supersonic technology, Aerion. The financials involved have not been disclosed, but suffice to say it will no doubt help out with the US$120 million development costs for the Aerion AS2. It must have been a good deal as Boeing shares touched a record high of US$407.48 after opening above US$400 for the first time ever.

The reasoning behind the investment can best be summed up in a statement by Steve Nordlund, vice president and general manager of Boeing NeXt. He said, “through this partnership that combines Aerion’s supersonic expertise with Boeing’s global industrial scale and commercial aviation experience, we have the right team to build the future of sustainable supersonic flight.”

As a side note, Aerion and Lockheed Martin were in a Technical Viability partnership from 2017 which lapsed on 01 February 2019 to develop the AS2. Neither party expressed willingness to further this partnership. It almost seems that Boeing was waiting in the wings.

So what is the AS2? What is Boeing buying into?

The Aerion AS2 is a business jet designed to cut travel times significantly. Here are some specs.

The obvious question is, how will the AS2 suceed where Concorde failed? The restrictions for supersonic flight over land are still very much in place. Because of the sonic boom created by shock waves as the aircraft crosses the sound barrier, these aircraft are not permitted to over fly land for environmental and social reasons. So what has changed?

A model of the Aerion AS2 Supersonic Business Jet (SBJ).Note the squareness of the wings, much more like a modern fighter than the classic Concorde delta type wing.

There is certainly pressure in the United States on governing bodies to relax the rules around supersonic flight over land. This may or may not be successful. However, in Europe there seems to be no appetite for relaxing these rules, and Europe of course is a huge destination for any business related travel. Relaxing of legislation, therefore, cannot be a condition that supersonic plane makers should count on.

The solution has to be in the technology. To minimise the sound shock wave as much as possible, the AS2 is designed with a very long tapered fuselage. This helps to control the length of the wave, thereby lessening the resultant boom. Aerion have developed BOOMLESS CRUISE™, which they say will enable the AS2 to cruise at speeds approaching Mach 1.2 without the sonic boom. This is dependant on temperature and wind. Once the AS2 gains certification Aerion intend to work with authorities in order to gain approval for this cruise capability.

There is a third feature in the AS2, in that it can fly just as efficiently at Mach .95 as it can at super sonic speeds. Mach .95 is still significantly faster than current passenger airliners, so with this flexibily, the AS2 certainly has the ability to suceed where Concorde failed. Whilst not as fast as Concorde, the AS2 has the capability of flying anywhere in the world without noise related restrictions. She will still have the ability to shave 3 hours off a trans Atlantic flight as compared to present day airliners, which is significant.

The AS2 will come with various cabin configuration options, from standard airliner seating to dual cabins with lounge chairs in one and a meeting table in the other.

On the outside, the AS2 is very sleek as mentioned above, with a long tapered fuselage. Aerion have done away with the delta wing of Concorde and gone for a more square wing, similar to modern fighter jets. The wing is very square with sharp angles and very thin. Originally Aerion were leaning toward two 19,000 lb thrust Pratt and Whitney engines, but changed to the present configuration of three 15,000 lb thrust GE Aviation engines. The tri-jet configuration they found offered better take-off performance.

It will be great to see supersonic travel coming back into focus. The renewed interest will no doubt lead to technological advances and enable supersonic jets to become the new normal. That, surely, will make air travel much more attractive.

Is this the return of the Supersonic Jet?

Aerion Supersonic Business Jet

A new Supersonic Jet is just around the corner.

Not since 24 October 2003, when the futuristic Concorde made her last flight, has supersonic air travel been available to the masses. Well, we use the term masses loosely. Concorde was an extremely expensive machine to run and those who flew her paid top dollar for the privilege. In addition to the high running cost, she was also limited to flying over water at supersonic speeds due to the sonic boom created by flying above the speed of sound. For environmental reasons, most countries banned the supersonic jets flying over their territory because of the sonic boom. This naturally limited the appeal of this aircraft due to the limitation of the routes it could be usefully flown over.

It is amazing to think that this technology was available until nearly two decades ago. High flying businessmen in London, for example, could go to New York, do their business, and be back home for dinner. Surely that demand is still there.

So what are the challenges that a Supersonic plane design has to overcome? The main ones are, cost to operate, sonic boom noise, landing/take-off noise and emissions.

We can agree that technology has certainly made vast improvements in the time since Concorde flew. Engine technology has enabled more power to be delivered by quieter engines. Composite materials have given higher strength to airframes at lower weights as well as lower manufacturing costs. One thing remains, however, the sonic boom. This limiting factor is still a roadblock.

There has been, over the last couple of years, increasing pressure in the U.S. for environmental standards around supersonic transport aircraft to be relaxed. There are three start-up companies that have already invested considerable money and resources into the development of their own version of a supersonic transport aircraft. These are: Boom Technologies with their Mach 2.2 capable airliner, Spike with their Mach 1.6 capable S-512 Quiet Supersonic Business Jet and Aerion with their Mach 1.4 capable As2 Business Jet. These are all slated to be ready for service between 2023 and 2025. Even the Russians are dipping their toe back in the supersonic pond, with the United Aviation Corp (UAC) aiming to start on their own offering in 2022. You may recall Russia had a Concorde look alike, the Tupolev TU-144. Dubbed, the Koncordski. This aircraft never met with any success, being used on domestic routes only, until it suffered a final setback, breaking up in flight over the Paris Air Show.


The hypersonic airliner will travel at mach 5……..


Meanwhile, the household name manufacturers are still hard on the case. Boeing has had various designs over the years to enable it to enter the Super Sonic Transport (SST) space. None have got much further than the drawing board. They are, however, working on a new concept that they hope will reinvent our expectations of fast flight. The hypersonic airliner will travel at Mach 5, which is about 3800 mph (6110 km/h) or five times the speed of sound. This is still around twenty to thirty years away and no doubt will depend on technology that to date has yet to be made available. Lockheed Martin also has an offering in the works. In 2018 Lockheed Martin was selected to design a Low Boom Flight Demonstrator(LBFD). Their X-59 QueSST (Quiet SST) will fly at 55,000 feet at a speed around 940 mph / 1,513 kph / 817 knots. The aim is to reduce the sonic boom from a boom to a light thump, a bit like car door closing.

In July 2018, the International Council on Clean Transportation (ICCT), under the lead authorship of Dan Rutherford produced a report called, “Environmental performance of emerging supersonic transport aircraft”. The report was drawn from studies and simulations carried out at Stanford University and was in response to mounting pressure on the Trump Administration to relax rules governing overland supersonic flight in the U.S.A..

The report looked back at Concorde and compared it with conventional airliners of the day, say the Boeing 747. It was obvious that in every aspect, the Concorde was less environmentally friendly. The supersonic plane was less fuel efficient, noisier at airfields, emitted higher levels of nitric oxide in the take-off and landing phases, higher levels of carbon dioxide in cruise, not to mention the sonic boom. They then looked at the situation today. As we’ve mentioned already, technology has moved forward in many aspects of aircraft manufacturing. Does this work for the supersonic jet manufacturer? Yes, of course new things are possible now that were not in the 1960s when Concorde was developed. However, the bar has been lifted as far as eco standards around commercial aircraft are concerned.

The report found that that the gap between conventional airliners and the new generation of supersonic planes was much the same as those in the time of Concorde. So, let’s say the U.S. relaxes its rules around supersonic jet travel. Will this be enough of a market for plane makers to make a profit out of? The U.S. relaxing their rules doesn’t mean other countries will follow. In fact some European countries have made it clear that they will not entertain the idea of supersonic flights over their territories. Even flying to those countries, with the last overland portion done at subsonic speeds may not work, as there are still airport noise and emission standards to overcome. So, needless to say, a complex issue.


…. around 5,000 supersonic flights a day…..


For an aircraft manufacturer, the idea is to develop an aircraft for which you have calculated there is a market which will enable you to sell enough to recoup your cost, as well as making a profit. Some of the supersonic jet maker start ups are estimating that they will be producing up to 2,000 airframes. These aircraft will serve up to 500 cities by 2035. Imagine, around 5,000 supersonic flights a day. Over a 16 hour flying day, there could be a sonic boom every 15 minutes.

Needless to say, there are exciting times ahead. We would love to see the return of supersonic flight, but in a way that is sustainable to the environment. There is no doubt that solutions to the roadblocks will be found.

How can I maximise my carry on luggage?

Wheelie bags are popular to use as carry on luggage.

How can I maximise my carry on luggage?

I remember when carry on luggage was simply a bag of goodies you took into the aircraft cabin with you to keep yourself amused for a long flight. I used to relish handing over my suitcase(s) to the check-in person and walking away almost empty-handed. For longer trips away I still enjoy that.

There is now, however, a change to the way we think about how we take our stuff with us.

Checked in luggage is becoming less common as travellers try to make use of the free carry on option.
Checked in luggage is becoming less common as travellers try to make use of the free carry on option.

The changes have several contributing factors. Firstly, we seem to spend a lot of time at airports

these days queuing for stuff. Security checks for one thing. So people are focusing more and more on how they can get through the process and be on their way more quickly. Having only a cabin bag is ideal for this as you can bypass the baggage carousels and be on your way very quickly. Secondly, the advent of unbundling airfares has led to the option, on many airlines, of paying for what you want and not what you don’t want.

…….. You can bypass the baggage carousels and be on your way……

One of the things that you often have to pay for is checked in baggage. Many travellers see this as an opportunity to be able to reduce their airfare cost. We can forego paying for meals and more desirable seats. In the same way, we can reduce the cost by carrying our bag into the cabin, not to mention the previous point of not having to wait for that last bag off the carousel at your destination.

Now, believe it or not, the airlines have also noticed this trend. When the baggage trolleys start going out to the aircraft half empty and everyone is turning up to the boarding gate with wheelie bags, something is changing. Like any business, airlines hate people getting away with something for nothing. Responding to the trend of travellers choosing to take advantage of the free carry on luggage allowance, they have started to clamp down on this allowance. In times gone by, the boarding gate people would just let you go through with your bags, provided they looked like they might fit in the overhead locker or you didn’t look like you were carrying bags of cement.

Yes, size does matter……..

Not so now. Nowadays you can expect to have your bag scrutinised, weighed and even put into that funny frame thing to check it is small enough to fit into the overhead locker or under the

seat in front of you. Yes, size does matter, but then so does weight. I wish we could say that there is a uniform rule about these weights and dimensions, but unfortunately, every airline has it’s own idea of what this should be. Checking the airline website is really the only sure fire way to know what that allowance is. This is easy if you are travelling on one airline all the way. What if, for example, you are travelling from Singapore to Copenhagen via London. You might get a nice generous allowance from Singapore to London and then on your low-cost carrier flight on to Copenhagen you get virtually nothing. This means of course that the meager allowance for the second sector becomes the governing factor for the whole trip. Unless of course, you anticipate consuming the difference on your first flight or posting the difference to Copenhagen from London.

What do we need to think about if we are choosing to go down the cabin luggage only path? First off we need to be aware of all the things that are prohibited in the aircraft cabin. It would be a depressing start to the trip if many of our items were thrown out at the security check. So first off, make sure you check with your airline website to see what the prohibited items are. These are fairly standard these days, but things do change and it pays to know, as ignorance is no defence.  Right?

Smart packing is your friend. Think about what you actually need. Many of us over-pack, just in case, you know. With clothes try and make sure you wear your heavier clothes and that the lighter weight ones are in your cabin luggage compliant bag. For example boots, jeans, jackets, belts and coats can be worn or at least thrown over your arm, well maybe not the belts, jeans or boots. I’m not saying you do a Joey Tribbiani from Friends, but you get the picture. When you do pack your clothes, roll them instead of folding them. This ensures you can use all the space most effectively and also your clothes will be less wrinkled and ready to wear when you get to your destination.

Now, toiletries. Of course, we know about the restriction on liquids in the aircraft cabin. The rule of thumb is no more than 100ml, but, yes I’m going to say it again, please make sure you check with your airline webpage to be completely sure. This means you need to pour the contents of your favourite shampoo, conditioner, etc into smaller 100ml plastic bottles. These can be purchased very cheaply and you can use them each time you travel. Make sure of course they close firmly as even in the aircraft cabin the difference in air pressure with ground level is significant enough to encourage liquids to try and leave the security of their container to go exploring in your clothes. Believe me, they prefer your clothes as it is very hard to get rid of things like shampoo and skin cream out of them.

…..contain any random liquids or creams that make good their escape.

That brings me to the next point. Your toiletries bag. Put that away in the cupboard again as it won’t help you with you space saving or weight saving. You are much better off with a plastic zip

lock bag. The zip lock bag can be made to lie very flat among your clothes which is a great space saving technique. In addition, the plastic is more liquid proof than some toiletrie bags and can contain any random liquids or creams that make good their escape. When you do seal your zip lock bag, ensure you remove all possible air inside the bag as this will expand like a balloon as the cabin pressure reduces on climb out.

Metal items are another area that care needs to be taken. Even though we know not to bring knives, scissors etc.. Care also needs to be taken to not include items that look like knives and scissors. For example, you can get tweezers that may have scissor type finger holes. These are to be avoided in favour of the tong style variety. What you have to think of is how it looks to the x-ray machine operator. You may well get them through security eventually but who needs the grief of having to unpack your bag to show them the offending item. It may just put them in a mood to examine other stuff or confiscate the item anyway.

So what about our ever hungry electronic equipment?

Cabin bag stowage in the overhead locker can work for everyone if you show your case on its side with the bottom of the case against the back wall.
Cabin bag stowage in the overhead locker can work for everyone if you stow your case on its side with the bottom of the case against the back wall.

So what about our ever hungry electronic equipment? No one needs the angst of thinking their gadgetry is going to run out of juice, but those plugs can weigh a bit. Consider perhaps taking only the cable part of the charger with the USB plug at the end. Most aircraft have the USB plug point for your flight, so that is covered. At your destination many hotels have USB points now, but if not smart TVs have them. If you do need to take one and your bag weight is getting up there, then maybe a jacket pocket could be the answer. This could apply to any smaller but weighty items like camera lenses and the like.

So we’ve seen how it is possible to save on your next flights. Free cabin luggage is a boon for those who can squeeze their trip into a smaller bag. Let’s make the most of this while we can as you can be sure that airlines will come round to finding a way to charge for something we are currently getting for free.

Please share any ideas you might have about maximising cabin luggage, we would love to hear them.

How to find airfare deals

How to find airfare deals.

So you’re planning that special trip away, but how do you get the biggest bang for your buck when buying those flight tickets for the plane trip portion of the journey?  Like anything worth doing, finding the best airline flight deals takes a bit of planning.

Timing of your plane trip.

Airliner on approach.
If your timing is flexible then use this to your advantage.

If you have some flexibility around the timings of your trip, you can use that to your advantage. Travelling in off-peak times means you won’t be paying premium prices. Airlines, like any other business, use the supply and demand principal to maximise their return. For example, during the week you will find that early morning and late afternoon flights rarely have cheap fares available because these flights are frequented by business travellers. The airlines know that these flights will be well filled, so there is no need to offer cheaper fares. So avoid these times if at all possible. Time of the day is therefore important.

To find a cheap flight, other time factors are also just as important to consider. Times of the week also make a difference. For example, business travellers going to more distant destinations tend to go for the week. This means that Monday mornings and Friday afternoon/evenings are also peak times and unlikely times to find airfare deals. On top of that, you have weekenders departing on Friday evenings and returning on Sunday evenings.

So much to consider.

Other timings to consider in the search for your cheap flight ticket.

Ok, so we’ve considered the times above that are unlikely to provide us with good airline flight deals. That is, of course, assuming we have also ensured we’re not travelling on a public holiday or around a sports or other event. In that case, all bets are off and prices go through the roof.

If you are travelling internationally then that adds a whole extra dimension to the exercise. Not only should you consider peak times in your origin country, but also those of your destination country and countries you might be passing through along the way. For example, I once travelled to London with a stop in Hong Kong along the way. I thought I had covered all my bases, but still, I couldn’t find flight prices that I felt were a good deal. The reason I found out was that it was the end of the summer school holidays in the UK and many children attending boarding school in the UK were returning to London. Lesson learned.

Check Airline Prices.

Having done our due diligence and decided on some dates that we feel are optimum for avoiding any peak periods. What next?

Looking for a cheap fare doesn’t mean you have to travel on old aircraft. New state of the art airliners like the Boeing 787 Dreamliner, Airbus A350 or A380 are designed to fly more economically and therefore give the airlines the ability to be more competitive.

Next, we need to find out what options are out there. Which airlines fly to our chosen destination? Also, another factor to consider and decide upon is, what class of travel we want to travel in. Talking about cheap fares, we may conjure up pictures of backpackers travelling on ancient aircraft stopping in 25 mountain villages along the way, just to save a few coins. Not necessarily so, unless of course, you want it to be. A cheap flight ticket can be any ticket that is a good deal for the service you receive. So whether you want to travel first, business or economy class, the principle is the same. Airlines put out deals on flights that they are having trouble selling. So decide at the outset what level of comfort your budget will allow for.

The class decided, we start our search. To start, go to neutral online travel agency sites that sell all airlines equally. Well, that is perhaps a little naive. Even online travel agencies have preferred airlines they sell due to higher levels of return for them. With this in mind, still perform some searches on those sites. This will give you a feel for which airlines are relevant for the route you wish to fly. Also, another handy tool is Google Skyscanner. You can perform searches as you can with online travel agents and find out which airlines fly and which fares are currently on offer. You can even set up alerts so that when prices change from your preferred options you will receive an email. This can be handy in case you forget the check back and a special is released.

Once you have ascertained which airlines are relevant to your requirements, visit their websites as well. I would recommend subscribing to alerts from them so that you get to hear about specials as they start or even before they start. A special fare doesn’t mean that all seats on that airline for that route will be sold at that price. Airlines work overtime to control yield and special fares will be allocated on flights depending on their popularity. On a peak time flight, even during the special fare period you will, in all likelihood, find no special fares. On less popular travel times, however, you will find those fares.  Airlines review these constantly and will adjust the number of special fare seats up or down depending on how sales are going. Special fares work much the same as loss leaders work in other industries. For example, in your local supermarket, you see those items at the end of the aisle facing the front door being sold very visibly at knock-down prices. These items can be sold at a loss because they get people in the door and put them in a buying mood which they know will in most cases lead to sales of other items sold at the normal price.

Airlines will do the same thing. Release a very small percentage of seats at a very low price to

If airlines did not fill their flights with cheaper fares then it would cause them to lose money as those flights still have to fly, empty or not.

get people onto their website. Once there they have this idea that the prices are nice and low today, they will look and see that the special deal fares are available on flights that they don’t really like the timings of, so they look at the next fare up to see if there are better options. In their minds they have already spent the amount of the special fare and they then see the difference between that and the not so special fare as the actual amount they are spending, which doesn’t seem so bad. Boom, the airline’s plan worked.

The message here is don’t lose sight of the bottom line.  If you find the special fare is not giving you what you need, back out and keep the research going, unless you are happy with the new option you have found.

Where should I actually buy the fare?

This is a good question and no one answer is right. The travel industry can vary somewhat from country to country, but one thing you can count on is that it isn’t straight forward. We talked about online travel agency websites. These are great for seeing which airlines are the ones you should be shortlisting as logical options for the route you will be travelling. Should you buy from these websites?  Well, that depends. The travel agency needs to make money obviously, so how do they do it.  Once again there is no straight forward answer to that.  In years gone by there was a standard procedure where a travel agency sold an airline seat and the airline paid them a commission of X per cent. Easy. Now, not so much. Very few airlines are now paying commission to travel agents. Let’s take a look back a few decades.

Back in the early days of travel, we didn’t have the technology we have today. In fact, it was the airline industry that was at forefront of driving the development of computer networking. But that is an aside. In those early days, travellers had to come into an airline office to pay for their tickets. Of course it was not possible for an airline to have offices in every town village or city, so enter the travel agent who literally acted as an agent for that airline and collected money on behalf of that airline, and of course others. Now enter the online age and all of a sudden airlines can actually be everywhere. As a result, they, for the most part, have decided to stop paying those commissions that travel agents relied upon for so long.

Travel agents and airlines used to have a good working relationship as airlines couldn’t logically have an office in every town.

So who pays now? This is also not a single answer question. In most cases you, the traveller, will pay a fee. So for the travel agency website you may well see some cheap fares but beware of the fees at the end, they may well undo the advantage you gained by finding a cheap fare on their site. However, don’t discount using these agency sites. Some travel agencies have such high brand recognition that they can command respect from the airlines due to the high turnover of travel sold on their site. In a case like this, an airline might offer the travel agency net fares which are far below even what the airline is selling them for. The travel agency will mark them up and the mark-up will be their profit.  They will mark them up to such a level as to ensure a good return but remain at a very competitive level.

So, in short, there is no recommendation as to which is better, the travel agency site or the airline site. It really is a case of who comes up best on the day. It is definitely worth doing your due diligence.

So we’ve looked timings and the source of the special fares. One more thing that is worth considering is the routing of your flight. You will these days have seen that modern airliners are breaking all sorts of records in long-haul non-stop flights such as Perth to London, Singapore to New York, Auckland to Dubai. The list goes on. Yes, these can save a lot of time and if time is a concern then these are a great solution.  If however, time is not so important and you don’t mind spending a few extra hours getting there, then check out services that do have stop-overs along the way.  For example, I used to travel to Europe from Sydney fairly regularly and I would choose to fly a carrier via Dubai. I had the option of the Sydney direct to Dubai, changeover and then on to London. Instead, I chose the option that touched down in Bangkok for an hour or so on its way to Dubai. It took a couple of extra hours but I enjoyed a cheaper fare, as it was less popular with those in a mad rush, and I had the opportunity to stretch my legs and get some real air along the way.  It comes down to personal preference but there are opportunities to save.

I hope this has been some help. By all means, we would be happy to hear your ideas on how to save on your travel spend.

Flight mode, why do we need to use this when we fly?

Flight or Airplane Mode

Air travel is something that a great many of us get to do reasonably frequently.  For some, it is too often, for others it is not often enough. Whichever it is, we are all familiar with the various announcements that are made on-board, particularly this one…

“At this time, make sure your seat backs and tray tables are in their full upright position and that your seat belt is correctly fastened. Also, your portable electronic devices must be set to ‘airplane’ mode until an announcement is made upon arrival. Thank you.”

Game controller flying your plane.
Your new pilot, the kid with the game controller.

Most of us dutifully obey the instruction and reach for our device(s) switching them either off, or to the particular phone makers version of Flight or Airplane mode. It wasn’t so many years ago that the devices had to be turned off completely from the moment you arrived at your seat until such time as the aircraft reached a certain altitude. We were led to believe that our mobile devices would interfere with the aircraft’s systems and it was very much in our own interests to keep those devices switched off. I always used to have visions of some 10-year-old kid in row 36 who managed to get his game controller linked to the flight controls and then take us through some barrel rolls and loop de loops.

Things have changed a little now. Your mobile phone can be left on, with most airlines, for the whole flight and the only concession you have to make is to ensure it is in Flight Mode for the duration of the trip. This is of course only for devices weighing under 1Kg. Not because they emit a stronger signal or anything, but because they can become seriously dangerous projectiles in the event of the aircraft performing extreme manoeuvres.  So you will be asked to stow those during take off and landing.

…because they can become seriously dangerous projectiles in the event of….

Ok, so back to the Flight Mode question. Why do we still need to use flight mode during the course of the flight? Various sources indicate that the effect of a mobile phone or cell phone on an aircraft’s flight instruments is fairly negligible. Aircraft instrumentation is state of the art as you would expect from a unit costing tens if not hundreds of millions. There are so many systems with many kilometres of wiring throughout the aircraft that need protecting from each other, never mind your mobile device. These systems are fully shielded so that attenuation or interference from outside sources cannot corrupt signals sent around the systems.

So does that mean we can go ahead and just ignore the request for flight mode from the crew then?  Not quite. There is still a relatively old technology used by the flight crew. The radio. No, not the one tuned to the football, but the one used in the all-important communications with air traffic control. The giving and receiving of instructions is still done using the good old radio waves.  Mobile devices depend on microwave towers or other ground stations to provide them with the required signal to enable them to provide you with information and other services you depend on. As you can imagine, these towers get harder and hard to find as you are cruising 11 kilometres up, perhaps over sea or desert.  Your phone, being the faithful servant that it is, tries harder by cranking up the signal strength to as much as 8 watts in an effort to enable you to view those all-important food and puppy shots.

So what, I hear you say. Well, cast your mind back to the days when mobile/cell phones switched from analogue to digital signal. When you got your new digital-enabled phone, you found the signal and call quality was nice and crisp. However, if you were ever on a call near someone with an analogue phone, you knew all about it.  It sounded like your ear was being ripped apart. This is what it can be like for the pilots, maybe not quite as extreme, but an annoyance never the less.

Let’s face it, if the use of mobile/cell phones was of major concern to flight safety then you can rest assured that leaving the responsibility of ensuring the devices were turned off would not be left to the travelling public.  There is no doubt that on every flight you will find a number of devices have been left on during a flight either due to forgetfulness or laziness.

Whether it is safety critical or not, we want our pilots to be as relaxed as possible. We want them to be able hear and be heard when they talk to the ground without the possibility of interference blurring any flight direction instructions.  So complying with the flight mode instruction still carries as much weight as it ever did.

What Does Flight Mode Do?

Flight mode on your cell or mobile.
The control centre on your mobile or cell phone.

The flight mode function on your phone or other radio-equipped device is the main control switch to turn off all radio enabled functions on your device. On your typical mobile/cell phone, this includes the voice/text, data (3g, 4g etc), Bluetooth and Wifi. You also have GPS but this doesn’t actually send anything, it sits there and listens for satellite signals and then translates them into something you understand by showing it on a map. Without data, however, you won’t get your map presentation so having GPS can be as useful as an ashtray on a motorbike.

For a few years now several airlines have been trialing and are supplying Wifi onboard their aircraft. What this means is that you have the ability now to connect to the aircraft’s onboard Wifi service and enjoy surfing the net and checking your email in the same way you can do at an internet cafe. “So hang on”, I hear you say, “I had to put my phone in Flight Mode, so how can I connect using Wifi?” Very good question and by the way, bravo for putting your phone in flight mode. As I said, Flight Mode is a master switch for turning off all radio related functions on your cell, mobile, tablet or laptop. Once they are all off you can turn individual functions back on. So seat belts on, Flight Mode on and then wait for the announcement that Wifi service has commenced and turn just Wifi on.

The Wifi signal is much weaker than your main mobile or cell call signal as it only needs to talk to a device mere metres from your seat to get a connection. This is not going to scream in the pilot’s ear so everyone is happy.

Personally, I have mixed feelings about on-board Wifi. I’ve always seen flying as a few hours you can step off the planet and leave yours and responsibilities behind with a good excuse for doing so. You know what I mean, let them miss you a little. Now I’m sure that corporate travellers will be expected to connect up and be available online or get that project completed because all resources are available. No peace for the wicked.

Flight Mode as we have seen is not going to make or break your flight as far as we can tell, but let’s show some consideration for the pilots who have to talk over the interference. Your phone charge will last a lot longer in Flight Mode, so everybody is happy.

Fly safely and LIKE us if you do.
