Boeing 747 Specs - Modern Airliners

Boeing 747 Specs

The design and building of the Boeing 747 was an audacious leap forward in aviation. The demand to relieve congestion at airports struggling with the influx of a growing travelling public was to be solved by offering fewer aircraft with higher carrying capacity. An aircraft with a carrying capacity double that of the existing workhorses, the Boeing 707 and Douglas DC8, was required. Thus the Jumbo was born. Let’s take a look at the Boeing 747 Specs to better understand this Queen of the Skies.

Strangely enough, it wasn’t the extra carrying capacity that attracted early customers of the aircraft, but longer range compared to other aircraft of the day.

The ability to consider designing such a large aircraft was made possible by the introduction of the High By-pass Turbo Fan engines that were able to deliver much higher thrust at a much-reduced fuel burn rate compared to pure jets in use at the time.

The four-engined Boeing 747 was designed to be the safest airliner so far built. Redundancy was in place for systems such as hydraulics, where a back up was available should the main system fail. There were dual control surfaces to enable the continued control of the aircraft should any of the surfaces fail. There were four main landing gear bogies each with four wheels. This was not only to spread the weight of the aircraft more evenly, but the 747 was capable of landing on two opposing bogies if necessary.

Everything about the 747 compared to other aircraft in use at the time of its initial launch, was on a grand scale. For instance; 147,000 pounds (66,150 kg) of high-strength aluminium is used in its construction, 171 miles (274 km) of wiring along with 5 miles (8 km) of tubing is used, six million parts are used, half of which are fasteners.

Air New Zealand Boeing 747 400. For many years the 747-400 was at the pinnacle of the Boeing 747 Specs.
An Air New Zealand Boeing 747 400 takes off from Christchurch, New Zealand.
QANTAS was one of the airlines that ordered the 747 SP. Due to its many long routes QANTAS benefited from the long range capabilities of the 747 SP without excess seat capacity. In January 1981 the SP was brought to Wellington New Zealand for a promotional and testing flight. Wellingtons' runway is notoriously short and with water at both ends and fluky winds is a challenge at the best of times. The 747SP was the only 747 to ever have had scheduled services into Wellington.

The arrival of the QANTAS 747 SP was quite an event. The hills surrounding the airfield were lined with spectators waiting for this giant of the skies to descend out of the cloud. It was a sight to behold at this little capital city airport. The only other 747 that had landed here was a Pan Am 747 100 which had to divert from Auckland and couldn’t make it to Christchurch. To get it off the ground again, they had to remove the seats and send them to Auckland on the train.

  1. Do you know where I can find info on the first groups of 747s delivered to TWA by Boeing. My Dad was a captain and I am curious if he flew the Flt 800 aircraft or not.

        • Hi E P,

          taking the 747-400 there is a range for this height measurement which of course is due to the weight of the aircraft. When the aircraft is loaded it will sink down furthe ron its suspension and tyres.
          That range is:
          Minimum 29 feet 7 inches / 9.02 metres
          Maximum 31 feet 4 inches / 9.56 metres

          I hope that helps.

          Cheers Peter

    • Hi Amanda,

      there are 10 main deck doors and looking at the 747-400 in this case, all the doors, including 4L(4 left), are the same dimensions.
      Opening size = 1.07 x 1.93 Metres (42 x 76 inches).
      Overall door size = 1.19 x 1.93 Metres (47 x 74 inches).

      Door 4L is 40.74 metres (133 feet 8 inches) back from the nose of the aircraft.

      Can we ask why 4L in particular?

      Cheers Peter

  2. Was just curious as to who were the original airline customers who booked the 747 in 1968/69
    Obviously there are a number of cabin crew & logos on the launch aircraft, but the names of each airline that booked the first lot are nowhere to be seen, I can see that PanAm TWA JAL Air India were there
    Would love to have the full list of original airlines

  3. Hi there – is there anywhere i can look up the dimensions of the first class cabin in the 747? I’m thinking about converting my downstairs music room to have that unique cone-shape. Could be cool!

    • Hi Stu,

      cool idea. We haven’t been able to find the measurements. We wish you luck. If you ever get it done, we’d love to see a picture of the finished result.

  4. Hi,
    I’m doing a task for my school report and I need to compare the earliest and latest models. I was just wondering what the operating empty weight for the Boeing 747-100 is, I couldn’t find information on it but I could found it for your 747-8 page.

    I also noticed that there is much more information for the 747-8 than there is for the 747-100. Do you know where I could find the missing information for it?

    • Hi Anne-Sophie,

      thanks for stopping by and pointing out the shortfall. Please check again as we have added the missing information. Also at the bottom of the page is a link to a very detailed document of the Boeing 747 Specs for 747 100, SP, 200, 300 and 400 provided by the European EASA.

      I hope you find what you need.

      cheersa Peter

    What are the fuel type used?
    What are the weights when empty?

    • Hi Sophie-Anne,

      What is the fuel efficiency?
      Well, that is a bit of an open question. For example, if you drive your car in the city, then you are going to burn a lot more fuel than you would on a long freeway drive. The same applies to aircraft. If the Boeing 747 flies a short hop say from Sydney to Melbourne, it will be less economical than a Sydney to Los Angeles flight. The 747 is designed to fly at a high altitude so that it passes through thinner air with less friction or resistance. Less fuel required to push it forward. The weight factor might stop it from getting to that higher altitude straight away at the beginning of the flight. Full of fuel at the beginning of the flight, it has to stay at a lower altitude for the first few hours until it has burned off enough fuel to make it lighter and able to climb to that higher optimum altitude.
      Talking about fuel efficiency, we also need to consider the load on board. This is where we talk about seat kilometres. How much fuel does it take to move one seat a certain distance? Those filled seats, and the cargo below, are what pay for the flight. So the more filled seats you are moving, the more seats that are paying toward the cost of running the aircraft. A half-empty aircraft means that each seat is contributing more to the running cost and therefore, there may be very little profit, or perhaps even a loss.
      So, how much fuel does a 747 use? If we look at a Boeing 747 400 carrying 450 passengers at cruising altitude, we can expect to be burning about 4 litres per second, or around 10 to 11 tonnes an hour.

      What is the fuel type used?
      Basically, jet fuel is kerosene. There are various refinements, but the main types are:
      – Jet-A. This is used in the U.S. only and has a freezing point of -40C
      – Jet-A1. It is pretty much the same as Jet-A but has a lower freezing point of -47C.

      What is the weight when empty?
      Those weights have been added to the table above.

  6. Wow, a blast from the past. I remember flying in the 747SP from Sydney to LA and the thrust you felt in the seat was like having a V8 in a small car. That plane was awesome and you can see the cruise speed at 990KPH is 100KPH faster than anything today. If only Boeing would do a special like that with say the 777LR they would get a longer range and a faster travel time, maybe even push the boundary of 1000KPH. I’m surprised they haven’t thought of it. But thank you for this page as it brought back great memories I had as a teenager flying the 747SP from Sydney to LA.

      we’re glad you enjoyed a trip down memory lane. It was an exciting time in aviation where everything seemed about getting bigger and faster.
