Boeing 787

The Boeing 787 8 Dreamliner is a mid size, twin engine, wide body jet developed by the Boeing company.

The decision to develop such a plane was brought about by the need for a replacement for the Boeing 767 which was experiencing falling sales, due to stiff competition from the Airbus A330-200.

Boeing 787 New Technology

Boeing states that the Boeing 787 is a much more fuel efficient aircraft, due to technological advances in aerodynamics, more efficient engines, and reduction in weight. The reduction in weight is attributed to the use of composite materials for most of it’s construction, as well as more advanced systems such as electric pumps used in place of hydraulics. The Dreamliner comes in at 30,000 to 40,000 lbs lighter than Airbus A330 200.

The initial design of Boeing 787 8 featured a very rakish nose and cockpit windows and a very dolphin like vertical stabiliser (tail). The final design has settled on a more conventional vertical stabiliser as well as reduced rakishness to the nose.

Not only is the Boeing 787 a very technologically advanced aircraft, but the way in which it is constructed is also quite new for Boeing. The actual components are constructed in locations all over the globe, and brought together at Boeings Everett plant. The target is to be able assemble the completed aircraft in Everett in three days. See the assembly page for more details.

Boeing 787 Rollout

When the Boeing 787 program was first launched, the aircraft was known as the Boeing 7E7, and depending on the audience, Boeing would say it stood for ‘environmentally friendly’, ’efficient’, but in the end they said it simply stood for Eight. See the history page for more details.

The aircraft launch has suffered many delays, however, there was an official roll out of the prototype in Everett on the 8th of July 2007, which in American date format of course is written, 7/8/7.

The maiden flight of prototype aircraft finally took place on 15 December 2009.

    1. Hi Jason,
      That is a good question. There are three main fuel tanks on the 787, the centre tank which stretches from one engine through the wing box to the other engine, and two out board tanks which stretch from the engines out toward the wing tips.
      The capacity of these tanks is as follows:

      Boeing 787-8
      Centre Tank – 84,036 Litres (22,200 Gallons)
      Left and Right tanks (each) – 21,085 Litres (5,570 Gallons)

      Boeing 787-9
      Centre Tank – 84,566 Litres (22,340 Gallons)
      Left and Right tanks (each) – 20,895 Litres (5,520 Gallons)

      I hope that helps.

      Cheers Peter

    1. Hi Ethan,
      thanks for stopping by. You pose a great question and as usual in aviation, there isn’t a single definitive one size fits all answer.

      For each flight these three speeds need to be calculated using a whole list of variables which include; wind, temperature, barometric pressure, runway altitude, runway condition, runway slope, runway length, obstacles beyond the runway and probably a few I’ve missed. The reason for this is that each speed has it’s basis on what the aircraft can do in the case of an engine failure. Of course on the Boeing 787 an engine failure means you have half the engines you started out with, so a 50% reduction in available power and the challenges of asymmetric flight thrown in. So what do the speeds mean?
      V1 – V1 is the speed at which point you are passing the point where stopping on the ground with an engine failure is no longer an option. This of course takes into account all the factors above to calculate a safe stopping distance for that particular time at that particular airfield.
      VR – VR or rotate speed is that speed at which the control column can be pulled back to lift the nose of the aircraft and thereby start generating lift under the wings. Sometimes V1 and VR can be simultaneous. For this reason the Airbus A380 and the Boeing 787 both have the V1 notification issued by the flight computer as as automated voice. Because the system cannot generate both notifications at once the pilot not manipulating the controls still gives the VR notification.
      V2 – V2 is the speed at which the aircraft can safely climb out with a failed engine. Once again this will be very dependant on the conditions around weather and location. A rule of thumb says that around 165 knots is a ball park target.

      I hope that answers your question. Please by sure to share.

      Cheers Peter

  7. Hi.
    What would be the minimum sea level runway length required for a B787-9 operating a 3 hour block to block service with a full load of pax (say 270), assuming 2 hours reserve fuel.

    1. Hi Larry,

      great question. I have looked but can’t seem to find that data anywhere.

      Anyone who might have access to those table might like to give Larry and answer.

      Thank you.

      Cheers Peter

    Hi There,
    I have a question, is it true that Boeing 787 wing flex 26 feet at max load.Its an unbelievable.
    If you have video as such,please share with me.This view will be spectacular I guess.

  10. 1. The Boeing Air Liner is New Plane on market to Sell on market too! The Batteries Problem been solves to put a Steel Casing Around Batteries do catch Fire too. While the Boeing was in Flight too! Problem been solved too. By Boeing Mfg of 787 Air Liner too! Do you Agree? Sir? Or Mam? What does the Public say about this Battery Incident do catch Fire in Flight too! They are Special Batteries Boeing put in Air Inner Jets too. They Put Steel Case Around the Battery An it Seal over the top of it too! Problem is solved too! By Boeing Air Liners Mfg co.

  12. What is the minimum takeoff length for 787-8 aircraft flying from Richmond NSW to LosAngeles USA with 20 people on board

    Can it take off under 2000 meters

    1. Well considering Richmond is as good as at sea level and the takeoff run with MTOW is 2,600 Mtrs, it’s fair to say that you should lift off within 2,000 Mtrs with your reduced load. Atmospherics such as temperature, air pressure and wind along the runway will also affect your performance. Of course, you’ll need to calculate your fuel required plus reserve to know the weight.
