What speed does an airplane need to take off?
The speeds needed for takeoff are relative to the motion of the air (indicated airspeed). A headwind will reduce the ground speed needed for takeoff, as there is a greater flow of air over the wings. Typical takeoff air speeds for jetliners are in the range of 240–285 km/h (130–154 kn; 149–177 mph).
Why does the 787-10 have a higher MTOW than other variants?
Actually it is easier for the smaller variant to get a MTOW increase. The wing and wingbox had to be strengthened for the 787-10. The heavier fuselage increases the wing root bending moment at any given flying weight. You have more fuselage drag and more thrust with the associated loads.
How is the weight of the Boeing 787 being reduced?
Weight is being reduced by the fact that up to 50% of the aircraft is built using composite materials, including the fuselage and wings. To put this in perspective, compare the Boeing 787 with Boeing’s top-selling Aircraft, the Boeing 777.
What is the Boeing 787-9 Dreamliner?
The Boeing 787-9 Dreamliner is a two-engined long-range widebody airliner with a capacity of 257 – 290 passengers produced by the American manufacturer Boeing Commercial Airplanes. The 787-9 is a member of the Boeing 787 Dreamliner Familie (787-8, 787-9 und 787-10). The 787-9 is a stretched variant of the Boeing 787-8…
Will the Boeing 787-9 make it to New York/Sao Paulo?
“While its current 787-9 fleet is not able to make New York or Sao Paulo, Boeing is working on increasing the 787-9s maximum takeoff weight by around 10% or 2.5 tones. The higher MTOW variant should be available by 2022 and improve the feasibility of New York-Auckland and Sao Paulo-Auckland”
