Re: A350-2000 Doable with new technologies, more potential with 787 : Bregier

One B787-10ER would be a A350 killer........one B787-10 with 7500nm would be the number 1 in the widebodies world. No it would be a waste of money. Pure fantasy on this forum. The 787-10 currently hits maximum takeoff weight with a normal payload and about 80% fuel capacity. It can only fill its fu...

It sounds like they just may be contemplating launching MOM and NSA at the same time using the same nose/barrel with two different wings/wing boxes.

Re: Is it time for Three Engine Hybrid Aircraft?

A big problem with such an aircraft, at least with battery tech that is even close to what is feasible today, is the massive size of the battery that is inevitably needed just for take-off, which then becomes dead weight through the rest of the trip.

Re: Boeing officially forms program office to flesh out 797 plans

Design it for 4.5K to start and overtime (by mid 2030's) I'm sure with PIP's and optimization it will grow to be a 5.5K aircraft.

They have to think about how the aircraft will evolve over time. If they start at 5.5k it will end up being a 6.5-7.0k frame in 15-20 years from EIS.
