Re: Boeing 797 Discussion Thread - 2018

Why 50,000lb of thrust? One thing for certain it won't be 7abreast. If it is a cleansheet it is going to be big! At this point unless you are on the NMA design team and they have made a final decision there is no way you can say this with any certainty. At this point it could still be a Single Aisl...

A few people mentioned the landing gear legs have a long lead time. Surely Boeing would just use the 767 landing gear legs and trucks with potentially smaller wheels/tyres. The 767 landing gear might be a smidge too heavy/strong on paper at 180T MTOW but the 797 will most likely designed for more l...

Resurrecting the 787-3 (with a 52m wing to fit in Code D gates) would be a lot cheaper than NMA. Personally I don't see MOM as 8W as it's too close to 787 in capacity. Marginal gains for a huge investment.

An oval 7W NMA/NSA combined two wing/two gear program makes a lot more sense to me.
