Re: Which Frame Will Be More Efficient....The A35J or the 779?

Airbus could, and arguably should, torpedo the 777X business case by re-engining A350 with Ultrafan next decade. That is if they are able to adopt ultrafan bypass ratio's on the A350 in a profitable fashion. They probably will but would probably require more work than re-engining the A320 and A330 ...

Re: Should Airbus focus on A220 product increase instead of A320 mid-term?

Airbus can concentrate on building A220 both -100 and -300. An A220-500 would have first to be designed, launched and so on. If a decision is made for it one could see that frame at the earliest 2026 and more likely later. We don't know if it has to designed first. In fact, as others have pointed o...

Re: Should Airbus focus on A220 product increase instead of A320 mid-term?

If Airbus/Bombardier start thinking about a bigger model, one has to look when a 5 across 220 starts to loss efficiency against a 6 across A320. That could through a damper on the enthusiasm for the A220-500. The A220-300 is already longer than the A320. The stretch of the A220 to A320 capacity cou...

An A320 is probably not more expensive to build and sells for more at his stage. Indeed; "at this stage". That's part of my point, at this stage. Increasing rate on the A220 mid term will reduce cost per plane more than on the A320. Also a A220-500 would only overlap seatcount. Not payloa...
