Re: Boeing 797 Discussion Thread - 2018

Just a general question really.Boeing says that they must make a decision by EO 2019 to be delivering the new planes by 2025. So 2020 - 2025.Obviously that an absolute max of 5 years to EIS .Is that possible for a brand new aircaft ?? ( iand it's 'new' in every possible way). Is there a recent examp...

Re: Reuters: Airbus is studying A321XLR with extended range over LR

There has been intense discussion on this forum as to whether the 797 will sport folding wings.Perhaps this revelation ( which looks like a response to the 797 ( plus plus) indicates that the Boeing product is indeed using the same (777x) technology.

Unless Airbus already have some additional range 'in the bank' I doubt the 'xlr' will have an additional 10% range myself.Thats (400nm) a big increase and a big increase in weight (fuel carried etc).But according to Leeham we may hear nothing from either AorB at Farnbrough -which would be boring!
