For 280t MTOW variant, we will have 108t of fuel. We know A350 consumes 5.85t/hr in a typical URL flight. So this will be an 18.5 hours bird. EWR -> ...

Re: Updated: Qantas saying it is almost ready to select Project Sunrise aircraft

777-8 having the same MTOW as 777-9 is essentially the "shrink" version of later. The long range fuel economy performance of 777-9 is little ahead of A35K. While A35K is more efficient than 777-8 by a not insignicant amount, assuming a 8000 nm still air mission. On a 8500nm mission, A35K n...
