Re: Emirates renegotiating 777X order

777-8 orders - Emirates : 35 - Qatar : 10 - Ethihad :8 That's it, nobody else over the last (booming) 5 years. If you have A359s on order, SQ flies 20 hour flights with them. QF does PER-LHR with a 787-9, what the usp? SQ isn't doing 20 hour flights. EK needs payload haul as does DL. QF needs the j...

Re: Boeing 737MAX Grounded Worldwide Q3 2019

We don't know key technical information. For example, the increased lift of the engine nacelles has been mentioned many many times, but it's not clear why that should change the stick gradient . If the nacelle behaves like an annular airfoil, annular airfoils tend to stall late, beyond the 15 or so...

Re: Emirates renegotiating 777X order

The 787-10 weighs 6,650kg more than the 787-9. The 787-9 burns 5600kg of fuel per hour. So the empty weight difference is only 70 minutes worth of fuel. At a cruise speed of 490knots it means the 787-10 range should be 600nm shorter. But in the real world the range difference is twice that. The 787...
