Re: Turkish Airlines could start flying to Australia in 2019 with B787-9

This has been misreported. The route will use their A350's. The 787-9 can't do SYD-IST unless it has 120-150 passengers. The standard 280T A350-900 can carry twice as many passengers that distance. These are the exact routes that justify a split fleet of 787's and A350's. You put the A350's on the u...

Re: Germany Considers Tornado Replacement

To spend $10+ billion and develop something identical, no level headed western government would do. To spend $5 billion and develop something far less capable than the F-35 is also illogical for such a small number of aircraft. The F-35 covers far more requirements than Germany needs.

The fuel burn reduces as the aircraft gets lighter. Fuel burn reduces as the aircraft flies higher. Fuel burn reduces if an aircraft flies at mach 0.85 instead of mach 0.9.

The 787-9 burns approximately 1.5% to 2% less fuel than the A350-900 with the same payload weight. This is because the 787-9 is a lighter frame with slightly less cabin area, less wetted area and less drag. However with the same payload weight in both aircraft the A350-900 would be less dense and mo...
