captaink,
I have seen figures for ranges in excess of 2000 nm for the -500 is this correct, what sought of payload will you get at max fuel for range, what is the range ?
Some more questions if you have time ..
What is the best height for best TAS, what are the planned fuel flows for cruise, allowances for climb, and taxi ?
What is the standard cruise heights for 300, 500, and 700 nm sectors, and time to climb ?
What is the single engine cruise height ?
What is the single engine cruise speed ?
Thanks
