Shows what happens if I try and do something from memory without having finished the course - hehe. I have to say you have confused me a little though
I had a quick look at the notes on my laptop. Best range is of course Vimd. Best climb for a prop will be somewhere between Vimp and Vimd as the power available from thrust falls rapidly as you climb. For glide, the speed is Vimd because that is the best EAS over Drag ratio and there is no thrust other than gravity in the equation.
Assuming your 11/1 glide ratio then glide ang = inverse tan(11/1) = 85 deg. So the glide angle is 5deg. 1000kg * cos(85)(or *sin(5)) = 87kg less lift.
A tad more than 1/121. Hell! I'm not sure if this is right or not. Anybody else?
