Thanks John.


Ok here's a couple of very basic numbers. A quick look so I'm not saying it's 100% accurate.

We don't know whether he took of flapless or with flap, so this has nothing to do in relation to the accident aircraft.


Let's assume flap is used for takeoff. Raisbeck FAR 25 info.
20 degree day, 500 elevation, nil slope and wind, 50ft obstacle height, MTOW.

TODR 2600ft (790m).
Net climb gradient, inop feathered, gear up, flaps t/o: 3.6%
Balanced field (obst height 35ft), 3850-4250ft (1170-1290m) [depends on your brake/tyre combination].
V1 Vr 99, V2 100, V50 105.


Accelerate go, to 35ft, non FAR25 info.
Max weight, flap up, nil wind and slope, 500 elevation, 20 degrees- 3800ft (1160m).
