仰角(pitch)

起飛initial pitch.

一般 turbo prop(DH-8,ATR-72,Fokker-50,King Air(beech craft)...)
都在8度左右. 較大的pitch angle 會提供較大的爬升率...但相對的~
也會較為危險, in case of single engine or power on stall.

Jet plane(MD-90,737,A320/321...)
約16-18度. even single engine, can still maintain a certain climb rate.

to avoid high building or high terrain..

it could be possible to have higher initial pitch for a few miles.

but it might not be a good idea for safety reason.
