Well I just wanted to see a "legal" point of view for minimum height of turn. It makes sense to climb straight ahead for a while and then turn. Sane ATC wouldn't just give you a departure clearance (without condition) into terrain, even in Morocco (I hope that I am not too naive by trusting these guys a bit). So is there any other reference for minimum turning without SID?
Turns are not permitted in the takeoff climb path below a height of 50ft or a height equal to one half of the wing span, whichever is the greater, above the elevation of the horizontal plane at the end of the TORA.
Between this height and 400ft max angle of bank is 15°, above 400ft 25°.
