MANEUVERING AFTER TAKE-OFF

Featured Replies

Hello again, I just came across a diagram showing the take-off procedure and climb out. One thing caught my eye was this remark at 1000Ft "15 degree bank limit until reaching maneuvering speed for configuration" I know there is no 40 degree bank protection if you retract -20knots below maneuvering speed but I thought you can retract your flaps -20 below maneuvering speed and still bank 25 degrees. Or does this just mean that you cannot turn while retracting flaps? Plus lets say flaps 5 is set does the -20Knots retraction below flap 1 bug mean you that you have to be at the flap 1 bug by the time the flap runs to the 1 position? I hope I don't sound too confusing here. :-wave Thank You

Thanks for the sites, just one more thing the site did not specify. Is it ok to retract the flaps while in a turn? I perform some departures where I need to make a long turn to head towards my point. Can I retract while turning? Or should I fly straight? Thank You

I have no idea with regards to the 767 but I have been taught not to move the flaps while turning (GA aircraft) as there is potential for disaster if the flaps somehow should split and leave you with more flaps on the upper wing. You might not be able to roll out of the turn.

Hi FEll'asKb, I'm not sure what you mean by the flaps would 'split' but in GA it's perfectly ok to retract the flaps during a during a turn of less than 15 degress angle of bank, as long as you are well above the minimum control speed for that setting. I wouldn't advise a slow speed turn and extending the flaps though, in GA aircraft, as flaps effectively increase the angle of attack of a wing. If you're in a turn, of say 25 degrees, the inner wing is travelling slower than the outer wing...extending the flaps increases the angle of attack on the inner wing to the point where it could stall and lead to auto rotation...I've seen it happen once before in real life, and there were no survivors. That was in a C152.In Jet aircraft, I think airlines have SOP's concering flap retraction/extension during a turn of so many degrees, but I think it's generally ok as long as you are not increasing your load factor too much and your speed is providing a comfortably safe margin.Cheers[br]obklogo.gif[/img][/font][/b]

A situation where the flaps somehow would malfunction and only extend/retract on one of the wings. I have no idea how it would happen but you gotta trust your instructor, right? :-)The second point is very valid though. It is obviously a situation as that one where the use of flaps while turnings is as most tempting, i.e. turning final.
