Flap retraction
Ok.. I'm bored of the ryanair private jet thread so can anyone put me straight on this..
On a normal all engines operating take off in a business jet we get airborne, romp through V2, go through the speed that the manual says the flaps can go up (V2+20 in mine) and then the most common trigger in companies I have worked for use a height trigger (400 feet for some, 1500 in the one I've just left) to retract the flaps. The challenger is regularly doing 200 ish by that point which is V2+70. I have tried to have the argument many many times that the wing doesnt care how high up it is and we should simply manage the drag the way the manufacturer intended but nobody is having any of it.
What do other people do?
