B737 Flap Extension above 20000'
The B737 has a limitation of not extending the flaps above 20000'. Does this also imply that one cannot go ABOVE 20000' with flaps extended? For example, say the flaps would not retract after Takeoff and the departure airport was below landing minima, could one divert to another airport at a flight level above FL200?
Does anyone know the reason for the 20000' restriction?
Thanks all.
