Any >problems? I don't think that coming out of reflex causes any stress on the flap system at all. I put up to 10 degrees of flap down at anywhere from 120 to 160 kts. There is no real pressure on the flaps at this small angle. Let me take that back. The amount of pressure is: at 5 degrees, sin( 5 degree) = 8.7% at 10 degrees, sin(10 degree) = 17.4% at 45 degrees, sin(45 degree) = 70.7% Therefore I am applying up to 1/4 of the force on the flaps that would be placed on them if they were down 45 degrees. That is a little higher than I thought. I will try to stay at 5 degrees until under 140 kts. So far though, no trouble. -- Lorn H.
