RE: Does Flap Application Cause a Pitch Down?
Most of the warbirds I've flown, Mustangs, Hurricanes, Sea Fury, T-34 (trainer), FW 190
(both short and long nose) have demonstrated a slightly nose down attitude with flaps
deployed. Most sport planes, especially high wing types have pitched up with flaps
deployed. So, I would surmise it depends on the type of aircraft and it's own
particular configuration.
