Unloading the wing

Hi,

PJ2,

unloading the wing is used to prevent entering a stall, even when the aircraft is well below its normal level flight stall speed.

The concept is clear: Stall is a function of weight to be lifted (by the airfoil) and beyond a certain AOA there is a fast degradation. Unload means "help" the wing (to do the lift) "reducing the weight" using physics.
