Adaptive high-lift system contains the double-slotted flap deflected. Calculations shown increase the lift coefficient by 15%. Test are shown what the lift coefficient increases by 11–13%. Range of propeller load coefficients ?=0.5?1.5 increases the lift coefficient by 25% and 36%, respectively. Adaptive element facilitates the decision of the problem of longitudinal trimming of the airplane.
