Noise propagation from STOL aircraft taking off and in the landing approach is investigated on 3 STOL designs. It shows that takeoff noise can be reduced by several db by reducing the thrust (three segment takeoff) in areas near airports. Just as with CTOL aircraft, the landing paths should be as steep as possible and landing flaps and gears should only be lowered at a reduced height. The noise reduction achievable by using all possibilities in landing is considerable. Sticking to the path also diminishes noise. (Author)
