The noise propagation of three projected STOL aircraft was investigated during takeoff and approach flight. It was shown that takeoff noise can be reduced a few dB by thrust reduction (three segment takeoff profile) near airports. As with CTOL aircraft, the landing paths should be as steep as possible, and landing flaps and gear should be lowered at low altitude. By using all possibilities during landing, obtainable noise reduction can be considerable. Keeping to the exact flight path was also found to be noise reducing.
