The noise, at car level, of Dornier DO 27 and 28, Beech 65, Piaggio Pi 149 D and Cessna 207 aircraft was measured during typical flight phases on the runway, during takeoff, and during cruising. Results were tabulated. It is shown that the noise level of the different aircrafts can be classified, transforming the dB (A)-level into a dimensionless characteristic performance number, which is a measure for the effective engine performance as a percentage of the continuous performance.
