Full Description

In Volume I, different aircraft classifications form the basis of noise certification. These classifications include subsonicjet aeroplanes for which application for the certification of the prototype was accepted before 6 October 1977; for thoseaccepted on or after that date; for propeller-driven aeroplanes over 5 700 kg; for those not exceeding this mass; forsupersonic aeroplanes for which application for certification of the prototype was accepted before 1 January 1975; andfor helicopters for which the application for certification of the prototype was accepted on or after 1 January 1980.

For each classification of aircraft type, a noise evaluation measure has been standardized. Except for propeller-drivenaeroplanes not exceeding 5 700 kg maximum certificated take-off mass, the noise evaluation measure is the effectiveperceived noise level, expressed in EPNdB. The EPNdB is a single number indicator of the subjective effects of aircraftnoise on people, taking into account the instantaneous perceived noise level and duration.

Various measurement points, maximum noise levels at lateral, approach and flyover noise measurement points, alongwith flight test procedures, have been designated for these types of aircraft.

Noise certification is granted by the State of Registry of an aircraft on the basis of satisfactory evidence that the aircraftcomplies with the requirements which are at least equal to the applicable Standards set out in this Annex.
