Research on compliance of noise airworthiness requirements for civil aircraft manufacturer

International Civil Aviation Organization (ICAO) has formulated aircraft noise requirements - ICAO Annex 16 Volume I "Aircraft noise", which requires that aircrafts must undergo and achieve noise airworthiness certification before putting into service, otherwise the airworthiness certificate will not be issued. Based on type-certificate data sheet for noise (TCDSN), this paper studies the noise compliance of mainstream aircrafts of foreign manufacturers in detail, and discusses and analyzes the variation law of three single point noise levels of flyover, lateral and approach, and cumulative noise level with the maximum take-off weight. The results of the study have a certain reference significance for guiding the preliminary evaluation of the impact of the change of maximum take-off weight on the airworthiness noise level during the change of model design.
