Predicting aircraft noise with AZB 2.0 - a best practice model being revised

Description: The German aircraft noise calculation model AzB (Anleitung zur Berechnung von Lärmschutzbereichen) has been developed for defining noise protection areas by assessing the noise of a predicted air traffic scenario. The AzB data base was specially designed for this purpose and it consists of 36 aircraft classes comprising civil and military jet aircraft as well as propeller-driven aircraft and helicopters. In the last decades the traffic mix has changed considerably. The share of aircraft complying with ICAO Annex 16, chapter 3 in the total air traffic volume has â€Ìat least in Germany - almost fallen to zero, whereas several aircraft with significantly lower noise emissions have been put into service. Advances in noise mitigation have also been achieved due to optimized flight operations (noise abatement departure procedures suiting to population structure, CDO, steeper approach...) Although parts of the AzB were revised and amended in 2006/2007 , its data base corresponds essentially to that published by the German Environment Agency (UBA) in 1999. The acoustic and operational data of the AzB are of limited suitability as a means of representing new and prospective aircraft types. To meet the requirements for accuracy and to achieve good accordance with measurements, the German Aerospace Center (DLR) is updating the data base of the AzB on behalf of the German Environment Agency. In this contribution an overview of the recent developments is given and first results of the research project are presented. Quelle: https://icsv26.sched.com
