AIRMOD considers work on rotorcraft noise modelling guidance

29-30 March 2022 — The ECAC EAEG Aircraft Noise Modelling Task Group (AIRMOD) held its 36th meeting online. The meeting looked at the work being undertaken to develop rotorcraft noise modelling guidance. The work by the Netherlands and Switzerland on the use of NORAH helicopter noise guidance was presented, as well as updates by EASA on the development of a second version of this guidance.

The group also progressed on updating the flight performance calculations in ECAC Doc 29 Report on Standard Method of Computing Noise Contours around Civil Airports. Lastly, the group agreed on a roadmap, including its workplan for the 2022-2024 triennium.
