Helikopter - EGNOS basert innflyging

Fint, dette kan bidra til at opplevet støy, spesielt fra S-92A, kan reduseres:
Eurocopter demonstrated new automated landing procedures relying on Egnos (Europe’s Waas equivalent) satellite guidance. Part of Europe’s Clean Sky research project, the tests were performed on an EC155 medium twin. They showed significant reductions in the helicopter’s perceived sound footprint, the company said. The noise-abatement flightpaths were compatible with IFR operations and can be tailored to local requirements.
