Night-Time Marking Of Wind Turbines

The Austrian Federal Government plans to amend the Austrian Aviation Act (Luftfahrtgesetz; LFG) to allow for on-demand night-time marking of aviation obstacles, such as the beaconing of wind turbines.¹ This is intended to reduce light emissions, especially at night.

1. General

Aviation obstacles may generally only be erected with an exemption permit from the aviation authority.² Additionally, aviation obstacles above a certain height must currently be marked with continuously red flashing lights due to international agreements (Chicago Convention on International Civil Aviation; ICAO Manuals) and national regulations (LFG) to maintain aviation safety. This continuous red flashing, even at night-time, is now set to be a thing of the past.
