When undertaking offshore wind farm aviation studies one needs to consider Aviation Warning Lights. According to UK Government Legislation wind turbines above a specific height need to be fitted with Aviation Warning Lights.
On the 27th of April 2012 the Civil Aviation Authority (CAA) published guidance regarding the actions that need to be undertaken in the event of aviation lights failure. Key points are:
- The person in charge of the Wind Farm is responsible to to repair or replace the light.
- It is accepted that in the case of an Offshore Wind Farm there may be occasions when meterological or sea conditions, among other, may prohibit the safe transport of staff for repair tasks. In such cases a Notice to Airmen (NOTAM) should be issued.
