Draft PPS18: Renewable Energy
Annex 1 Wind Energy Planning Issues: Risk of Collision
A98. Risk of collision is likely to occur close to civilian and military airfields, and in military low flying zones. As appropriate, the Department consults with the relevant licensed operators of civil airports/airfields, the Ministry of Defence (MOD) and the National Air Traffic Service (NATS) on all proposals for wind turbine developments in Northern Ireland. The Civil Aviation Authority (CAA) can inform the applicant of any civilian airfields that are likely to be affected, but it is the responsibility of the applicant to consult the airfield management at the airfield in question. It is recommended that such consultation should occur prior to submission of an application and the applicant should take account of the airfield management’s requirements, which will depend on local topography and the preferred flight paths at the site.
A99. In the interests of aviation safety, lights may be required on wind turbine development and is mandatory in all cases where the structure exceeds 150m high. In addition, structures over 91.4m (300ft) are required to be charted on aviation maps. Developers will be required to provide details of the development to the Defence Geographic Centre.
A100. There is currently no low flying training undertaken by the MOD in Northern Ireland.
