Information for Pilots

Due to the hazardous nature of the work carried out at MOD Aberporth, an Air Danger Area is established by the Civil Aviation Authority (CAA) around Cardigan Bay and West Wales, when any of the Ranges D201, D201A, D201B, D201C, D201D, D201E, D202, D202A, D202B or D202C are active.

Aberporth Air Traffic Control (ATC) provides a Danger Area Activity Information Service (DAAIS) to warn pilots of aircraft flying outside controlled airspace, when the Ranges are active.

Aberporth ATC also provide a Danger Area Crossing Service on the same frequency when activity inside the Danger Area means it is safe to do so.

Any pilot wishing to cross active Danger Areas must comply with all ATC instructions. If they are unwilling or unable to comply then they should plan to remain clear throughout the flight.

During times when any of the Danger Areas notified above are active, a Basic, Traffic or Deconfliction Service may be available from Aberporth radar, controller workload permitting.

Pilots flying in the area of any of the Danger Areas listed above should contact Aberporth Radar by radio (frequency 120.835MHz) in advance to ensure that they avoid the Ranges when they are active.

Pilots of all aircraft types, including microlights and Para-gliders, must familiarise themselves with the above restrictions.
