Local residents, businesses and visitors to the area need to be aware of the hazardous nature of activities conducted on the Range. They are strongly advised to familiarise themselves with the restrictions imposed regarding access and health and safety.

Information for Mariners

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 119.650MHz) 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.

Unidentified objects

Unidentified Objects

The MOD Aberporth Range Byelaws state that; no person shall dig, trawl, dredge or search for any projectile, or any lead, or other metal in or on the Danger Area. Due to the hazardous nature of activities that are conducted by QinetiQ at MOD Aberporth in Cardigan Bay, there is a minor risk that vessels may from time to time discover unidentified objects which may include Unexploded Ordnance (UXO).

Further guidance is contained in the Maritime and Coastguard Agency (MCA) Marine Guidance Note, MGN 323, and in the Notice to Mariners No. 5 on the UKHO website (please ensure you look under the annual tab then click item No.05)

Any person who finds any metal object, such as projectile, shell or any unidentified explosive object or part of such object should immediately contact the Coastguard VHF Ch.16.


Advanced Alert Service

Advance Alert Service

QinetiQ is always looking for ways to improve communications between the range at MOD Aberporth and the public and we often receive requests for details of our forthcoming programme. We have responded by introducing an Advance Alert Service which provides advance notice of those activities which may be more perceptible to you from time to time.

Although we will endeavour to notify you when such activities are scheduled, please note that they are subject to weather conditions and operational requirements. Any one, or a combination of these factors, may mean that the activity has to be postponed and rescheduled at short notice and it may not always be possible to provide you with an updated schedule of work.

Register for the Alert Service
