Due to the hazardous nature of the work carried out at MOD Hebrides Ranges, Air Danger Areas are established in the airspace above and to the west of the Uists, when any of the Ranges EGD701A to EGD701Z inclusive are active. The active areas are notified to pilots by Notice To Airmen (NOTAM). Pilots can access NOTAM information via the UK Aeronautical Information Publication.
Scottish Information on 127.275 MHz provides a Danger Area Activity Information Service (DAAIS) to warn pilots of aircraft flying outside controlled airspace, when the Ranges are active. Additionally, Benbecula Aerodrome broadcasts Range activity information as part of an Automatic Terminal Information Service (ATIS) on 113.950 MHz. Pre-flight information can be obtained from Range Control on 01870-604449.
Pilots of all aircraft types, including microlights and Para-gliders, must familiarise themselves with the above restrictions.
