29. Frequencies used for particular functions
(1)The emergency channel, 121.500 Megahertz, shall be used only for genuine emergency purposes, as outlined in the following—(a)to provide a clear channel between aircraft in distress or emergency and a ground station when the normal channels are being utilized for other aircraft;(b)to provide a very high frequency communication channel between aircraft and aerodromes, not normally used by international air services, in case of an emergency condition arising;(c)to provide a common very high frequency communication channel between aircraft, either civil or military, and between such aircraft, and surface services, involved in common search and rescue operations, prior to changing when necessary to the appropriate frequency;(d)to provide air-ground communication with aircraft when airborne equipment failure prevents the use of the regular channels;(e)to provide a channel for the operation of emergency locator transmitters, and for communication between survival craft and aircraft engaged in search and rescue operations;(f)to provide a common very high frequency channel for communication between civil aircraft and intercepting aircraft or intercept control units and between civil or intercepting aircraft and air traffic services units in the event of interception of the civil aircraft.(2)The frequency 121.500 Megahertz shall be provided at—(a)all area control and flight information centres;(b)aerodrome control towers, approach control offices serving international aerodromes and international alternate aerodromes; and(c)any additional location designated by the appropriate air transport safety authority, where the provision of that frequency is considered necessary to ensure immediate reception of distress calls or to serve the purposes specified in subregulation (1).(3)The frequency 121.500 Megahertz shall be available to intercept control units where considered necessary for the purpose specified in subregulation (1)(f).(4)The emergency channel shall be guarded continuously during the hours of service of the units at which it is installed.(5)The emergency channel shall be guarded on a single channel Simplex operation basis.(6)The emergency channel (121.500 Megahertz) shall be available only with the characteristics as contained in the Civil Aviation (Surveillance and Collision Avoidance Systems) Regulations, 2018.(7)An air-to-air very high frequency communications channel on the frequency of 123.450 Megahertz shall be designated to enable aircraft engaged in flights over remote and oceanic areas out of range of very high frequency ground stations to exchange necessary operational information and to facilitate the resolution of operational problems.(8)In remote and oceanic areas out of range of very high frequency ground stations, the air-to-air very high frequency communications channel on the frequency 123.450 Megahertz shall be available only with the characteristics as specified in the Civil Aviation (Surveillance and Collision Avoidance Systems) Regulations, 2018.
