administrations to stations operating under authority granted by the administration concerned, for the purpose of serving one or more aircraft operating agencies. Such assignments are to provide communications between an appropriate aeronautical station and an aircraft station anywhere in the world for exercising control over regularity of flight and for safety of aircraft. World-wide frequencies are not to be assigned by administrations for MWARA, RDARA and VOLMET purposes. Where the operational area of an aircraft lies wholly within a RDARA or Sub-RDARA boundary, frequencies allotted to those RDARAs and Sub-RDARAs shall be used. Appendix designates the carrier frequencies 3 023 kHz and 27 5 650 kHz (RR 27/232 to RR 27/238) for common use on a worldwide basis. RR 27/236 permits these frequencies to be used by other mobile services for air-surface search and rescue operations. 5.111 and 5.115 (WRC-07) and Appendix 15 of the Radio Regulations also specify these frequencies for specific distress and safety purposes (coordinated search and rescue operations). The relevant provisions of Appendix 27 of the Radio Regulations are reproduced in Section 7-II Band 2 023 kHz and 5 — of this handbook. 680 kHz Appendix 27 RR 27/19 specifically recognizes the coordination role of ICAO, with particular reference to the operational use of frequencies in the Allotment Plan. This activity is coordinated at regional air navigation meetings where regional requirements and frequencies for long-range communications are agreed. Such agreements need to be registered with the ITU MIFR through the national telecommunication administrations. Appendix 27 contains provisions for adaptation of the allotment and frequency assignment procedures. These provisions allow administrations to assign frequencies which are not identified in the Allotment Plan under the condition that such frequency assignments will not reduce the protection of frequencies which are in the Allotment Plan.
