APPENDIX 1. PRINCIPLES GOVERNING THE IDENTIFICATION OF RNP TYPES AND THE IDENTIFICATION OF ATS ROUTES OTHER THAN STANDARD DEPARTURE AND ARRIVAL ROUTES Chapter 2, Sections 2.7 and 2. I l refer Note.- See Appendix 3 concerning the identijication of standard departure and arrival routes and associated procedures. Guidance material on the establishment of these routes and procedures is contained in the Air Traffic Services Planning Manual Doc 9426. 1. Designators for ATS routes and RNP types 1.1 The purpose of a system of route designators and quired navigation performance RW type applicable to specified ATS route segment, routes or area is to allow both pilots and ATS, taking into account automation requirements c be usable by both ground and airborne automation systems d permit utmost brevity in operational use and e provide sufficient possibility of extension to cater for any future requirements without the need for funda- mental changes. 1.3 Controlled, advisory and uncontrolled ATS routes, with the exception of standard arrival and departure routes, shall therefore be identified as specified hereafter. 2. Composition of designator a to make unambiguous reference to any ATS route 2.1 The ATS route designator shall consist of a basic without the need to resort lo the use of geographical designator supplemented, if necessary, by coordinates or other means in order to describe it a one prefix as prescribed in 2.3 and b to relate an ATS route to a specific vertical structure of the airspace, as applicable b one additional letter as prescribed in 2.4. c to indicate a required level of navigation performance 2.1.1 The number of characters required to compose the accuracy, when operating along an ATS route or within designator shall not exceed six characters. a specified area and 2.1.2 The number of characters required to compose the d to indicate that a route is used primarily or exclusively designator should, whenever possible, be kept to a maximum by certain types of aircraft. of five characters. Note I.- Prior to the global introduction of RNP, all references in the Appendix to RNP also apply to area navigation KNAV routes, where navigation performance accuracy requirements have been specified. Note 2.- SpeciJications governing the publication of RNP types are given in Annex 4, Chapter 7, and Annex 15, Appendix 1. Note 3.- In relation to this appendix and for flight planning purposes, a prescribed RNP type is not considered an integrul part of the ATS route designator. 1.2 In order to meet this purpose, the designation system shall a permit the identification of any ATS route in a simple and unique manner 2.2 The basic designator shall consist of one letter of the alphabet followed by a number from 1 to 999. 2.2.1 Selection of the letter shall be made from those listed hereunder a A, B, G, R for routes which form part of the regional networks of ATS routes and are not area navigation routes b L, M, N, P for area navigation routes which form part of thc regional networks of ATS routes c H, J, V, W for routes which do not form part of the regional networks of ATS routes and are not area navigation routes d Q, T, Y, Z for area navigation routes which do not form pan of the regional networks of ATS routes. b avoid redundancy ANNEX 11 4/11/99 No. 39
