1. The basic designator consists of one letter of the alphabet followed by a number from 1 to 999. The letters may be:

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 the regional network 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 part of the regional networks of ATS routes;

2. When applicable, one supplementary letter shall be added as a prefix to the basic designator as follows:

a) K - to indicate a low level routes established for use primarily by helicopters

b) U - to indicate that the route or portion thereof is established in the upper airspace

c) S - to indicate a route established exclusively for use by supersonic aircraft during acceleration /deceleration and while in supersonic flight

3. When applicable, a supplementary letter may be added after the basic designator of the ATS route as a suffix as follows:

a) F - to indicate that on the route or portion thereof advisory service only is provided;

b) G - to indicate that on the route or portion thereof flight information service only is provided;

c) Y - for RNP1 routes at or above FL200 to indicate that all turns on the route between 30 and 90 degrees shall be made within the tolerance of a tangential arc between the straight leg segments defined with a radius of 22.5 NM.

d) Z - for RNP1 routes at or above FL190 to indicate that all turns on the route between 30 and 90 degrees shall be made within the tolerance of a tangential arc between the straight leg segments defined with a radius of 15 NM.
