(4)
The letters Q, T, Y and Z identify RNAV routes which do not form part of the regional networks of Air Traffic Service routes.
b. SUPPLEMENTARY DESIGNATOR PREFIXES
(1)
K (KOPTER) is used to identify a low level route established for use primarily by helicopters.
(2)
U (UPPER) is used to indicate that the route (or portion thereof) is established in upper airspace.
(3)
S (SUPERSONIC) is used to indicate a route which is established exclusively for use by supersonic aircraft during acceleration, deceleration and while in supersonic flight.
c. DESIGNATOR SUFFIXES
(1)
The letter F to indicate that on the route or portion thereof advisory service only is provided.
(2)
The letter G to indicate that on the route or portion thereof flight information service only is provided.
(3)
For RNP 1 routes at and above FL200, the letter Y to indicate that all turns on the route between 30 and 90 degrees shall be made within the allowable RNP tolerance of a tangential arc between the straight leg segments defined with a radius of 22.5 NM (e.g. A123Y[1]).
(4)
For RNP 1 routes at and below FL190, the letter Z to indicate that all turns on the route between 30 and 90 degrees
shall be made within the allowable RNP tolerance of a tangential arc between the straight leg segments defined with a radius of 15 NM (e.g. G246Z[1]).
d. DESIGNATOR APPLICATIONS
ICAO recommends that Air Traffic Service route designators described above should consist of a basic alphanumeric designator, i.e., A411, which may be supplemented by one prefix as required, i.e., UA411, and/or as required by a single suffix, i.e., A411F.
e. DESIGNATOR PRONUNCIATIONS
With the exception of the descriptors "KOPTER", "UPPER" and "SUPERSONIC", the ICAO spelling (phonetic) alphabet will be used in voice communications when referring to the following Air Traffic Service route designators or suffixes:
A = ALFA N = NOVEMBER B = BRAVO P = PAPA D = DELTA Q = QUEBEC F = FOXTROT R = ROMEO G = GOLF T = TANGO H = HOTEL V = VICTOR J = JULIETT W = WHISKEY L = LIMA Y = YANKEE M = MIKE Z = ZULU
NOTE: Some countries continue to identify Air Traffic Service routes using color designations instead of the phonetic alphabet; i.e., A - Amber, B - Blue, G - Green, etc.

(1)
VFR - Whenever possible aircraft on transit flights above 3000 feet Above Ground Level are to be flown at appropriate Cruising Levels.
(2)
