necessary.
For flights operating predominantly in a north-south
direction, define tracks by reference to significant
points formed by the intersection of whole degrees
of longitude with specified parallels of latitude
which are spaced at 5 degrees.
INSERT DCT between successive points unless both points
are defined by geographical coordinates or by
bearing and distance.
USE ONLY the conventions in (1) to (5) below and
SEPARATE each sub-item by a space.
The coded designator assigned to the route or route segment
including, where appropriate, the coded designator assigned to
the standard departure or arrival route (e.g. BCN1, Bl, R14,
UB10, KODAP2A).
Note.— Provisions for the application of route
designators are contained in Annex 11, Appendix 1, whilst
guidance material on the application of an RNP type to a
specific route segment(s), route(s) or area is contained in
the Manual on Required Navigation Performance (RNP)
(Doc 9613).
The coded designator (2 to 5 characters) assigned to the point
(e.g. LN, MAY, HADDY), or,
(c) Route (including changes of speed,
(c) level and/or flight rules)
(1) ATS route (2 to 7 characters)
(2) Significant point (2 to 11 characters)
Appendix 2 A2-7

if no coded designator has been assigned, one of the following
ways:
— Degrees only (7 characters):
2 figures describing latitude in degrees, followed by “N”
(North) or “S” (South), followed by 3 figures describing
longitude in degrees, followed by “E” (East) or “W”
(West). Make up the correct number of figures, where
necessary, by insertion of zeros, e.g. 46N078W.
— Degrees and minutes (11 characters):
4 figures describing latitude in degrees and tens and
units of minutes followed by “N” (North) or “S”
(South), followed by 5 figures describing longitude in
degrees and tens and units of minutes, followed by “E”
(East) or “W” (West). Make up the correct number of
figures, where necessary, by insertion of zeros, e.g.
4620N07805W.
— Bearing and distance from a navigation aid:
The identification of the navigation aid (normally a
VOR), in the form of 2 or 3 characters, THEN the
bearing from the aid in the form of 3 figures giving
degrees magnetic, THEN the distance from the aid in the
form of 3 figures expressing nautical miles. Make up the
correct number of figures, where necessary, by insertion
of zeros — e.g. a point 180° magnetic at a distance of
40 nautical miles from VOR “DUB” should be
expressed as DUB180040.
The point at which a change of speed (5% TAS or 0.01 Mach
or more) or a change of level is planned, expressed exactly as
in (2) above, followed by an oblique stroke and both the
cruising speed and the cruising level, expressed exactly as in
(a) and (b) above, without a space between them, even when
only one of these quantities will be changed.
Examples: LN/N0284A045
MAY/N0305Fl80
HADDY/N0420F330
4602N07805W/N0500F350
46N078W/M082F330
DUB180040/N0350M0840
The point at which the change of flight rules is planned,
expressed exactly as in (2) or (3) above as appropriate,
followed by a space and one of the following:
VFR if from IFR to VFR
IFR if from VFR to IFR
Examples: LN VFR
LN/N0284A050 IFR
The letter C followed by an oblique stroke; THEN the point at
which cruise climb is planned to start, expressed exactly as in
(2) above, followed by an oblique stroke; THEN the speed to
be maintained during cruise climb, expressed exactly as in (a)
above, followed by the two levels defining the layer to be
occupied during cruise climb, each level expressed exactly as
in (b) above, or the level above which cruise climb is planned
followed by the letters PLUS, without a space between them.
Examples: C/48N050W/M082F290F350
C/48N050W/M082F290PLUS
C/52N050W/M220F580F620.
INSERT the ICAO four-letter location indicator of the
destination aerodrome followed, without a space, by
the total estimated elapsed time,
OR, if no location indicator has been assigned,
INSERT ZZZZ followed, without a space, by the total
estimated elapsed time, and SPECIFY in Item 18
the name of the aerodrome, preceded by DEST/ .
(3)
Change of speed or level
(maximum 21 characters)
(4)
Change of flight rules
(maximum 3 characters)
(5) Cruise climb (maximum 28 characters)
