Annex 11 Appendix 3
2. Composition of designators
2.1 Plain language designator
2.1.1 The plain language designator of a standard departure
or arrival route shall consist of:
a) a basic indicator; followed by
b) a validity indicator; followed by
c) a route indicator, where required; followed by
d) the word “departure” or “arrival”; followed by
e) the word “visual”, if the route has been established for
use by aircraft operating in accordance with the visual
flight rules (VFR).
2.1.2 The basic indicator shall be the name or name-code
of the significant point where a standard departure route
terminates or a standard arrival route begins.
2.1.3 The validity indicator shall be a number from 1
to 9.
2.1.4 The route indicator shall be one letter of the
alphabet. The letters “I” and “O” shall not be used.

3. Assignment of designators
3.1 Each route shall be assigned a separate designator.
3.2 To distinguish between two or more routes which
relate to the same significant point (and therefore are assigned
the same basic indicator), a separate route indicator as
described in 2.1.4 shall be assigned to each route.
4. Assignment of validity indicators
4.1 A validity indicator shall be assigned to each route to
identify the route which is currently in effect.
4.2 The first validity indicator to be assigned shall be the
number “1”.
4.3 Whenever a route is amended, a new validity
indicator, consisting of the next higher number, shall be
assigned. The number “9” shall be followed by the
number “1”.
My
bold. The UK uses the point at which the STAR
ends. I thought we were alone, but interesting to learn that Oz is similarly determined to confuse.
