Intercepting Signals
INTERCEPTING SIGNALS
Signals initiated by intercepting aircraft and responses by intercepted aircraft
(as set forth in ICAO Annex 2-Appendix 1, 2.1)
Series
INTERCEPTING Aircraft Signals
Meaning
INTERCEPTED Aircraft Responds
Meaning
1
DAY−Rocking wings from a position
slightly above and ahead of, and normally
to the left of, the intercepted aircraft and,
after acknowledgement, a slow level turn,
normally to the left, on to the desired
heading.
NIGHT-Same and, in addition, flashing
navigational lights at irregular intervals.
NOTE 1
−Meteorological conditions or
terrain may require the intercepting
aircraft to take up a position slightly above
and ahead of, and to the right of, the
intercepted aircraft and to make the
subsequent turn to the right.
NOTE 2
−If the intercepted aircraft is not
able to keep pace with the intercepting
aircraft, the latter is expected to fly a series
of race
−track patterns and to rock its wings
each time it passes the intercepted aircraft.
You have
been
intercepted.
Follow me.
AEROPLANES:
DAY−Rocking wings and following.
NIGHT−Same and, in addition, flashing
navigational lights at irregular intervals.
HELICOPTERS:
DAY or NIGHT−Rocking aircraft, flashing
navigational lights at irregular intervals and
following.
Understood,
will comply.
2
DAY or NIGHT−An abrupt break−away
maneuver from the intercepted aircraft
consisting of a climbing turn of 90 degrees
or more without crossing the line of flight
of the intercepted aircraft.
You may
proceed.
AEROPLANES:
DAY or NIGHT-Rocking wings.
HELICOPTERS:
DAY or NIGHT−Rocking aircraft.
Understood,
will comply.
3
DAY−Circling aerodrome, lowering land-
ing gear and overflying runway in direction
of landing or, if the intercepted aircraft is a
helicopter, overflying the helicopter land-
ing area.
NIGHT−Same and, in addition, showing
steady landing lights.
Land at this
aerodrome.
AEROPLANES:
DAY−Lowering landing gear, following
the intercepting aircraft and, if after
overflying the runway landing is consid-
ered safe, proceeding to land.
NIGHT−Same and, in addition, showing
steady landing lights (if carried).
HELICOPTERS:
DAY or NIGHT-Following the intercepting
aircraft and proceeding to land, showing a
steady landing light (if carried).
Understood,
will comply.
