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.
