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:

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.

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

NIGHT

−Same and, in addition, showing

steady landing lights (if carried).
