TBL 5-6-1 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 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. You have been intercepted. Follow me. 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. INTERCEPTED Aircraft Responds AEROPLANES: DAY-Rocking wings and following. Meaning Understood, will comply. 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.

DAY-Circling aerodrome, lowering land- Land at this ing gear and overflying runway in direction aerodrome. of landing or, if the intercepted aircraft is a helicopter, overflying the helicopter landing area. AEROPLANES: Understood, DAY-Lowering landing gear, following will comply. the intercepting aircraft and, if after overflying the runway landing is considered safe, proceeding to land. NIGHT-Same and, in addition, showing steady landing lights. NIGHT-Same and, in addition, showing steady landing lights (if carried). HELICOPTERS: DAY or NIGHT-Rocking aircraft.
