| valign="top" | ''Day or night.'' Rocking aircraft and flashing navigational lights at irregular intervals (landing lights for helicopters), from slightly ahead and above and normally to the left side of the intercepted aircraft (normally to the right side of intercepted helicopters). | |||
After acknowledgement a slow level turn normally to the left (normally to the right of intercepted helicopters) to the desired heading. | |||
''Note 1: Terrain or weather may require series one manoeuvres to be done in the opposite direction.'' | |||
''Note 2: If the intercepted aircraft is unable to keep pace with the intercepted aircraft, the intercepting aircraft should do race track patterns around the intercepted aircraft, rocking the aircraft every pass.'' | |||
| valign="top" | You have been intercepted. Follow me. | |||

| valign="top" rowspan="2" | ''Day or night.'' Raising landing gear, flashing the landing lights and passing over the runway in use at an altitude between 1 000 and 2 000 ft and continuously to circle the runway in use (if the intercepted aircraft is a helicopter flying over the landing area at an altitude between 170 ft and 330 ft and continuously circling the landing area). | |||
If unable to flash landing lights flash any other lights available. | |||
| valign="top" rowspan="2" | Aerodrome you have designated is inadequate. | |||
| valign="top" | ''Day or night.'' If it is desired to land the aircraft at an alternate aerodrome, the intercepting aircraft raises its landing gear and proceeds with series 1 signals for intercepting aircraft. | |||
| valign="top" | Understood. Follow me. | |||
|- | |||
| valign="top" | ''Day or night.'' If it is decided to release the intercepted aircraft, the intercepting aircraft raises its landing gear and proceeds with series 2 signals for intercepting aircraft. | |||
