2 PROCEDURES FOR THE INTERCEPTED AIRCRAFT
|
2.1. An aircraft which is intercepted by an intercepting aircraft shall immediately:
|
-
follow the instructions given by the intercepting aircraft, interpreting visual signals in accordance with specifications in the table below;
-
notify, if possible, the appropriate air traffic services unit;
-
attempt to establish radiocommunication with the intercepting aircraft or with the appropriate intercept control unit, by transmitting a general call on the emergency frequency 121.500 MHZ and the nature of the flight; and if no contact has been established and if practicable, repeating this call on the emergency frequency 243 MHZ;
-
if equipped with SSR transponder, select Mode A Code 7700, unless otherwise instructed by the appropriate air traffic services unit. If SSR transponder is equipped with Mode C, select Mode C and use it continuously unless otherwise instructed by appropriate air traffic services unit.
|
|
|
2.2. If radio contact is established during interception but communication in a common language is not possible, attempts shall be made to convey instructions, acknowledgement of instructions and essential information by using the phrases and pronunciations in the table below and transmitting each phrase twice.

|
DAY or NIGHT:
Rocking aircraft and flashing navigational lights at irregular intervals 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 the desired heading.
If intercepting aircraft is helicopter, flashing landing lights will be used additionally.
If intercepted aircraft is helicopter, intercepting aircraft will fly in the position slightly above, and to the right of helicopter.
Note 1: Meteorological conditions on terrain may require the intercepting aircraft to reverse the positions and direction of turn given above in Series 1.
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 the aircraft each time it passes the intercepted aircraft.

|
DAY or NIGHT:
Lowering landing gear (if fitted), showing steady landing lights and overflying runway in use or, if the intercepted aircraft is a helicopter, overflying the helicopter landing area. In case of helicopters, the intercepting helicopter makes a landing approach, coming to hover near the landing area.
|
LAND AT THIS AERODROME

|
DAY or NIGHT:
Lowering landing gear, (if fitted), showing steady landing lights and following the intercepting aircraft and, if, after overflying the runway in use or helicopter landing area, landing is considered safe, proceeding to land.

Raising landing gear (if fitted) and flashing landing lights while passing over runway in use or helicopter landing area at a height exceeding 300 M (1000 FT) but not exceeding 600 M (2000 FT) (in the case of a helicopter, at a height exceeding 50 M (170 FT) but not exceeding 100 M (330 FT)) above the aerodrome level, and continuing to circle runway in use or helicopter landing area. If unable to flash landing lights, flash any other lights available.

|
DAY or NIGHT:
If it is desired that the intercepted aircraft follow the intercepting aircraft to an alternate aerodrome, the intercepting aircraft raises its landing gear (if fitted) and uses the Series 1 signals prescribed for intercepting aircraft.
