All aircraft flying in air space above the Indian Territory, including territorial waters adjacent thereto are required to follow, the established ATS routes as promulgated by NOTAM or Aeronautical Information Publication or any other route over which the flight is specifically permitted. Pilots are cautioned not to fly in the air space over Indian Territory within 15NM of the border of India except when following an ATS or specifically permitted route or when operating to or from any aerodrome situated within 15NM of border of India.
|

|
2.
|
Occasions may arise when due to circumstances beyond the control of the Pilot-in-command a deviation from the ATS/specifically permitted route may have been/to be made. When such a situation arises, the Pilot-in-command of the aircraft shall inform the appropriate Air Traffic Control Centre (ATCC) by the quickest means available of the following:
|
|
i) Present position-direction and flight level of the aircraft.
|
|
ii) Position, flight level and time at which the deviation from the route was/is expected to be made.
|
|
iii) Direction and distance the aircraft has deviated/is likely to deviate from the route.
|
|
iv) Position, time and flight level of entry likely reentry into the route.
|
|
|
3.
|
If an aircraft penetrates into/operates within an ADIZ without Air Defence Clearance, strays into a restricted area/prohibited area/danger area or fails to inform the Air Traffic Control Centre about its deviation/intended deviation from the route, it will be liable to interception by fighter aircraft.
|
|
|
4.
|
The interception will be carried out with every respect to the safety of the intercepted aircraft and in a manner which will ensure that the occupants are not disturbed. An aircraft which is intercepted by another aircraft shall immediately
|
|
i) Attempt to establish radio telecommunication with intercepting aircraft or with the appropriate intercept control unit, by making a general call on the emergency frequency 121.5 MHZ giving the identity of the intercepted aircraft and the nature of the flight.flight and if no contact has been established and if practicable, repeating this call on the emergency frequency 243 MHz.
|
|
ii) Follow instructions given by the Intercepting aircraft, interpreting and responding to visual signals in accordance with the specifications given in para 9. These visual signals will normally be used on instructions from responsible Air Defence Authority when all other means of communication with the aircraft fail.
|
|
iii) Notify, if possible, the appropriate air traffic service unit.
|
|
iv) If equipped with SSR transponder select Mode A, Code7700, unless otherwise instructed by the appropriate Air Traffic Services Unit.
|
|
v) If equipped with ADS-B or ADS-C, select the appropriate emergency functionality if available, unless otherwise instructed by the appropriate Air Traffic Service unit.
|
|
|
5.
|
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 as mentioned in para 8 and transmitting each phrase twice.
|
|
|
6.
|
If any instructions received by radio from any sources conflict with those given by the intercepting aircraft by visual/radio signals, intercepted aircraft shall request immediate clarification while continuing to comply with the visual/radio instructions given by the intercepting aircraft.
|
|
|
7.
|
The possibility of interception and recourse to the visual signals in para 9 would not normally arise if there is strict compliance with requirements of Air Defense Clearance, avoiding restricted, prohibited/ danger areas and no deviation is made from flight plan route and a listening watch is being maintained on appropriate ATS frequency. Pilots are warned, however, that should the occasion arise they must comply with the visual signals/radio instructions given by the intercepting aircraft.

Meaning

1
|
DAY or NIGHT -- Rocking aircraft and flashing navigational lights at irregular intervals (and landing lights in the case of a helicopter) from a position slightly above and ahead of, and normally to the left of, the intercepted aircraft (or to the right if the intercepted aircraft is a helicopter) and, after acknowledgement, a slow level turn, normally to the left (or to the right in the case of a helicopter) on the desired heading.
|
You have been intercepted follow-me
|
DAY or NIGHT -
Rocking aircraft, flashing navigational lights at irregular intervals and following.
|
Understood, will comply
|
|
|
|
|
Note 1.-- Meteorological conditions or terrain may require the intercepting aircraft to reverse the positions and direction of turn given above in Series 1.
|
Note.-- Additional action required to be taken by intercepted aircraft is prescribed in Annex 2, Chapter 3, 3.8.
|
|
|
|
|
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 racetrack patterns and to rock the aircraft each time it passes the intercepted aircraft
|
|
|
2
|
DAY or NIGHT -- An abrupt breakaway manoeuvre 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
|
DAY or NIGHT - Rocking the aircraft.
|
Understood, will comply
|
|
3
|
DAY or NIGHT-Lowering landing gear (if fitted), showing steady landing lights and over-flying runway in use or, if the intercepted aircraft is a helicopter, over-flying the helicopter landing area. In the case of helicopters, the intercepting helicopter makes a landing approach, coming to hover near to 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.
|
Understood, will comply

DAY or NIGHT -- 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 (1 000 ft) but not exceeding 600 m (2 000 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.
|
Aerodrome your have designated is inadequate
|
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.
If it is decided to release the intercepted aircraft, the intercepting aircraft uses the series 2 signals prescribed for intercepting aircraft.
