  "text": "(1)immediately follow the instructions given by the intercepting aircraft, interpreting and responding to visual signals in accordance with the specifications in Tables S11-1 and S11-2;\n(2)notify, if possible, the appropriate air traffic services unit;\n(3)attempt to establish radio-communication with the 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; and if no contact has been established and if practicable, repeating this call on the emergency frequency 243 MHz;\n(4)if equipped with SSR transponder, select Mode A, Code 7700, unless otherwise instructed by the appropriate air traffic services unit;\n(5)if equipped with ADS-B or ADS-C, select the appropriate emergency functionality, if available, unless otherwise instructed by the appropriate air traffic services unit.\nTable S11-1\nSignals initiated by intercepting aircraft and responses by intercepted aircraft\nSeries\nINTERCEPTING Aircraft Signals\nMeaning\nINTERCEPTED Aircraft Responds\nMeaning\n1\nDAY 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.\nNote 1\nMeteorological conditions or terrain may require the intercepting aircraft to reverse the positions and direction of turn given above in Series 1.\nNote 2\nIf 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.\nYou have been intercepted. Follow me.\nDAY or NIGHT — Rocking aircraft, flashing navigational lights at irregular intervals and following.\nUnderstood, will comply.\n2\nDAY 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.\nYou may proceed.\nDAY or NIGHT — Rocking the aircraft.\nUnderstood, will comply.\n3\nDAY 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 the case of helicopters, the intercepting helicopter makes a landing approach, coming to hover near to the landing area.\nLand at this aerodrome.\nDAY 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.\nUnderstood, will comply.\nTable S11-2\nSignals initiated by intercepted aircraft and responses by intercepting aircraft\nSeries\nINTERCEPTED Aircraft Signals\nMeaning\nINTERCEPTING Aircraft Responds\nMeaning\n4\nDAY 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.\nAerodrome you have designated is inadequate.\nDAY 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.\nIf it is decided to release the intercepted aircraft, the intercepting aircraft uses the Series 2 signals prescribed for intercepting aircraft.\nUnderstood, follow me.\nUnderstood, you may proceed.\n5\nDAY or NIGHT — Regular switching on and off of all available lights but in such a manner as to be distinct from flashing lights.\nCannot comply.\nDAY or NIGHT — Use Series 2 signals prescribed for intercepting aircraft.\nUnderstood.\n6\nDAY or NIGHT — Irregular flashing of all available lights.\nIn distress.\nDAY or NIGHT — Use Series 2 signals prescribed for intercepting aircraft.\nUnderstood.",
