1.13.1  General

The following procedures are intended as guidance for use by aircraft when unlawful interference occurs.

1.13.2  Procedures An aircraft which is being subjected to unlawful interference shall endeavour to set the transponder to Code 7500 and notify the appropriate ATS unit of, any significant circumstances associated therewith and any deviation from the current flight plan necessitated by the circumstances, in order to enable the ATS unit to give priority to the aircraft and to minimise conflict with other aircraft. If an aircraft is subjected to unlawful interference, the pilot-in-command shall attempt to land as soon as practicable at the nearest suitable aerodrome or at a dedicated aerodrome assigned by the competent authority unless considerations aboard the aircraft dictate otherwise. If the pilot-in-command cannot proceed to an aerodrome in accordance with para. ENR, he should continue flying on the assigned track and at the assigned cruising level at least until able to notify an ATS unit or within radar coverage. When an aircraft subjected to an act of unlawful interference must depart from its assigned track or its assigned cruising level without being able to make radiotelephony contact with ATS, the pilot-in-command shall, whenever possible attempt to broadcast warnings on the VHF emergency frequency and other appropriate frequencies, unless considerations aboard the aircraft dictate otherwise and when it is advantageous to do so or circumstances permit other equipment (such as on-board transponders or data links) should also be used and proceed at a level which differs from the cruising levels normally used for IFR flights in the area by 500 ft (150 m) for flights at FL 410 below or by 1 000 ft (300 m) for flights above FL 410.
