and the aircraft is unable to notify an ATS unit of this fact. |
| |
| |
| 2. | PROCEDURES |

| Unless
considerations aboard the aircraft dictate otherwise, the pilotincommand should attempt to
continue flying on the assigned track and at the assigned cruising level at least until
notification to an ATS unit is possible or the aircraft is within radar coverage |

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 pilotincommand should, whenever possible |
| a) | attempt to
broadcast warnings on the VHF emergency frequency and other appropriate frequencies,
unless considerations aboard the aircraft dictate otherwise. Other equipment such as
onboard transponders, data links, etc., should also be used when it is advantageous to do
so and circumstances permit. The transponder shall be set to mode A/3 code 7500;
and |
| |

accordance with applicable special procedures for inflight contingencies, where such
procedures have been established and promulgated in DOC 7030 Regional Supplementary
Procedures; or |
| |
| c) | if no
applicable regional procedures have been established, proceed at a level which differs
from the cruising levels normally used for IFR flight in the area by 300 m (1000 ft) if
above FL 290 or by 150 m (500 ft) if below FL 290. |
