VFR/IFR communications

















Communication failure

Initial actions:

-check aircraft equipment;

-check appropriate ATC frequencies (previous frequency, emergency frequency 121.5, ...);

If attemps fail:

-squawk 7600;

-use blind transmission (use word "transmitting blind" and state message twice including position and intentions);

Procedure:

If in VMC

-continue to fly in visual meteorological conditions;
-land at the nearest suitable aerodrome;
-report arrival by the most expeditious means to the appropriate air traffic control unit;

If in IMC
or when conditions are such that it does not appear likely that the pilot will complete the flight in accordance with the prescribed VMC RCF procedures above:

-unless otherwise prescribed on the basis of a regional air navigation agreement, in airspace where radar is not used in the provision of air traffic control, maintain the last assigned speed and level, or minimum flight altitude if higher, for a period of 20 minutes following the aircraft’s failure to report its position over a compulsory reporting point and thereafter adjust level and speed in accordance with the filed flight plan;

-in airspace where radar is used in the provision of air traffic control, maintain the last assigned speed and level, or minimum flight altitude if higher, for a period of 7 minutes following:
i) the time the last assigned level or minimum flight altitude is reached; or
ii) the time the transponder is set to code 7600; or
iii) the aircraft’s failure to report its position over a compulsory reporting point;
whichever is later and thereafter adjust level and speed in accordance with the filed flight plan;

-when being vectored or having been directed by ATC to proceed offset using RNAV without a specified limit, proceed in the most direct manner possible to rejoin the current flight plan route no later than the next significant point, taking into consideration the applicable minimum flight altitude;


-proceed according to the current flight plan route to the appropriate designated navigation aid or fix serving the destination aerodrome and, when required, hold over this aid or fix until commencement of descent;

-commence descent at, or as close as possible to, the expected approach time last received and acknowledged; or, if no expected approach time has been received and acknowledged, at, or as close as possible to, the estimated time of arrival resulting from the current flight plan;

-complete a normal instrument approach procedure as specified for the designated navigation aid or fix;

-land, if possible, within 30 minutes after the estimated time of arrival or the last acknowledged expected approach time, whichever is later.
