COMMUNICATIONS FAILURE
GENERAL RULES
6.1.1 An aircraft operated as a controlled flight shall maintain continuous air-ground voice com-
munication watch on the appropriate communication channel of, and establish two-way communi-
cation as necessary with, the appropriate air traffic control unit, except as may be prescribed by
the appropriate ATS authority in respect of aircraft forming part of aerodrome traffic at a controlled
aerodrome. (Annex 2, 3.6.5.1)
NOTE 1: SELCAL or similar automatic signalling devices satisfy the requirement to maintain a lis-
tening watch.
NOTE 2: The requirement for an aircraft to maintain an air-ground voice communication watch
remains in affect after CPDLC has been established.
6.1.2 If a communication failure precludes compliance with 6.1.1, the aircraft shall comply with
the communication failure procedures in 6.2 below, and with such of the following procedures as
are appropriate. The aircraft shall attempt to establish communications with the appropriate air
traffic control unit using all other available means. In addition, the aircraft, when forming part of
the aerodrome traffic at a controlled aerodrome, shall keep a watch for such instructions as may
be issued by visual signals. (Annex 2, 3.6.5.2)
6.1.2.1 If in visual meteorological conditions, the aircraft shall:
a. continue to fly in visual meteorological conditions;
b. land at the nearest suitable aerodrome; and
c. report its arrival by the most expeditious means to the appropriate air traffic control unit.
(Annex 2, 3.6.5.2.1)
6.1.2.2 If in instrument meteorological conditions or when the pilot of an IFR flight considers it
inadvisable to complete the flight in accordance with 6.1.2.1 the aircraft shall:
a. unless otherwise prescribed on the basis of 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 air-
craft’s failure to report its position over a compulsory reporting point and thereafter adjust
level and speed in accordance with the filed flight plan;
