Division 4—Operational equipment

11.08  Radiocommunication systems
 (1) An aeroplane, for a flight, must be fitted with 1 radiocommunication system that is capable of continuous communication on all frequencies necessary to meet reporting, broadcast and listening watch requirements under regulations 91.630, 91.635, 91.640, and 91.675 of CASR.
 (2) Subject to subsection (3), and without limiting subsection (1), for a flight in any class of airspace, an aeroplane must be fitted with at least 2 independent radiocommunication systems:
 (a) each capable, under normal operating conditions, of communicating with an appropriate ground station from any point on the route, including in the event of any diversion; and
 (b) each capable of receiving meteorological information at any time during the flight; and
 (c) at least one of which must have two-way voice communication capability; and
 (d) at least one of which must provide for communication on the aeronautical emergency frequency 121.5 MHz.
 (3) Despite subsection (2), an aeroplane for a VFR flight by day must be fitted with the following radiocommunication systems:
 (a) at least 1 VHF radiocommunication system;
 (b) if a VHF radiocommunication system would not allow for continuous communication with ATS at all stages of the flight — one of the following:
 (i) an additional radiocommunication system capable of continuous two‑way communications with ATS or the aeroplane's operator;
 (ii) an additional radiocommunication system capable of, after activation of the system by a crew member of the aeroplane, sending an automatic notification to the aeroplane's operator, or a person nominated by the operator, which:
                   (A) notifies the operator or person of an emergency situation during the flight; and
                   (B) includes information about the aeroplane's general location.
                  Note: The notification may involve a signal from the radiocommunication system being relayed via multiple communication technologies, for example, satellite relays or mobile phone networks.
 (4) If an additional radiocommunication system is fitted to the aeroplane under paragraph (3)(b), the system must only be used for communications with ATS, the aeroplane's operator or a person nominated by the operator, during the flight, when VHF communications with ATS are not available.

11.09  Navigation equipment
Note: For an aircraft entering oceanic airspace with RNP 2, RNP 4, or RNP 10, navigation specification capability, see subsections 11.03(1B) and (1C) of the Part 91 Manual of Standards in relation to long range navigation systems (LRNS) operability requirements. The term oceanic airspace is defined in subsection 11.01(2) of
