Canadian Aviation Regulations — 604.50
604.50 No person shall conduct an instrument procedure using a GNSS receiver in an aircraft operated by a private operator unless (a) the private operator is authorized to do so under a special authorization; (b) every flight crew member has received the following training for which the validity period has not expired: (i) ground training in (A) the GNSS and its theory of operation, (B) the operation of the model of GNSS receiver that will be used, and (C) the actions to be taken in response to GNSS receiver warnings and messages, and (ii) in-flight training (A) in the operation of the model of GNSS receiver that will be used, (B) in the actions to be taken in response to GNSS receiver warnings and messages, (C) in the use of the GNSS receiver for instrument procedures and other associated duties for each crew position that the flight crew member will occupy, (D) provided (I) on board an aircraft, or (II) using a Level C or D full-flight simulator equipped with the same model of GNSS receiver as is installed in the private operator’s aircraft or with a model with a user interface comparable to the user interface of that GNSS receiver, and (E) provided by a pilot who has received training on the same model of GNSS receiver as is installed in the private operator’s aircraft or on a model with a user interface comparable to the user interface of that GNSS receiver; (c) every flight crew member has demonstrated to the private operator the ability to conduct an instrument approach using a GNSS receiver in accordance with this section; (d) the coverage area of the GNSS receiver database is compatible with the area of operation in which the aircraft will be operated; (e) the private operator has established procedures to ensure that (i) the GNSS receiver database is updated so that it remains current, (ii) flight crew members who identify GNSS receiver database errors communicate those errors to the private operator, and (iii) the GNSS receiver database errors identified are communicated to the private operator’s other personnel and to the GNSS receiver database provider; (f) if the aircraft is designed to be operated by one flight crew member, the GNSS course deviation and distance displays are located at the pilot station normally occupied by the pilot-in-command and within the primary field of vision of the flight crew member who occupies the pilot station; (g) if the aircraft is designed to be operated by two flight crew members, the GNSS course deviation and distance displays are located at each pilot station and within the primary field of vision of the flight crew member who occupies the pilot station; (h) if the aircraft is designed to be operated by one flight crew member, but can be operated by two flight crew members, (i) the control display unit that is linked to the GNSS receiver is centrally located in relation to the two pilot stations and provides navigation information that is visible to the pilot not flying, or (ii) the GNSS course deviation and distance displays are located at each pilot station and within the primary field of vision of the flight crew members who occupy those pilot stations; and (i) the private operator has established GNSS approach procedures in order to prevent confusion between GNSS distance information and distance measuring equipment (DME) information.
