Subchapter G - Flight Crew Interface and Other Information

523.2600 Flight Crew Interface

  • (a) The pilot compartment, its equipment, and its arrangement to include pilot view, must allow each pilot to perform his or her duties, including taxi, take-off, climb, cruise, descent, approach, landing, and perform any manoeuvres within the operating envelope of the aeroplane, without excessive concentration, skill, alertness, or fatigue.
  • (b) The applicant must install flight, navigation, surveillance, and powerplant controls and displays so flight crew members can monitor and perform defined tasks associated with the intended functions of systems and equipment. The system and equipment design must minimise flight crew errors, which could result in additional hazards.
  • (c) For level 4 aeroplanes, the flight crew interface design must allow for continued safe flight and landing after the loss of vision through any one of the windshield panels.

(effective 2021/09/21)

523.2605 Installation and Operation

  • (a) Each item of installed equipment related to the flight crew interface must be labelled, if applicable, as to its identification, function, or operating limitations, or any combination of these factors.
  • (b) There must be a discernible means of providing system operating parameters required to operate the aeroplane, including warnings, cautions, and normal indications to the responsible crew member.
  • (c) Information concerning an unsafe system operating condition must be provided in a timely manner to the crew member responsible for taking corrective action. The information must be clear enough to avoid likely crew member errors.

(effective 2021/09/21)

523.2610 Instrument Markings, Control Markings, and Placards

  • (a) Each aeroplane must display in a conspicuous manner any placard and instrument marking necessary for operation.
  • (b) The design must clearly indicate the function of each cockpit control, other than primary flight controls.
  • (c) The applicant must include instrument marking and placard information in the Aeroplane Flight Manual.

(effective 2021/09/21)

523.2615 Flight, Navigation, and Powerplant Instruments

  • (a) Installed systems must provide the flight crew member who sets or monitors parameters for the flight, navigation, and powerplant, the information necessary to do so during each phase of flight. This information must:
    • (1) Be presented in a manner that the crew member can monitor the parameter and determine trends, as needed, to operate the aeroplane; and
    • (2) Include limitations, unless the limitation cannot be exceeded in all intended operations.
  • (b) Indication systems that integrate the display of flight or powerplant parameters to operate the aeroplane or are required by the applicable operating rules must:
    • (1) Not inhibit the primary display of flight or powerplant parameters needed by any flight crew member in any normal mode of operation; and
    • (2) In combination with other systems, be designed and installed so information essential for continued safe flight and landing will be available to the flight crew in a timely manner after any single failure or probable combination of failures.

(effective 2021/09/21)

523.2620 Aeroplane Flight Manual

The applicant must provide an Aeroplane Flight Manual that must be delivered with each aeroplane.

  • (a) The Aeroplane Flight Manual must contain the following information:
    • (1) Aeroplane operating limitations;
    • (2) Aeroplane operating procedures;
    • (3) Performance information;
    • (4) Loading information; and
    • (5) Other information that is necessary for safe operation because of design, operating, or handling characteristics.
  • (b) The following sections of the Aeroplane Flight Manual must be approved by Transport Canada in a manner specified by the Minister:
    • (1) For low-speed, level 1 and 2 aeroplanes, those portions of the Aeroplane Flight Manual containing the information specified in paragraph (a)(1) of this section; and
    • (2) For high-speed level 1 and 2 aeroplanes and all level 3 and 4 aeroplanes, those portions of the Aeroplane Flight Manual containing the information specified in paragraphs (a)(1) thru (a)(4) of this section.
