the CVR within a combination recorder, fitted to a rotorcraft under this Division, must record continuously during the same periods as an FDR and CVR are required to operate under subsections (1) and (2).
 (4) If:
 (a) there is no APU, or other alternative power source, for the rotorcraft; and
 (b) it is reasonably necessary to preserve the rotorcraft's primary power source in order to start the rotorcraft's engines; and
 (c) the FDR is operated continuously during the period beginning just before the engines are started for take-off and ending when the final pilot checklist is completed at the end of the flight;
then, a CVR, fitted to a rotorcraft under this Division, must record continuously during the period:
 (d) beginning after the engines are started for the flight; and
 (e) ending when the final pilot checklist is completed at the end of the flight.
 (5) An FDR or combination recorder, fitted to a rotorcraft under this Division, must not be operated during the maintenance of the rotorcraft or an aeronautical product fitted to the rotorcraft, except if the maintenance is to the recorder or an engine.
 (6) For subsection (5), an APU fitted to the rotorcraft is not an engine, unless it is capable of propelling the rotorcraft.
 (7) This section applies subject to section 11.28.

11.28  Flight with an inoperative FDR, CVR or combination recorder
  An FDR, CVR or combination recorder, fitted to a rotorcraft under this Division, may be inoperative at the beginning of a flight only if:
 (a) the flight begins from a departure aerodrome with no facility for the recorder to be repaired or replaced; and
 (b) the rotorcraft is only required to be fitted with 1 CVR or 1 FDR — the inoperative recorder has not been inoperative for more than 21 days; and
 (c) the rotorcraft is required to be fitted with 1 CVR and 1 FDR:
 (i) the inoperative recorder has not been inoperative for more than 21 days; and
 (ii) the other recorder is operative; and
 (d) the rotorcraft is fitted with 1 combination recorder — the inoperative recorder must not have been inoperative for more than 3 days; and
 (e) the rotorcraft is fitted with more than 1 combination recorder:
 (i) an inoperative combination recorder has not been inoperative for more than 21 days; and
 (ii) at least one combination recorder is operative.

Division 8—Rotorcraft interior communication systems

11.30  Flight crew intercommunication system
 (1) Subject to subsections (2) and (3), a rotorcraft must be fitted with a flight crew intercommunication system that consists of 1 headset, and 1 microphone that is not of the hand-held type, for each pilot for the flight.
 (2) A rotorcraft
