in flight or on the ground.
 (3) The system, other than handsets, headsets, microphones, selector switches and signalling devices, must operate independently of:
 (a) the flight crew intercommunication system required by section 11.30; and
 (b) the crew interphone system required by section 11.31, if any.
 (4) The system must be readily accessible for use by each flight crew member from the flight crew member's seat in the flight crew compartment.
 (5) At each emergency exit with an adjacent cabin crew, or air crew member, seat on the same level as a passenger compartment (a relevant location), there must be a handset or microphone operable by a cabin crew member, or air crew member, while seated.
 (6) The system must be operable within 10 seconds of activation by a cabin crew member, or air crew member, at each relevant location.
 (7) Announcements made using the system must be audible at all passenger seats.

Division 9—Oxygen equipment and oxygen supplies

11.33  Definitions for Division 9
  In this Division:
assisting crew member means a crew member who assists flight crew members with the fight crew member's duties.
quick-donning mask means an oxygen mask that:
 (a) is for a flight crew member's personal use; and
 (b) within 5 seconds of it being deployed and ready for use, the flight crew member can, with 1 hand, place over the flight crew member's face, secure and seal.
standard temperature and pressure means 0 degrees Celsius at a pressure of 760 mm Hg.
STPD means standard temperature and pressure dry.

11.34  Supplemental oxygen — pressurised rotorcraft
 (1) A pressurised rotorcraft operated at a pressure altitude above 10 000 ft (a relevant rotorcraft) must be fitted with or carry supplemental oxygen equipment capable of storing and dispensing supplemental oxygen to crew members and passengers.
 (2) Subject to subsection (3), a relevant rotorcraft must carry sufficient supplemental oxygen to meet the requirements set out in Table 11.34(2).
 (3) For a flight of a pressurised rotorcraft that:
 (a) during the flight will be flown above 13 000 ft, but not above FL250; and
 (b) at all points along the route of the flight, the rotorcraft will be able to:
 (i) descend safely to 13 000 ft within 4 minutes; and
 (ii) complete the planned flight, or land at an aerodrome that is suitable for the rotorcraft to land at;

  the amount of supplemental oxygen required for the passengers, if any, is either:

 (c) that which is sufficient to meet the passenger requirements set out in Table11.34(2); or
 (d) an amount of supplemental oxygen enough to supply 10% of the passengers for the flight for the period while the rotorcraft's cabin pressure altitude exceeds 10 000 ft and does not exceed
