11.36  Oxygen mask — pressurised rotorcraft
 (1) This section applies for a flight of a pressurised rotorcraft.
 (2) An oxygen mask, for use by each pilot who is in a pilot seat, must:
 (a) be fitted to the rotorcraft; and
 (b) be within immediate reach of a pilot who is in a pilot seat.
 (3) If, during the flight, the rotorcraft will be flown above flight level 250, the following requirements must be met:
 (a) the oxygen mask fitted to the rotorcraft under subsection (1) must be a quick-donning mask;
 (b) while the rotorcraft is flown above flight level 250, at least 1 pilot who is in a pilot seat must wear and use a quick-donning mask.

11.37  Oxygen dispensing units for passengers in a pressurised rotorcraft
 (1) This section prescribes the requirements relating to oxygen dispensing units required to be fitted to a pressurised rotorcraft under section 11.34.
 (2) Subsection (3) applies if the rotorcraft:
 (a) is of a type that was first issued with a certificate of airworthiness, or an authorisation (however described) equivalent to a certificate of airworthiness issued by the NAA of a Contracting State, on, or after, 9 November 1998; and
 (b) either:
 (i) is flown at or above FL 250 at any time during the flight; or
 (ii) if flown below FL 250 — cannot safely descend from its flight level to a cabin pressure altitude of less than 13 000 ft within a period of 4 minutes in the event of a cabin depressurisation.
 (3) For passengers:
 (a) the oxygen dispensing units must be automatically deployable; and
 (b) the units must be immediately available to each passenger on the flight, wherever seated; and
 (c) the number of dispensing units must exceed the number of passenger seats by 10% (the additional units); and
 (d) the additional units must be evenly distributed throughout the rotorcraft's passenger compartments.
 (4) Subsection (5) applies if the rotorcraft is not one mentioned in subsection (2).
 (5) For the passengers:
 (a) the oxygen dispensing units must be immediately available to each passenger on the flight, wherever seated; and
 (b) the number of dispensing units must exceed the number of passenger seats by 10% (the additional units); and
 (c) the additional units must be evenly distributed throughout the rotorcraft's passenger compartments.

11.38  Protective breathing equipment — flight crew members
 (1) When a pressurised rotorcraft begins a flight, it must be carrying
