11.42  Oxygen masks — pressurised aeroplane
 (1) This section applies for a flight of a pressurised aeroplane.
 (2) An oxygen mask, for use by each pilot who is in a pilot seat, must:
 (a) be fitted to the aeroplane; and
 (b) be within immediate reach of a pilot who is in a pilot seat.
 (3) If, during the flight, the aeroplane will be flown above flight level 250, at least 1 pilot occupying a pilot seat must:
 (a) be wearing a sealed oxygen mask (securely worn) that:
 (i) is being supplied with supplemental oxygen; or
 (ii) automatically supplies supplemental oxygen when the cabin pressure altitude is at, or above, 14 000 ft; or
 (b) have access to a quick-donning mask that is supplied with supplemental oxygen when the mask is donned.
 (4) During the period when the aircraft is flown above FL 450 during the flight, at least 1 pilot occupying a pilot seat must be wearing one of the following that is being supplied with supplemental oxygen:
 (a) a sealed oxygen mask (securely worn); or
 (b) a quick-donning mask.

11.43  Oxygen dispensing units for passengers — pressurised aeroplane
 (1) This section prescribes the requirements relating to oxygen dispensing units required to be fitted to a pressurised aeroplane under section 11.40.
 (2) Subsection (3) applies if the aeroplane:
 (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 the 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 aeroplane's passenger compartments.
 (4) Subsection (5) applies if the aeroplane is not one mentioned in subsection (2).
 (5) For the passengers:
 (a) the oxygen dispensing units must be
