11.40  Supplemental oxygen — pressurised aeroplanes
 (1) A pressurised aeroplane operated at a pressure altitude above 10 000 ft (a relevant aeroplane) 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 aeroplane must carry sufficient supplemental oxygen to meet the requirements set out in Table 11.40(2).
 (3) For a flight of a relevant aeroplane 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, 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 aeroplane to land at;

  then 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 Table 11.40(2); or
 (d) an amount of supplemental oxygen enough to supply 10% of the passengers for the flight for the period while the aeroplane's cabin pressure altitude exceeds 10 000 ft and does not exceed 13 000 ft.
 (4) For a person mentioned in column 1 of an item in Table 11.40(2), supplemental oxygen must be made available through an oxygen dispensing unit in accordance with the supply requirements mentioned for the item in column 2.
 (5) Each flight crew member, and any assisting crew member, must use an oxygen mask that is supplying supplemental oxygen while the aeroplane's cabin altitude exceeds 10 000 ft.
