                                                                                                                                                     (b) Without otherwise affecting paragraph (a):

                                                                                                                                                 (ii) the supply mentioned in subparagraph (i) must encompass the quantity of oxygen necessary for the aeroplane descending at a constant rate:
                                                                                                                                                        (A) from the aeroplane's maximum certified operating altitude; and
                                                                                                                                                        (B) to a pressure altitude of 15 000 ft in 10 minutes.
                                                                                                                                                    2. For any period when the cabin pressure altitude is above 14 000 ft but not above 15 000 ft, there must be supply for the entire period for at least 30% of the passengers.
                                                                                                                                                    3. For any period exceeding 30 minutes when the cabin pressure altitude is above 10 000 ft but not above 14 000 ft, there must be supply for the entire period for at least 10% of the persons mentioned in column 1.

11.41  Supplemental oxygen—unpressurised aeroplanes
 (1) An unpressurised aeroplane operated at a pressure altitude above 10 000 ft (a relevant aeroplane) must carry sufficient supplemental oxygen to meet the requirements set out in table 11.41.
 (2) A relevant aeroplane to which subsection (1) applies must be fitted with, or carry, supplemental oxygen equipment capable of storing and dispensing supplemental oxygen to crew members and passengers.
 (3) For a person mentioned in column 1 of an item of the table, supplemental oxygen must be made available in accordance with the supply requirements mentioned for the item in column 2.
 (4) Each flight crew member and assisting crew member must use the supplemental oxygen that is made available to each of them in accordance with the supply requirements mentioned in column 2 of item 1 of the table.
