  • Oxygen minima: Carried PAX or number of seats ?

    Hi,
    I just need to have a confirmation of the following, since the EASA generally only refers to -passengers- in their documents.

    Supplemental O2 rules apply to CARRIED passengers.
    First aid (bottled) O2 rules apply to CARRIED passengers.
    O2 Masks rules apply to passengers SEATS.

    Am I correct, anything Im missing?
    Regards,
    Mathieu

    You are correct -

    Supplemental O2 rules apply to CARRIED passengers - YES, the NOTE at the bottom says Passenger numbers in Table 1 refer to passengers actually carried on board, including persons younger than 24 months.

    First aid (bottled) O2 rules apply to CARRIED passengers - YES,
    CAT.IDE.A.230 First-aid oxygen
    (a) Pressurised aeroplanes operated at pressure altitudes above 25 000 ft, in the case of operations for which a cabin crew member is required, shall be equipped with a supply of undiluted oxygen for passengers who, for physiological reasons, might require oxygen following a cabin depressurisation.
    (b) The oxygen supply referred to in (a) shall be sufficient for the remainder of the flight after cabin depressurisation when the cabin altitude exceeds 8 000 ft but does not exceed 15 000 ft, for at least 2 % of the passengers carried, but in no case for less than one person.
    (c) There shall be a sufficient number of dispensing units, but in no case less than two, with a means for cabin crew to use the supply.
    (d) The first-aid oxygen equipment shall be capable of generating a mass flow to each person.

    O2 Masks rules apply to passengers SEATS - YES
    CAT.IDE.A.235 Supplemental oxygen - pressurised aeroplanes
    (d) The total number of dispensing units and outlets referred to in (b)(3) and (c) shall exceed the number of seats by at least 10 %. The extra units shall be evenly distributed throughout the passenger compartment.
