605.31 (1) No person shall operate
an unpressurized aircraft unless it is equipped with sufficient oxygen
dispensing units and oxygen supply to comply with the requirements set
out in the table to this subsection.

Persons for Whom Oxygen Supply Must Be
Available |
Period of Flight and
Cabin-Pressure-Altitude |
| 1. |
All crew members and 10 per cent of passengers
and, in any case, no less than one passenger |
Entire period of flight exceeding 30 minutes at
cabin-pressure-altitudes above 10,000 feet ASL but not exceeding
13,000 feet ASL |
| 2. |
All persons on board the aircraft |
(a) Entire period of flight at
cabin-pressure-altitudes above 13,000 feet ASL
(b) For aircraft operated in an air transport
service under the conditions referred to in paragraph (a), a
period of flight of not less than one hour. |
(2) No person shall operate a pressurized aircraft
unless it is equipped with sufficient oxygen dispensing units and oxygen
supply to provide, in the event of cabin pressurization failure at the
most critical point during the flight, sufficient oxygen to continue the
flight to an aerodrome suitable for landing while complying with the
requirements of the table to this subsection.

Period of Flight and
Cabin-Pressure-Altitude |
| 1. |
All crew members and 10 per cent of passengers
and, in any case, no less than one passenger |
(a) Entire period of flight exceeding
30 minutes at cabin-pressure-altitudes above 10,000 feet ASL but
not exceeding 13,000 feet ASL
(b) Entire period of flight at
cabin-pressure-altitudes above 13,000 feet ASL
(c) For aircraft operated in an air transport
service under the conditions referred to in paragraph (a) or
(b), a period of flight of not less than
(i) 30 minutes (Note 2), and
(ii) for flight crew members, two hours for aircraft the type
certificate of which authorizes flight at altitudes exceeding
FL 250 (Note 3) |
| 2. |
All passengers |
(a) Entire period of flight at
cabin-pressure-altitudes exceeding 13,000 feet ASL
(b) For aircraft operated in an air transport
service under the conditions referred to in paragraph (a), a
period of flight of not less than 10 minutes |
Note 1: In determining the available supply, the
cabin pressure altitude descent profile for the routes concerned must be
taken into account.
Note 2: The minimum supply is that quantity of
oxygen necessary for a constant rate of descent from the aircraft's
maximum operating altitude authorized in the type certificate to 10,000
feet ASL in 10 minutes, followed by 20 minutes at 10,000 feet ASL.
Note 3: The minimum supply is that quantity of
oxygen necessary for a constant rate of descent from the aircraft's
maximum operating altitude authorized in the type certificate to 10,000
feet ASL in 10 minutes, followed by 110 minutes at 10,000 feet ASL. |
