(3) When the pressure altitude is above FL140:
(a) each flight crew member engaged in the operation of a Part 131 aircraft (performing duties) must use supplemental oxygen continuously; and
(b) supplemental oxygen must be available for the use of each flight crew member not performing duties.
(4) When the pressure altitude is above FL125, supplemental oxygen must be available for the use of each person on board a Part 131 aircraft.
(5) During the flight of a Part 131 aircraft that is conducting a balloon transport operation, when the pressure altitude is above 10 000 ft AMSL, a flight crew member must use supplemental oxygen continuously if the flight crew member considers that lack of oxygen may result in the impairment of the flight crew member’s faculties.
