B— At FL 250 and above, each pilot shall have an approved quick-donning oxygen mask. C— At FL 250 and above, the pilot at the controls must have an approved oxygen mask any time the other pilot is away from the duty station.

The two pilot stations of a pressurized aircraft are equipped with approved quick-donning oxygen masks. What is the maximum altitude authorized if one pilot is not wearing an oxygen mask and breathing oxygen?. A— 41,000 feet MSL. B— 35,000 feet MSL. C— 25,000 feet MSL.

At altitudes above 10,000 feet through 12,000 feet MSL, each pilot of an unpressurized airplane must use supplemental oxygen for that part of the flight that is of a duration of more than. A— 20 minutes. B— 30 minutes. C— 45 minutes.

A pressurized airplane being operated at FL 330 can descend safely to 15,000 feet MSL in 3.5 minutes. What oxygen supply must be carried for all occupants other than the pilots?. A— 60 minutes. B— 45 minutes. C— 30 minutes.

At what altitude, in an unpressurized airplane, must all passengers be supplied oxygen?. A— Above 12,000 feet MSL. B— Above 14,000 feet MSL. C— Above 15,000 feet MSL.

Between what altitudes must oxygen be available to at least 10 percent of the occupants, in an unpres-surized airplane, other than the pilots?. A— Above 12,000 feet through 16,000 feet MSL, for any time period. B— Above 10,000 feet through 15,000 feet MSL, if flight at those altitudes is of more than a 30-minute duration. C— 10,000 feet to 15,000 feet MSL, if flight at those altitudes is of more than a 30-minute duration.

The oxygen requirements for occupants of a pressurized airplane operated at altitudes above FL 250 is dependent upon the airplane’s ability to descend safely to an altitude of. A— 10,000 feet MSL in 4 minutes. B— 12,000 feet MSL at a minimum rate of 2,500 ft/min. C— 15,000 feet MSL in 4 minutes.

Above which altitude/flight level must at least one of the two pilots, at the controls of a pressurized aircraft (with quick-donning masks) wear a secured and sealed oxygen mask?. A— FL 300. B— FL 350. C— FL 250.

. Which is a pilot requirement for oxygen?. A— Each pilot of a pressurized aircraft operating at FL 180 and above shall have an approved quick-donning type oxygen mask. B— On pressurized aircraft requiring a flightcrew of two pilots, both shall continuously wear oxygen masks whenever the cabin pressure altitude exceeds 12,000 feet MSL. C— On unpressurized aircraft, flying above 12,000 feet MSL, pilots shall use oxygen continuously.

Which requirement applies when oxygen is stored in liquid form?. A— Smoking is not permitted within 50 feet of stored liquid oxygen. B— Liquefied oxygen is a hazardous material and must be kept in an isolated storage facility. C— The equipment used to store liquid oxygen must be covered in the certificate holder’s approved maintenance program.

Which is a condition that must be met when a person is administered medical oxygen in flight?. A— The distance between a person using medical oxygen and any electrical unit must not be less than 5 feet. B— A person using oxygen equipment must be seated to avoid restricting access to, or use of, any required exit. C— A person being administered oxygen mus be monitored by equipment that displays and records pulse and respiration.

Which is a requirement regarding the carriage and operation of oxygen equipment for medical use by passengers?. A— No person may smoke within 10 feet of oxygen storage and dispensing equipment. B— When oxygen equipment is used for the medical treatment of a patient, the rules pertaining to emergency exit access are waived. C— No person may connect oxygen bottles or anyother ancillary equipment until all passengers are aboard the aircraft and seated.

If a certificate holder deviates from the provisions of regulations which pertain to medical use of oxygen by passengers, a complete report of the incident shall be sent to the FAA within. A— 7 working days. B— 10 working days. C— 10 days of the deviation.

An unpressurized aircraft with 20 occupants other than the pilots will be cruising at 14,000 feet MSL for 25 minutes. For how many, if any, of these occupants must there be an oxygen supply?. A— Five. B— Two. C— None.

What are the oxygen requirements for passengers if operating at 14,000 feet?. A— 30 minutes for each passenger. B— available for 10% of the occupants. C— available for 10% of the occupants other than the pilots.
