- 14 CFR § 91.211 Supplemental oxygen.
Supplemental oxygen. (a) General. No person may operate a civil aircraft of U.S. registry— (1) At cabin pressure altitudes above 12,500 feet (MSL) up to and including 14,000 feet (MSL) unless the required minimum flight crew is provided ... with and uses supplemental oxygen for that part of the flight at those altitudes that is of more than 30 minutes duration; (2) At cabin pressure altitudes above 14,000 feet (MSL) unless the required minimum flight crew is provided…

Electrical Pulse-Demand Oxygen System Portable electrical pulse-demand oxygen systems deliver oxygen by detecting an individual’s inhalation effort and provide oxygen flow during the initial portion of inhalation. Pulse demand systems do not waste oxygen during the breathing ... cycle because oxygen is only delivered during inhalation. Compared to continuous-flow systems, the pulse-demand method of oxygen delivery can reduce the amount of oxygen needed by 50–85 percent. Most pulse-demand oxygen systems also incorporate an internal…
- Chapter 7: Aircraft Systems › Oxygen Systems › Pressure-Demand Oxygen Systems
Pressure-Demand Oxygen Systems Pressure-demand oxygen systems are similar to diluter demand oxygen equipment, except that oxygen is supplied to the mask under pressure at cabin altitudes above 34,000 feet. Pressure-demand regulators create airtight and oxygen-tight ... seals, but they also provide a positive pressure application of oxygen to the mask face piece that allows the user’s lungs to be pressurized with oxygen. This feature makes pressure demand regulators safe at altitudes above 40,000 feet…
- 14 CFR § 91.108 Use of supplemental restraint systems.
supplemental restraint systems. confirmation from the operator or any individual providing the supplemental restraint system of the system's continued serviceability and readiness for its intended purpose before each takeoff; (3) May only permit an individual to use a supplemental ... operator or the pilot in command if that individual complies with the sizing criteria for which the supplemental restraint system is rated; (4) Has final authority regarding whether the supplemental restraint system may be used during flight operations…
- Chapter 7: Aircraft Systems › Oxygen Systems
regulators approved up to 45,000 feet are designed to provide 40 percent cylinder oxygen and 60 percent cabin air at lower altitudes, with the ratio changing to 100 percent at the higher altitude. Pilots should be aware ... danger of fire when using oxygen. Materials that are nearly fireproof in ordinary air may be susceptible to combustion in oxygen. Oils and greases may ignite if exposed to oxygen and cannot be used for sealing the valves and fittings…
- Chapter 7: Aircraft Systems › Oxygen Systems › Servicing of Oxygen Systems
Servicing of Oxygen Systems Before servicing any aircraft with oxygen, consult the specific aircraft service manual to determine the type of equipment required and procedures to be used. Certain precautions should be observed whenever aircraft oxygen systems ... serviced. Oxygen system servicing should be accomplished only when the aircraft is located outside of the hangars. Personal cleanliness and good housekeeping are imperative when working with oxygen. Oxygen under pressure creates spontaneous results when brought in contact with petroleum…
