The Federal Aviation Regulations (FARs) set the requirements for the use of oxygen while on aircraft in Section 91.211 of the FAA’s General Operating and Flight Rules. The section applies to pilots and passengers, including skydivers, even though there is no mention of oxygen use in the more familiar Part 105, Parachute Operations. Jump pilots are required to use supplemental oxygen above 14,000 feet mean sea level (MSL), and supplemental oxygen must be provided to each skydiver when the aircraft is above 15,000 feet MSL. The USPA Basic Safety Requirements also mandate the use of supplemental oxygen for skydives above 15,000 feet MSL. more »
