Ten-year survey of altitude chamber reactions using the FAA training chamber flight profiles

The Federal Aviation Administration since 1962 has trained nonmilitary government-employed flightcrews and civilian pilots in aspects of altitude and its effects on the human body. The standard military altitude chamber flight profile was not used and the reasons are explained. Two different chamber profiles were used for a 10-year period and both included a rapid decompression, but the altitudes attained were limited to 25,000 ft (7,620 m) and 29,000 ft (8,839 m). During the 10-year period cited in this report, 4,759 students were exposed to these altitudes and none experienced an evolved gas problem.
