OXYGEN DURATION - HOURS
Figure 2. Oxygen Duration Chart
For FAA requirements concerning supplemental oxygen, refer to FAR
91.32. Supplemental oxygen should be used by all occupants when cruising
'l,bove 12,500 feet. As described in the Cessna booklet "Man At Altitude," it
l
is often advisable to use oxygen at altitudes lower than 12,500 feet under
conditions of night flying, fatigue, or periods of physiological or emo
tional disturbances. Also. the habitual and excessive use of tobacco or
alcohol will usually necessitate the use of oxygen at less than 10,000 feet.
