Oxygen Duration Chart
Bold-faced numbers indicate 100% oxygen.
Light-faced numbers indicate diluter demand.
Prior to overwater flights, plan flights so that enough oxygen will be
available for all occupants, in the event of pressurization failure.
For cabin altitudes of 10,000 ft and above, oxygen duration includes
cabin altitude ascent time from 8,000 ft to final stabilized cabin alti-
tude.
The oxygen duration for the 7,000-ft and 8,000-ft cabin altitude pro-
vides information for flight planning when supplemental oxygen is
required.
To calculate oxygen duration for a less than fully charged system,
the following formula may be used: Duration = Duration from chart x
(system pressure ÷ 1,850).
