Oxygen Duration Chart – Dual Bottle
Aircraft with 6600214-1, -2, -3, -4, and -9 Crew Masks
Bold-faced numbers indicate 100% oxygen.
Light-faced numbers indicate diluter demand.
Prior to over water 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 time
includes cabin altitude ascent time from 8,000 ft to final stabilized
cabin altitude.
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).
