OXYGEN SYSTEM
(Continued)
The Oxygen Duration Chart (Figure 7-10) should be used in
determining the usable duration (in hours) of the oxygen supply in your
airplane. The following procedure outlines the method of finding the
duration from the chart.
1. Note the available oxygen pressure shown on the pressure
gage.
2. Locate this pressure on the scale on the left side of the chart,
then go across the chart horizontally to the right until you
intersect the line representing the number of persons making
the flight. After intersecting the line, drop down vertically to the
bottom of the chart and read the duration in hours given on the
scale.
3. As an example of the above procedure, 1400 PSI of pressure
will safely sustain the pilot only for 4 hours and 10 minutes. The
same pressure will sustain the pilot and three passengers for
approximately 1 hours and 20 minutes.
NOTE
The Oxygen Duration Chart is based on a standard
configuration oxygen system having one red color coded
hose assembly for the pilot and orange color coded hoses
for the passengers. If red color coded hoses are provided
for pilot and passengers, it will be necessary to compute

accomplished by computing the total duration available to
the pilot only (from PILOT ONLY line on chart), then
dividing this duration by the number of persons (pilot and
passengers) using oxygen.
When ready to use the oxygen system, proceed as follows:
1. Mask and Hose - SELECT (Adjust mask to face and adjust
metallic nose strap for snug mask fit)
