FIGURE 7--13 AVOX OXYGEN DURATION CHART (77.1 CU.FT.)
The Avox oxygen system duration chart (Fig. 7--12 or Fig. 7--13) should be used in determining
the usable duration (in hours) of the oxygen supply in the airplane for the chosen cruising alti-
tude. The following procedure outlines the method of finding the duration from the chart:
1.
Note the available oxygen pressure shown on the pressure gauge.
2.
Locate this pressure on the scale on the left side of the chart. Then go across the chart horizon-
tally to the right until intersecting the diagonal line which represents the number of persons on
board. From that intersection drop vertically down to the heavy line, marked 30,000 ft..
