OXYGEN SYSTEM
(MODEL T210)
PILOT'S OPERATING HANDBOOK
SUPPLEMENT
alcohol will usually necessitate the use of oxygen at less
tha
n 10,000
feet.
The Oxygen Duration Chart (figure 2) 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 6 hours and 20 minutes. The same
pressure will sustain the pilot and three passengers for approxi-
~
\
mately 2 hours and 10 minutes.
NOTE
The Oxygen Duration Chart is based on a standard config-
uration 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 new
oxygen duration figures due to the greater consumption of
oxygen with these hoses. This is accomplished by comput-
ing 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 oxy-
gen.
SECTION 2
LIMITATIONS
There is no change to the airplane limitations when oxygen equipment
is installed.
SECTION 3
