A ilot's oxygen panel on the side wall near the pilot's arm rest contains a cylinder pressure gage
(ekective~aquantit gage - see Fig. 2 or 3) anda controlknobwhich is mechanically connectedto
the shuto#valve at tiecylinder. The sup

imum airplane operating altitude (see Section II Limitations)while at lower altitudes the reducin

Four oxy en outlets are provided: three in the left sidewall behind the pilot's seat for the conve-
P
nience o passengers and one in the pilot's oxy en anel. Oxygen flows from the outlets only
when a mask hose is connected. Four artial re- rea hingtype masks are provided, eachwith vi-

pilot's mask is
a permanent type with a built-in microphonefor ease of radiocommunicaion while
usingoxygen. To usethe mask-microphone, connect itsleadtothe microphonejack locatedleftof

OXYGEN SYSTEM M2OJ, M20K, M20L, M20S
For FAA requirements concerning sup lemental oxy en, refer to FAR 91.32. Supplemental oxy-
ger~should be used by all occupants w P7 en cruislng a f! ove 12,500feet. It IS often advisable,to use
oxygen at altitudes lower than 12,500 feet under conditions of night flying, fat~gue,or periods of
ph siolo icalor emot~onald~sturbances.Also the habitualandexcessive useof tobacco or alcohol
wlYusuajy necessitate the use of oxygen at less than 10.000feet.
The oxy en duration chart (Fi . 2 or 3) should be used in determining the usable duration (in
9 7
hours) o the oxygen suppl in he airplane for the chosen cruising altitude. The following proce-
dure outlines the methodoffinding the duration from the chart:
1. Note the available oxygen pressure shown on the pressure gage.
2. Locatethis ressureon the scale on the left sideof the chart. Then go across the chart horizon-
tally to the r
It until intersecting the dia anal line which represents the number of persons on
9
board. From?hat intersection drop vertlca ly down to the heavy line, marked 30.000'.
3. From this point on the heav line,follow thetrendofthe curved lines,down to the horizontal line
re resentingcruise altitude. Yhen drop vertically down to the bottom ofthe chart and readthe du-
ragon n hours given on the scale.
4. As an example of the above procedure, 1400 PSI of pressure will safely sustain the ilot and
one passenger for 3 hours and 30 minutes (Fig. 2) or 5 hours and 13 minutes FI 3)at 21.000 ft:
or 7 hours and 59, minutes (Fig. 3).
d
however,cruisin at 20,000 ft: would permit an oxygen duration of 5 hours an 1 minutes (Fig. 2j
Lightcrew loads and relatively low altitudes will permit ox en durations off the chart. Such dura-
tions can be calculated by determining the duration at 3i800feet
(by steps 1and 2 above) and
multiplyin by the "duration multiplier" shown on the right of the appro riate cruising altitude. Ex-
am le:,(Zg.2 only) ilot only at 1600 PSI has 7.9 hours duration at 3 6 ,000 ft., times 1.5 duration

tude for the number of persons on board can permit flight planning for several fuel stops, without
need for recharging the oxygen system at each stop.
I SECTION II - LIMITATIONS~
There is no change to the Airplane Limitations when oxygen equipment is installed.
1 ) "Use aviators oxygen only"
Location: at filler port.
2) "Oxygen-No Smoking When in Use"
Location: at oxygen outlets
NOTE
Only masks which have end fittings marked with a green
band are acceptable for use with this system.
There is no change to the Airplane Emer ency Procedureswhen oxy en e ui ment is installed.
In the event of oxygen loss above 20,080 ft. refer to AFM

Prior to flight, check to be sure that therejs an ly for.the trip, by notin the

oxygenpressurega e read~ng,andreferr~ngto
(Fig. 2 or 3). Also c eck
WARNING
Greasy lipsticks and waxed mustaches have been knownto ignite spontaneously
inside oxygen masks. Passengers should be suitably advised prior to flight.
WARNING
For safety reasons no smoking should be allowed inthe airplane while oxygen is
being used.
When ready to use the oxygen system, proceed as follows:
1. Maskand Hose
- SELECT. Adjust masktoface and adjust metallicnosestrap for snug mask
fit.
2. Delivery Hose - PLUG INTO OUTLET assigned to that seat.
NOTE
When the oxygen system isturned on, oxygen will flow continuously at the
appropriate rate of flow for the altitude without any manual adjustments.
3. Oxygen Supply Control Knob - ON.
4. FaceMask Hose Flow Indicator- CHECK. Oxygenisflowing ifthe indicator isbeingforced to-
ward the mask.
5. Delive Hose
- UNPLUG from outlet when discontinuing use of oxygen. This automatically
X stops the ow of oxygen.
6. Oxygen Supply Control Knob - OFF when oxygen is nolonger required.
WARNING
Proper oxygen flow is critical to pilotlpassenger safety, especially at altitudes
above
20,000 ft. MSL. It is important to monitor closely the face mask hose flow
indicator to ensure oxygen isconstantly flowing to the mask. A green indication
on the flow indicator denotes proper oxygen flow. Always place the flow indicator
ina positionwhere itis inthe normal scan area of the cockpit.
Referto duration chart (Fig. 2 or 3) for safe operational quantities.
