OXYGEN
In the event of oxygen loss above 12,500 ft. return to 12,500 ft as soon as feasible. Refer to SEC-
TION X for the physiological characteristics of high altitude flight.
ALTERNATE STATIC SOURCE
The alternate static air source should be used whenever it is suspected that the normal static air
sources are blocked. Selecting the alternate static source changes the source of static air for the
altimeter, air speed indicator and rate-of-climb from outside of the aircraft to the cabin interior.
When alternate static source is in use, adjust indicated airspeed and altimeter readings accord-
ing to the appropriate alternate static source airspeed and altimeter calibration tables in SEC-
TION V. The alternate static air source valve is located on the instrument panel below pilot’s con-
trol wheel shaft.
NOTE:
When using Alternate Static Source, pilot’s window and air vents
MUST BE KEPT CLOSED.
