(PSI). The instrument is graduated from 0 to 500 PSI and scaled to 50 PSI. Normal full pressure of
the system is 400 PSI. Note, oxygen pressure readings can drop as altitude increases due to the
cooling of the oxygen tanks. Conversely, the pressure can increase as altitude decreases due to the
warming of the tanks. A rapid decrease of oxygen pressure in level flight or during a descent is
abnormal and may indicate an oxygen system leak or malfunction.

Hydraulic Pressure Gauge
The Hydraulic Pressure Gauge is located on the bottom of the front dash, above the Parking Brake
handle. This instrument indicates fluid pressure in the hydraulic system, measured in pounds per
square inch (PSI). The instrument is graduated from 0 to 2,000 PSI and scaled to 200 PSI
throughout. Normal pressure for the hydraulic system is 1,050 (+/- 50) PSI.
