SUCTION GAGE
The suction gage is calibrated in inches of mercury and indicates the suction
available for operation of the attitude indicator. The desired vacuum range
is 4.4 to 5.2 in.Hg.
A vacuum reading out of this range may indicate a system malfunction or
improper adjustment. In this case, all pneumatic instruments should be
considered unreliable.
The suction gage is located on L.H. panel of pilot’s instrument panel.
