When an order is placed for an attitude gyro, it is important that the following information be given:

Instrument model number Aircraft voltage (14VAC or 28VAC) Panel tilt angle Lighted or unlighted #lighting voltage) Fixed or movable pointer Optional slip indicator Note: There is an extra charge to reset the tilt angle after purchase.

Panel tilt refers to the tilt angle of an aircraft's panel. The tilt angle is any deviation from the vertical axis of the control panel in level flight. When ordering an attitude gyro indicator, it is very important to know the tilt angle of the aircraft panel. Check your aircraft equipment manual or inspect the labeling on the side of your gyroscope. Installing the incorrect angle will cause the horizon to show a climb or a dive. If panel tilt is not known, the manufacturer of the aircraft should be able to provide that information. An attitude gyro indicator can be calibrated for a panel tilt from 0-14 degrees and should be specified when ordering. A label is attached to the gyro to indicate the tilt calibration of each unit. If a newly installed attitude gyro settles more than ± 1½ degrees pitch above or below where the expected horizon should be, then panel tilt or aircraft trimming issues should be suspected.
