Gyro Calibration

As units age or experience unusual conditions, the precision gyroscopic
sensors may need to be re-calibrated. This can be accomplished in the field
using the procedure noted here. At least 15 minutes of warmup is required
before performing the AV-30-C gyro calibration.
1. Before applying power, press and hold the center rotary knob and apply
power. As the splash screen appears, check that a minimum version of
2.1.2 is displayed. Gyro Calibration must be completed on all units with
software version 2.1.2 or later.
2. With the AV-30-C in the AI mode, enter the "Install Menu" page by
pressing and releasing the left button repeatedly until the 3
displayed. The aircraft must be on the ground with no movement.
3. It is critical to ensure the aircraft is completely motionless and on the
ground during the next several steps. The aircraft should be in a hangar
and must not be affected by wind or other sources of aircraft movement.
Do not leave the aircraft during the countdown.
4. Rotate the "Install Menu" to "GYRO CAL" and press the center button to
choose calibration. If sufficient warmup time has not elapsed, a "Not
ready to calibrate" message and countdown will be indicated. Otherwise,
initiate calibration by pressing the right button.
