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 10 minutes of warmup is
required before performing the AV-30 gyro calibration.
1. Before applying power, push and hold the center rotary knob and
apply power. As the splash screen appears, check that a minimum
version of 2.1.1 is displayed. Gyro Calibration must be completed on
all units with software version 2.1.1 or later
2. With the AV-30 in the AI mode, enter the "Install menu" page by
pressing and releasing the left button repeatedly until the 3rd menu is
displayed. The aircraft must be on the ground with no movement.
