9.4 GYRO CAL

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. Running the Gyro Calibration
procedure is required to complete this Service Bulletin, and can be run
periodically to respond to higher rates of observed DG drift.
For more information on Gyro Calibration, reference the procedure as
described in "AV-30-E Installation Manual" UAV-1004234-001 Rev C
Section 13.2.2.
To perform the calibration, the aircraft must be completely motionless
and on the ground. It should be located in a hangar and must not be
affected by wind or other sources of aircraft movement. If unable to
perform the procedure while standing outside the aircraft, do not
leave the aircraft during the procedure.
The Gyro Calibration feature can be accessed by selecting "GYRO CAL"
from the Installation Menu. Follow the procedure in Section 9 to access the
Installation Menu.
