For more information on Gyro Calibration, reference the procedure as
described in “AV-30-E Installation Manual” UAV-1004234-001 Rev E (or
latest available), 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. At least 15 minutes of warmup is required
before performing a Gyro Calibration. Follow the procedure in Section 9 to
access the Installation Menu.
1. Ensure the aircraft is completely motionless and on the ground during
the next several steps.
2.
In the Installation Menu, rotate the center knob until “GYRO CAL” is
displayed. Push and release the center knob to enter calibration
mode. If sufficient
warmup time has not elapsed, a “Not ready to
calibrate” message and countdown will be indicated. Otherwise,
initiate calibration by pushing the right button.
3.
“Calibration in progress” will be displayed with a percentage
complete.
