9.5 MAG CAL
If the AV-30 has an internal magnetometer, then an initial Mag Calibration
needs to be completed. This need will be indicated by a red flag indicating
“NOMAG”, once the “ALIGN” flag extinguishes.
For more information on Mag Calibration, reference the procedure as
described in “AV-30-E Installation Manual” UAV-1004234-001 Rev C
Section 13.2.3.
The Mag Calibration feature can be accessed by selecting “MAG CAL”
from the Installation Menu. Follow the procedure in Section 9 to access the
Installation Menu.
1. The Mag Calibration must take place in-flight. It cannot be performed
on the ground. Ensure the Installation Menu is accessible before
departure.
2. Once established in flight, access the Installation Menu, and rotate
the center knob until “MAG CAL” is displayed. Push the center button
to enter calibration mode. Confirm by pushing the right button.
3. Fly for 10 minutes. Four, 360-degree standard rate turns will need to
be completed. Each turn will represent 25% of the total.
