Calibration Procedure:
1. While observing conditions listed above, push Buttons 7 and 8 simultaneously to enter
IN-FLIGHT SETUP MENU.
2. Select COMPASS CALIBRATION.
3. Click knob to enter in-flight COMPASS CALIBRATION menu (see Figure 83 ).
Figure 83: In-Flight Compass Calibration Menu
4. Push START button to begin calibration.
5. View NEW CALIBRATION section of menu. The goal of the in-flight compass calibration
is to achieve a compass calibration “quality” of at least 100.
6. Perform calibration maneuvers. The minimum maneuvers for in-flight compass calibration
are one (1) 360° turn clockwise, and one (1) 360° turn counterclockwise. Flying additional
maneuvers that incorporate pitch and roll changes will likely improve the in-flight compass
calibration.
7. When the quality is as high as you can obtain (minimum is 70), push the FINISH button
to complete the in-flight compass calibration. Flying additional maneuvers beyond the
minimum may improve in-flight compass calibration but will not make it worse.
QUALITY of 70-99 is acceptable, but not optimum; the accuracy of your magnetic heading
may not be acceptable. Additionally, a sub-optimal quality may have the following effects:
•
Degraded performance of the SkyView Autopilot (AP) in HDG and NAV modes.
•
Degraded accuracy of wind direction and velocity.
