SV-MAG-236 Installation and Configuration
SkyView System Installation Guide - Revision AA 20-5
7. The minimum maneuvers for in-flight compass calibration is one 360° turn clockwise,
and one 360° turn counterclockwise. Flying additional maneuvers incorporating pitch
and roll changes will likely improve the in-flight compass calibration.
8. When the quality is as high as you can obtain (above 70, the minimum), push the FINISH
button to complete the in-flight compass calibration. Flying additional maneuvers
beyond the minimum may improve the 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
If, after multiple attempts at in-flight compass calibration, you cannot achieve QUALITY of at
least 70, the SV-MAG-236 cannot sense the earth’s magnetic field with enough precision
(excessive magnetic interference). It should be considered to change the location of the SV-
MAG-236.
Restoring Use of the SV-ADAHRS-200/201 Internal Magnetometer
If you wish to resume the use the SV-ADAHRS-200/201’s internal magnetometer (not use the
SV-MAG-236), here are the steps to follow:
1. Disconnect the SV-MAG-236 from SkyView Network.
2. SETUP MENU > SKYVIEW NETWORK SETUP > CONFIGURE > (one more right click) >
DETECT (button) > FINISH (button). This “removes” the SV-MAG-236 from the SkyView
system.
Any calibrations for the SV-ADAHRS-200/201’s internal magnetometer are intact:
Factory calibration
In-aircraft ground calibration (if performed)
In-aircraft air calibration (if performed)
