In-flight Compass Calibration Procedure:
The in-flight compass calibration should be conducted on a clear, VFR day. Before
commencing the compass calibration, ensure that you have adequate altitude,
clear weather, no traffic, no obstructions in the flight path, great visibility, no
airspace conflicts, etc. It is recommended that clearing turns be performed before
executing each procedure.
It is recommended that you bring someone along for the in-flight compass
calibration procedure. At times the pilot’s attention will be divided between
documentation, configuring SkyView, and maintaining situational awareness.
Confine the flying for the in-flight compass calibration to a specific area to
minimize variations in the earth’s magnetic field during the calibration process (IE,
don’t combine the in-flight compass calibration with a cross-country flight).
While the in-flight compass calibration is optional, it will likely improve the dynamic
performance of the heading indications in many aircraft. It is especially recommended in
aircraft where the SV-ADAHRS-200/201 was, by necessity, installed in an area of the plane that
was not entirely clear of magnetic interference. This is particularly true in steel framed aircraft.
The best compass performance will be achieved by performing the in-flight
compass calibration after the on-ground compass calibration has been performed.
1. If you have two SkyView displays, the in-flight compass calibration can be performed
from either display.
2. After observing the cautions above, push buttons 7+8 to enter the IN FLIGHT SETUP
MENU.
3. Select COMPASS CALIBRATION
4. Right-click the knob to enter the in-flight COMPASS CALIBRATION menu. You will see a
screen similar to this:
