1. Park the aircraft on a level surface and start the engine.
2. Press any button on the EFIS display to bring up the soft key labels. Press SET
MENU soft key, then scroll to and select AHRS Maintenance. Locate Magnetic
Heading field on this screen.
3.
NOTE:
Do not use the heading data shown on the heading tape on the PFD for
calibration because this is a composite reading of several other pieces of
information. The Magnetic Heading field contains instantaneous data on the
magnetic heading only.
4. Observe the Magnetic Heading and verify that it does not change by more than
+/- 2 degrees while doing the following:
a. Turn on and off any electrical equipment whose wiring passes within 2 feet
of the magnetometer.
b. Move all flight controls from limit to limit.
c. Shut down the engine and observe the heading while the engine is not
running, noting any differences.
d.
For aircraft with retractable landing gear:
If the magnetometer is
located within 2 feet of retractable landing gear, support the aircraft using
proper jacking equipment, then repeat Step 1 while operating the landing
gear.
