Calibrating A2 ADAHRS on the EKP V

Compass calibration and test flight

Assuming that the calibration is started with the aircraft heading North,

the steps required are:

1. Maintaining heading 000° execute: pitch up + 20°, back to straight

flight and then pitch down -20°

2. Turn left to heading 270° by performing a standard rate turn (the

proper bank will be shown by the flight director). The target heading for

each step is shown as a magenta reference inside the heading tape.

3. Execute pitch up/down maneuvers as described in step #1

4. Repeat steps #2 and #3 for headings 180° and 090°, until reaching

again the original heading.

5. At the end of a successful calibration procedures the compass

instruments is enabled (i.e. red cross removed) and the HSI instrument

correctly shows AHRS as data source, meaning that magnetic

compass data are now available to the EFIS system.

Note: it’s not required to start the procedure heading north. Any starting direction is acceptable.

Note: If the calibration fails or the compass indicator is not enabled, repeat the calibration procedure. If several calibration

attempts fails review the installation location of the A2. Magnetic disturbance could be too high in the selected area.
