Ultra EFIS

Taxi the aircraft to the airports compass rose or an open field free from magnetic

disturbances.

Have the aircraft nose pointed to the magnetic north (0°) radial on the airport compass

rose.

Note: use a magnetic compass for your reference if you execute the procedure in an open

field free from magnetic disturbances).

Set the aircraft in level and straight flight attitude by using jacks or blocks.

Note: Make sure that the horizon line of the Ultra is aligned with the aircrafts straight & level

flight attitude.

IMPORTANT

: Perform this test with all on-board electronic devices switched ON.

IMPORTANT

: Let the Ultra system warm up and stabilize for about 5 minutes before

starting the calibration.

IMPORTANT

: Check on the HSI display if the Ultra receives a GPS fix.

Note: in case of no GPS reception the Ultra reports on the PFD and HSI page in RED “NO

GPS”.

rose.

Set the aircraft in level and straight flight attitude by using jacks or blocks.

Let the system stabilize for about 30 seconds and make sure that the aircraft is not moving.

Then confirm by pressing “NEXT”.

Note: The calibration calculation for east direction will start and a counter will inform of the

progress.

STEP 4: Calibration calculation for south direction
