AvMap Ultra EFIS
Taxi the aircraft to the airports compass rose or an open eld 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
eld free from magnetic disturbances).
Set the aircraft in level and straight ight attitude by using jacks or blocks.
Note: Make sure that the horizon line of the Ultra is aligned with the aircrafts straight & level
ight 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 x.
Note: in case of no GPS reception the Ultra reports on the PFD and HSI page in RED “NO
GPS”.
STEP 2: Calibration calculation for north direction
Enter the SETUP mode by keeping the rotation knob pressed for 5 seconds and release
(see chapter 4 for further details). Push again the rotor knob, select “CALIBRATE” to enter
the calibration menu, then select “COMPASS” and select “CALIBRATE” (“Mag clear done”
message will pop up on the display).
The Ultra display shows: “Point to NORTH. Press NEXT when ready”.
Make sure that the aircraft nose is pointed to the magnetic north (0°) radial on the airport
compass rose and make sure that the aircraft is not moving. Then conrm by pressing
“NEXT”.
Note: The calibration calculation for north direction will start and a counter will inform of the
progress.
STEP 3: Calibration calculation for east direction
The Ultra display shows: “Point to EAST. Press NEXT when ready”.
Have the aircraft nose pointed to the magnetic east (90°) radial on the airport compass
rose.
Set the aircraft in level and straight ight attitude by using jacks or blocks.
Let the system stabilize for about 30 seconds and make sure that the aircraft is not moving.
Then conrm 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
The Ultra display shows: “Point to SOUTH. Press NEXT when ready”.
Have the aircraft nose pointed to the magnetic south (180°) radial on the airport compass
