EFIS Calibration and Configuration
EFIS-D6 Installation Guide 4-5
During magnetic calibration, do not turn the power off on the EFIS-D6. This will cause any
recorded compass calibration data to be lost; the calibration will need to be restarted.
1. Enter the EFIS calibration menu by pressing any button beneath an EFIS page, then
SETUP > MAGCAL. You should see a menu that reads GNDNRT, AIRRGT, and
AIRLFT. If it reads NORTH, EAST, SOUTH, and WEST, you have the EDC-D10A
installed and should proceed with the EDC-D10A heading calibration as described on the
following page.
2. With the plane in the normal flight state (engine running, all instruments and avionics
on), align the plane to point as close as possible to magnetic North. Press the GNDNRT
button (the button’s text will toggle to DONE – do not press this until the maneuver is
complete) and hold the plane still for 10 seconds. After the 10 seconds of holding still,
maneuver the plane smoothly to the right through 540 degrees of heading change at a rate
of 20 to 30 seconds per 90 degrees of change; the whole maneuver should take between 2
and 3 minutes. At the end of the maneuver, the aircraft will be pointing magnetic South.
At this point, press DONE. If at any time, you make a mistake, press DONE, align the
aircraft to point to magnetic North and repeat the process, starting with pushing the
GNDNRT button.
3. Now proceed to take off for the in-flight part of the calibration. After reaching a safe
altitude, head the plane as close as possible to magnetic North. Press the AIRRGT button
(again, the button’s text will toggle to DONE – wait until completing the maneuver
before pressing this), and continue holding a steady North heading for 10 seconds. Then
make a 30 degree banked turn to the right for 540 degrees. The maneuver ends with the
aircraft pointing South. Fly the maneuver as smooth as possible since this will give you
better results. At the end of the maneuver, while still pointing South, press the DONE
button.
4. Maneuver the aircraft to point to magnetic North again. Press the AIRLFT button
(toggling it to DONE – again, refrain from pressing until the maneuver is complete).
Continue holding a steady heading (North) for 10 seconds, and then make a 30 degree
banked turn to the left for 540 degrees. The maneuver ends with the aircraft pointing
South. Fly the maneuver as smooth as possible since this will give you better results. At
the end of the maneuver, while still pointing South, press the DONE button.
5. At any point in the calibration, you may redo a maneuver by pressing the appropriate
button and repeating that step. The order in which you do the 3 maneuvers is not critical
as long as all three maneuvers are performed completely without cycling the power to the
EFIS-D6.
6. When you are satisfied with the three maneuvers, press END. This will cause the EFIS-
D6 to calculate the values needed for calibration. This process can take as long as 10
minutes, during which your EFIS-D6 will appear “frozen.” A message will be displayed
onscreen: CALCULATING MAGNETIC CALIBRATION VALUES.
7. Wait for the message CALIBRATION COMPLETE before attempting to use the EFIS-
D6 or remove power. Press BACK to leave the menu.
At this point the calibration of the EFIS-D6 internal compass is complete. We suggest you
evaluate the performance of the EFIS-D6 heading feature, preferably on a compass rose, and
