EDC-D10A HEADING CALIBRATION (ON GROUND ONLY)
The procedure for in-plane calibration of the EDC-D10A involves pointing the aircraft in four
directions and taking data at each direction using the EFIS-D100. The EFIS-D100 will then
perform some calculations to ensure an accurate calibration.
During magnetic calibration, do not turn the power off on the EFIS-D100. This will cause
any recorded compass calibration data to be lost; the calibration will need to be restarted.
To perform the calibration, you will need the following:
1. EFIS-D100 and EDC-D10A installed in aircraft.
2. Magnetic inclination angle and intensity properly entered into the EFIS-D100 per the
section above.
3. An accurate method of aligning the aircraft with magnetic North, East, South, and West,
such as an airport’s compass rose.
Once you have the installation completed, have verified that your EDC-D10A communicates
with the EFIS-D100 (i.e., you see the heading tape displayed on the EFIS main page), and have
located a suitable place to perform the calibration, perform the following steps:
1. Turn on the EFIS-D100 and allow it to warm up for at least 15 minutes before performing
the calibration.
2. Align the aircraft pointing magnetic North as closely as possible.
3. On the EFIS-D100, enter the menu system by pressing any button beneath an EFIS page
(except the far left or far right hotkeys) and press MORE > SETUP > MORE > MORE >
MAGCAL. You should see a menu that reads NORTH, EAST, SOUTH, and WEST. If
you do not, then the EDC-D10A is not properly communicating with your EFIS-D100.
4. Press the NORTH button; you will see the message, COLLECTING DATA FOR
NORTH along with a 15 second timer. Let the time run out before proceeding.
5. Align the aircraft pointing magnetic East as closely as possible.
6. Press the EAST button; you will see the message, COLLECTING DATA FOR EAST
along with a 15 second timer. Let the time run out before proceeding.
7. Align the aircraft pointing magnetic South as closely as possible.
8. Press the SOUTH button; you will see the message, COLLECTING DATA FOR
SOUTH along with a 15 second timer. Let the time run out before proceeding.
9. Align the aircraft pointing magnetic West as closely as possible.
10. Press the WEST button; you will see the message, COLLECTING DATA FOR WEST
along with a 15 second timer. Let the time run out before proceeding.
11. Press the END button. This will cause the EFIS-D100 to pause as it calculates. This
pause should last between 1-20 seconds. However, if the collected data is poor, this can
take as long as 5 minutes. A message will be displayed onscreen: CALCULATING
MAGNETIC CALIBRATION VALUES.
