 ERR: NOT ENOUGH DATA FOR XXXXXX TURN. One of the 3 maneuvers did not take
enough time for the EFIS-D10A to collect enough data. Please perform just the listed
maneuver again, ensuring that you take at least 2 minutes to perform the turn.
 ERR: HOLD N LONGER BEFORE XXXXXX TURN. The EFIS-D10A did not see enough
data for the 10 second north-bound section of the turn. Repeat the listed maneuver, ensuring
that you spend 10 seconds pointed north before beginning the turn.
 ERR: XXXXXX 540 DEG TURN NOT COMPLETED. The EFIS-D10A did not see a
complete 540 degree turn. Repeat the listed maneuver, ensuring that you turn through the
entire 540 degrees, ending up pointed south.
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-D10A. The EFIS-D10A will then
perform some calculations to ensure an accurate calibration.
During magnetic calibration, do not turn the power off on the EFIS-D10A. 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-D10A and EDC-D10A installed in aircraft.
2. Magnetic inclination angle and intensity properly entered into the EFIS-D10A 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-D10A (via the headphone test described in the installation section), and have
located a suitable place to perform the calibration, perform the following steps:
1. Turn on the EFIS-D10A 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-D10A, 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-D10A.
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.
