4. INSTRUMENT INSTALLATION
This section provides you with the information needed to physically and electrically install the
FlightDEK-D180.
Selecting a Remote Compass Module Location
Finding a good location for the EDC-D10A
remote compass module is critical to an
accurate FlightDEK-D180 heading display.
Keep in mind that calibration can
compensate for small static magnetic fields
superimposed upon the earth’s field;
it cannot take into account dynamic
effects like AC currents, non-
constant DC currents and non-
stationary ferrous material (e.g., an
electric turn coordinator). Use the
following suggestions to help you
find a good location for your EDC-
D10A.
 Keep the EDC-D10A away from
any source of magnetic fields (such as
electrical equipment and current-carrying
wires) and ferrous material.
 Move a handheld compass throughout the
space surrounding your location to get a r
idea of the suitability of your chosen location
If the needle deviates significantly from
magnetic north in any given area, that locatio
would not be ideal for the EDC-D10A.

FlightDEK-D180 as possible. It does not
need to be directly along any axis of the
FlightDEK-D180. It should be mounted
with the long axis parallel to the wings, the
electrical connector facing toward the front
of the plane, and the mounting tabs on the
bottom. The bracket used to hold the EDC-
D10A must hold the EDC-D10A at the
same pitch, roll, and yaw as the FlightDEK-
D180 with respect to the airframe. We
