3. INSTRUMENT INSTALLATION
This section provides you with the information needed to physically and electrically install the
EFIS-D60.
Selecting a Remote Compass Module Location
Finding a good location for the EDC-D10A
remote compass module is critical to an
accurate EFIS-D60 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 goo
location for yo

• 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.
• The ED
the aircraft (away from magnetic interference)
such that its pitch is as close to that of the
EFIS-D60 as possible. It does not need to b
directly along any axis of the EFIS-D60. 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 pitc
roll, and yaw as the EFIS-D60 with respect
to the airframe. We recommend that you use
an electronic level, if available, to make
sure the EDC-D10A is aligned with the
