heading changes directly on the KSD 100EXP as the scenarios listed below are evaluated.
(3) If the magnetometer heading changes by more than ±2.0 degrees, isolate the wire(s) which
should be moved away from the magnetometer. Alternately, magnetically shielding the wire or
relocating the magnetometer may be a solution.
(4) Check the extent to which the magnetometer heading value changes as nearby rotational
components are moved.
(5) If the magnetometer heading changes by more than ±2.0 degrees, the magnetometer should be
moved further away from the rotational component. Alternately, relocation of the
magnetometer may be required.
3.6.9 KDC 100EXP Installation Considerations
3.6.9.1 KDC 100EXP Location
The KDC 100EXP Data Converter can be mounted with other adjacent avionics equipment. No special
mounting considerations are required for this LRU.
3.6.9.2 KDC 100EXP Orientation
The orientation of the KDC 100EXP does not matter, however, the orientation of the MD32 does - it has
24 different installation orientations.
3.6.10 KTP 73 Installation Considerations
3.6.10.1 KTP 73 Location
To ensure accurate temperature readings, the KTP 73 OAT probe must be mounted to the wing or
fuselage and away from heat sources, e.g. exhaust, engine cowlings, propeller wash. For a single engine
airplane, it is recommended the probe be placed under the wing out of the exhaust stream and not in
direct sunlight. For a twin engine airplane, it is recommended the probe be placed on the underside of
the outer wing, under, or on the side of the nose fuselage outside of the exhaust stream and not in direct
sunlight. It is recommended that the KTP 73 OAT probe be placed near an access panel. A doubler may be
needed based on the skin thickness at the mounting location; check the mounting location for similarly
sized OEM cutouts to determine if a doubler is required. If a doubler is needed, refer to Figure A-15 for a
generic doubler definition to be used with airplane skin thicknesses from 0.016 to 0.032 inches; this
generic doubler defines the minimum thickness, size, and number of rivets required for the KTP 73
installation.
NOTE
FOR PROPER OPERATION, THE KDC 100EXP MUST BE ELECTRICALLY BONDED TO THE
AIRPLANE.
NOTE
THE KTP 73 OAT PROBE HAS NO ICING PROTECTION. IF ICE ACCUMULATES ON THE KTP 73
OAT PROBE, ITS ACCURACY IS UNRELIABLE AND AIR TEMPERATURE MEASUREMENTS
MAY BE INCORRECT.
