11.3 UC10x Installation
11.3.1 Avionics Cooling Requirements
The greatest single contributor to increased reliability of all modern-day avionics is to limit the maximum operating
temperature. While modern day individual circuit designs consume much less electrical energy, the watts per cubic
inch dissipated within avionics units remains much the same because of high density packaging techniques utilized.
Consequently, the importance of providing avionics stack cooling is essential to the life span of the equipment.
11.3.2 Installation Location
The transponder is to be fitted in a suitable place on the aircraft. This is usually the avionics compartment. The
mounting place shall be at least 30 cm from the magnetic aircraft compass, to avoid any interference to the
magnetic compass by the transponder. For installation in a more severe electromagnetic environment use shielded
cable connectors and a common shielding for the transponder wiring. Select a position that is not too close to any
high external heat source. The transponder itself is not a significant heat source and does not need to be kept
away from other devices for this reason.
11.3.3 Mounting Hole Pattern
Mounting fasteners (when provided) are included for convenience and may not be suitable for all installations. You
should reference individual equipment chapters for information regarding installation instructions.
The appropriate mounting pattern hole size and spacing will vary depending upon mounting plate/surface material
and method of drill (machine or hand). The pattern below will be appropriate for most installations, which uses a
0.101” hole (ANSI drill size 38)
38
. Some customers may need to increase the hole size to 0.104” (ANSI drill size 37)
39
or 0.110” (ANSI drill size 35)
40
, depending on the tolerance of the machine (or person) performing the drill
operation.
