1.2.3.2 COOLING REQUIREMENTS
While no forced cooling air is required for the G5, it is highly recommended that the
air behind the panel be kept moving (by ventilation or a fan). Units tightly packed in
the avionics stack heat each other through radiation, convection, and sometimes by
direct conduction. Even a single unit operates at a much higher temperature in still
air than in moving air. Fans or some other means of moving the air around electronic
equipment are usually a worthwhile investment.
NOTE: Avoid installing LRUs near heat sources. If this is not possible, ensure that
additional cooling is provided. Allow adequate space for installation of cables
and connectors. The installer will supply and fabricate all of the cables. All wiring
should be in accordance with FAA AC 43.13-1B and AC 43.13-2B.
1.2.3.3 COMPASS SAFE DISTANCE
After reconfiguring the avionics in the cockpit panel, if the unit is mounted less than
12 inches from the compass, recalibrate the compass and make the necessary changes
for noting correction data.
