3. Installation Overview
air

of the cockpit and viewing/operating the ATD. The location should be suchthat the ATD is
not blocked by the glare shield on top, or by the throttles, control yoke, etc. on the bottom.
Try not to mount ATD in a location that is exposed to sunlight focussed by the canopy.
ATD-57 and ATD-80 are designed to be mounted in the aircraft instrument panel. ATD-11 is
designed to be installed externally on a mount or in the aircraft instrument panel.
3.5 Air Circulation and Cooling
ATD-57 does not require external cooling. However lower operating temperatures extend
equipment life. Reducing the operating temperature increases the mean time between
failures (MTBF).
Units tightly installed 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.
3.6 Compass Safe Distance
After reconfiguring the avionics in the cockpit panel, if ATD-57 is mounted less than 30 cm
from the compass, recalibrate the compass and make the necessary changes for noting
correction data.
