Equipment Installation Procedures

2.3.1 Cooling Requirements

Forced air cooling of the KMA 28 is not required. However the unit should be kept away
from heat producing sources (i.e. defrost or heater ducts, dropping resistors, heat produc-
ing avionics) without adequate cooling air provided.

2.3.2 Mounting Requirements

The KMA 28 must be rigidly mounted to the instrument panel of the aircraft structure and
within view and reach of the pilot position(s). Installation must comply with FAA Advi-
sory Circular AC 43.13-2A. The unit may be mounted in any area where adequate clear-
ance for the unit and associated wiring bundle exist.
Avoid installing the audio panel close to high current devices or systems with high-
voltage pulse type outputs, such as DME or transponders.
