The equipment should be installed in the aircraft in a manner consistent with
acceptable workmanship and engineering practices, and in accordance with the
instructions set forth in this publication. To ensure the system has been properly
and safely installed in the aircraft, the installer should make a thorough visual
inspection and conduct an overall operational check of the system, on the ground,
prior to flight.
AFTER INSTALLATION OF THE CABLING AND BEFORE
INSTALLATION OF THE EQUIPMENT, A CHECK SHOULD
BE MADE WITH THE AIRCRAFT PRIMARY POWER SUP-
PLIED TO THE MOUNTING CONNECTOR, TO ENSURE
THAT POWER IS APPLIED ONLY TO THE PINS SPECIFIED
IN THE INTERWIRING DIAGRAMS IN
Installation should be accomplished using the guidelines of FAA Advisory Circular
43.13-2A Change: 2 ACCEPTABLE METHODS, TECHNIQUES AND PRAC-
TICES -- AIRCRAFT ALTERATIONS.
The KMH 880/KTA 870 System installation will conform to standards designated
by the customer, installing agency, and existing conditions as to the unit location
and type of installation. However, the following suggestions should be carefully
considered before installing your system.
2.2.2 Avionics Cooling Requirements
The most important contribution to improved reliability of all avionics equipment is
to limit the maximum operating temperature of the individual unit, whether panel
mounted or remote mounted. While modern circuit designs consume less total
energy, the heat dissipated per unit volume (Watts/cubic inch) remains much the
same due to contemporary high density packaging techniques. While each indi-
vidual unit may not require forced air cooling, the combined heat generated by
several units operating in a typical panel or rack, can significantly degrade the reli-
ability of the equipment. Consequently, the importance of providing force air cool-
ing to avionics equipment mounted in either a panel or rack, is essential to the life
span of the equipment. Adequate provisions for cooling should be incorporated
during the installation.
