EQUIPMENT
INSTALLATION
The
INS 422
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 considered
before installing the
INS 422
.
2.3.1
AVIONICS COOLING REQUIREMENTS FOR PANEL MOUNTED
EQUIPMENT
The most important contribution to improved reliability of today’s
avionics equipment is to limit the maximum operating temperature of
each unit. While modern designs use less total energy, the heat
dissipated per unit volume (Watts/Cubic inch) remains much the
same due to the contemporary high-density packaging techniques.
Although the
INS 422
does not require forced air-cooling, the
combined heat generated by several units operating in the typical
panel within close proximity, may significantly degrade the reliability
to the equipment if provisions for adequate cooling are not
incorporated in the initial installation.
2.3.2 PRE-INSTALLATION
INFORMATION
Always follow good avionics installation practices per FAA Advisory
Circulars AC43.13-1B, 43.13-2A, or later FAA approved revisions of
these documents.
NOTE:
It is recommended that aircraft be equipped with at a
minimum of two NAV and two COM receivers for use IFR. With
the loss of either a NAV or COM, the second system will be
available for use and provide a comfortable margin of safety.
