5. Installation Planning
A. General
The following paragraphs contain data for the initial installation of CAS-100 and supply the
instructions about the location and assembly of the different components of the system. The
CAS-100 system must installed in the aircraft in a procedure consistent with permitted quality
and engineering procedures and as shown in the instructions set forward in this publication.
To make sure that the system has been correctly and safely installed in the aircraft, the installer
must make a full visual inspection and do the post-installation/operational check of the system
on the ground before flight.

CAUTION: AFTER THE INSTALLATION OF THE CABLES AND BEFORE INSTALLATION
OF THE EQUIPMENT, A CHECK MUST BE MADE WITH AIRCRAFT PRIMARY
POWER SUPPLIED TO THE UNIT CONNECTORS TO MAKE SURE THAT
POWER IS APPLIED ONLY TO THE PINS SPECIFIED IN THE INTERWIRING
DIAGRAMS, FIGURE 2015.

B. Location of Equipment
(1) TCAS Processor Location
The TCAS processor is installed in one available remote location that is free of too much
heat and vibration and gives reasonable access for inspection and maintenance. To
achieve the maximum performance, the TCAS processor must be installed adjacent to
other receiver/transmitters or boxes with equivalent functions. The length of cables from
the TCAS processor mounting tray connector to other system units, except the TCAS
antennas, is not important. This is because the TCAS unit interfaces are designed with
high impedance input, low impedance output, and low noise permitted properties. If
ARINC cooling is not supplied, a TCAS processor mounting tray with a blower assembly
must be used to supply the unit with forced-air cooling. Air space must be given between
and around the unit. Outline drawing, Figure 2006, shows TCAS processor dimensions.

particulars and interconnects.
(2) TCAS Antenna Location
The CAS-100 system uses a top-mounted directional antenna and either a
bottom-mounted directional or omnidirectional antenna.

Refer to antenna outline drawings in Figures 2007, 2008, 2009, and 2010, and if
applicable, manufacturer documentation for the TCAS antennas.

The top directional TCAS antenna must be installed within 5 degrees of the center line
of the aircraft and as far forward on the constant radius portion of the fuselage as
possible.
