C. Control Panel Provisions
Mechanical installation data for the ACSS ATC/TCAS Control Panels is shown in
Figure 2−8 and Figure 2−9. The control panel is supplied in either a dual Mode S/TCAS
configuration shown in Figure 2−8, or an ATCRBS−Mode S/TCAS configuration shown in
Figure 2−9.
Mechanical installation data a typical Gables GXXXX Series ATC/TCAS control panel is
shown in Figure 2−10.
It should be noted that various other types of controllers (Radio Management Units or
EFIS Display Controllers) can be used to control the TCAS display. If a controller other
than a ACSS ATC/TCAS control panel is used, refer to that particular unit’s manual for
installation data.
D. VSI/TRA Provisions
Mechanical installation data for the ACSS VSI/TRA display is shown in Figure 2−11. The
VSI/TRA is usually used as a direct replacement for the existing 3−ATI form VSI indicator
currently mounted in the cockpit. Replacement of the installation clamp may be
necessary if the previous clamp is less than 2−inches deep. Some older aircraft clamps
do not provide sufficient mechanical support.
If a ACSS VSI/TRA is used as the TCAS display source, and an Air Data Computer is not
available to provide vertical speed signals to the display, the installation must include a
ACSS PTM to supply air data signals to the VSI/TRA. These signals are derived from a
static pneumatic input.
E. Pressure Transducer Module (PTM) Provisions
Mechanical installation data for the PTM is shown in Figure 2−12. The PTM is configured
to be mounted on a mounting bracket designed for use in a restricted access area or on a
mounting plate for mounting in an ARINC 408A 3ATI round instrument panel space.
The PTM is conduction, radiation, and natural convection cooled. It does not require any
external cooling as long as it is installed in a pressurized area where the ambient
temperature is within the established temperature range of the device.
