E. TCAS Control Panel Provisions
Mechanical installation data for a typical Gables GXXXX Series ATC/TCAS control panel
is shown in Figure 2--14.
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.
F. TAWS/RWS Control Panel Provisions
The TAWS controls can be mounted on a single control panel or they can be discrete
switches individually mounted at a convenient location in the Flight Deck. The TAWS
controls may be part of the electronic display menu selection in installations where TAWS
information is displayed on an EFIS or electronic display.
Figure 2--1 shows the ACSS King Air C90 TAWS control panel/glareshield switch
annunciator installation design. The TERR and WXR select switches shown are
momentary but alternate action switches are also supported. The terrain INHIBIT or
OVRD switches are alternate action switches and are typically gaurded.
The T

CAS TAWS control/annunciator installation design will vary depending on the Flight
deck configuration and available space.
G. VSI/TRA Provisions
Mechanical installation data for the VSI/TRA display is shown in Figure 2-- 15. The
VSI/TRA is usually used as a direct replacement for the existing 3-- ATI form VSI indicator
currently mounted in the Flight Deck. 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 Thales 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, a static line can be run directly
into the Thales VSI/TRA from a static pneumatic input.
H. TAWS Terrain Hazard Display Provi sions
ARINC 708A and ARINC 429 WXR display and EFIS interfaces are supported. T

CAS’
dual -- independent terrain hazard display I/O supports dual ARINC 708A and dual ARINC
429 terrain hazard display systems. Figure 2--2 shows TAWS Dual Terrain hazard display
annunciator switch panels and locations that have been used on B757, B767, and
B737--300/400/500 aircraft. Figure 2--3 shows a typical single terrain hazard display
annunciator switch panel.
