B. (4) Fault Warning Computers
(FWC)
The GIV system contains two fault warning computers. The FWC
provides all the messages to the SGS for display on the CAS format.
Each
FWC is doing the same computations on aircraft system inputs.
Only one FWC is displayed at a time, making the other a hot spare.
(5) Data Acquisition Unit (DAU)
The GIV
system contains two data acquisition units. The DAUS
provide all the aircraft engine information
in addition to the
analog data of some subsystem parameters to the SG for display on
the ENGINE display.
DAU 1 provides left engine data and DAU 2
provides right engine data.
(6) Display Dimming Panel
One display dimming panel has been incorporated into the GIV system
for the purpose of adjusting the brightness of the six display
units.
(7) Display Power Panel
In addition to the circuit breaker panel, power may be removed from
the display system by the display power panel located in the
overhead on the pilot’s side of the cockpit. This panel is shown in
Figure 202.
