FC-880 Fault Warning Computer
Leading Particulars
Table 6-9
The FC-880 Fault Warning Computer (FWC)
is a digital
computer
primarily
responsible
for supplying data to the symbol generators for display of
warnings, advisories, and aircraft system status information on the EICAS
displays. The FWC receives data directly from aircraft systems and over
the ASCB from the data acquisition units, symbol generators, display
controller, digital air data computers, priority flight guidance
computer, and from the FMS. Specific discretes for cockpit annunciators
or horns are outputs of the FWC.
Information displayed on the crew alerting system (CAS) display portion
of the EICAS display is received, logically organized, placed through
system algorithms, and transmitted from the FWC to the symbol generators
over the ASCB.
Both channels of each DA-884 Data Acquisition Unit are monitored by both
FWCS with errors between the two channels being annunciated on the CAS
display. The DC-884 Display Controller contains the selection
capabilities for the pilot to select the appropriate FWC to be utilized
by the display system.
The FWC
contains
a user-accessible
checklist
module.
This
module
has the
capability
to store
64k bytes
of text data
for the checklist and
emergency checklist system pages. The actual contents of the module is
user-defined.
The FWC monitors various subsystem status and discretes to determine when
the display and FGC can achieve a Category 11 approach. The logic is
continuously monitored. Status is reflected on the PFD and EICAS as
determined by the FWC.
