The DAFCS system provides fail-operational
execution of flight director guidance, autopi-
lot, yaw damper, and trim functions. The flight
guidance computers (FGC) generate auto-
matic flight path commands and use attitude
and direction from the IRS and FMS, air data
from the DADC, and displays from the EFIS
and MFD for aircraft autopilot control. The au-
topilot and associated functions provide sta-
bilization and control needed to ensure the
best performance throughout the aircraft flight
profile.
An avionics standard communications bus
(ASCB) provides the communication hub for
the DAFCS computers to share information.
Each of the following systems directly inter-
face with the ASCB (Figure 16-19):
• AFCS
• IRS
• DADS
• FMS
• EFIS
• MFD
