EICAS Failure Message
-- CHK EICAS is displayed to indicate that
the EICAS wrap--around monitor has detected a difference between
what EICAS is displayed and what the DAUs have sent to the EICAS
for display.
D
Heading Failure and Flags
-- Failure of the displayed heading from
the AHRS is shown by removing the flight plan from the display. The
digital heading readout is replaced by amber dashes. As shown in
figure 4--42, a red HDG FAIL label is displayed below the lubber line.
NOTE:
When the EFIS test is selected, HDG FAIL is replaced
with HDG TEST.
D
MADC Failures
-- MADC failures are indicated by replacing the
TAS, SAT, and TAT numerical values with amber dashes.
D
FMS Failures
-- A failure of the FMS removes the active lateral flight
plan waypoints, navaids, and airports from the display. This
indication is also given in the event of an invalid heading display.
