SYSTEM ALERT
MESSAGE
DESCRIPTION
ACTION
DIRECT TO FIX
When flying a Heading-to-Intercept
from a published procedure, the
predicted intercept point is so close to
the next leg termination that the
intercept path cannot be calculated.
NOTE: The FMS then calculates a
path direct to the next leg
termination (waypoint).
Monitor FMS guidance.
DISCONTINUITY AHEAD
The next waypoint (following the active
leg) is a discontinuity.
The message is reinstated 60 seconds
before the discontinuity becomes active,
if the condition remains.
Access RTE LEGS page to enter next waypoint
or to close up route discontinuity. Failure to
remove the discontinuity before it becomes
active will cause FMS steering to become
invalid.
DME/DME NAV LOST
DME-DME navigation no longer
available due to receiver(s) failure.
If FMS was in DME-DME navigation
mode, it automatically reverts to the next
available navigation mode.
Verify if identified DME transceiver(s) operate(s)
normally.
Use another navigation sensor as a means of
primary navigation.
Advise maintenance.
DME CONTROL LOST
DME1 CONTROL LOST
DME2 CONTROL LOST
The FMS cannot control the DME which
is paired with the NAV radio. or
Failure of the DME channel associated
with NAV radio (manual tuning).
Control DME from another source.
DME receiver is no longer operational, use
other navigation aids.
Advise maintenance.
END OF ROUTE
Passing the last waypoint in the route.
FMS steering becomes invalid.
Select RTE LEGS page to enter additional
waypoints to resume FMS steering.
ENGINE OUT
The FMS has detected an engine out
condition.
Manage the aircraft operational parameters.
Engine Out VNAV is supported during Climb or
Cruise (ENGINE OUT (5R) on the CRZ page).
Do not use VNAV mode during Descent.
ENTER POS/DATE/TIME
Battery failure invalidating the RTC
date/time and current position.
Master Caution is active.
Enter date, time and position.
Advise maintenance.
ENTER FORECAST
QNH
Aircraft is within 25 nm of the T/D (or
past the T/D) and no Destination airport
QNH/QFE entry was performed on both
the altimeter and the FMS.
Enter QNH/QFE on the DESCENT
FORECAST 1/2 page.
FMS ALTITUDES
DISAGREE
Excessive difference between two
baro-corrected altitude inputs, two
FMS-calculated baro-corrected
altitudes or two pressure altitude
inputs.
Verify altimeter setting on all systems
FMS DEGRADED
Internal FMS hardware fault related to
I/O interface. The fault prevents full
function of the FMS. This fault is not
critical to the operation of the FMS user
interface or processing.
Master Caution is active.
Continue to use the FMS user interface.
Backup systems will takeover the affected
operations. Refer to MAINT MESSAGE page
for fault trouble shooting.
Advise maintenance.
