CONFIGURA-TION
DF CONTROL
LOST
The FMS has detected one of
the following conditions:
if a DF-430-102 is configured:
•
The FMS detects a DF radio
failure or it cannot tune the DF
radio (requested tuning does
not match feedback for 10
seconds).
if a DF-935 is configured:
The following conditions are
detected during a period of 10
seconds:
•
The command echo is not
received from the Direction
Finder equipment (DF); or

Advise maintenance
.
DF-430-102 or
DF-935 interface
DF INPUT LOST
The FMS has detected a failure
or a loss of communication from
the DF radio.
Ensure that DF is powered.
Verify if the DF operates
normally.
Advise maintenance.
DF 430-112 interface
DIRECT TO FIX
When flying a VI or CI leg
followed by a CF leg (these legs
being part of a published
procedure), the FMS detects that
the predicted intercept point is
so close to the CF leg
termination that the intercept
path cannot be calculated.
Review the intercept course
entered.
All configurations
DISCONTINUITY
AHEAD
60 seconds before the end of the
active leg or at the beginning of
the active leg when its duration
is shorter than 60 seconds, and
the FMS detects that the next
waypoint is followed by a
discontinuity.
The message remains displayed
as long as the FMS flies into the
route discontinuity.
NOTE: The FMS will invalidate
its roll command output when
reaching the discontinuity.
Select RTE LEGS page to
enter next waypoint or close
up route discontinuity.
All configurations
DMAP INPUT LOST
The FMS detects a total loss of
DMAP input data on the onside
and offside FMSs.
Ensure that DMAP is
powered.
Verify if the DMAP operates
normally.
Advise maintenance.
