SYSTEM ALERT
MESSAGE
DESCRIPTION ACTION
APPLICABLE
CONFIGURA-TION
HEADING INPUT
LOST
Total loss of heading input.
When not in GPS navigation, the
FMS builds up an error during
rapid turns, and should be used
with caution. No wind
computation is available.
Refer to Operator’s Manual
Section 16 for operation with
a failed heading input.
AHRS interface
HF CONTROL
LOST
The FMS has detected a HF
radio failure
Ensure that HF radio is
powered.
Verify that the HF radio
operates normally.
Advise maintenance.
Installations in which the
HF radio is configured.
HIGH ARC EXIT
SPEED
The combination of current TAS
and computed wind may cause
the aircraft to overshoot the next
flight plan leg.
Reduce speed prior to exiting
the arc.
All configurations
HIGH GLIDEPATH
ANGLE
Computed glide-path angle for
the selected approach exceed
the maximum VPA allowed.
Check VPA displayed on
VNAV APPR page.
If VPA is appropriate conduct
approach normal.
If VPA is not appropriate stop
using the FMS for advisory
VNAV of this approach and
report issue to maintenance
operations.
VNAV configuration
HIGH HOLDING
SPEED
The combination of current TAS
and computed wind may cause
the ICAO holding pattern
protected airspace to be
exceeded. This message is
displayed one (1) minute prior to
reaching the holding fix and on
passage over the fix.
Reduce speed prior to
reaching the holding fix.
If the message is
configured.
HIGH SAR SPEED
The FMS detects that the ground
speed (e.g. combination of
current TAS and computed wind)
will cause the search and rescue
pattern to overshoot. This
message is displayed starting
from one (1) minute prior to
reaching the SAR entry point
until the SAR entry point is
reached. This message is only
displayed when airborne.
Reduce speed to make sure
that the search area is
covered.
SAR is configured.
IFF CONTROL
LOST
The FMS has detected an IFF
failure (CBIT) or it cannot tune
the IFF e.g. the requested tuning
does not match the feedback
received for 10 seconds when in
normal (non-maintenance) mode
of operation.
Ensure that IFF transponder
is powered.
Verify that the IFF
transponder operates
normally.
Advise maintenance.
Installations in which the
IFF transponder is
configured.
