CMA-9000 FLIGHT MANAGEMENT SYSTEM
SYSTEM ALERT
MESSAGE
DESCRIPTION
ACTION
PRED SPEED LIMITED
The FMS identifies a speed constraint
(crew entered or derived from the
navigation database) that is not within
the performance database speed entry
limits.
Review the speed/altitude restrictions and
segment or waypoint altitude/speed constraints
and modify accordingly. If no change is made,
then do not use the FMS for VNAV.
POLICY FILE INVALID
The FMS detects an invalid Policy File
(bad CRC).
The FMS VNAV function can not be used.
Once on ground, reload the Airline policy file.
POSITION SHIFT
While LNAV is engaged, the FMS
transitions from one navigation mode
(position fixing mode) to another thus
inducing a position jump larger than
1nm.
In such case the FMS reduces its
lateral path capture angle from 45
degrees (default value) to 25 degrees.
Crew to monitor that the aircraft smoothly
recaptures the lateral flight plan.
ROUTE CORRUPTION
Current route is corrupted. Reload route from Custom Route Database.
RWY/ILS MISMATCH
RWY/MLS MISMATCH
An ILS, LOC, LOC BC or MLS
approach is selected in the active flight
plan;
and
The manually-tuned ILS frequency or
MLS channel does not match the
frequency/channel of the ILS, LOC or
MLS station associated with the
selected approach.
Check that the selected approach is correct.
Check that the manually tuned frequency ILS is
correct.
SET AUTO SPEED
FMS transitioned from Climb to Cruise
or from Cruise to Descent and FGCP
speed intervention is active.
Activate AUTO SPEED on the FGCP panel to
set control of the AFCS speed target to the
FMS.
T/C AFTER T/D – NO
CRZ
When the computed vertical profile
leads to no cruise and descent paths
and the CRZ ALTITUDE LOWER
message has not been raised
Verify the lateral and/or vertical flight plan and
correct accordingly.
If no changes are made, the message will be
removed upon levelling off at the cruise altitude
where a cruise and descent profile will be
calculated.
SWS INPUT LOST
Loss of communication with both SWS.
Advise maintenance
T/O DATA DELETED
After at least one takeoff speed (V1, VR,
V2) has been entered while on ground, if
the crew changes one of the following
items:
ZFW, Block Fuel Weight, Taxi Fuel
Weight, Departure Runway, Flex and
Derate.
Re-enter takeoff speeds that are consistent with
the new parameter(s) which led to the deletion
of the takeoff speeds.
