(ACARS msg)
II/A The aircraft is at 180 nm from destination and the destination
QNH, TEMP or WIND displayed on the PERF APPR page
received by ACARS uplink has to be checked.
If a modification of these parameters is performed creating a
conflict with previous data, the message is triggered again.
CHECK FLT NBR
(ACARS msg)
II/A The uplinked flight number differs from the flight number specified
in the request.
CHECK GW II/A The gross weights computed by the flight management computer
and the flight augmentation computer disagree by more than 7 t
(7.7 U.S tons)
CHECK QFE II/A This appears at the transition from QNH to QFE reference, when
the QFE altitude differs by more than 100 ft from the predicted
altitude, with the QNH set on the MCDU by means of the airport
elevation in the NAV database.
CHECK TAKEOFF DATA II/W The flight crew changed the runway on the origin airport, entered
or modified the T.O. shift, FLEX T.O. temperature or derated
level (if option installed) after V1, V2, VR insertion, activated
the secondary in PREFLIGHT or DONE phase, or changed the
takeoff runway.
CLK IS TAKEOFF TIME II/W This appears when the flight crew has entered an Estimated
Takeoff Time (ETT), and the actual time is equal to ETT.
CLOCK/GPS TIME DIFF XX II/A Aircraft clock time and GPS time differ by more than XX minutes.
CROSSLOAD ABORTED II/W Message displayed on the transmitting MCDU, indicating an error
in the transmission process.
CROSSLOAD COMPLETE II/W The database crossload from one FMGC to the other was
successfully completed.
CRZ FL ABOVE MAX FL II/W This appears when the flight crew enters a cruise altitude that is
above the computed maximum altitude.

Continued from previous page
MESSAGE TYPE/COLOR CONDITIONS
CSTR DEL ABOVE CRZ FL II/W This appears when a flight plan altitude constraint has been
deleted because the flight crew has inserted a cruise flight level,
or step-down altitude that is at or below the flight plan constraint.
CSTR DEL UP TO WPT01 II/W This appears when constraints get deleted because the aircraft
transitions to a go-around flight phase, before the FMGS
sequences the flight plan destination.
DECELERATE
Also displayed on PFD
II/A The aircraft is still in the cruise phase and managed speed, after it
reaches the Top of Descent and has not begun the descent.
DELETING OFFSET II/W This appears when the system is deleting an offset automatically,
which it does under certain specific conditions, such as :
change of active leg ‐ due to lateral revision.
‐ termination of next leg at destination runway and the current
distance to go is less than or equal to the distance required to
reach the path, or the next leg is not a CF, FM or TF leg.
DEST/ALTN MISMATCH I/W The pilot attempts to enter an alternate CO RTE (which starts at
an origin that is not the primary flight plan destination).
DIR TO IN PROCESS I/W The flight crew calls up the vertical or lateral revision page on one
MCDU while the direct to page is displayed on the other MCDU.
ENTER DEST DATA II/A The flight crew has not entered wind, QNH, or temperature for the
destination, and the aircraft is 180 nm out.
ENTRY OUT OF RANGE I/W The flight crew attempts to enter data that is out of the range
specified for the selected field.
FLT NBR UPLINK
(ACARS msg)
II/W A flight number has been added to the uplink flight plan without
previous request.
F-PLN ELEMENT RETAINED I/W The flight crew attempts to delete stored navaids, waypoints or
runways that are contained in any flight plan or that are being
tuned.
F-PLN FULL II/W There is not enough memory in the flight plan allotment for the
computer to accept more flight plan data.
FMS1/FMS2 A/C STS DIFF II/W This message always precedes a transition to independent mode,
and appears at power-up if the system detects a difference in one
of the following :
NAV ‐ database serial number
‐ Performance database
‐ FM operational program
‐ Aircraft and airline program pins
FMS1/FMS2 GW DIFF II/W Onside and offside aircraft weight differ by 2 t or more.
FMS1/FMS2 PGM PIN DIFF II/W Onside and offside program pins are different.
FMS1/FMS2 POS DIFF II/A Onside and offside positions differ by 0.5 nm or more.
FMS1/FMS2 SPD TGT DIFF II/W Onside and offside target speeds differ by 5 kt or more.
