OPERATOR’S MANUAL
CMA-9000 FLIGHT MANAGEMENT SYSTEM
ZFW [3L]: Entry and display of the aircraft Zero Fuel Weight (ZFW).
Manual entry is only allowed when the aircraft is on ground. Valid manual entry format is NN.N metric tons, as
defined in the PDB. Deletion of the ZFW is not allowed, trying to do so results in displaying the previously
displayed data.
Manual entry is displayed in large white font.
RESERVES [4L]: Entry and display of the Reserves fuel required at the destination airport.
RESERVES Field is a mandatory entry (i.e. boxes displayed). If no default Fuel Reserves weight is defined in
the Policy File. Otherwise, the Reserves fuel weight defined in the Policy file is the default RESERVES fuel
weight displayed on this page and only a manual entry will override this default value. Deletion of the manual
entry reverts to the default RESERVES value if such a value is defined in the Policy File. Valid manual entry
format is N.N or NN.N metric tons, as defined in the PDB.
Manual entry is displayed in large white font. Default value is displayed in small white font if applicable.
NOTE: The actual aircraft RESERVES fuel weight is included in the FUEL/BLOCK weight.
TAXI [5L]: Entry and display of the predicted TAXI fuel weight available in the aircraft. TAXI fuel will only be
displayed/enterable when the aircraft is on-ground.
TAXI fuel weight can be a default (Policy File defined) or a manually entered value. Deletion of the TAXI fuel
weight reverts to the Policy File defined default TAXI fuel weight.
A default Taxi fuel weight value is displayed in small white font and a manually entered value is displayed in
large white font.
INIT/REF [6L]:
ERASE [6L]:
"INIT/REF" is displayed when there is no active flight plan modification in progress. Pressing the LSK provides
direct access to INIT/REF INDEX 1/2 page.
"ERASE" is displayed when an active flight plan modification is in progress. Pressing this key will undo all
changes to the active flight plan and return to the ACT Route status.
CRZ ALT [1R]: Entry and display of the cruise altitude (MCDU entry or derived from the Selected Altitude. The
value entered is propagated between the PERF INIT, CLB, CRZ and Engine Out pages.
CRZ ALT can be a manual entry or a change in the Selected Altitude. Valid manual entry format is: XXX (flight
level), FLXXX or XXXXX (feet). The minimum altitude that can be entered is the greater of the minimum default
value or the elevation of the departure runway. The maximum altitude that can be entered is defined in the PDB.
Deletion of the cruise altitude is allowed.
In climb, the FMS accepts the Selected Altitude change in the data field only if it is higher than the CRZ ALT of
the active route; otherwise, there is no effect on the data field.
In cruise, the FMS accepts the Selected Altitude change (higher or lower value than current CRZ ALT value) in
the data field at any time, except when the aircraft is within 50 nautical miles before the top-of-descent, at which
time a change has no effect on the data field.
In descent, a change of the Selected Altitude has no effect on the data field.
The CRZ ALT value is displayed in large white font. When no cruise altitude has been entered or the data field
has been deleted, the data line displays boxes.
While airborne, if all the weight-related data fields (GWT and ZFW) contain data and the CRZ ALT data field is
empty, the current airplane altitude is copied in small white font in the CRZ ALT data field when the EXEC is
pressed.
CRZ TEMP [2R]: Entry and display of the Cruise Temperature.
Valid range for Cruise Temperature is between -75
°
C and +55
°
C.
Manual entry of the Cruise Temperature is displayed in large white font. Default Cruise temperature
corresponds to the to the predetermined ISA temperature for the selected Cruise Altitude and is displayed in
small white font. Deletion of the manual entry is allowed and will revert to the default Cruise temperature.
