OPERATOR’S MANUAL
CMA-9000 FLIGHT MANAGEMENT SYSTEM
TOGW [1L]:
GWT [1L]:
Displays one of the following:
• The predicted aircraft Takeoff Gross Weight (TOGW) when the aircraft is on-ground (prior to lift-off) and all
mandatory weight data was entered by the pilot.
• The TOGW corresponds to:
• ZFW [3L] + BLOCK fuel weight [2L] - TAXI fuel weight [5L]
OR
• The actual aircraft Gross Weight (GWT) when all mandatory weight data was entered by the pilot and the
aircraft becomes airborne.
• The GWT value is the sum of:
• ZFW [3L]; and
• FUEL weight [2L];
Manual entry of TOGW/GWT is not allowed.
Calculated TOGW/GWT value is displayed in small white font. The data field is blank when the ZFW or
BLOCK/FUEL fields display boxes.
BLOCK [2L]:
OR
FUEL [2L]:
OR
FUEL(EST) [2L]:
Entry and display of the fuel weight available in the aircraft. This value includes the RESERVES fuel weight.
This data field displays:
• the BLOCK fuel weight entered by the crew when on-ground; OR
• the actual FUEL weight received from the fuel computer (if available) when airborne; OR
• the FMS-estimated FUEL(EST) weight if no Fuel Weight is available from the Fuel Computer or a manual
fuel weight entry was performed when airborne.
When airborne, crew-entered fuel weight is decremented using actual Fuel Flow from the fuel computer if
available. If no Fuel Computer Fuel Flow data is available, then the FMS will update any manual fuel weight
entry using the PDB fuel flow tables.
When on-ground, crew-entered BLOCK fuel weight is not decremented.
Computed/received fuel weight is displayed in small white font. BLOCK fuel weight is displayed in large white
font if manually entered, otherwise boxes are displayed.
When a ZFW is displayed and:
• a manual BLOCK fuel weight entry is made, this results in the calculation and display of a TOGW value at
[1L] if the aircraft is on-ground.
• a valid FUEL weight is available, this results in the calculation and display of a GWT value at [1L] if the
aircraft is airborne.
FOB: Display of the fuel weight available in the aircraft as provided by the Fuel Quantity computer.
The 'FOB' title field is only displayed when the aircraft is on-ground. The associated data field is only displayed if
a valid Fuel Weight is being provided by the Fuel Quantity Computer and the aircraft is on-ground.
