Zero Fuel Weight (Calculation Field) - Automatic calculation of all items
listed in the Payload (LB) section. The Zero Fuel Weight number will be
displayed in amber if the Zero Fuel Weight is greater than the maximum
allowable Zero Fuel Weight. See the gure below.
Figure 7-45 – Payload (LB) Section
FUEL (LB) ENTRY SECTION
The Payload (LB) section allows the crew to enter the weight of crew,
passengers, and cargo. Listed below are the elds listed in the Fuel (LB)
section with short denitions:
Zero Fuel Weight (Calculation Field) - This is the weight that is calculated in
the Payload (LB) section.
Fuel Onboard (Entry of Sync Field) - This eld is the total weight of the fuel
onboard the aircraft. The total weight of the fuel onboard can be manually
inserted by the crew. On power up, the Fuel Onboard displays the total fuel
quantity as referenced to the aircraft fuel quantity indicators. To sync the
fuel totalizer to this eld, press the FOB SYNC soft key on the bottom of
the MFD.
Aircraft Weight (Calculation Field) - The aircraft weight calculation is a total
weight of the zero fuel weight and fuel onboard.
Estimated Landing Weight (Calculation Field) - When the aircraft is in the
air and a destination way point has been entered, the fuel calculations
can be completed. Landing weight is automatically calculated based on
the following information: [ Estimated landing weight = zero fuel weight +
estimated landing fuel ]. If the estimated landing weight is greater than the
allowable landing or takeoff weight, then the estimated landing weight will
be displayed in amber.
NOTE: If the aircraft is on the ground or a destination way point has not
been entered, the following elds display invalid values consisting of six
dashes:
• Estimated landing weight
• Estimated landing fuel
• Excess fuel
