When the aircraft is in the air and a destination waypoint has been entered, the fuel calculations can be 

completed.

• Estimated landing weight = zero fuel weight + estimated landing fuel weight.

• Estimated landing fuel weight = fuel on board weight - (fuel flow x ETE) 

• Excess fuel weight = estimated landing fuel weight - fuel reserves weight

If the aircraft is on the ground or a destination waypoint has not been entered, the following fields display 

invalid values consisting of six dashes:

• Estimated landing weight

• Estimated landing fuel weight

• Excess fuel weight

If the zero fuel weight is greater than the maximum allowable zero fuel weight, then the zero fuel weight is 

displayed in amber.

If the aircraft weight is greater than the maximum allowable takeoff weight, then the aircraft weight is displayed 

in amber.

If the estimated landing weight is greater than the maximum allowable landing weight, then the estimated 

landing weight is displayed in amber.

If the estimated landing fuel weight is positive, but less than or equal to the fuel reserves weight, the following

values are displayed in amber:

• Estimated fuel at landing weight

• Excess fuel weight

If the estimated landing fuel weight is zero or negative, then the following values are displayed in red:

• Estimated fuel at landing weight

• Excess fuel weight
