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
Weight Cautionaution And Warning Conditions
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

5.10 RAIM Prediction
RAIM (Receiver Autonomous Integrity Monitoring) is a GPS receiver function that performs a consistency check on all tracked satellites. RAIM ensures that the available satellite geometry allows the receiver to calculate a position within a specified RAIM protection limit (2.0 nm for oceanic, 2.0 nm for enroute, 1.0 nm for terminal, and 0.3 nm for non-precision approaches). During oceanic, enroute, and terminal phases of flight, RAIM is available nearly 100% of the time. The RAIM prediction function also indicates whether RAIM is available at a specified date and time. RAIM computations predict satellite coverage within ±15 min of the specified arrival date and time. Because of the tighter protection limit on approaches, there may be times when RAIM is not available. RAIM prediction must be initiated manually if there is concern over WAAS coverage at the destination or some other reason that compromises navigation precision. If RAIM is not predicted to be available for the final approach course, the approach does not become active. If RAIM is not available when crossing the FAF, the missed approach procedure must be flown.

Predicting RAIM availability at a selected waypoint:
1) Select the AUX-GPS Status Page.
2) Press the FMS Knob. The RAIM Prediction ‘WAYPOINT’ field is highlighted.
3) Turn the small FMS Knob to display the Waypoint Information Window. (Turning it clockwise displays a blank Waypoint Information Window, turning it counter-clockwise displays the Waypoint Information Window with a waypoint selection submenu allowing selection of active flight plan, nearest, recent, or airway waypoints).
