Time and fuel display
First Claim
1. A time and fuel display symbol for exhibition on a video display for providing a vehicle operator with a visual indication of time consumption and fuel consumption with respect to planned time and fuel consumption during travel of a vehicle over a planned route, said symbol comprising:
- a distance symbol a height of which is indicative of the total distance between a first location on said planned route and a second location on said planned route;
a distance traveled indicator located on said distance symbol, the position of said distance traveled indicator being indicative of a portion of said total distance traveled by said vehicle;
a time indicator located on said distance symbol, the position of said time indicator with respect to said distance traveled indicator being indicative of actual time consumption with respect to planned time consumption for said portion of said total distance traveled by said vehicle; and
a fuel indicator located on said distance symbol, the position of said fuel indicator with respect to said distance traveled indicator being indicative of actual fuel consumption with respect to planned fuel consumption for said portion of said total distance traveled by said vehicle.

Abstract
A mission computer (10) stores a nominal route plan which includes information indicative of the precise arrival time at specific navigation positions, e.g., waypoints, and the planned fuel consumption during travel to the specified waypoints. The mission computer (10) provides a time and fuel display system (15) with the route plan information. The time and fuel display system (15) generates a display (200) which indicates the total distance to be traveled during the mission (202), a distance traveled indicator (212) to reflect the progress of the aircraft along the mission, and a time bar (205) and a fuel bar (207) the height of which with respect to the indicator (212) are indicative of the percentage that the current time and fuel values are over or under the planned values for the current waypoint. The distance traveled indicator (212) is labeled with a waypoint designation (215) which is indicative of the designation of the waypoint towards which the aircraft is currently flying. A mission time display (220) and a fuel reserve display (223 ) provide a visual indication of the planned arrival time at the final destination and the planned fuel reserve upon arrival at the final destination. A Bingo fuel indicator (225) is provided to indicate the amount of fuel required to fly a direct route, at maximum range airspeed, to the mission end point with a planned fuel reserve.
