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.
