A system and method are provided that improve upon existing aircraft display systems by generating and updating an overrun image that may be overlaid on a variety of panoramic and landscape images on a display device. The overrun image displays stopping locations for all relevant available stopping devices, as determined from the far end of the selected runway. In addition, the aircraft display system determines an advisory zone on the selected runway and presents limited symbols and images in and near the advisory zone that indicate distances and relevant information.

1. A display system for an aircraft, comprising: a display device; anda computer coupled to the display device, the computer comprising a processor and a computer readable storage medium, the computer configured to: receive, from a navigation system, an aircraft position and location;receive, from a sensor system, aircraft status data including, heading, altitude, and attitude, airspeed, vertical speed, remaining fuel, faults, conditions, thrust level, and aircraft configuration;determine, based on the aircraft status data and the aircraft position and location, (a) an aircraft energy state, and (b) a braking status of the aircraft, wherein the braking status is one of (i) maximum manual braking, (ii) thrust reverser only braking, (iii) maximum manual braking with thrust reverser braking, (iv) auto-brake high, (v) auto-brake medium, or (vi) auto-brake low;determine a predetermined length measured from a far end of the runway, defined as an advisory zone;andwhen the braking status is auto-brake high, determine a stopping location;when the braking status is not auto-brake high, determine a stopping location for maximum manual braking and a stopping location for the braking status;determine a distance remaining to the far end of the runway;determine whether the aircraft is on the ground; andwhen the aircraft is on the ground, determine a current deceleration stopping location; andcommand the display device; andwherein the display device is responsive to commands from the computer and configured to: overlay an overrun image on a displayed image,the overrun image having therein symbology representing a runway segment, the runway segment having thereon rendered,in a visually distinct manner with respect to a remainder of the runway segment, the advisory zone;for each stopping location, overlay the runway segment with a unique symbol representative thereof;display, within the overrun image, the distance remaining anda surface condition;and when the aircraft is not on the ground, overlay on the runway segment, a symbol indicating (i) a predicted touchdown point, and (ii) a long landing threshold line, defined as a maximum touchdown point;and when the aircraft is on the ground,(i) remove the symbol indicating the predicted touchdown point and the symbol indicating the maximum touchdown point, and (ii) display a symbol indicating the current deceleration stopping location. 2. The display system of claim 1, wherein the computer is further configured to overlay the advisory zone with a number of indicator symbols arranged at equally spaced intervals within the advisory zone, wherein the number is less than six. 3. The display system of claim 1 wherein the computer is further configured to: change a color of the runway segment when the aircraft is predicted to be unable to stop by the far end of the runway. 4. The display system of claim 1 further comprising an audio system configured to receive commands from the computer and emit sounds and speech responsive thereto, and wherein the computer system is further configured to: command the audio system to emit an aural alert when it is determined that the aircraft is predicted to be unable to stop before reaching the far end of the runway. 5. The display system of claim 1, wherein the computer is further configured to receive a predetermined threshold safety distance, and render a border of the runway and the indicator symbols in a first color, responsive to determining that the stopping location associated with the braking status of the aircraft exceeds the predetermined threshold safety distance. 6. The display system of claim 5, wherein the computer is further configured to change a color used for rendering the border of the runway and the indicator symbols, responsive to determining that the stopping location associated with the braking status of the aircraft is prior to the predetermined threshold safety distance. 7. A method for a display system onboard an aircraft, the method comprising: at a computer, receiving, from a navigation system, an aircraft position and location;receiving, from a sensor system, aircraft status data including, heading, altitude, and attitude, airspeed, vertical speed, remaining fuel, faults, conditions, thrust level, and aircraft configuration;determining a length measured from a far end of the runway, defined as an advisory zone;determining a distance remaining to the far end of the runway;determining, based on the aircraft status data and the aircraft position and location, (a) an aircraft energy state, and (b) a braking status of the aircraft, wherein the braking status is one of (i) maximum manual braking, (ii) thrust reverser only braking, (iii) maximum manual braking with thrust reverser braking, (iv) auto-brake high, (v) auto-brake medium, or (vi) and auto-brake low;andwhen the braking status is auto-brake high, determining a stopping location;when the braking status is not auto-brake high, determining a stopping location for maximum manual braking and a stopping location for the braking status;determining whether the aircraft is on the ground; andgenerating commands for a display device; andon a display device, responsive to commands from the computer system,overlaying an overrun image in a dedicated area of a displayed image;the overrun image having therein symbology representing a runway segment, the runway segment having thereon rendered, in a visually distinct manner with respect to a remainder of the runway segment, the advisory zone;for each stopping location, overlaying the runway segment with a unique symbol representative thereof;displaying, within the overrun image, the distance remaining; anda surface condition of the runway; andwhen the aircraft is not on the ground, overlaying on the runway segment a symbol indicating (i) a predicted touchdown point, and (ii) a long landing threshold line, defined as a maximum touchdown point; andwhen the aircraft is on the ground, determining a current deceleration stopping location, andcommanding the display system to (i) remove the symbol indicating the predicted touchdown point and the symbol indicating the maximum touchdown point, and (ii) display a symbol indicating the current deceleration stopping location. 8. The method of claim 7, wherein the advisory zone is substantially a final third of the runway and the display system is further configured to overlay 3 indicator symbols arranged at equally spaced intervals in the advisory zone.
