A system and method are disclosed for indicating to an aircrew of an aircraft a normalized runway icon to ensure visualization of a predicted touchdown point, runway length, stopping distance, energy state marking, and threat conditions, where normalization is referenced to typically available length for landing. Indications of present aircraft locations relative to the icons as well as alerts when thresholds are exceeded are provided.

1. A system for assisting a pilot of an aircraft to perform a stable landing, the system comprising: a processor configured to: determine an aircraft energy state of the aircraft; anda display responsive to the processor and configured to: display a first symbol resembling a runway;display a second symbol indicating a length of the runway or runway length remaining;display a third symbol associated with the first symbol indicating where the aircraft would touch down when landing at the aircraft energy state determined by the processor;display a fourth symbol having a first format and associated with the first symbol indicating where the aircraft would be able to stop based on the aircraft energy state and assumed braking performance;change the fourth symbol to a second format when the fourth symbol is at an end of the runway; andif the aircraft is on the ground, display a fifth symbol associated with the first symbol indicating the current location of the aircraft on the runway; anddisplay a sixth symbol associated with the first symbol indicating where the aircraft would be able to stop based on the aircraft energy state and current braking performance. 2. The system of claim 1 wherein the processor is further configured to: consider an airspeed, altitude, and distance to the runway of the aircraft when determining the aircraft energy state. 3. The system of claim 2 wherein the processor is further configured to: consider a configuration of the aircraft when determining the aircraft energy state. 4. The system of claim 1 wherein the processor is further configured to: change the fourth symbol to a third format when the aircraft would be unable to stop by the end of the runway. 5. The system of claim 1 further comprising an audio device, wherein the processor is further configured to: command the audio device to provide an audio alert that the aircraft would be unable to stop by the end of the runway. 6. The system of claim 1, wherein the processor is further configured to: determine which of the second, third, fourth, fifth, or sixth symbol is most critical to current aircraft operations, wherein the second, third, fourth, fifth, or sixth symbols occupy layers of the display; and wherein the display is further configured to: display the most critical symbol in the layer closest to the pilot. 7. A system for assisting a pilot of an aircraft to perform a stable landing, the system comprising: a database configured to store information about a runway including a length thereof;a processor coupled to the database and configured to: determine an aircraft energy state of the aircraft;determine a position of the aircraft in relation to the runway;determine a stopping distance of the aircraft when landing on the runway based on the aircraft energy state and assumed braking performance;determine a stopping distance of the aircraft when landing on the runway based on the aircraft energy state and current braking performance; anda display responsive to the processor and configured to: display a first symbol resembling the runway;display a second symbol indicating the length of the runway or runway length remaining;display a third symbol associated with the first symbol indicating where the aircraft would touch down when landing at the aircraft energy state determined by the processor;display a fourth symbol having a first format and associated with the first symbol indicating where the aircraft would be able to stop based on the aircraft energy state and assumed braking performance;display a fifth symbol associated with the first symbol indicating the current location of the aircraft on the runway;display a sixth symbol associated with the first symbol indicating where the aircraft would be able to stop based on the aircraft energy state and current braking performance; andchange the fourth symbol to a second format when the fourth symbol is at an end of the runway. 8. The system of claim 7 wherein the processor is further configured to: consider an airspeed, altitude, and distance to the runway of the aircraft when determining the aircraft energy state. 9. The system of claim 8 wherein the processor is further configured to: consider a configuration of the aircraft when determining the aircraft energy state. 10. The system of claim 7 wherein the processor is further configured to: change the fourth symbol to a third format when the aircraft would be unable to stop by the end of the runway. 11. The system of claim 7 further comprising an audio device, wherein the processor is further configured to: command the audio device to provide an audio alert that the aircraft would be unable to stop by the end of the runway. 12. A method for assisting a pilot of an aircraft to fly a stable landing, comprising: determining via a processor an aircraft energy state of the aircraft;displaying via a display a first symbol resembling a runway;displaying via the display a second symbol indicating a length of the runway or runway length remaining;displaying via the display a third symbol associated with the first symbol indicating where the aircraft would touch down when landing at the aircraft energy state;displaying via the display a fourth symbol having a first format and associated with the first symbol indicating where the aircraft would be able to stop based on the aircraft energy state and assumed braking performance;displaying via the display a fifth symbol associated with the first symbol indicating the current location of the aircraft on the runway;displaying via the display a sixth symbol associated with the first symbol indicating where the aircraft would be able to stop based on the aircraft energy state and current braking performance; andchanging via the processor the fourth symbol to a second format when the fourth symbol is at an end of the runway. 13. The method of claim 12 further comprising: considering via the processor the airspeed, altitude, and distance to the runway when determining the aircraft energy state. 14. The method of claim 13 further comprising: considering via the processor the configuration of the aircraft when determining the aircraft energy state. 15. The method of claim 12 further comprising: changing via the processor the fourth symbol to a third format when the aircraft would be unable to stop by the end of the runway. 16. The method of claim 12 further comprising: commanding via the processor an audio device to provide an audio alert that an approach of the aircraft is unstable exceeds a threshold related to the stopping distance of the aircraft. 17. The method of claim 12 further comprising: determining which of the second, third, fourth, fifth, or sixth symbol is most critical to current aircraft operations, wherein the second, third, fourth, fifth, or sixth symbols occupy layers of the display; anddisplaying the most critical symbol in the layer closest to the pilot.
