Abstract:
1. A system for monitoring an energy height of an aircraft during landing, comprising: a database including landing distance data; a processing unit configured to receive the landing distance data from the database and to calculate a landing distance of the aircraft based on a velocity and a height of the aircraft, the processing unit further configured to provide display signals based on the landing distance; and a visual display coupled to the processing unit and configured to provide a visual image based on the display signals, wherein the processing unit is configured to calculate the landing distance based on an energy height of the aircraft, and wherein the visual display displays an energy height monitor based on the energy height, the energy height monitor including an energy portion and an outline portion, wherein the energy height monitor selectively indicates a safe situation, an advisory situation, and an alert situation, wherein the safe situation indicates that the aircraft will land safely within a length of the runway, the advisory situation indicates that the aircraft will land within a safety margin portion of the runway, and the alert situation indicates that the aircraft will overrun the runway, wherein the outline portion represents a runway and the energy portion represents the energy height of the aircraft, the energy portion being superimposed on the outline portion to depict the energy height relative to the runway, wherein the energy portion displayed on the visual display during the safe situation and the advisory situation includes a landing portion and a safety portion.
