1. A system for determining a stopping point of an aircraft on a runway during a landing on the runway or an aborted takeoff on the runway, the system comprising:
- a position sensing means for gathering data regarding incremental positions of the aircraft relative to the runway;
a calculating means for dynamically computing a projected stopping point of the aircraft based on the data regarding incremental positions of the aircraft relative to the runway gathered by the position sensing means; and
a display means located on the ground adjacent to the runway for communicating information representing the projected stopping point of the aircraft to a flight crew.

Abstract
A ground-based system for determining a stopping point of an aircraft on a runway includes a position sensing means for gathering data regarding incremental positions of the aircraft relative to the runway, a calculating means for dynamically computing the projected stopping point of the aircraft based on the data gathered by the position sensing means, and a display means located on the ground along the runway for communicating information representing the projected stopping point of the aircraft to a flight crew.

18. A method for predicting a stopping point of an aircraft on a runway during a landing on the runway or an aborted takeoff on the runway, the method comprising the steps of:
-
with an Automatic Dependent Surveillance-Broadcast system, gathering multiple data sets regarding an instantaneous position of the aircraft; transmitting the multiple data sets regarding an instantaneous position of the aircraft to a ground-based receiver; determining a location, velocity, and deceleration for the aircraft using the multiple data sets regarding an instantaneous position of the aircraft;
dynamically calculating a projected stopping point for the aircraft based on the determined location, velocity, and deceleration for the aircraft; andcommunicating the projected stopping point to a flight crew of the aircraft by a ground based display located adjacent to the runway. - View Dependent Claims (19)

20. The method according to dam 18, further comprising the step of:
-
determining whether the aircraft has touched down on the runway prior to crossing a system activation line, the system activation line being a predetermined longitudinal point on the runway; and if the aircraft has not touched down on the runway prior to crossing the system activation line, at the ground based display, outputting a go-around visual indication; wherein the go-around visual indication indicates to the flight crew that the aircraft should not land on the runway.
