An apparatus for detecting incursions for an aircraft and surface vehicles includes an incursion processor receiving ownship position from an ownship navigation processor, traffic information from a traffic surveillance processor, and obstacle information from an obstacle detector and generating alert information. The apparatus also includes a display processor receiving airport chart information and providing display information for displaying the alert information and airport chart information.

Runway and airport incursion alerting system and method

A method of communicating an uncertainty of a location of an object near an aircraft is disclosed. According to the method, a plurality of signals are received from positioning sources. Each of the positioning sources provide information regarding the location of the object. A positional uncertainty of the object is obtained for each of the plurality of signals. Each positional uncertainty is related to an accuracy of the signal to which the respective positional uncertainty relates. The obtained positional uncertainties are combined to derive a combined positional uncertainty of the object having first and second mutually orthogonal directional components. The combined positional uncertainty is expressed as a geometric shape. On a display associated with the aircraft upon which the aircraft and the object are graphically represented, the geometric shape is superimposed on the graphical representation of the object, to thereby apprise a viewer of the positional uncertainty of the object.
