1. A display system for an aircraft, comprising:
- a display device; and
a processor in operable communication with the display device and configured to receive at least data representative of estimated position uncertainty (EPU) for the aircraft, and traffic data associated with a traffic entity, the traffic data including at least data representative of EPU for the traffic entity, the processor further configured, in response to at least these data, to at least selectively render an image on the display device that includes;
(i) an aircraft symbol representative of the aircraft,(ii) an EPU graphic representative of the EPU for the aircraft, the EPU graphic encircling the aircraft symbol and having a radius proportional to the EPU for the aircraft,(iii) a traffic entity symbol representative of the traffic entity, the traffic entity symbol rendered at a position that is representative of traffic entity position relative to the aircraft, and(ii) a traffic entity EPU graphic representative of the EPU for the traffic entity, the traffic entity EPU graphic encircling the traffic entity symbol and having a radius proportional to the EPU for the traffic entity.

Abstract
An aircraft display system is provided for rendering at least aircraft estimated position uncertainty (EPU) and/or vertical estimated position uncertainty (VEPU) values non-numerically and in a fairly intuitive manner. The system may also render the EPU and VEPU values non-numerically for other traffic entities within range of the aircraft.

14. A display system for an aircraft, comprising:
-
a display device; and a processor in operable communication with the display device and configured to receive at least data representative of estimated position uncertainty (EPU) for the aircraft, and data representative of vertical estimated position uncertainty (VEPU) for the aircraft, the processor further configured, in response to at least these data, to at least selectively render an image on the display device that includes; (i) a side view aircraft symbol representative of a side view of the aircraft, and (ii) a navigation position uncertainty graphic representative of both the EPU and the VEPU for the aircraft, the navigation position uncertainty graphic surrounding the side-view aircraft symbol and having dimensions proportional to the EPU and the VEPU for the aircraft.

15. A display system for an aircraft, comprising:
-
a display device; and a processor in operable communication with the display device and configured to receive at least data representative of sensed aircraft altitude, and data representative of vertical estimated position uncertainty (VEPU) for the aircraft, the processor further configured, in response to at least these data, to at least selectively render an image of an altitude tape on the display device, the rendered altitude tape comprising; (i) an aircraft altitude graphic representative of the sensed aircraft altitude, and (ii) a VEPU marker, the VEPU marker comprising a first line segment disposed vertically above the aircraft altitude graphic, and a second line segment disposed vertically below the aircraft altitude graphic, the first and second line segments separated from each other by a vertical separation distance that is proportion to the VEPU for the aircraft.
