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.
