1. A computer-implemented method for providing in-flight traffic information corresponding to an aircraft and a traffic aircraft, comprising:

  • receiving at a traffic management computer, flight data associated with the traffic aircraft from the traffic aircraft;

    determining by the traffic management computer, flight data associated with the aircraft;

    utilizing by the traffic management computer, the flight data associated with the traffic aircraft and the flight data associated with the aircraft to determine characteristics of a single criteria indicator corresponding to both a longitudinal separation and a closure rate between the traffic aircraft and the aircraft, the characteristics of the single criteria indicator comprising line direction and length;

    providing by the traffic management computer, a plurality of altitude indication lines for display on a display unit of the aircraft;

    providing by the traffic management computer, an ownship representation on an altitude indication line determined from the flight data associated with the aircraft;

    providing by the traffic management computer, an aircraft traffic representation on an altitude indication line determined from the flight data associated with the traffic aircraft; and

    providing by the traffic management computer, the single criteria indicator for display on the display unit such that the characteristics of the single criteria indicator with respect to the ownship representation and the aircraft traffic representation indicates whether an altitude change of the aircraft through an altitude corresponding to the altitude indication line of the traffic aircraft is possible.
