1. A system for displaying differential ground speed for traffic surrounding an aircraft, comprising:
an aircraft control panel in a cockpit of an ownship aircraft; and
a digital traffic display for providing cockpit display of traffic information (CDTI), where the digital traffic display is located on the control panel and shows,
a speed scale that shows a graphical display of ground speed of the ownship aircraft and ground speed of traffic to follow (TTF),
a separation scale that shows a graphical display of a separation distance between the ownship aircraft and the TTF, where the separation scale is graphically co-located with the speed scale and where a change in the separation distance is calculated based on the ground speed difference between the ownship aircraft and the TTF over a pre-determined time period, and
an advisory/warning indicator that shows a color-coded status of a predicted change in separation distance in comparison a pre-determined desired separation distance between the ownship aircraft and the TTF.
