1. A flight display system for providing time-based overlays for a positional map display, the flight display system comprising:
one or more graphics processors coupled to controlling avionics of an aircraft, the controlling avionics including a memory configured for storage of a flight plan under execution by the aircraft;
at least one display unit configured for display of a distance-based moving map comprising:
a current position of the aircraft at a current time;
a velocity vector of the aircraft; and
one or more time-displaced objects including at least one of:
a time-displaced mobile object traveling relative to the aircraft;
or
a time-displaced fixed object associated with the flight plan;
wherein the flight display system is configured to:
determine at least one time range of the aircraft based on the velocity vector, each time range indicative of a time-displaced position of the aircraft at a subsequent time;
determine a relative velocity associated with each time-displaced mobile object;
determine a predicted arrival time associated with each time-displaced fixed object;
and
superimpose on the distance-based moving map;
a time-domain range indicator based on the at least one time range;
and
a time-displacement vector corresponding to each time-displaced object and indicative of a time-displaced contact of the aircraft and the time-displaced object, the time-displacement vector based on the relative velocity or the predicted arrival time, the time-displacement vector including a terminator corresponding to the time-displaced contact and indicative of a type of the time-displaced object.
