Classification: CPC B  G | IPC B  G

Claim 11:
12. A method for providing time-based overlays for positional maps, the method comprising:
providing, via an aircraft-based flight display system, a distance-based moving map comprising:
a current position of an ownship;
a velocity vector of the ownship;
and

one or more time-displaced objects including at least one of
1) a time-displaced mobile object moving relative to the ownship or
2) a time-displaced fixed object associated with a flight plan under execution by the ownship;
determining, via the flight display system, at least one time range of the ownship, the at least one time range based on the velocity vector and indicative of a time-displaced position of the ownship corresponding to a subsequent time;
determining, via the flight display system, at least one of 1) a relative velocity associated with each time-displaced mobile object or 2) a predicted arrival time associated with each time-displaced fixed object;
and
superimposing 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, each time-displacement vector based on the relative velocity or the predicted arrival time and including a terminator indicative 1) of a time-displaced contact of the ownship and the time-displaced object and 2) of a type of the time-displaced object.
