1. Apparatus for the predictive display of the navigation characteristics of craft relative to at least first and second way points of a confined navigation channel with respect to time, at least one of said way points being characterized as a locality within which it is hazardous for craft to pass one another, comprising:
- fixed location sensor means for generating coordinate and velocity component data of craft with respect to said fixed location sensor means,computing means responsive to said coordinate and velocity component data for computing the predicted distance of travel of at least a first of said craft along said confined navigation channel with respect to said way points at a predetermined future time, anddisplay means responsive to said computing means for displaying, in distance of travel and time coordinates, the present and predicted distance of travel and the corresponding present and future time coordinates of said first craft as first and second time-distance points on said display.

5. The method of predictive display of navigation characteristics of craft relative to at least first and second way points of a confined navigation channel with respect to time, at least one of said way points being characterized as a locality within which it is hazardous for craft to pass one another, including the steps of:
-
generating coordinate and velocity component data of craft with respect to fixed location sensor means, employing said coordinate and velocity component data for computing the predicted distance of travel of at least a first of said craft along said confined navigation channel with respect to said way points at a predetermined future time, and displaying, in distance of travel and time coordinates, the present and predicted distance of travel and the corresponding present and future time coordinates of said first craft as first and second time-distance points on said display. - View Dependent Claims (6, 7, 8, 9, 10, 11, 12, 13)
