Abstract
A device for rapidly obtaining data related to destination points in the form of a navigational chart that supports a slide to move in a defined path relative to and beneath the display. A window is provided in the chart or along an edge thereof to enable a pointer on the slide to be visible through the useful range of movement of the slide. On the slide is provided at least one column of data, the individual lines of data being viewed sequentially through another window through the chart. Destination points are displayed on the navigational chart in their appropriate analog positions and connected by lines to the edge of the slot along which the pointer moves. The data is so coordinated with the pointer than when the point is opposite a line connected to a desired destination point, the proper data such as latitude and longitude and time delay codes for that destination point appear in the window as required in Loran and Global Position Satellite (GPS) systems.
