Can GPSNavX calculate and display the closest point of approach (CPA) for a particular AIS or radar target?

This is particularly useful if you're sailing through shipping lanes, such as the mid-English channel traffic separation scheme.

The next release of MacENC and GPSNavX will compute and display Closest Point of Approach for the selected target in the "More Info..." sheet.
