This simple plan allows crews to use cardinal heading after departure and ranging to get to and from operating areas. You can cut segments that are over densely populated areas

This system workes best with GPS equipped aircraft for range data off an airport waypoint. Pilots can display the center airport waypoint using "bearing pointer" display on the GPS, thus having true radial (RMI) type feedback to maintain SA. Excellent system for areas with poor natural features to determine area borders.

Deconflict entering and exiting aircraft using entry and exit waypoints near the inner circle.
