The fplan application is designed to assist general aviation pilots in creating flight plans for cross country flights in powered aircraft. It reads a planfile containing a description of the flight; departure and destination airports, navigation aids, intermediate waypoints, winds aloft, fuel consumption rates, and produces a flight plan including; wind corrected magnetic headings, distance, estimated time and fuel consumption for each leg, latitude, longitude and VOR fixes for each checkpoint, etc. A graphical preview of the flight is available on systems with X11 Windows and the XView Toolkit.
