From the developer:
For helping private pilots to do their flight planning. You draw your route and mark your waypoints like on a paper map. Mermoz fills the navigation log with headings, distances and times. Then you print the log and go to flight! Mermoz is currently designed to work with the french, swiss and U.S. VFR maps. Have a good flight!
