Mermoz is an application for helping private pilots to do their flight planning. It is designed to work with the French and Swiss ICAO VFR maps.
However I did an English translation. So you may give it a try even if you don't speak French. And if someday you come to fly in France or Switzerland, then it might help you.
Last (but not least), Mermoz is the name of a famous French aviator who flew from 1920 to 1936 between France and South America.
Nice reviewing job.Note that you can create routes in more than one mapped region: use the menu command Route > New and select departure and destination airports.Eric Le Ponner - Author of Mermoz
