Hello everyone,
I am pleased to announce rfgfs, a package for R that allows planning a flight between two airports, using the airport, airway, navaid and navfix data that ship with FlightGear. It also calculates magnetic declination using the same formula that FlightGear uses, and can plot the created flight plan in a kml file for viewing with Google Earth.
Creating this as an R package will raise a few eyebrows, I guess, but R is what I I am most familiar and spend most of my time with (I'm an epidemiologist). I wanted an easy solution to fly around in my Tu-154B, so R was the natural choice for me. Hopefully it can be useful to other people as well -not just the statisticians among us- since there are few flight planning solutions for FlightGear.
Please find it at GitHub: https://github.com/thlytras/rfgfs. Testing and feedback is very, very welcome, as are suggestions for new features to be included. Please create an issue at the GitHub repo, or post a forum message in this thread. Happy flight planning!
