...This Java based Gui flight planner uses the airport and navaid databases of the Flightgear, allowing the user to search for airports and navigation aids and plan flights between them. [Note: Requires Java 1.10 or above]
This program is no longer being actively developed or supported.
All future work is being undertaken on a port to Rust/Gtk at https://github.com/shartrec/kelpie-flight-planner. But is still in the very early stages.
