The Kelpie Flight Planner for Flightgear. 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.
