Real name: James Turner, 'james' on FlightGear IRC. Best to get in touch via email (or the developer mailing list).
Working on various areas, most especially GPS/FMS support in the code code, and support for digital/glass cockpit displays in the near future. I've also worked on the navradio code, overhauling some of the core data models (especially relating to spatial indexing and searches), and many general code cleanups.
