A couple of weeks ago, one of the fellows (yes, you, MSmith) from the Island Virtual Airways, the virtual airline based on FlightGear, poked me and was asking me if there is a way to show only their airline pilots on FGMap. After spending a few coding train trips, I’ve added a very simple pilot filtering feature. Currently you can filter by the callsign and the aircraft. It also has query string support, so you can do things like http://mpmap02.flightgear.org/?pilots_filter_callsign=blah
Check it out at http://mpmap02.flightgear.org/. Code is in my usual git repo.
