ATC-pie is an air traffic control simulation program featuring solo sessions, multi-player connections (through FGMS) and tutorial sessions for teacher supervision of an ATC student. It simulates en-route centre control (CTR) as well as airport-based services (TWR, APP, GND...), and allows 3D tower viewing through FlightGear. It is essentially designed for realism, not as a game.
