'''ATC-pie''' is an [[air traffic control]] simulation program allowing to play solo games, connect to [[FlightGear]] multi-player networks and set up tutorial sessions for teacher supervision of an ATC student. It features en-route centre control (CTR) as well as airport-based service (TWR, APP, GND...)
where 3d tower viewing is possible. It is essentially designed for realism and simulates many tasks and situations of real-life ATC such as:
* strip rack and sequence management;
* transponder identification;
* routing and conflict anticipation.
The program is free and open source, and programmed in Python3 for Qt5 hence system-independant. Only Python3 and its Qt5 bindings must be installed. That done, it is meant to work straight away, with no make/compile command to run or external resource to install. The whole world is immediately available on radar. Tower viewing requires
a running FlightGear installation and the appropriate aircraft and scenery.
