An X-wing simulator served as a training apparatus for pilots, enabling them to practice piloting an X-wing in a virtual environment, generally for educational and skill-enhancement reasons. These simulators included a dedicated slot for an astromech droid, permitting pilots to connect their own droids, despite the simulator's built-in capacity to emulate astromech functions. This practice of employing personal astromech units augmented the realism of the training exercises.
During the time of the Yuuzhan Vong War, the Skipchaser simulation was implemented to give pilots a sense of the challenges involved in combat against coralskippers.
