Glass cockpits promote the development of some incorrect gaze habits, e.g. to spend too much time looking at in-board instruments [17]. This wrong behavior affects the flight safety in visual flight rule (VFR) because it reduces the time spent scanning the outside world. To prevent this incorrect habit as earlier as possible, we have developed a new visual strategies training system, PilotGazeTrainer (PiGaT). This system is based on the use of an eye-tracker and on two main principles: (i) real-time analysis of gaze behavior and (ii) the automatic trigger of notifications (visual or audio). This article details the PiGaT system and an abstract task (Abstract Flying Task, AFT) which was used to realize an experimental validation. Results of this ad-hoc experimentation, with 81 students, show that the PiGaT system can permanently change eye behavior without degrading the performance of AFT. Finally, we discuss potential usages offered by the PiGaT.
