The analysis of eye movements is a popular tool in traffic safety research. Among different motions of eye movements, gaze is a major parameter of eye tracking process. Besides fixation duration time and fixation duration percentage, transition matrix from one gaze state to the other can catch the dynamics of gaze patterns and capture the important features of eye movements. In this study, an inexpensive experiment system is designed to create a simulation environment where the participants can performance flight tasks. This system combines up-to-date eye tracker (FaceLAB 4.0), flight simulation (Microsoft Flight Simulator X and Logitech G940), and data management tools. Experiments are designed to test critical flight phases under different meteorological conditions. During the experiments, gaze views are divided into three zones: cabin instrument panel, outside and others. Markov Chain models are applied to analyze the data collected from the experiment system. State transition probability matrix and stationary distribution vector are computed. The result shows that there are no significant differences among gaze state transition matrices, for all the scenarios. In addition, the total flight time and gaze ratio on zones are unstable.
