Objective: This study was to compare and quantify the level of situation awareness (SA) between expert and novice pilots using eye tracking features. Background: Successful and safe landing requires a high SA of pilots. However, existing studies have examined simple SA status, which was lack of comprehensively understanding by linking SA model and quantitative features. Method: The experiments were conducted by five repeated landing for four expert and four novice pilots using flight simulator and eye tracking equipment. Three eye tracking features (visit frequency, dwell time ratio, scan path entropy) were calculated for reflecting three level of SA model (perception, comprehension, projection). The classification of SA status was performed by applying significant eye tracking features, developing binary logistic regression model, testing 5-fold cross validation. Results: Visit frequency of expert pilots was 138%, 47%, 85%, 67%, 117%, and 91% higher than novice pilots in RPM, VVI, altimeter, heading, airspeed, and attitude areas of interest (AOIs) respectively; while 50% and 33% lower in runway and outside AOIs respectively. Dwell time ratio of expert pilots was 38% and 42% higher than novice pilots in runway and outside AOIs respectively; while 62%, 62%, and 65% lower in altimeter, airspeed, and attitude AOIs respectively. Scan path entropy of expert pilots was 33% higher than novice pilots in outside AOI; while 29% lower in attitude AOI. Sensitivity of the classification model for SA high and low status was 73.7%.Conclusion: This study showed that the difference between SA level of expert and novice pilots could be identified by using novel eye tracking features and applied to develop classification model for SA high and low status. Application: The results of this study can be used as objective data of strategy establishment or training feedback for novice pilots.
