Outline
In order to enhance the proficiency of general aviation pilots in walk-around inspections and ensure aviation safety, eye-tracking technology was employed to measure and analyze the completion rates and fixation behavior characteristics of pilots categorized by experience level. Based on the walk-around checklists and inspection procedures, Diamond DA-40D aircraft was divided into six Areas of Interest (AOI), including the engine, wings, fuselage, landing gear, and empennage. During the participants' walk-around inspections, the completion rates of the walk-around checks and the characteristics of fixation behavior for these six AOI were recorded by means of an eye tracker. The results show that the completion rates of inspections in five AOI, including the empennage, engine, right wing, left wing, and left landing gear, were significantly higher in the veteran group than in the novice group. With the increase in flight experience, the completion rates of general aviation pilots' walk-around inspections gradually improve. Significantly higher total fixation durations and total fixation counts were observed in the experienced group compared to the novice group across five AOI: the engine, right landing gear, right wing, left wing, and left landing gear. A significantly longer average fixation duration on the engine AOI was demonstrated by the novice group relative to the experienced group. Recommendations are provided for training to place greater emphasis on the empennage section, right wing, left wing, and left landing gear areas. Additionally, enhancement of novices' inspection capabilities regarding the engine and left landing gear areas is suggested.
