INTRODUCTION: Pilots often experience acute stress during flights, potentially affecting flight safety. The effect of acute stress on instrument-based tasks remains unclear. This study aimed to investigate the influence of acute stress on subjects' performance in two crucial tasks: the attitude recovery task and the landing judgment task. METHODS: A total of 91 student pilots were divided into a control group and a stress group. Both groups completed a square task, with the stress group exposed to high-intensity noise to induce acute stress. Subsequently, 42 subjects performed an attitude recovery task using two formats of the attitude indicator: moving horizon and moving aircraft. The remaining 49 subjects performed a landing judgment task with three complexity levels using a landing instrument. Heart rates, trait-state anxiety scores, response times, and accuracy of the tasks were analyzed. RESULTS: Heart rates and state anxiety scores increased following stress induction. In the attitude task, the stress group responded faster than the control group in the moving-horizon format (467.55 ms vs. 491.45 ms) but had lower accuracy (98.65% vs. 99.73%). In the moving-aircraft format, response times (stress: 454.15 ms, control: 474.73 ms) and accuracy (stress: 98.55%, control: 99.38%) showed no significant differences between the two groups. In the low-complexity landing task, the stress group (1015.79 ms) responded faster than the control group (1168.17 ms). DISCUSSION: The impac...
