This study delves into the cognitive and ergonomic aspects of military UAV operations, focusing on pilots' mental workload and interface usability through advanced eye-tracking technology. The research encompasses a group of 24 military pilots participating in 30-minute flight simulations, with their eye movements meticulously recorded by Tobii Pro Glasses 2 and analyzed using Tobii Pro Lab software. Alongside this objective data, pilots' subjective perceptions of workload and interface usability are gauged through NASA-TLX and SUS questionnaires. The objective is to establish a correlation between eye-tracking data and pilots' subjective assessments, thereby providing a comprehensive view of the cognitive processes and ergonomic challenges faced in military UAV operations. This study is poised to offer significant contributions to the fields of military aviation training and interface design, underscoring the necessity of integrating technological advancements with human factors to enhance operational safety and efficiency.
