Royal Netherlands Air Force Trials AI to Monitor Fighter Pilots’ Brain Activity

Innovative Approach to Pilot Training

The Royal Netherlands Air Force is pioneering a novel training system that employs artificial intelligence to monitor the brain activity of trainee fighter pilots, adjusting virtual missions in real time based on cognitive workload. This initiative represents a significant shift from traditional military flight training, which typically follows fixed lesson plans and predetermined difficulty levels. Instead, the Dutch system offers a personalized training experience that dynamically responds to the pilot’s mental state, aiming to optimize learning by maintaining an ideal level of challenge.

Led by Dr. Evy van Weelden at the Royal Netherlands Aerospace Centre in Amsterdam, the project utilizes a brain–computer interface (BCI) to capture electrical signals from electrodes placed on the scalp. As pilots engage in virtual reality (VR) missions, an AI model analyzes these signals to estimate cognitive workload, identifying patterns associated with mental strain or ease rather than interpreting specific thoughts. When the AI detects cognitive overload, it reduces the difficulty of subsequent missions; conversely, if the workload is low, it increases the challenge to maintain engagement.

Trial Results and Challenges

Fifteen trainee pilots participated in the study, each completing multiple VR missions under two conditions: a conventional, pre-programmed progression and an AI-driven adaptive system that adjusted difficulty across five levels based on real-time brain data. Initial feedback indicates a preference among pilots for the adaptive training style. However, the research also uncovered a notable limitation: despite the positive reception, the adaptive system did not yet lead to measurable improvements in flying performance.

The trials further revealed challenges in interpreting brain data accurately. For example, six pilots exhibited minimal variation in difficulty level adjustments, raising concerns about the system’s sensitivity and reliability. These findings reflect broader skepticism within the industry regarding the dependability of AI-driven solutions. Experts emphasize the need for robust, coherent AI applications rather than experimental demonstrations that may lack practical efficacy.

Broader Context and Future Implications

The demand for adaptive simulators is intensifying as pilot training remains costly and resource-intensive, with every hour of flight consuming valuable fuel, airframe life, and maintenance resources. Simulators and VR environments have become central to training, covering everything from basic handling to complex combat scenarios. Yet, maintaining trainees within an optimal mental “sweet spot” remains a persistent challenge. Tasks that are too simple risk complacency, while overly difficult exercises can overwhelm and impede learning.

Traditionally, instructors have managed this balance through fixed-stage scenario designs, irrespective of individual progress. The Dutch initiative seeks to automate this process by leveraging real-time brain data to tailor training to each pilot’s cognitive state. Meanwhile, other air forces, including the United States, are also investing in AI technologies to reduce pilot workload, reflecting a broader trend toward integrating AI in aviation training and operations.

This movement is part of a wider AI arms race, with technology firms such as Anthropic and xAI competing for leadership in the field. The outcomes of the Royal Netherlands Air Force’s trials may influence not only the future of pilot training but also the broader adoption of AI in high-stakes environments. The central challenge remains ensuring that adaptive AI systems are both innovative and reliable, delivering tangible improvements in operational effectiveness.
