Background:

Most task performance and neural activity research occurs in labs, limiting real-world applicability.
Field studies, especially in extreme environments like active flights, are rare.
Understanding cognitive load in operational settings is crucial for safety.

Purpose of the Study:

To investigate the impact of varying flight procedural complexity on electroencephalography (EEG) activity in military helicopter pilots during actual flight.
To establish a link between cognitive workload and neural signatures in a high-stakes operational environment.

Main Methods:

In-flight electroencephalography (EEG) recordings were obtained from military helicopter pilots.
EEG data was analyzed across flight procedures of differing complexity levels (e.g., takeoff, landing, flight exercises).
EEG power spectrum analysis was used to quantify neural activity changes.

Main Results:

Flight procedural complexity significantly modulated the EEG power spectrum.
Highly demanding procedures (takeoff, landing) correlated with increased EEG power in higher frequency bands.
Less demanding procedures (flight exercises) showed lower EEG power in the same frequency bands.

Conclusions:

In-flight EEG can effectively reflect cognitive performance variations related to task complexity in pilots.
EEG monitoring shows potential for evaluating operator cognitive states in challenging, real-life scenarios.
This research could contribute to preventing aviation accidents by monitoring pilot cognitive load.
