Cognitive Workload and Psychophysiological Parameters During Multitask Activity in Helicopter Pilots.

Area of Science:

• Aviation Psychology
• Human Factors Engineering
• Cognitive Neuroscience

Background:

• Helicopter pilots face complex tasks demanding significant cognitive resources, potentially impairing performance.
• Existing research often uses artificial settings, limiting ecological validity.
• This study investigates workload, emotional state, and physiological markers in a realistic helicopter simulation.

Purpose of the Study:

• To jointly explore cognitive workload, emotional state, and physiological responses in helicopter pilots during a simulated mission.
• To identify distinct profiles of pilot response to varying workload levels.
• To understand the interindividual variability in these responses.

Main Methods:

• Utilized a helicopter full flight dynamic simulator for a realistic flight mission.
• Assessed workload level, skin conductance, RMS-EMG (root mean square of electromyography), and emotional state.
• Analyzed data from six participating pilots across two missions.

Main Results:

• Expert pilots exhibited minimal physiological changes and positive emotions, even with increased difficulty.
• Non-expert pilots showed escalating physiological values and a wider range of emotional states (positive/negative).
• Intermediate pilots displayed expert-like emotional states but non-expert physiological patterns.

Conclusions:

• High interindividual variability exists in the relationship between physiological and psychological parameters and workload.
• Physiological markers alone may not reliably predict a pilot's decision-making capacity under stress.
• Understanding these complex interactions is crucial for aviation safety and training.
