Key result

An integrated multi-measure approach using EEG, heart rate variability, and subjective ratings demonstrated reliable within-subject consistency (mean ICC 0.59-0.85) for monitoring pilot workload.

Why the study?

Managing cognitive demand is critical for aviation safety, but accurately assessing pilot workload during complex flight maneuvers remains challenging.

Population

Main Result

Effect estimate: mean ICC 0.59-0.69

An integrated multi-measure approach using EEG, heart rate variability, and subjective ratings is feasible and reliable for continuously monitoring real-time cognitive workload in pilots.

Limitations

  • Substantial between-subject variability highlights the importance of individualized neurocognitive profiling
  • Challenges posed by individual differences
  • Substantial between-subject variability

D’Alessandro et al. (2024) conducted an observational in Cognitive workload (n=6). High-workload flight scenarios vs. Lower demand periods was evaluated on Within-subject consistency of EEG engagement indices and heart rate variability metrics (mean ICC 0.59-0.69). An integrated multi-measure approach using EEG, heart rate variability, and subjective ratings demonstrated reliable within-subject consistency (mean ICC 0.59-0.85) for monitoring pilot workload.
