Why the study?

It was investigated whether high cognitive task load for aircraft pilots could be identified by analysing heart-rate variability during simulated flight missions.

Does a heart-rate variability index identify high cognitive task load in cadet pilots during simulated flight?

Population

Cadet pilots (n = 68 in research phase, n = 139 in validation group)

Comparison

High vs low cognitive task load conditions

Design

Development and validation study

Overview

May support HRV monitoring for pilot cognitive load; leaves open operational validation before any practice change.

Structured PICO

Does a heart-rate variability index identify high cognitive task load in cadet pilots during simulated flight?

P
Population
207 cadet pilots (n=68 in research phase, n=139 in validation phase) performing simulated flight missions including plane tracking, anti-gravity pedalling, and reaction tasks.
I
Intervention
Heart-rate variability index (HRVI) derived from principal component analysis of electrocardiogram data.
C
Comparator
Low cognitive task load conditions.
O
Outcome
Identification of high cognitive task load (CTL).surrogate

A composite index based on heart rate variability can objectively identify high cognitive task load in pilots during simulated flight, potentially improving training and safety.
