helicopter-fatigue-analysis

This repository contains the analysis code and dataset for a study examining helicopter pilot fatigue across different flight types.

The analysis investigates:

• Changes in fatigue levels before and after flight,
• Differences between instructional and operational missions,
• Relationships between objective (PVT) and subjective (KSS, SP) fatigue measures,
• The effect of instructional workload on fatigue.

Dataset

24 flight records from 12 helicopter pilots

Fatigue measured via:

• PVT (Psychomotor Vigilance Test),
• KSS (Karolinska Sleepiness Scale),
• SP (Samn–Perelli Fatigue Scale).
