Pilot fatigue is mainly the result of insufficient rest and high operational demands, which reduce alertness and performance.
Key causes:
• Long duty hours
Extended flight and standby periods can exceed natural energy limits.
• Irregular schedules & time zone changes
Disrupt the body’s internal clock (Circadian Rhythm), especially during night operations or long-haul flights.
• Lack of quality sleep
Short or interrupted rest periods prevent proper recovery.
• High workload & stress
Demanding phases of flight, decision-making pressure, and operational stress increase mental fatigue.
Why it matters:
Fatigue can lead to:
• Reduced situational awareness
• Slower reaction times
• Poor decision-making
In aviation safety, managing fatigue is critical and is formally addressed through systems like Fatigue Risk Management System (FRMS).
It’s important that safety department monitors fatigue by encouraging pilots to file ASR report.
Managing pilot fatigue is a core safety responsibility, and most operators address it through a structured, data-driven approach built around a Fatigue Risk Management System.
