The European Cockpit Association (ECA) has published survey results showing that tiredness is a persistent and frequently hidden problem in aviation. Among the 7,200 pilots from 32 countries who participated, more than half reported that at least once in the previous three months they had operated a flight before realising in hindsight that they should have declared themselves unfit to fly due to fatigue. Common signs of fatigue included unintentional head drops, struggling to keep their eyes open, and microsleeps, brief, uncontrollable attention lapses, with over 76% experiencing at least one such moment in the previous four weeks.
Barriers to reporting fatigue are significant. Nearly half of pilots (47%) feared backlash from management, while 44% avoided drawing attention to themselves, and 35% hesitated to inconvenience their employer. Although 82% knew how to file fatigue reports, only 12% trusted the process, and just 11% said their reports had actually led to safety improvements. Half of those surveyed rated their airline’s fatigue management as ineffective or nonexistent.

Fatigue in aviation arises from sleep deprivation, prolonged work shifts, or insufficient rest. The ECA highlights that chronic fatigue, accumulated over time, is often harder to recognize than sudden sleep loss. While fatigue has long been acknowledged as a safety threat, the industry continues to face challenges with underreporting. A 2026 European Union Aviation Safety Agency (EASA) study connected fatigue to scheduling demands, roster adjustments, and extended voluntary work hours.
Pilots may avoid reporting due to professional risks, yet unaddressed fatigue directly threatens safety. The ECA’s findings indicate that confidence in reporting systems, and the readiness to use them, must strengthen to lower dangers. EASA’s 2026 report emphasized the need for targeted safety initiatives to improve reporting quality, awareness, and support a workplace culture where personnel can declare themselves tired without fear of reprimand.
