Fatigue in Aviation: A Silent Threat to Safety
An Invisible but Dangerous Risk When we think of threats to aviation safety, we often picture mechanical failures, harsh weather, or even cybersecurity breaches. Yet, one of the most persistent and underestimated risks isn’t a technical fault—it’s fatigue . Fatigue is not just feeling tired; it's a physiological state that dulls alertness, slows reaction times, and clouds judgment—an invisible threat with very real consequences. Understanding Fatigue in Aviation Fatigue is especially dangerous in aviation because it degrades both physical and cognitive performance. Whether it's a pilot on a long-haul flight, a maintenance crew working overnight, or an air traffic controller managing a congested airspace during a night shift, fatigue creeps in quietly, making errors more likely. According to Chen et al. (2019), fatigue is linked to reduced vigilance, decision-making errors, and a higher probability of procedural violations. This becomes particularly critical in time-sensitiv...
