  Fatigue Fatigue is one of the most treacherous hazards to flight safety as it may not be apparent to a pilot until serious errors are made. Fatigue can be either acute (short-term) or chronic (long-term). Acute fatigue ... mental strain, including strenuous muscular effort, immobility, heavy mental workload, strong emotional pressure, monotony, or lack of sleep. Acute fatigue caused by training operations may be physical or mental, or both. It is not necessarily a function of physical strength…

  Fatigue Fatigue is frequently associated with pilot error. Some of the effects of fatigue include degradation of attention and concentration, impaired coordination, and decreased ability to communicate. These factors seriously influence the ability to make effective decisions. Physical fatigue results ... sleep loss, exercise, or physical work. Factors such as stress and prolonged performance of cognitive work result in mental fatigue. Like stress, fatigue falls into two broad categories: acute and chronic. Acute fatigue is short term and is a normal…

  consumption (dehydration, hangover, and headaches, etc.) may trigger a “P” hazard for longer than eight hours after consumption. 11827 • Fatigue–How alert is the pilot? Fatigue may result from insufficient sleep. However, sufficient sleep only corrects acute fatigue. Chronic fatigue ... involve multiple factors and requires additional analysis and remedy. Fatigue can be intensified by hypoxia as well as emotional state. While fatigued pilots have fallen asleep while flying, the effects of fatigue may be subtle. For example, fatigue may degrade…

  Fatigue continues to be one of the most treacherous hazards to flight safety, as it may not be apparent to a pilot until serious errors are made. Fatigue is best described as either acute (short-term) or chronic (long-term ... normal occurrence of everyday living, acute fatigue is the tiredness felt after long periods of physical and mental strain, including strenuous muscular effort, immobility, heavy mental workload, strong emotional pressure, monotony, and lack of sleep. Consequently, coordination and alertness…

  used to describe a range of experiences from sleepy, or tired, to exhausted. Two major physiological phenomena create fatigue: sleep loss and circadian rhythm disruption. Figure 1-6. Fatigue is a threat to aviation safety because it impairs alertness ... performance. Fatigue is a normal response to many conditions common to flight operations because characteristics of the flight deck environment, such as low barometric pressure, humidity, noise, and vibration, make pilots susceptible to fatigue. The only effective treatment for fatigue…

  Fatigue Fatigue is a major human factor that has contributed to many maintenance errors resulting in accidents. [Figure 14-23] Fatigue can be mental or physical in nature. Emotional fatigue also exists and affects mental and physical performance. A person ... said to be fatigued when a reduction or impairment in any of the following occurs: cognitive ability, decision-making, reaction time, coordination, speed, strength, or balance. Fatigue reduces alertness and often reduces a person’s ability to focus…
