Which errors are linked to fatigue?

• A. Procedural errors, unstable approaches, wrong runway, poor decision-making
• B. Navigation errors only
• C. Weather-related errors
• D. Communication errors are the sole fatigue-related issue

Answer: (A)

Fatigue dulls alertness, slows information processing, and weakens memory and judgment, so errors tend to appear across complex tasks that require constant attention and decision making. In flight, this shows up as procedural errors (n missing steps or skipping checks because recall or attention is impaired), unstable approaches (less consistent control and delayed corrective actions as monitoring lapses), wrong runway (misperception or lapse in situational awareness leading to an unsafe choice), and poor decision-making (weighing risks and options becomes slower and less reliable). Together, these reflect how fatigue can undermine both the execution of standard procedures and the quality of on-the-spot judgments. Navigation errors alone don’t capture the broader spectrum of fatigue-affected performance, and weather-related errors, while potentially influenced by fatigue, aren’t inherently fatigue-specific. Communication errors can be influenced by fatigue but aren’t the only fatigue-related issue, and fatigue affects many other cognitive and procedural aspects beyond communication.
