Fatigue-related errors include which of the following?

Fatigue-related errors include which of the following?

• A. Procedural errors, unstable approaches, wrong runway, poor decision-making
• B. Delays in fuel calculations only
• C. Seat belt misuse
• D. Weather briefing delays

Answer: (A)

Fatigue reduces attention, memory, judgment, and situational awareness, making it more likely for a crew to slip into errors that affect how they execute procedures, monitor flight path, identify surroundings, and make decisions. The best choice reflects the range of mistakes fatigue can cause: not following procedures, producing an unstable approach, selecting the wrong runway, and making poor decisions. These are all classic ways fatigue disrupts performance because they stem from worn-down cognitive resources and impaired risk assessment. The other options describe issues that can occur in aviation but aren’t typical fatigue-related error patterns—delays in fuel calculations alone ignore the broader impact of fatigue on planning and monitoring, seat belt misuse is more about rule compliance, and weather briefing delays can arise from many non-fatigue factors.
