Fatigue-related errors include which items?

• A. Procedural errors, unstable approaches, wrong runway, poor decision-making
• B. Navigation errors and weather misjudgments
• C. Cabin service delays
• D. Inaccurate fuel calculations

Answer: (A)

Fatigue reduces alertness, attention, memory, and judgment, so errors during flight often show up as failures to follow procedures, reduced monitoring that leads to an unstable approach, misperception or misreading cues that result in selecting the wrong runway, and poorer decision-making under pressure. These are classic ways fatigue impacts performance, making the listed combination—procedural errors, unstable approaches, wrong runway, and poor decision-making—the best reflection of fatigue-related errors. The other items describe issues that can occur for reasons other than fatigue (such as navigation or weather interpretation being influenced by factors beyond fatigue, or tasks like cabin service delays or fuel calculations being affected by workload or process inefficiencies rather than fatigue alone).
