Which term below best matches the description 'Adversely affects a pilot's mental and physical abilities'?

• A. Fatigue
• B. Stress
• C. Eating
• D. Spatial Disorientation

Answer: (B)

Stress is the body’s response to demands, and in flight those demands can come from workload, time pressure, emergencies, weather, or equipment issues. That response can impair cognitive functions like memory, attention, and decision-making, and it can also affect physical performance such as reaction time and coordination. Because the description points to a general adverse impact on both mental and physical abilities, stress is the best fit. Fatigue describes tiredness from lack of rest and can also degrade performance, but the term here refers more broadly to the stress response that encompasses both mental and physical impairment. Spatial disorientation is a specific perceptual error, and eating isn’t related to the impairment described.
