Which term describes 'Adversely affects a pilot's mental and physical abilities'?

• A. Fatigue
• B. Stress
• C. Eating
• D. Perspective Illusion

Answer: (B)

Stress is the state that describes how emotional and psychological strain can degrade both thinking and physical performance. It can impair perception, memory, and decision-making, while also increasing muscle tension and physiological arousal, which slows reaction times and reduces fine motor control. In drone piloting, that combination means poorer situational awareness, slower and less accurate responses, and more errors under pressure. While fatigue also harms performance, it refers to tiredness from insufficient rest rather than the broader strain and pressure described by stress. Eating isn’t a term used to describe impairment, and perspective illusion isn’t a standard concept in this context.
