What does fitness for duty mean?

• A. The pilot must be physically and mentally ready to safely operate.
• B. The flight plan is approved.
• C. The aircraft has passed maintenance checks.
• D. The crew has completed training.

Answer: (A)

Fitness for duty means a pilot is physically and mentally prepared to operate safely. This includes being free from illness or fatigue, not under the influence of substances, and within the allowed rest and medication guidelines so that judgment, perception, and reaction time are not compromised. It’s about the person’s current ability to perform all flight duties and to respond to emergencies, not just general procedures. The other options describe processes that support flight operations (flight plan approval, aircraft maintenance, and completing training) but they do not determine whether the individual is actually ready to fly at that moment.
