How many pilots may rest at a time during controlled rest?

• A. Two
• B. Three
• C. One
• D. Four

Answer: (C)

Controlled rest is a fatigue-management practice in a two-crew cockpit where the aircraft must always have a pilot actively monitoring and ready to take control. Only one pilot may rest at a time because maintaining continuous cockpit oversight and the ability to respond immediately is essential for safe flight. The other pilot stays at the controls, monitoring flight path, automation, and all critical parameters, so the airplane remains under active supervision. The resting pilot remains secured with a seat belt and is prepared to awaken and resume control as needed, often with automation helping reduce workload while the other pilot maintains vigilance. Having more than one crew member resting concurrently would leave the flight deck without active control, which is not permitted.
