The minimum recovery rest period must include how many nights?

• A. 1 night
• B. 2 nights
• C. 3 nights
• D. 4 nights

Answer: (B)

Rest periods are designed to restore alertness and performance by giving the body time to recover after duty. Sleep during the night is the most restorative because it aligns with our natural circadian rhythm, making that sleep more effective. Because of this, the rule requires a recovery rest to cover more than one night, ensuring there are two nights of sleep opportunities within that break. This two-night window helps to reduce accumulated fatigue and keeps you sharper for the next duty period. If the rest included only a single night, some fatigue would likely remain, increasing the risk of fatigue-related errors.
