If a pilot does not meet the recency of experience requirements for night flight and official sunset is 1900 CST, what is the latest time passengers should be carried?

The correct choice is based on understanding the regulations regarding carrying passengers during night flight when a pilot does not meet the necessary recency requirements.

For pilots who have not recently flown at night, the regulations stipulate that they should not carry passengers one hour after official sunset. Official sunset at 1900 CST means that pilots who do not meet recency requirements can fly during the day portion but must conclude passenger operations before night flight conditions begin, which is classified as one hour after sunset.

Therefore, at 1900 CST, the official sunset occurs, and the one-hour limit means that they cannot carry passengers after 1959 CST, which allows for the latest passenger carrying time just before night restrictions fully take effect.

This choice reflects adherence to safety regulations designed to ensure that pilots have the necessary experience and situational awareness before flying at night.
