If recency of experience requirements for night flight are not met and official sunset is at 1830, what is the latest time passengers may be carried?

The most appropriate time for carrying passengers if the recency of experience requirements for night flight are not met is 1929.

In aviation, the definition of night flight is established based on the official sunset time. Night begins at sunset and extends until sunrise the following day. When it comes to carrying passengers, regulations stipulate that a pilot must not carry passengers during nighttime unless they have met specific recency of experience requirements.

Since official sunset is at 1830, nighttime starts immediately after this time. Therefore, the latest time passengers may be carried is just before the commencement of official night operations. In this case, that would be one minute before the official start of night flight, which is at 1830. However, regulations generally allow for operations to continue until the hour before night. Hence, if the aircraft is in operation under the day rules until 1929, it can still be within the limits for carrying passengers because those regulations typically permit operations until one minute before the official night period.

This concept helps to ensure that pilots adhere to safety protocols and operational limits, allowing for safe flight operations.
