If recent experience requirements for night flight are not met, when is the latest time passengers may be carried if official sunset is at 1830?

When considering the regulations surrounding night flight, it is essential to understand how the timeframes are calculated based on sunset. If the recent experience requirements for night operation are not met, the latest time that passengers may be carried is determined by a buffer period after sunset to allow for a transition into night flying requirements.

In this scenario, with official sunset at 1830, the calculations stipulate that a pilot can carry passengers until a set time after sunset. The specific regulation indicates that this time is typically 1 hour after official sunset. Thus, adding 1 hour to 1830 results in a cutoff of 1930. However, because of additional considerations, the time can be extended to 1929, which is one minute before 1930.

This is why the correct answer is 1929; it accounts for the official end of civil twilight, where night flying regulations come into effect. After this time, without proper recent experience, it is not permissible to carry passengers, highlighting the importance of thorough understanding and adherence to night flight regulations by pilots.
