What is the maximum time a pilot can fly with passengers without meeting night flight experience requirements if sunset is at 1830?

The maximum time a pilot can fly with passengers without meeting night flight experience requirements is determined by the sunset time and the definition of night flight for the purposes of pilot qualifications. In this scenario, sunset is at 1830.

According to FAA regulations, night flight is defined as the time from one hour after sunset to one hour before sunrise. Hence, if sunset is at 1830, night officially begins at 1930. Therefore, a pilot can fly with passengers until 1930 without needing to meet additional night flight experience requirements.

Given the context, the correct answer indicates that the latest time a pilot can operate passengers without meeting these requirements is 1929, which occurs just before night time begins at 1930. This ensures that the pilot is still operating within the allowable time window before the legal definition of night flight takes effect.

The other times listed in the options either extend beyond this limit or are not relevant to the regulations that define the boundaries for flying with passengers at night.
