What constitutes "night" flying according to FAA regulations?

The definition of "night" flying according to FAA regulations is the period from sunset to sunrise. This classification is crucial because it determines when certain flight rules and regulations apply, particularly regarding visibility, aircraft lighting requirements, and logbook endorsements for night flying.

During this specific time frame, pilots must adhere to various regulations that ensure safety and compliance with visual flight rules (VFR) and instrument flight rules (IFR). This includes the use of appropriate navigational and anti-collision lights, as well as the requirement for pilots to have logged specific night flying experience to carry passengers at night.

The other potential definitions provided in the answer choices do not align with FAA regulation definitions. Defining "night" as the period from midnight to noon, dusk to dawn, or sunset to nightfall fails to account for the distinct safety measures and regulations that are applicable only during the sunset to sunrise period, thereby highlighting the importance of accurately understanding the regulated definition for flight operations.
