What time frame is considered ‘night’ flying?

The definition of 'night' flying is critical for pilots to understand, particularly for adhering to regulatory requirements and safe operation practices. The correct answer identifies the time frame as spanning from sunset to sunrise. This period is significant because it encompasses the times when visibility is typically at its lowest, and pilots must rely more heavily on their instruments and navigational skills.

Understanding this period is essential for pilots, especially when it comes to training and licensing regulations that govern night flying privileges. Different rules apply during night conditions, affecting minimum visibility requirements, aircraft lighting, and even how a pilot prepares for a flight.

Other options do not correctly define the night flying period. For instance, the period from dawn to dusk would refer to daytime flying, while twilight to midnight covers only part of the night period but does not include all hours of darkness. Furthermore, sunrise to noon clearly pertains to morning hours, which are well before the conditions that define night flying. Thus, the most accurate time frame for night flying is indeed from sunset to sunrise.
