How is night defined for the purposes of flying?

Night, for the purposes of flying, is defined as the period beginning one hour after sunset and ending one hour before sunrise. This definition is significant because it establishes the time frame during which additional regulations and requirements apply to flying, such as the need for special lighting and increased visibility considerations. Understanding this timeframe is vital for pilots, as it informs them of the limits and responsibilities they face when flying in low-light conditions.

The choice of one hour after sunset and one hour before sunrise is particularly important because it allows for twilight conditions, which can still present challenges in visibility and flying safety. This definition ensures that pilots are operating under conditions that may require heightened awareness and adherence to specific regulations concerning night flying.

Understanding this definition helps pilots prepare adequately for flights that may extend into night conditions, emphasizing the importance of compliance with all relevant regulations to ensure safety.
