FAA 107 Commercial Drone Pilot Test 2025 – 400 Free Practice Questions to Pass the Exam

The FAA defines "night" for UAS operations as the period between the end of civil twilight and the beginning of morning civil twilight. This definition is significant because it aligns with the operational guidelines for drone pilots who may need to follow specific regulations concerning lighting and visibility when conducting flights during these times. Civil twilight refers to the time when the sun is just below the horizon, allowing for sufficient natural light. By defining night in this manner, the FAA provides a clear framework for safe flight operations in reduced visibility conditions, ensuring that drone pilots can assess the risks associated with flying during periods when light is limited.

Understanding the nuances of this definition helps ensure safe UAS operations and compliance with FAA regulations while promoting situational awareness regarding environmental conditions.
