What is the main purpose of a flight log in UAS operations?

The main purpose of a flight log in UAS operations is to record flight details for compliance and maintenance. Keeping an accurate and detailed flight log helps operators document essential information such as flight duration, operating conditions, maintenance performed, and any anomalies observed during the flight. This information is crucial for regulatory compliance, as many aviation authorities require operators to maintain records of their operations for safety, accountability, and legal purposes. Furthermore, maintaining a comprehensive flight log aids in the regular maintenance and inspection of the UAS, ensuring it functions safely and efficiently over time.

While visual line of sight, calibration before takeoff, and tracking weather conditions are all important components of UAS operations, they do not encompass the primary function of presenting a detailed record of flights like a flight log does. The flight log centers on compliance and maintenance, which is integral to safe and lawful UAS operation.
