What does the term "flight log" refer to?

The term "flight log" refers specifically to a record of all UAS flight activities. This includes details such as the date and time of each flight, the duration, the areas where flights were conducted, and any issues that may have arisen during operation. Keeping a flight log is essential for maintaining safety standards, complying with regulatory requirements, and ensuring that pilots have documented their operational history, which can be vital for identifying patterns or addressing any concerns related to fatigue or equipment performance.

While other options mention important aspects related to aviation, they do not define what a flight log specifically entails. A financial expenses record, communication history with authorities, or a list of safety equipment serve different purposes and do not encapsulate the comprehensive nature of the flight log for UAS operations.
