Which record should a RPAS owner maintain according to regulations?

A RPAS (Remotely Piloted Aircraft Systems) owner is required to maintain records that support operational safety and accountability. Among the choices given, keeping a record of the names of pilots and crew members is crucial for regulatory compliance. This record ensures that all individuals operating the RPAS are properly licensed and qualified to do so, which is essential for safety management and accountability in aviation operations.

Maintaining such records also facilitates the verification of pilot credentials during audits or inspections, thereby ensuring that the RPAS operates within the legal framework and adheres to the required standards set by aviation authorities. It helps track which pilots are flying in which conditions, supporting operational continuity and safety compliance.

In contrast, while flight times and locations, weather conditions, and personal observations are also important for operational insights and safety analysis, they do not hold the same regulatory requirement for documentation as the names of pilots and crew members. These other aspects can enhance safety and operational awareness, but the primary regulatory focus is on ensuring that qualified individuals operate the RPAS.
