What flight documentation is mandatory for commercial operations?

For commercial drone operations, having evidence of a Permission for Commercial Operations (PfCO) is essential as it demonstrates that the operator has met the necessary training and safety requirements set by the regulatory authority. This permission is a key component of legal operations in commercial airspace, ensuring that the operator understands risk management and operational limits. Additionally, maintaining flight logs is crucial as it provides a record of flying activities, which is important for accountability, compliance, and safety assessment. Logs can help track the maintenance and performance of the drone, ensuring safe operations.

The other options, while they may contain important aspects of drone operations, do not encompass the necessary legal requirements specifically linked to the authorization to operate commercially. For instance, proof of registration and insurance documents may be part of overall compliance but are not as directly tied to the permission needed to carry out commercial flights as the PfCO. Individual flight plans can vary depending on specific missions but are not universally required for all commercial operations, making them less critical than the documented evidence of proper permissions and logging of flight activities.
