Which document must drone pilots carry at all times while flying?

Drone pilots are required to carry their Remote Pilot Certificate at all times while flying. This document serves as proof that the pilot has undergone the necessary training and has been granted authorization to operate the drone legally. The Remote Pilot Certificate is issued by the Federal Aviation Administration (FAA) after passing the appropriate knowledge test, demonstrating that the pilot understands the regulatory requirements, airspace classification, weather, and safe operational practices.

While a flight log can be useful for tracking flight hours and experiences, and maintaining the drone's maintenance manual is important for ensuring the drone's functionality and safety, these documents are not mandated to be carried by the pilot during flights. Similarly, insurance documentation, while advisable, is not a requirement set forth by the FAA for pilot operation. Thus, it is crucial for drone pilots to always have their Remote Pilot Certificate on hand to validate their authority to fly under FAA regulations.
