What is one of the directly mentioned normal operating procedures a pilot must establish?

Establishing recovery procedures after landing is a critical aspect of a pilot's normal operating procedures. These procedures ensure that the pilot is prepared to handle the aircraft safely once it has landed, which may involve specific actions to secure the drone, manage its systems, and ensure that it is in a state to be safely shut down or prepared for the next flight.

Recovery procedures typically include steps for assessing the drone's condition after landing, dealing with any potential emergencies that may arise upon touchdown (such as handling battery issues or assessing for damage), and securing the drone in a designated area. Having these procedures in place helps maintain safety and efficiency in operations, which is vital for responsible drone piloting.

While maintenance schedules, fuel efficiency calculations, and aircraft design specifications are important components of drone operation, they do not directly pertain to the immediate actions taken by the pilot after completing a flight, which is why the focus is specifically on recovery procedures.
