What must a Remote Pilot do if they intend to operate in controlled airspace?

To operate in controlled airspace, a Remote Pilot is required to obtain both a Remote Pilot Certificate and airspace authorization, making this the correct answer.

The Remote Pilot Certificate is essential because it validates that the pilot has the necessary training and knowledge to operate a drone safely and in compliance with regulations. Moreover, airspace authorization is mandatory due to the complexity of controlled airspace, where various types of aircraft operate, typically at different altitudes. This authorization can be obtained through the FAA's LAANC (Low Altitude Authorization and Notification Capability) system or by applying directly for permission from the appropriate air traffic control facility.

This process ensures that the safety of all airspace users is maintained by preventing potential conflicts between drones and manned aircraft. Without these precautions and proper certification, a Remote Pilot would not be compliant with FAA regulations, which are in place to ensure safe operations.
