According to FAA regulations, unmanned aircraft are generally allowed to operate up to 400 feet AGL in uncontrolled airspace without special authorization.
The FAA requires that the registration certificate for the UAS be available to the remote pilot during operations to ensure compliance with regulatory requirements.
The Remote Pilot in Command (RPIC) has the overall responsibility to ensure the safety of the flight operations, which includes compliance with all applicable regulations and safe conduct of the flight.
A visual observer is required when operating beyond the visual line of sight (BVLOS) to ensure the UAS is safely operated and to help the remote pilot maintain situational awareness.
The FAA requires remote pilots to check visibility and cloud cover to ensure safe flight operations. Visibility must be at least 3 statute miles, and the UAS must remain at least 500 feet below and 2,000 feet horizontally away from clouds.
