According to AC 107-2A § 5.2.3, what characterizes an 'automated operation' for a small UAS?
Why: AC 107-2A § 5.2.3 describes an automated operation as one in which the remote pilot inputs a flight plan into the control station, which sends it to the onboard autopilot; during automated flight, flight control inputs come from components on board the aircraft rather than from the control station.
A visual observer's role is limited to observation and communication under § 107.33; a VO does not fly the aircraft from a secondary control station.
Every part 107 operation must have a remote pilot in command assigned under § 107.19; automation does not eliminate that requirement.
