Who controls an unmanned aerial vehicle during operations?

The correct choice is based on the fact that unmanned aerial vehicles (UAVs), commonly referred to as drones, are primarily operated by ground control operators during missions. These operators are responsible for directing the UAV, making real-time decisions, and managing its flight path to ensure it operates safely and effectively in its designated environment.

Ground control operators utilize various command and control technologies to communicate with the UAV, issuing commands that can adjust the flight operations according to the mission's needs, environmental conditions, or specific tasks that require human oversight.

While pre-programmed automation plays a role in UAV missions, particularly in executing certain predefined functions or maneuvers without human intervention, it does not account for the dynamic decision-making required during operations. Similarly, while onboard computers control various flight functions, they rely on the commands issued by the ground control operator. Having a pilot onboard is not applicable in the context of unmanned aerial vehicles, as these systems are designed to operate without a human pilot physically present in the vehicle.
