Which of the following is NOT a role that a control station can serve?

A control station primarily serves as the hub for various operations necessary for the effective functioning of Unmanned Aircraft Systems (UAS). Among its roles, command and control of the UAS is a fundamental responsibility, allowing the operator to manage the drone's flight and navigate it as required. Flight planning and management is also crucial, as the control station facilitates the preparation and execution of the mission plan, ensuring that the UAS operates within its specified parameters.

Additionally, the storage of flight data is an important function, as it allows operators to access historical information regarding the drone’s performance, sensor data, and other crucial metrics for analysis and compliance purposes.

In contrast, while relaying data for visual line of sight operations is important, the control station itself does not inherently serve as a relay for extended VLOS data links; rather, this role is typically fulfilled by other systems or equipment that enhance communication over longer distances. This option does not accurately represent a primary function of a control station, thereby making it the distinct choice that does not align with the fundamental roles.
