Which of the following describes the function of communication links in an sUAS?

Communication links are crucial for the operation of small Unmanned Aircraft Systems (sUAS). Their primary function is to facilitate remote operation and control of the aircraft. These links enable the pilot to transmit commands to the sUAS, such as maneuvering, altitude adjustments, and other operational control functions. Additionally, communication links allow for the transmission of telemetry data back to the operator, providing real-time information about the drone's status, location, and other critical parameters.

In contrast to the correct choice, establishing flight routes is not solely dependent on communication links, as flight planning can occur independently of live communication. Radar detection is typically managed by separate onboard systems rather than being a function of the communication links themselves. Filing flight plans is a regulatory requirement and involves paperwork with the FAA, separate from the communication systems employed during the operation of an sUAS. Thus, the essential role of communication links is to ensure effective control and monitoring of the aircraft during flight.
