What tool does a remote pilot use for communication with the UAS?

The tool that a remote pilot uses for communication with the UAS is the telemetry interface. This interface allows for the exchange of crucial data between the unmanned aircraft system and the operator on the ground. It facilitates the transmission of flight data such as altitude, speed, orientation, and battery status, which is essential for the pilot to monitor the UAS's performance throughout its operation.

The telemetry interface operates by sending information back and forth through radio frequencies, enabling real-time communication. This connectivity is vital for safe and effective control, ensuring that the remote pilot can make informed decisions based on the data received from the UAS.

While options like radio frequency modulation and remote control joystick play roles in the overall operation of the UAS, the telemetry interface specifically focuses on the data exchange aspect of communication, differentiating it as a critical tool for pilots managing the UAS's operations. Visual line of sight is related to the pilot's ability to see the aircraft and isn't a communication tool per se; instead, it's a regulatory requirement for maintaining situational awareness.
