The uplink, which describes the portion of the data link that transmits commands and flight plan changes from the ground control station to the air vehicle, is also known as which of the following?

The term "uplink" is specifically used to describe the channel that carries commands and updates from the ground control station to the unmanned aerial system (UAS). This is integral for maintaining control over the air vehicle during flight operations. Referring to this as a "Command Link" accurately captures the essential function of the uplink, which is to transmit commands.

While the other terms like "Control Link" and "Data Link" are related and sometimes used interchangeably in various contexts, they may not specifically emphasize the aspect of command transmission. "Control Link" can imply a broader range of controls but does not distinctly highlight the uplink's role in sending command-specific telemetry. "Data Link" generally refers to the entire communication channel involving both uplink and downlink (the return communication from the UAS back to the control station).

"Wireless Link" refers to the type of technology used for transmitting signals and is too generic. Thus, calling the uplink a "Command Link" is the most precise and appropriate term in this context, focusing on its primary function of delivering operational commands to the air vehicle.
