While commands are sent from the remote pilot, what is sent from the aerial vehicle?

The correct answer is telemetry data. This involves the transmission of information from the aerial vehicle back to the remote pilot about various flight parameters and conditions such as altitude, speed, battery level, GPS location, and system health. Telemetry data is crucial for the remote pilot to monitor the performance and status of the drone during its operation, allowing them to make informed decisions based on real-time information.

In contrast, while imagery, instructions, and live video feeds may also be transmitted in certain drone operations, they do not encompass the complete scope of what the aerial vehicle sends back to the remote pilot. Imagery could include photos or visual data captured during flight, but isn't as comprehensive as telemetry data. Instructions typically refer to commands issued from the remote pilot to the aerial vehicle rather than the other way around. A live video feed provides visual information in real-time but does not encompass the critical operational data conveyed by telemetry.
