What is the main goal of telemetry in aviation?

Telemetry in aviation is primarily focused on providing real-time data about the aircraft's status. This function is crucial for monitoring a variety of performance metrics such as altitude, speed, heading, and system health. The real-time aspect allows operators to make informed decisions during a flight, enhancing safety and efficiency.

Real-time data transmission enables ground control and operators to respond promptly to any anomalies or changes in the flight parameters. This capability is particularly vital in unmanned aerial systems (UAS), where understanding the vehicle's status at all times is essential for safe operation.

While telemetry can also support functions related to other options—like controlling flight dynamics indirectly or transferring video feeds—it is fundamentally about the transmission of performance and status data which informs operational decisions. Thus, the primary goal of telemetry aligns best with providing real-time updates about the aircraft.
