Telemetry data relate to the UAS's health and status.

• A. Telemetry
• B. Weather data
• C. Navigation charts
• D. Battery health only

Answer: (A)

Telemetry is the data link that reports the UAS’s health and status to the operator. It streams real-time measurements from the aircraft’s systems—battery voltage and current, temperatures (including motors and electronics), flight controller status, GPS lock and position, attitude, altitude, airspeed, sensor health, and any warnings or fault codes—as well as link quality. Because it aggregates these health indicators and flight-status metrics, telemetry directly reflects how the UAS is functioning during flight and helps the operator monitor safety and performance. Weather data describe external conditions, and navigation charts are planning tools, not internal health metrics. Battery health alone is just a part of telemetry, which covers the broader picture of the aircraft’s condition.
