Which option correctly reflects the primary safety datalink flight requirement?

• A. Near real-time telemetry from the AV
• B. Near real-time flight commands to the AV
• C. Both near real-time telemetry from the AV and near real-time flight commands to the AV
• D. Neither telemetry nor flight commands

Answer: (C)

Two-way, near real-time communication between the UAS and the ground station is essential for safe flight. This means the safety datalink must carry both telemetry from the aircraft to the ground and flight commands from the ground to the aircraft. Telemetry keeps the operator informed about the aircraft’s status—position, altitude, velocity, battery level, sensor data, and system health. Without timely visibility into these parameters, you can’t assess risk, detect anomalies, or know when to intervene. Flight commands are what you use to control the aircraft—adjustments to course, altitude, speed, and other flight parameters. You also need this stream to implement changes in mission or to take corrective action when something unexpected happens. Having both streams in near real-time ensures you can see what the aircraft is doing and actively influence its behavior in a timely manner. If one stream is missing, you lose either visibility or control, which creates safety risks.
