Which of the following are primary safety datalink flight requirements concerning UAS implementation into the NAS?

• 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 data exchange is essential for safe UAS integration into the National Airspace System. Telemetry gives ongoing status details from the vehicle—its position, altitude, velocity, attitude, battery and health data—so operators and the system know exactly where and how the UAS is behaving. Flight commands provide the ability to steer or alter the vehicle’s path, speed, and altitude, and to initiate emergency actions when needed. This combination creates a real-time feedback loop that supports situational awareness, safe separation from other traffic, and the ability to follow ATC instructions. Without telemetry, you lack visibility into the vehicle’s state; without flight commands, you lack the means to control or rapidly adjust its behavior. Therefore, both near real-time telemetry and near real-time flight commands are required.
