True or False: The Ground Data Terminal (GDT) facilitates communication with airborne systems equipped with a datalink.

The statement is true. The Ground Data Terminal (GDT) serves as a communication hub between the ground control and the airborne systems that are equipped with a datalink. This communication is essential for operational effectiveness, allowing the ground crew to send commands to the UAS (Unmanned Aircraft System) and receive telemetry data in return. The GDT is designed to facilitate real-time communications, which is crucial for monitoring the flight, ensuring safety, and making necessary adjustments during operations.

The effectiveness of the GDT is not limited to specific phases of flight, such as takeoff or being in close proximity to the aircraft, which is why those alternatives do not accurately reflect the GDT's capabilities. Instead, its functionality is maintained throughout operation, as long as the system is within range and properly configured, enabling ongoing data exchange regardless of the aircraft's position and flight phase.
