What are the top three data link priorities for the Global Hawk?

The top three data link priorities for the Global Hawk focus on ensuring the UAV's continued operational integrity and mission success in various scenarios. Real-time telemetry is essential as it provides critical information about the aircraft's systems and status, allowing operators to make informed decisions and monitor performance efficiently. Lost link contingency flight plans are crucial for maintaining control over the drone in case communication is interrupted, ensuring it can autonomously navigate back to a safe location or execute predefined emergency procedures. The nosewheel camera system, while not as critical as real-time telemetry and lost link strategies, serves to enhance situational awareness during ground operations by providing live visual data about the aircraft's immediate surroundings during mission phases.

This combination of priorities highlights the importance of maintaining communication and control over the UAV while also ensuring it can safely navigate through potential challenges during its operation. The other choices do not align as closely with the primary operational needs of the Global Hawk, which revolve around maximizing functionality and safety during missions.
