Today's unmanned aircraft systems (UAS) are equipped with ________ that continuously monitor the aircraft's altitude, attitude, location, and speed.

• A. GPS receivers
• B. Visual observers
• C. Manual flight logs
• D. Advanced electronic flight control systems

Answer: (D)

Modern UAS rely on an advanced electronic flight control system that continuously monitors altitude, attitude, location, and speed. This system combines signals from sensors like the IMU (which tracks orientation and motion), GPS (for position and often speed), a barometer (for altitude), and other sensors to know the aircraft’s exact state in real time. It runs autopilot logic that stabilizes the aircraft, follows the mission path, and makes immediate adjustments to motors or control surfaces to maintain desired altitude, orientation, and speed. GPS receivers provide location data but don’t alone track attitude or provide the full real-time flight state. Visual observers are external and not automatic, and manual flight logs are records, not live monitoring. So the best description is the advanced electronic flight control system.
