What device provides a remote pilot data from the air vehicle to indicate a dangerous or irregular flight condition?

• A. Warning lights and annunciator alarms
• B. GPS receiver
• C. Inertial measurement unit
• D. Altimeter

Answer: (A)

Warning lights and annunciator alarms alert the remote pilot to dangerous or abnormal flight conditions. They are designed to trigger when a sensor detects an out-of-range value or a fault (like battery issues, motor problems, GPS loss, or unusual temperature), and they provide an immediate visual or audible cue at the ground control station. This direct alert helps the pilot take quick action, even if other data streams are being monitored. The GPS receiver, inertial measurement unit, and altimeter supply the actual data used for navigation and control, but they are not built-in alert mechanisms for hazardous conditions.
