Which unit forwards sensor data to the Black Boxes?

Which unit forwards sensor data to the Black Boxes?

• A. Inertial Reference Unit
• B. Flight Management System
• C. Air Data Computer
• D. Flight Data Acquisition Unit

Answer: (D)

Sensor data is gathered by multiple avionics units, but it is routed through a central hub before being recorded. The Flight Data Acquisition Unit collects inputs from sensors such as the inertial reference unit and the air data computer, formats and timestamps them, and then forwards this data to the Flight Data Recorder (the black box). This makes it the essential bridge between on‑board sensors and the recorder. The inertial reference unit provides attitude and motion information to navigation and autopilot systems, but it doesn’t directly feed the black boxes. The air data computer generates air data like pressure, altitude, and speed, supplying various systems, yet the logging path goes through the data acquisition unit. The flight management system uses data for navigation and flight planning and isn’t the primary conduit to the recorder.
