Which device records flight data during an aircraft incident investigation?

• A. Digital Flight Data Recorder (DFDR)
• B. Cockpit Voice Recorder (CVR)
• C. Black box
• D. GPS unit

Answer: (A)

The main idea is that flight data is captured by a dedicated recorder that logs numerical aircraft parameters during flight. The device that records this data is the Digital Flight Data Recorder. It collects numerous metrics such as airspeed, altitude, heading, vertical speed, attitude, engine parameters, and control surface positions, providing a detailed timeline of how the aircraft performed. This information lets investigators reconstruct the flight profile and pinpoint what happened leading up to any incident. The cockpit voice recorder stores pilot and cockpit communications, which is valuable but separate from the flight data; the term black box is a general nickname for the combined system, not the specific data recorder. A GPS unit stores position information, but it does not capture the full suite of flight parameters used in investigations.
