Which device is commonly used alongside DFDR and CVR in aircraft accident investigations?

• A. Black box
• B. GPS unit
• C. Radar
• D. Satellite phone

Answer: (A)

A central idea in aircraft accident investigations is uncovering what happened from recordings kept on the aircraft. The devices that capture and preserve this information are known as the aircraft’s black boxes. The Digital Flight Data Recorder and the Cockpit Voice Recorder are the core components of that black box system. They provide the flight parameters, control inputs, engine data, and cockpit communications needed to reconstruct the sequence of events and determine probable causes. While other tools like GPS, radar, or satellite communications can help add context, they do not replace the critical, on-board data and audio captured by the black boxes.
