DFDR (Digital Flight Data Recorder)

A Digital Flight Data Recorder (DFDR) is an advanced device installed in aircraft to electronically record critical flight parameters, such as speed, altitude, heading, and engine performance, throughout a flight. Unlike traditional recorders with physical tapes, a DFDR continuously captures and stores data digitally, making retrieval and analysis more efficient. This information helps investigators understand what happened during a flight, especially in case of an incident or accident. It also supports ongoing maintenance and safety improvements by providing detailed, accurate records of aircraft operations.
