Flight Data Recorder (FDR)

A Flight Data Recorder (FDR) is a device installed in aircraft to continuously record vital flight information, such as speed, altitude, heading, engine performance, and control inputs. Often called a "black box," it helps accident investigators determine what happened during a flight by providing detailed data before and during incidents. Designed to withstand crashes and extreme conditions, the FDR's data is crucial for improving aviation safety, accident analysis, and understanding aircraft performance. Its recordings are typically stored securely and can be retrieved after an incident to assist investigators in improving flight safety standards.
