Flight data recorders, commonly known as black boxes, are devices installed in aircraft to capture and store critical flight information. They record data such as altitude, speed, and heading, as well as cockpit conversations. This information is vital for investigating accidents and improving aviation safety. There are two main types of flight data recorders: the flight data recorder (FDR) and the cockpit voice recorder (CVR). The FDR tracks various flight parameters, while the CVR captures audio from the cockpit. Both devices are designed to withstand extreme conditions, ensuring that data can be retrieved even after a crash.
