The Flight Data Recorder (FDR), also known as the accident data recorder, is an essential device for recording specific performance parameters of aircraft. These devices, often referred to as "black boxes," play a crucial role in the investigation of aviation accidents and the analysis of air safety issues. The FDR not only records technical data but can also be used in conjunction with a Cockpit Voice Recorder (CVR), which captures conversations in the cockpit as well as radio communications. The construction of these devices is particularly robust to withstand extreme conditions such as high-speed impacts and intense fires. To enhance visibility in the wreckage, FDRs are coated with heat-resistant, bright orange paint and are typically mounted in the rear section of the aircraft, where they have the best chance of survival in a severe crash.
