It is one of the two devices commonly referred to as an aircraft black box, the other being the CVR (Cockpit Voice Recorder). Flight Data Recorder (FDR) Modern FDRs capture thousands of data points per second, making them vital for: Accident investigation Flight safety analysis Aircraft performance monitoring Although popularly called a “black box,” an FDR is actually bright orange to make it easier to find after a crash. History of the Flight Data Recorder The concept of the FDR began in the 1950s, with early versions recording only basic altitude and speed data. Over the decades, FDR technology evolved significantly: 1950s: Magnetic tape recorders 1970s: Multi-channel crash-survivable recorders 1990s: Digital solid-state memory systems Present: Ultra-high-capacity devices with real-time monitoring support Today, ever...
