Flight Data Recorder (FDR)

Flight Data Recorder – the actual name of the infamous “black box” (which is actually orange rather than black). The FDR records a large set of flight parameters. Its purpose is to keep those parameters saved in case of an accident, particularly a crash. The FDR is designed in a way which should allow it to withstand the crash forces, immersion in water, etc. It is also equipped with an underwater locator beacon, which helps search and rescue teams to locate the unit under water.
