Flight data recorders, also known as black boxes, are critical devices that record flight data and cockpit conversations. In addition to black boxes, there are several other synonyms that can be used to refer to these important devices. Some of the commonly used terms include cockpit voice recorders, flight recorders, data recorders, and event recorders. While the primary purpose of these devices is to capture information, using proper terminology is important in aviation and aerospace industries. Black boxes, in particular, have been in use since the 1950s and continue to play an important role in understanding and investigating aviation accidents.
