History of Flight Recorders
Efforts to require crash-protected flFoil Recorderight recorders date back to the 1940s. The introduction of Flight Data Recorders (FDR), however, experienced many delays. That’s because technology could not match the design requirements of a unit that could survive the forces of an aircraft crash and the resulting fire exposure until 1958, when the world authorities approved a minimum operating requirements for an FDR. This was about the beginning of the so-called “Jet Age,” with the introduction of such aircraft as the Boeing 707, Douglas DC-8 and the Caravelle. The initial requirement of these newly mandated data recorders was to record the actual flight conditions of the aircraft, i.e., heading, altitude, airspeed, vertical accelerations, and time.
