Black Box – Invention – Technology
The cockpit voice Recorder and flight data Recorder of the Indian Air Force (IAF) chopper that crashed with CDS General Bipin Rawat and others were recovered. About: – A black box, technically known as an electronic flight data recorder, is an orange-colored heavily protected recording device placed in a flight. It is used to investigate the details of the events immediately preceding an accident.
Black- boxes are compulsory on any commercial flight or corporate jet where they are usually kept in the tail of an aircraft, where they are more likely to survive a crash. It usually takes at least 10-15 days to analyze the data recovered and then the black boxes. Black boxes are also used in vehicles other than planes like Railways, cars, etc.
Invention:- Australian Scientist David Warren was the first to build an FDR/CVR prototype in 1958. Parts:- The black B0x is made up of two separate pieces of equipment. The flight data Recorder FDR and a cockpit voice recorder.
Technology:- Older black b0xes used magnetic tapes, a technology that was first introduced in the 1960s. Magnetic tapes work like any tape recorder. These days, black boxes use solid-state memory boards, which came along in the 1990s. Solids state memory boards use stacked arrays of memory chips and are stronger.
The FDR contains, crash survivable memory units which are engineered to withstand extreme heat, jarring crashes, and tones of pressure. To make black b0xes Discoverable in situations where they are underwater, they are equipped with a Beacon that sends out ultrasound signals for 30 days.
