Black Box Recovered
The cockpit voice Recorder and flight data Recorder of the Indian Air Force(IAF) chopper that crashed with CDS General Bipin Rawat and other were recovered.
About:- A black box, technically known as an electronic flight data recorder, is an orange coloured heavily protected recording device placed in a flight. It is used to investigate the details of the events immediately preceding an accidents.
Black- box 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 is usually takes at least 10-15 days to analyses the data recovered then the black boxes.
Black boxes are also used in vehicles other then planes like Railways, cars etc.
Invention:- Australian Scientist David Warren was the first to build a FDR/CVR prototypes in 1958.
Parts:- The black boxes is made up of two separate pieces of equipment. The flight data Recorder FDR and a cockpit voice recorder.
Technology:- Older black boxes used magnetic tapes, a technology that was first introduced in the 1960's . Magnetic tapes works like any tape recorder. These days, black boxes use solid state memory boards, which came along in the 1990's . Solids state memory boards use stacked arrays of memory chips, and stronger. The FDR contains, crash survivable memory units which are engineered to withstand extreme heat, jarring crashes and tones of pressure. To make black boxes discoverable in situation where they are under water, they are equiped with a Beacon that sends out ultrasound signal for 30 days.
