How it Works Black Box Aircraft

Recently we are shocked by the leaking of the black box recordings (black box) of water falling airplane adam January 1, 2007. To the extent that the team denied that the NTSC box pilot black box recordings of conversations adam water is false. 

What is a black box? and what is its use in the aviation industry,. Black box (black box) on an airplane pilot serves to record the activities of both conversations - cockpit voice recorder (CVR), and motion-aircraft flight data recorder (FDR). CVR is a conversation in the entire data space kocpit good conversation with a co pilot pilot and the airport supervisor. 

While FDR records all aircraft flight data from aircraft altitude, speed, cabin pressure, outside air temperature, engine performance, etc.. 

The black boxes are being introduced in the 1960's. At the time recording system in the form of magnetic tape hita box that works like a tape recorder past. In 1990 the era of magnetic tape was replaced with a Solid-state Technology that uses memory chips to record data.
How a Solid-state Technology


Of FDR and CVR data stored in the memory boards in the crash-survivable memory unit (CSMU) - protective memory in the form of cylindrical . With this tool more than 700 kinds of parameter data can be stored. All data collected by sensors in the sensor plane is sent to the flight-data acquisition unit (FDAU) located in the nose of the aircraft. 

FDAU as an intermediary before the data is stored in a black box. That's why every plane crash, this is a black box in the search by the investigator, because recent data before the crash captured in this black box. Usually the data available on the black box (black box) is kept secret by the investigators for various reasons.
