You Know What That Black Box?

     Many of us all know if Black box is a box that "tell", said storytelling because the data stored in it stored all the required flight activity investigators in uncovering what events led to an aviation accident occurs. Might be called black to connote "Black" as a tragedy.

     But actually the Black Box on the plane is not black, but the Orange or Red (painted bright colors in order to obtain a high level of visibility or attention Indonesian shocking pink). Black box first started appearing in 1950 and began to be required in 1960.

     "Black box" is a general term for commercial aircraft recorder (large commercial aircraft carrying two black boxes in it). Flight Data Recorder (FDR) records a variety of parameters associated with the operation and flight characteristics of the aircraft. Cockpit Voice Recorder (CVR) recording sound crew, engine noise, and other sounds in the cockpit.

     All large-bodied commercial aircraft and commercial aircraft that are smaller or owned corporation (company), as well as private aircraft are required by law to carry one or both of these boxes, which generally cost between $ 10,000 and $ 15,000. Black Box itself is resistant to high temperatures up to 1,100 C. Crash Survivable Memory Unit (CSMU) contains a memory board surrounded by thermal insulation and steel armor that can withstand the impact of an accident thousands of times the force of gravity and survive in the sea at a depth of 14,000 20,000 feet (4.270 m-6096 m).

     In addition to facilitate the search for the position (especially underwater search) or aircraft black box, equipped underwater locator beacon that works is constantly emits ultrasonic recorders and signal can reach the surface from a depth of 14,000 ft. Modern design black box arranged by a group called the International Civil Aviation Organization (ICAO).

     FDR than I mentioned above also recorded data from a number of sensors to monitor information such as acceleration, speed, altitude, cockpit control positions, thermometers, engine gauges, fuel flow, surface set positions, autopilot status, switch positions, and a variety of other parameters. Most parameters are recorded several times per second but some of FDR can record bursts of data at a higher frequency when the input changes rapidly. Black Box is itself located at the rudder, or tail plane with an estimate when a crash occurs then the part is relatively intact and not destroyed.
