What's inside a Air Plane Black Box?

What's inside a Air Plane Black Box? The search for from Air France 447, which crashed into the middle of the Atlantic Ocean in June, has been a major news story globally and Airbus says it is willing to spend up to 20 million euros to recover this invaluable device. Device recovery from black boxes (formally Flight Information Data Recorders) is the ultimate in : a plane will plunge into the sea leaving only destruction and no survivors in its wake. Yet, once is retrieved it is still possible for experts to save this data and discover what went wrong on the flight, but why is a black box able to achieve the impossible and survive a crash which annihilates everything else? The name, black box, describes a system which is difficult for users to access and the process is tricky even for experienced professionals. The unit, which is very like one in a home or office computer, is hidden in three almost indestructible boxes: a thermal box is placed inside an insulation box which is then placed in a titanium or steel box and then stored in the tail of the aircraft to protect it from high impact. The unit is shorter than a 30cm ruler and is painted orange so that it is more easily recovered in the ocean or the wilderness. This defensive shell can protect the unit from an impact of 3,400 times the force of gravity, temperatures as high as 1, 100 degrees Celsius and crushing by 2,300 Kilograms of force. The in the box is also recoverable after has been lying in an ocean depth of 6.5 kilometers for a month. The box records all data about the current state of the plane. This includes its control position, engine information, general performance and sometimes conversations in the cockpit, radio communication and ambient sounds. is recorded for approximately 20 hours in a continuous loop in flight and is then transferred to a solid state recorder for evaluation with specialised accident investigation equipment after recovery. The data recovered from a black box reveals the cause of the accident; this allows airlines and plane manufacturers to determine whether the accident was caused by pilot error or faulty parts. As a result, steps can be taken to prevent a similar accident in the future and provides closure to victims' families.
