Black box of Ahmedabad plane crash found
One of the two black boxes of the Air India plane that crashed in Ahmedabad on June 12 has been found, which will help in finding out the cause of the plane crash in which 241 people on board died. According to media reports, the black box was found in the rear part of the plane and has been kept safely. A Gujarat ATS official said that ‘we have recovered the digital video recorder (DVR) from the wreckage of the plane.’
According to the report, the black box installed in the front part of the plane has not been found yet.
The information recorded in the black box is considered very important to find out the reasons behind the plane crash. Let us know what is a black box and how it works.
What is a black box?
The small box placed in one corner of the plane is called a black box. It is a small machine that records information about the plane during flight. The black box is mainly a flight recorder. It consists of two devices – Cockpit Voice Recorder (CVR) and Flight Data Recorder (FDR). The CVR records radio transmissions and sounds such as the pilot’s voice and the sound of the engine. Through this, the investigating officers can detect the engine speed and other system faults.
The black box is made of strong materials such as steel or titanium. It remains safe even in a severe fire. The black box is placed towards the rear of the aircraft, where the impact of the accident is usually the least. This orange or yellow rectangular box can withstand explosions, fire, water pressure and high-speed accidents.
How does the black box help in the investigation?
Both the black boxes installed in the aircraft – CVR and FDR record information about the flight. This helps in preventing the plane crash again. The CVR records radio transmissions and other sounds in the cockpit, including conversations between pilots and the sound of the engine. While the FDR records more than 80 different types of information related to the ship, such as altitude, wind speed, flight direction, autopilot status, etc.
