Air India: The authorities found one of two black boxes to help reveal what caused the tragic crash of Air India, killed by 12 June over 240 people.
The black cabinet at the back of the aircraft was found and safely guarded. The black cabinet was found on the roof of the building on which the aircraft of the aviation India crashed. The team for investigating air accidents (AAIB), which helped 40 staff from the Gujarat government, found a black box. The General Directorate for Civil Aviation will collect recordings analysis facilities.

According to civil aviation officials, the second black cabinet, which was fastened in front of the aircraft, is still found.
What is a black cabinet?
The black cabinet is a small machine that records information about the aircraft during the flight. It is basically a flight recorder with origin in the early 50 years. This bright orange or yellow rectangular box is created to withstand explosion, fire, water pressure and high -speed accidents.
The box was invented by Australian scientist David Ronald de Mey Warren and is useful in revealing the cause of the aircraft accident. Warren died in 2010.
The black cabinet has two recorders, a voice recorder for pilot voices and cockpit sounds and a separate flight recorder.
How does a black cabinet last?
The black cabinet is made of thick substances such as steel or titanium, and is insulated from factors such as extreme heat and cold. It is intentionally placed towards the tail end of the aircraft, where the impact of the accident is usually the smallest.
How does this help in the investigation?
Two black cabinets of any aircraft are a voice recorder of the cockpit (CRV) and the Flight Data recorder (FDR). These two basically record flight information and help reconstruct events leading to the aircraft crash.
The CRV records radio transmissions and other cockpit sounds, including conversations between pilots and engine sounds. The FDR records more than 80 different types of information such as altitude, flight speed, flights, vertical acceleration, playground, roll, autopilot condition, etc.

Analysis of data obtained from black cabinets after an accident usually takes 10-15 days.
The black cabinet is an important tool that knows what has led to a tragic air aircraft after take -off from Ahmedabad Airport on Thursday afternoon. In principle, they reveal the basic reason or reaction of Mayday call or any warning aircraft.
The Air India B787 caused the air traffic control call (ATC) immediately after take -off. However, according to the statement of the General Directorate for Civil Aviation (DGCA), he did not answer the ATC call to the aircraft.
So the last road from the crew of the unfortunate aircraft was “Mayday, Mayday …”, followed by radio silence.
What is inside the black cabinet?
The black cabinet includes the four main parts that are:
-A interface designed to repair the device and facilitate recording and playback
-An underwater locator lighthouse.
-A ‘Crash Survivable Memory Unit’ made of stainless steel or titanium that is designed to endure the power equivalent to 3,400 times greater gravitational force
-Cip recording is on the circuit board.
Investigations in the past?
Investigating the Kozhikode aircraft in 2020 in the Air India Express Flight 1344 was dependent on the recordings of the black cabinet, which revealed it was due to a pilot error.
The 2015 German German crash was another incident that was investigated by recordings of the black cabinet.
Black cabinet history
Warren was admitted to a special team in 1953 to analyze the medium air explosions to experience the world’s first commercial aircraft, de Havilland Comet, according to the International Civil Aviation Organization (ICAO). The flight was launched for commercial operations in 1952, but in the early years it recorded major accidents.
This idea has encountered initial resistance, even from pilots who claimed that the recorders would be used to spy on the crew. In 1956, Warren created a prototype called Arl Flight Memory Unit, which allowed storage of up to four hours of voice data and in the instrument.
In 1963, after two fatal air accidents, Australia became the first country to make flight recorders a compulsory legal requirement.
Why is it called a black cabinet?
The last road from the crew of the unfortunate aircraft was “Mayday, Mayday …”, followed by radio silence.
According to Airbus website before Warren, French engineer François Husenot began working on a data recorder at the age of 30. This equipment had sensors that optically project around 10 parameters on a photo film.
