Air India Express flight from Dubai to Kozhikode when flight AXB1344, B737 coming from Dubai to Kerala crashed while landing. At the time of the accident, there were 190 passengers and six crew members on the plane. So far 18 deaths have been confirmed. The Air Craft Accident Investigation Bureau (AAIB) has also got a black flight box. It is now possible to find out what happened before the crash. But very few people will know what is a black box?

It works like a black box or flight recorder. It keeps track of the aircraft from moment to moment. It is a device to closely record all movements that occur during a flight in any aircraft. It fits the rear of the aircraft. Would like to explain why the 'black box' in the aircraft survives safely despite the plane crash. It is made of titanium which is considered to be a very strong metal. The black box is sealed in a box of titanium. That is why even if the black box falls from a high height, it is not harmed.

Flight data recorder: It records 88 types of data including the direction of the aircraft, altitude, how much fuel is there, speed, movement, cabin temperature, etc. It collects over 25 hours of recorded information. The black box can withstand temperatures of 11000 ° C for one hour and the device inside it can tolerate temperatures of 260 ° C for up to 10 hours.

Cockpit Voice Recorder: This recorder, recorded in a black box, records the sound of 2 hours of flight. It records the sound of the engine, the sound of an emergency alarm, the sound of the cabin and the sound of the cockpit, and the interaction between flight control. So that it can be known how the atmosphere of the aircraft was before the accident.

Black boxes can work without electricity for 30 days. When it is separated from the plane, every second it emits a beep. This wave originates for 30 days. Which search teams can easily find within a radius of 2 to 3 kilometers. It keeps sending waves even from 15000 feet deep sea.
