Investigation agencies are now looking for the real causes of the accident, and the most important part of this investigation is - black box. The same device records the activities of every moment of the aircraft and helps to understand the causes of the crash. But the question in the minds of the common people is that what is this black box? How does it record all the plane things? Let's know every important information related to it.
What is a black box?
The black box is actually an electronic device, which is fitted in the aircraft in such a way that it remains safe in any accident. Its real name is:
- Cockpit Voice Recorder (CVR)
- Flight data recorder (FDR)
- Together, these two are called "black boxes" in common language. It records everything from the technical activities of the aircraft to the conversation of the pilot and co-pilot.
What does black box do?
Black box does two main functions
- CVR (Cockpit Voice Recorder): It records pilot and co-pilot interactions, alarm, engine voice and other sounds in the aircraft's cockpit.
- FDR (flight data recorder): It records more than 88 parameters continuously for the aircraft speed, ultitid, engine status, door status, positions of controls etc. This recording is updated every second and this data is saved in a strong memory unit.
Is the black box really black?
Although it is called the "black box", its color is usually orange or bright red. This is so that after a crash it can be easily visible in the debris. There are also reflective strips on top of it.
How does the black box survive in an accident?
The black box is specifically designed in such a way that it can bear excessive temperature (up to 1100 ° C), dark water (up to 20,000 feet), and tremendous collision (up to 3400 g-force). It also has an underwater locator beacon (ULB), which keeps sending signals for 30 days when falling into the water.
How does the black box help in investigation?
When an aircraft is a victim of an accident, with the help of data from the black box, it is known what the pilots were doing in the last few minutes, what technical problems came in the aircraft, and which alarms were active.This information is very helpful in finding the cause of an accident and avoiding such incidents in future.The black box is the most important security device of any aircraft, which works to expose the truth after the accident. It is almost impossible to reach the real cause of an accident without it. The role of a black box is most important in cases like Air India Crash, because it not only responds, but also a lesson for the future.
