What is a black box? How does it help solve plane accidents? Know its complete technology.

The black box is a special device that records the technical information of the plane and the conversation of the pilot.

The Air India plane crash in Ahmedabad has shaken the whole country. 265 people lost their lives in this tragic accident, including 12 crew members. Now the National Security Guard (NSG) has recovered the black box from the crash site, which is expected to reveal the real reason for this accident.

But what is this black box and how does it tell the story of a crashed plane? Let's understand in simple language.

Black Box - Name is 'Black', color is 'Orange'

First of all, let us make one thing clear the color of the black box is not black. Its color is orange so that it can be easily seen in the debris after an accident. It is installed in the strongest part of the plane so that no matter what kind of accident happens, it can remain safe.

The black box is divided into two parts.

This device has two main parts.

1. CVR (Cockpit Voice Recorder)- This part records the conversation between the pilot and co-pilot in the cockpit, warning alarms, and other sounds. That is, what the pilots were talking about before the accident, whether any alarm sounded or not, all these things are recorded in it.

2. FDR (Flight Data Recorder)- Its job is to collect technical data. Like at what height the plane was, what was its speed, which system was working or failed. All this information is stored in it.

How does the black box help in getting to the bottom of the accident?

When a plane crashes, the most important task for the investigating agencies is to find the black box. Its special feature is that even if the plane falls into water, this device keeps sending a signal for 30 days so that it can be tracked.

Once the black box is found, experts read the audio and data present in it with the help of computer systems. Pilots' conversation, sudden alarm, engine failure or other technical glitches. Records of all these are present there.

By reading these records, it is found out what caused the accident, technical fault, weather or human error.

Why is the black box so important?

The role of the black box in the investigation of plane accidents is exactly like that of an eyewitness in a crime. With its help, not only the causes are known, but safety standards are also improved to prevent such incidents in the future. Many times, airline companies have to make necessary changes based on this data.

The black box is not an ordinary device, but it contains the memories and truth of every flight. No matter how terrible the accident is, this small machine can tell the entire story of that accident. Provided it is found and understood at the right time.

Now that the black box of the Ahmedabad accident has been found, it is hoped that the truth behind this horrific accident will soon be revealed and steps will be taken to prevent such incidents in the future.
