Plane crash black box: It often happens in aircraft accidents that the debris of the plane breaks down badly and it remains only as a pile of metal and ash. Despite this, one thing that is always found safe is the black box of the aircraft. This is a device that protects the data even after an accident. Knowing about the black box, we can understand how it is safe despite a big accident and what special technology is implemented on it.

The black box is made by mixing two important devices: CVR (Cockpit Voice Recorder) and FDR (Flight data recorder). The main objective of these two is to record the technical data of the aircraft and pilot’s conversation. How the black box is manufactured, why it is safe in accidents and what are its important tasks, let’s know-

Features of Black Box Building

The black box is produced with very strong and special material, so that it can withstand any type of accident, fire, water and heavy pressure.

1. Exterior Cover made of strong material

The outer part of the black box is made from titanium or stainless steel. This metal is very strong and can tolerate any kind of shock or pressure.

2. Security from fast fire

The black box has been designed in such a way that it can be safe for 60 minutes in a temperature fire up to 1100 ° C. This means that even if the aircraft caught fire, the data of the black box will be safe.

3. Heavy pressure and water prevention

If the aircraft falls into the sea, the black box can face pressure and water up to a depth of 20,000 feet. Its design also protects it from the circumstances that are very challenging.

4. Inside security layer

There are many layers such as special insulation, thermal protection and shock absorber inside the black box, which protect the black box from accidents and protect the data.

Way of Black Box Search

After aircraft accidents, an underwater locator beacon is installed to find the black box. It sends a beacon signal and this signal remains active for about 30 days. This helps the search team to locate the black box, especially when the aircraft has fallen into the water.

Importance and need of black box

Black box aircraft is the biggest witness to the truth of accidents. With its data, search agencies can find out what the pilot said before the accident, what type of technical fault was and what happened in the last moments. Based on these important information, steps are taken to prevent future accidents.
