To get the most accurate idea about the cause of the accident when the aircraft faces an accident, the most important thing that is needed is its black box. You may have heard the word Black-Box before, but have you ever wondered what it really is and how it works? If you have that curiosity, today’s post to meet it as soon as possible.
Black Box Key And How It Works
Biman Black-Box is a device that has a number of parts and has recorded flight data recording and cockpit voice recording. Name of the flight data recorder briefly is the FDR, and the cockpit voice recorder’s name is CVR. In the Flight Data Recorder section, technical information of the aircraft was a store. These include the speed of the plane, the speed of the wind, how high the plane flies, the fuel flow, the movement of the wheels, etc. The up to 700 such parameters can store in the big box of the big airplane. In the cockpit voice recorder, on the other hand, all audio/speech records of the aircraft carrier’s room record. It allows listeners and talk of pilots and other crew, which can understand from the last moment’s problems. The Black Box is lock on the back of the aircraft.
This Is Not Black Either, Nor Even A Box
But the black box of the aircraft is actually black orange black box. Because the orange color is relatively visible, this system is very visible. On the other hand, the black box does not actually look like a box or box. The most visible of the black-box structure is a cylinder, which is connected to a platform. The box-sized framework has a battery inside the cylinder. And the memory unit is on the cylinder. Airplane and aviation experts call it ‘black box’ rather than ‘electronic flight data recorder’.
Recording Time
The Black Box Flight Data Recorder usually saves the last 17 to 25 hours of flight data (technical/mechanical data of the aircraft). Cockpit voice recorder puts the last 2 hours record of the pilot and everyone in his room. If you do not have a solid-state memory drive, this recording time maybe 30 minutes in magnetic storage.
It’s Incredibly Strong
The Black-box is very strong. Its structure is made of lithium or stainless steel. If a black box is thrown at a speed of 750 kilometers/hour on a concrete wall, it will also survive. It can remain at least 5 minutes intact with a weight of 2.25 tons. Black-box will survive without any type of damage to an hour at a maximum of 1100 degrees Celsius. A black box can be intact, even under the water pressure of 6,000 meters depth.
Another important feature is its water-sensor. When the special sensor of the Black-box comes in contact with water (in the sea/river), it sends a signal every second, from which the rescue team can pick up the device after understanding its position. However, as long as the Black-box battery works, it can send this signal. Generally, a black box that can send the maximum signal up to 30 days. And this signal may come from the bottom of the water up to 4 kilometers.
Recover Information
After finding a black box of a crashed plane, the information was rescued. Special software and equipment are needed to analyze data from storage. All in all, it may take weeks. It may take even a few months.
Future Black Box
To improve the black box and its usability, it has been done to keep video recordings in the future as well as audio. In addition to recording as well as instantly sent it to a center in the country, the idea came. As a result, you do not have to wait for the black box to get the information. Although it still does not see the face of usable reality. This can be possible with the help of artificial satellite. There is also a similarity to putting multiple black boxes in one place on the same plane.
Not Just On The Plane!
Not only the aircraft but also other vehicles such as the car may also have black boxes called an event data recorder.
