All you need to know about the plane's black box
If a plane meets with an accident, the most important thing to get the most accurate idea about the cause of the accident is its black box. You may have heard the word Blackbox before, but have you ever wondered what it really is and how it works? If you have that curiosity, then today's post is to satisfy it as much as possible.The data from the black box can be used to help investigators determine the cause of an accident. The information can also be used to improve the safety of future flights.
What is a black box and how does it work?
An aircraft's black box is a device that contains several parts and contains flight data recordings and cockpit voice recordings. The name of the flight data recorder part is abbreviated to FDR, and the name of the cockpit voice recorder is CVR. In the flight data recorder part, various technical information of the aircraft is stored. These data include the speed of the plane, the wind speed, how high the aircraft is flying, the fuel flow, the movement of the wheels, etc. The CVR records all audio from the cockpit, including conversations between the flight crew and air traffic control, as well as other noises from the cockpit. The FDR records data from the aircraft systems, such as altitude, speed, and engine performance. Up to 700 such parameters can be stored in the black box of large aircraft. On the other hand, all the audio/conversations in the pilot's room are recorded in the cockpit voice recorder section. In this way, the conversations and discussions of the pilot and the other crew can be heard, from which it is possible to understand the last-minute problems. the black box is located at the rear of the plane.
It's not really black, not even a box.
Although the name is 'blackbox', the black box of the aircraft is actually orange in color. This arrangement is due to the orange color being relatively easily visible. On the other hand, a black box doesn't really look like a box or box. The most visible in the structure of the blackbox is a cylinder, which is connected to a platform. It has a battery in the box-shaped structure next to the cylinder. And in the cylinder there is a memory unit. Experts in the field of aviation and aviation do not call it a black box but rather call it an 'electronic flight data recorder'.
Recording time
The flight data recorder of a black box usually stores the last 17 to 25 hours of flight data (technical/mechanical information of the aircraft). The cockpit voice recorder keeps a record of the last 2 hours of conversation between the pilot and everyone in his room. If there is no solid state memory drive, this recording time in magnetic storage can be even 30 minutes.
It's incredibly strong
The blackbox is very strongly made. Its structure is made of lithium or stainless steel. If the black box is smashed at a speed of 750 km/h on a concrete wall, it will also survive. It can remain intact for at least 5 minutes with a weight of 2.25 tons in steady condition. At a maximum temperature of 1100 degrees celsius, the blackbox will survive for up to an hour without any damage. Even underwater pressure at a depth of 6,000 meters, a black box can remain intact. Another important feature is its water-sensor. When the blackbox's special sensor comes in contact with water (falling into the sea/river), it sends a signal every second, from which the rescue team can understand its location and pick up the device. However, as long as the blackbox's battery works, it can send this signal. normally, a black box can send signals for up to a maximum of 30 days. And this signal can come up to a maximum of 4 kilometers from the bottom of the water.
Retrieving information from Blackbox
After the black box of a crashed plane was found, the work of retrieving its information began. special software and devices are needed to take data from storage and analyze it. All in all, it may take a few weeks. it may even take a few months.
The black box of the future
Work has been done to keep audio as well as video recordings in the future to improve the black box and its usability. Apart from recording, there is also an idea to send it to a center on the ground immediately. As a result, you don't have to wait for the blackbox to get the information. However, it has not yet seen the face of usable reality. This can be possible with the help of artificial satellites. Apart from this, there is also the idea of having more than one black box in place of one in the same plane.
It's not just on the plane!
Not just airplanes, but other vehicles such as cars can also have black boxes called event data recorders.
