Know How The Black Box Works and Functions In The Airplane – The crash of Sriwijaya Air SJ 182 in the waters of the Thousand Islands still leaves deep sorrow for the Indonesian family and nation. As of today, Tuesday (12/1/2022) the search for victims of the Boeing 737-500 type plane crash is still being carried out by a joint team.
After successfully finding several victims and plane debris, the joint team officers prioritized looking for the black box. As taken from FlightRader24, a black box is a flight recorder or flight recorder that writes all the data throughout the flight. The black box itself is a special key to find out the trigger for the plane crash.
Black boxes are very important and need to be found, because they can help investigators find out what happened before the accident. Later, the data stored on the recording device will help aviation accident investigators (Air Crash Investigators) produce flight computer video reconstructions and visualize the aircraft handling before the accident.
So, what exactly is a black box and how does it work?
The black box is the main part of the aircraft used in the aviation industry as a means of recording flight data. As taken from FlightRader24, a black box is a hard drive whose role is to record the entire history of a flight. The main body of the aircraft, invented by Australian researcher Dr David Warren, was first built in 1957.
Although given the name black box or black box, actually this element is orange. Of course, the orange color was decided to make it easier for officers to find it. Meanwhile, the naming of the black box itself stems from the history of its use during the World War II period.
As we know, the black box is the main part of the plane that is used to find out the cause of the plane crash. As taken from DW, the black box is designed to be really strong and can withstand many accident scenarios without being damaged. In fact, the black box is able to reduce the impact of a concrete wall at a speed of 750 km / hour.
The black box itself consists of 2 sides, namely the Flight Data Recorder (FDR) and the Cookpit Voice Recorder (CVR). FDR contains records of speed, vertical acceleration, fuel flow, and altitude. Meanwhile, the CVR contains conversations or conversations that take place in the cockpit throughout the flight.
In addition, the black box has an Underwater Locator Beacon (ULB) device. Later, the device will activate after the recording device comes into contact with water and can send signals from a depth of 14,000 feet. Therefore, the device can help find the black box if it falls in the sea.
If the black box is found, later investigators will take the element to the laboratory to retrieve the data in it. Then, will try to reconstruct all events throughout the flight. However, this process may take several weeks or months to complete.
After the plane crash, the investigative team will try to find the black box. The problem is the black box is a special key to find out the trigger for the accident. As taken from Netgeotv, the role of the black box is to write the flight crew’s conversation and monitor every sound that occurs in the cockpit.
In addition, the black box can record all events before the plane crash. With a black box found, some investigators will pick up sounds such as warning sounds or urgent pings. Not only that, the black box is equipped with elements that can monitor other actions carried out by the aircraft, such as flap movements on the wings and fuel measurements.
