Overview of the Plane’s Black Box

Black Box is a general term used by the aviation world to record data while the aircraft is flown.

Although the name is black box, but in reality this Black Box is lit orange. This is intended to be easily identified in search operations. In the Black Box there are two important parts that are useful to help investigate in the event of an accident,

An important part of a Plane’s Black Box

The Black Box consists of two important sections including the CVR (Cockpit Voice Recorder) which contains recordings of conversations that take place in the cockpit of the aircraft such as conversations between the pilot and the Co-Pilot. In the cockpit of the aircraft when communicating between crew, ground supervisors, and other aircraft as well as recording sounds such as radio transmissions and automatic alarms. With this CVR recorded data can strengthen the results of investigations when accidents occur.

Then there is also the FDR (Flight Data Recorder) section that serves to record a variety of data about all aspects of the aircraft. With this FDR, we’ll get a record of the data during the flight. Starting from the details of the time, altitude, air speed, engine rotation, radar, autopilot and direction of the aircraft.

By analyzing the data from FDR, we can find out the chronology of the occurrence of plane accidents technically.

The in-flight Black Box is equipped with an Underwater Locator Beacon (ULB) that is immediately activated after the recorder comes into contact with the water. From here, emergency locator transmitter (ELT) signals are emitted even within 14,000 feet to 4,000 meters.

This signal is a location detector for the Black Box. The signal in the Black Box will be sent every one second where it will last up to 30 days.

For this reason, when a plane crash occurs, the team tries as quickly as possible to find it. Because the Black Box becomes the key to knowing what really happened as the cause of the accident included.

Hopefully the parties involved in the search for the plane parts will soon find two complete Black Box parts. With the discovery of all parts of the Black Box Sriwijaya Air SJ-182 aircraft. We’re all going to find out how that plane crash happened. What caused Sriwijaya Air SJ-182 to crash into the Thousand Islands on Saturday, (1/9/2021).
