In black box location search is supported by sonar scan and multibeam echosounder (MBES). After that, the team conducted an analysis related to the location point of the Black Box and then given to the diver on duty.

Black Box Flight Data Recorder Sriwijaya Air SJ-182 found
On Tuesday, (12/01/2021) a search was resumed focusing on the Plane’s Black Box which is an important part in addition to the victims and plane debris.
Previous Position Of Black Box Sriwijaya Air SJ–182 Found after KRI Rigel caught two signals from the black box on Sunday (10/1/2021). At about 16.20 WIB, finally the black box of Sriwijaya Air SJ-182 aircraft was successfully found by a joint SEARCH team after three days of searching and narrowing the priority location point in the search.
Based on a live broadcast from Breaking News KompasTV, the Black Box or black box was found by the Navy’s Kopaskal Armada 1 team.
The team explained that the Black Box position is between Laki and Lancang Islands, Kepulauan Seribu, Jakarta at a depth of about 17-20 meters.
The plane’s Black Box was put in a white container box with a blue lid measuring 40×30 cm. Then lifted to the sea rider ship owned by Kopaskal to be taken to JICT 2 Tanjung Priok, North Jakarta. Furthermore, the Black Box will be submitted to the National Transportation Safety Committee (KNKT) team for further research.
Based on a statement from the COMMANDER of the TNI named Marshal Hadi Tjahjanti, the Black Box found only in the form of FDR (Flight Data Recorder) section containing flight data records.
For the other part, CVR (Cockpit Voice Recorder) is still in the search stage. He believes that cvr location is not far from where FDR was found.
KNKT team takes 2 to 5 days to download data
According to the Chairman of the National Committee for Transportation Safety (KNKT). To download data from this FDR, the KNKT team takes at least 2 to 5 days.
The team also hopes that another part of the CVR containing recordings of conversations in the cockpit will be found soon. Thus, the cause of the Sriwijaya Air SJ-182 plane crash will soon be revealed.
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).
