JAKARTA - TNI Commander Marshal Hadi Tjahjanto said that the black box signal of the Sriwijaya Air SJ-182 aircraft had been monitored by the joint search team.

When the black box signal has been caught by radar, Hadi hopes that the two black boxes of the plane that crashed in the waters of the Thousand Islands can be found soon.

"Evidently, the two signals issued by the black box can continue to be monitored and can now be marked. Hopefully, in the not too distant future, they can be picked up," said Hadi at the JICT2 Command Post, Tanjung Priok, Sunday, January 10.

The black box installed on an airplane is divided into two parts, namely the Flight Data Recorder (FDR) and the Cockpit Voice Recorder (CVR). FDR is responsible for storing flight parameters for 25 hours before being overwritten with a new record. This information includes speed, altitude, time, and direction of the aircraft.

Meanwhile, CVR keeps conversations between the pilot and his crew or the control tower. The recording period is two hours, after which it will continue to re-record itself and overwrite the previous data.

"Until now, we continue to strive to obtain black boxes, so that they can become materials for the National Transportation Safety Committee to find out the cause of the accident," explained Hadi.

The Sriwijaya Air SJ 182 plane crashed around Male Island and Lancang Island, Thousand Islands, or 11 nautical miles from Soekarno-Hatta International Airport, Tangerang-Banten.

The Boeing 737-500 PK-CLC registered aircraft crashed when it was about to climb to an altitude of 13,000 feet above sea level.

Before take off, the SJ 182 plane also delayed its departure for 30 minutes due to rainy weather.

The NTSC is currently working with the Meteorology, Climatology and Geophysics Agency (BMKG) to collect weather-related data.

The Boeing 737-500 has a crew of six active crew. The details of the passengers on flight SJ-182 are 40 adults, seven children, three babies and our six crew members as passengers.
