A black box with a two-hour memory was installed on the AZAL plane.

Azernews reports via Azertag that this was stated to Kazinform by Talgat Lastayev, Deputy Minister of Transport of Kazakhstan.

He said that usually two black boxes are installed in the tail of the aircraft and both have been found.

"They are currently being transported for decoding. This aircraft had black boxes installed that recorded the crew's work and the aircraft's technical parameters for two hours," the deputy minister said, noting that the full picture of the incident would become clear during the investigation.

According to him, all "black boxes" are divided into two types. "The first is the voice recorder or CVR (Cockpit Voice Recorder). It records everything that happens, all voice messages and audio conversations between crew members. From the very beginning of the flight, the black box automatically records all this information: how, when and what the crew speaks, how they react, and so on. The second black box is called the technical or FDR (Flight Data Recorder). It records the technical parameters of the aircraft: engine speed, oil pressure, hydraulic pressure, rudder angle and aeronautical data," said Deputy Talgat Lastayev.
