Found the second black box of the plane of EgyptAir

The Flight Data Recorder (FDR), which records every second all the technical parameters of the flight, such as speed, altitude and direction of the unit, "has been found in several pieces," but research teams were able to retrieve "the most important part, which contains the memory of the device," adds the statement.

On Thursday, was found the first "black box" of the aircraft, the Cockpit Voice Recorder (CVR), which records all conversations in the cockpit, sounds and listen to ads on the site.

According to the rules in force, a commercial airliner has two "black boxes": FDR (Flight Data Recorder), or tape recorder which records all flight data, and TRC.

The se recorders, introduced in aviation from the early 1960, are inside of metal reinforced boxes, designed to withstand violent shocks, heavy fire and long immersion in deep waters.
