Why is it called a black box when the two devices are orange-red? The black box is orange-red to make it easier to find. In English, “black box” means a closed system that cannot be influenced from outside. The inside lies in the dark and is isolated from the outside world.

Why do we speak of a black box when there are two devices?
The so-called black box comprises two recording devices, the flight data recorder (FDR) and the voice recorder (cockpit voice recorder, CVR). They record thousands of parameters. Both devices can be present individually in an aircraft or housed in a unit.

How are the boxes evaluated? The data is stored in a flash memory, a kind of USB stick. The evaluation of the two data carriers is subject to an internationally precisely defined procedure. This should prevent manipulation of the sensitive data as much as possible and guarantee data protection for the pilots. In civil aviation, the country in which an accident occurs or the wreckage of an aircraft is generally in charge of the evaluation. The local authority also decides which experts are called in.

  • Comment from Achim Frill (Afri)
    A professional can certainly answer that for me: Why is important voice and flight data not sent non-stop by radio to a safe place and stored there? The often unsuccessful search for these devices would be superfluous. Or am I missing something important?
