The US govt. federal agency Federal Aviation Administration (FAA) is responsible for the safety of civil aviation and its regulations require civilian aircraft to have a CVR (cockpit voice recorder) and a DFDR (digital flight data recorder). Most countries use FAA regulations as the basis for their regulations.

The CVR typically keeps a record of the last 30 min of cockpit conversation.

The DFDR keeps a digital record of 80 or so separate flight parameters every second of the flight. This DFDR is housed in a crash-resistant housing, typically an orange-and-black striped box. This is popularly called the \"black box.\"

With the data from an intact functioning DFDR, a computer can display the complete flight as a virtual simulation. Very useful for investigating faults and accidents.

The Black Box Flight Recorder (which is actually orange in colour) was invented in 1953 by an Australian who considered that an onboard flight recorder in the cockpit of the aircraft would be a way of solving unexplained air accidents. The idea was not accepted internationally until 1957 and then not until 1962 did it become mandatory for all Aircraft to have these recorders installed in all passenger aircraft. These machines record all voices and flight data for analysis after a crash and they transmit signals for a period of time to aid their recovery. the box is made from 3 layers to withstand damage from impact and heat.

Intrestingly it is orange in colour. There are two devices. One is flight data record and another is cockpit voice record. Both of these collectively called Black box. It is so made as to keep all data safe even after fire , water and presure after any accident. Black box emits some signal also up to 30 days after accident so as to search it.

In aviation, the term \"black box\" refers to both flight recorders on commercial and other aircraft. The flight data recorder is responsible for recording flight parameters and the cockpit voice recorder is responsible for recording all communications in the cockpit of an aircraft in flight.
