Cockpit Voice Recording Module

flight recorder is an electronic recording device placed in an aircraft for the purpose of facilitating the investigation of aviation accidents and incidents. Flight recorders are also known by the name Black box—they are, in fact, painted bright orange in color to aid in their recovery after accidents.

There are two different flight recorder devices: the flight data recorder (FDR) preserves the recent history of the flight through the recording of dozens of parameters collected several times per second; the cockpit voice recorder (CVR) preserves the recent history of the sounds in the cockpit, including the conversation of the pilots. The two devices may be combined into a single unit. Together, the FDR and CVR objectively document the aircraft's flight history, which may assist in any later investigation.

This Module forms the central unit of the Flight Recorder, responsible for cockpit voice recording and communicating with Communication Module and IO Module in the Flight Recorder.
