This Penny & Giles system is light and robust, and provides 30 minutes highquality all channels and 120 minutes of combined recording. In this installation the Multi Purpose Flight Recorder is configured as a cockpit voice recorder. This CVR simultaneously records four separate voice inputs. These inputs are taken from the following stations: pilot, co-pilot, third crew member and cockpit area microphone. The CVR will record 30 minutes high quality all channels and 120 minutes combined recording. The system performs this task using three essential components: the recorder unit, control unit and area microphone. In addition, an impact switch is installed for automatic shut-off of the recorder if it exceeds 3.
