CVR Erase Function

In view of recent developments, the Federation believes that it is necessary to restate its position that a Cockpit Voice Recorder (CVR) erase function, accessible by the flight crew, should continue to be installed in the flight deck of all commercial transport aircraft. There have been numerous examples of CVR recordings being used for purposes other than accident or serious incident investigation, including publication in the media (e.g. American Airlines flight 965 and GOL flight 1907) and listening to flight crew conversations by airline staff for internal use.
