Extension of Cockpit Voice Recorder (CVR) Duration

Apr 21, 2015


Some recent reports of accident investigations have included recommendations that the cockpit voice recorder (CVR) recording duration should be extended. This was due to the fact that, following the accident or serious incident, CVR data had been overwritten and relevant information was not available to the investigation. In response to these recommendations, the industry has stated its capability to produce recorders of 25 hours duration.

This paper provides IFALPA's position on extension of CVR duration.
