Poll: Would Long-Duration Cockpit Voice Recorders Improve Safety?

  1. Just having them won’t improve safety. But the insights on incidents that we can’t get now because they overwrite, should help training to improve safety.

  2. It seems obvious to me that CVR’s should be able to record the longest flight of which the aircraft is capable, from start to finish, if for no other reason than exemplified by the AAL flight taxiing across a runway on which DAL had already begun its takeoff. Intracockpit communications were lost on that flight as AAL continued to it’s European destination, a longer duration than the CVR could retain. Airliners that crash or are lost don’t always come to grief only due to events confined to the final two hours of their final flight, and surely having the entire flight on the CVR could sometimes be helpful in the investigation.
