Boyd,
Anyone who is concerned about having every word uttered in the cockpit of a private aircraft being compulsorily tape recorded...
Just a touch melodramatic there old chap. Every aircraft I have operated with a CVR records just the past thirty minutes of cockpit voice and sounds. They all carry an erase button that may be depressed after landing to completely erase the tape (or chip in the more modern units). Not a ‘big brother’ device at all!
I understand in the Lear accident that claimed the life of Paines Stewart the CVR was useless as the occupants were deceased during the last thirty minutes, and such would probably have been the case in the B200 incident. But no doubt the CVR is an effective tool in accident investigation and therefore must have preventative capabilities.
