If someone can show me one instance where monitoring or downloading CVR data after the fact would have stopped an accident, that would be helpful.
We need to differentiate between two entirely different concepts.
1. The use of ANY aircraft recording device in the use of discipline should NEVER be allowed. At no time should a CVR be used by management for discipline. Therefore proposal by this legislator is awful and should be stopped.
2. Adding CVR to the FOQA type mix, as proposed by NTSB. In this scenario, the CVR data would be DEIDENTIFIED, and ONLY the union gatekeepers would know the identity of the crew. My thought is the union would transcribe it, so the voices are not there for anyone else. An identified problem with an individual would be addressed by pro stan.
Further, due to the workload (which is why ATA is concerned with the idea), it would only be done on flights where the FDM indicated a problem.
Now, with THAT backdrop, to say that adding that information would not be of value is to totally misunderstand post incident/accident analysis (should add that most pilot unions opposed CVRs in the first place based on many of the arguments proffered in this thread, i.e., "pilots would literally shut the hell up and not say a word, hence killing their worth", and none of those concerns proved to be founded). Having reviewed literally dozens of accidents/incidents/events, I can think of MANY times where the CVR would have been helpful to sort out what happened and why. The only other way is to interview the crew, but that might or might not give you good data. Human memory is not very good, for one thing. If there is a problem of willful non-compliance, then that information should be available to the company to incorporate into general training, safety promotion, etc. Particularly if it is a widespread issue.
The union can have their pro stan folks talk to the individual crews either way, but if it is a wide trend, the fix is going to be in the AQP, safety promotion and similar.
