Wonder why the CVR didn't provide the factual answer to whether the RA was a "descend descend" or "reduce rate of descent" aural?
If they were approaching FL220, they'd have been about 70 miles to run, and 20 mins or so from block-in. For a 30 min CVR record, I guess it may have just been overwritten by the time they shutdown.
My company recommends (mandates?) the CB manually be tripped to preserve the CVR record in the event of an incident.
Any other companies recommend this?
