Yep, no brainer. Battery backup and longer recording.
I believe that Europe has mandated CVRs record for 24 hours. That may be due to a pattern of flight crews forgetting to turn off the recorder after an incident. (It’s easy to forget, there’s a lot going on after an incident.)
But I was surprised to hear that there is no battery backup for the CVR/FDR after the recent Jeju crash.
