NSEU:
Thank you for your reply.
All of the data from all of the sources you mention must be consolidated around hubs or maybe a central processor. I'm suggesting the recorders might be better located as physically close to those locations as possible.
I assume, but don't know, that the recorders are located at the ends of long cables back in the tail because back in the days when they were mechanical, it was assumed that location would suffer the least damage in a crash.
Now that they are solid state, the probability of damage to the memory is rapidly diminishing. The preservation problem is almost solved, so it might be time to focus on data input integrity.
