Going back to link 959 and subsequent discussions:
Now, I understand also why the BEA would like to have the whole scene with all pannels filmed as many things said all along are related to instruments and very hard to guess what it was exactly.
The desire to capture cockpit video has been around for a long time. Now that we have glass cockpits, the ability to capture these now exists as well. One point missed in discussing all of this is that it does not need to be captured in "real time," which would in fact require large amounts of memory. If there were two image streams, one of the cockpit, and one composite of all of the glass displays (direct content), these could be captured with quite high resolution, but only at a rate of one capture per second. Nothing will change so rapidly that 1PPS will miss much of significance, and with a modest (in today's terms) amount of memory, one or two hours (or perhaps even an entire flight) could be captured for future reference if needed. The technology now exists. It should be done.
Thoughts.
