Not sure why you're getting downvoted for this comment, but I agree with what you're trying to say regarding storage. Granted, of course there are some survivability and hardening considerations to take into account for this application vs. your iphone, but at it's core we're talking something not too dissimilar in concept. For reference, this is the link to one of these products: http://www.uasc.com/products/cvfdr.aspx http://www.uasc.com/products/cvfdr.aspx It clearly states that the data for modern CVRs are held in flash storage. For something that costs thousands of dollars, and is absolutely critical to after action flight accident discovery, there's no excuse not to capture the voice data from every flight in full given the current prices of flash storage.

Not sure why you're getting downvoted for this comment Probably because I said I had an iPhone :). Either that or the people downvoting it thought I was suggesting that we plug an iPhone into the cockpit and all will be well. I was simply saying that many of these problems have been solved for use in far less important applications, so it should not be that big of a stretch to get them into commercial aircraft. The suggestion that it might be possible in 2014 to install additional memory into a CVR is apparently such a technological leap that it is worth 5 downvotes :). I cannot wait for the day when it might not sound so crazy.

  No, it's because you're not considering properly the problem at hand. You're comparing apples and oranges by comparing consumer hardware capabilities and the capabilities able to be achieved for a hardened service environment solution. It's the same reason why we don't just go and install a new quad core x86 on rockets for their guidance.

    So you are saying that there is a hard technological limit of 2 hours on a CVR because it must be in a hardened container. Got it.

      No, thanks for taking my words out of context. I'm saying that there's a whole litany of processes and requirements alongside storage capacity that necessitate limitations. In the case of storage, it will be that certian memory chips, etc. have not been through the process of hardening them. Just like how the latest core processor could run all of the equations required to guide a rocket to orbit, but it sure as hell isn't done on one of them because a number of other features would be neglected. Is it possible to get more than 2 hours of memory in a CVR? Sure. Why hasn't it been done? Due to a variety of other considerations on hand.

The initial downvotes were because the comment was much shorter and less informative when it was originally posted.
