[–] don@lemmy.ca 1 point 1 year ago (1 child) More black boxes mean more money, something air line corporations really don’t like paying. permalink fedilink source parent hideshow 2 child comments replies: [–] squaresinger@lemmy.world 2 points 1 year ago What I mean is that black boxes are technically super easy today and shouldn't cost a lot of money. All you need is basically a microcontroller writing to an SSD in an armored, heat-shielded box. Should be cheaper than a single seat. I couldn't find up-to-date prices. The only thing I could find was that in 1993 a combined cockpit voice and data recoder that was made in a way that it would detach from the plane in case of ditching in water would cost ~$60k per piece. That was in a time way before shock resistant SSDs, so it was mechanically much more difficult to build that. Can't imagine that a modern airplane grade black box costs more than a couple thousand. When it comes to cars, all you need is a microcontroller logging to an SD card or EMMC. That costs maybe a few dollars. permalink fedilink source parent
