Thanks, looks like that’s a receiver unit that receives the data vessels send out via their transponder.
I know I’m going on about this but what system is being used to generate the data behind some reports that have appeared in the press is important.
I suspect when most folks think of the “black box” in the context of accidents they are imaging the sort of device many aircraft and many I gather some boats/ships carry that would have to be physically retrieved (in this case from the sea bed) in order for the data to be read from physical memory.
I’m not sure if a recorder has been recovered from this wreck, obviously don’t need to know, but do I know that in most jurisdictions and circumstances data from that sort of device is usually regarded as privileged at least in the early days of an investigation.
AIS is not the same thing at all, it may not provide as much detailed data to as an actual recorder, and most importantly it looks like the data is accessible to the whole world simply by going on to the internet and playing back whatever is held on a server…and the danger with that is that the data may get misinterpreted by keen amateurs and inaccurate stories start getting into the media.
If you want an example of how this can go wrong there was absolute crap talked initially and then repeated in the MSM about the Singapore airlines turbulence incident earlier this year because info on Flightradar (similar system in some ways to AIS) was miss interpreted by some and the MSM ran lurid headlines having not done a credibility check. It turned out the actual onboard data recorders revealed a different story
To cut to the chase, because I need coffee - I’d still be very wary of some reports that use AIS and “black box” in pretty much the same sentence…
