Perhaps a silly question but why do we need to collect the actual, physical black box from the plane? Why can’t planes use satellite signal to periodically upload a few seconds of cockpit recording or even just flight data? Is it as simple as the files would be too large?
- fisherjeff 6y agoNo, I think it’s more an issue of reliability
- fighterpilot 6y agoDoes that matter if we're only going to use it in a situation like this? Some low reliability redundancy would still be nice
- moftz 6y agoThat's a lot of data to transmit via satellite and satellite bandwidth is expensive. Most planes don't crash into the middle of the ocean with all of the transponders turned off so it's an expensive solution for a very rare problem. Satellite-based ADS-B seems to be the future going forward. Everyone can see a plane out in the middle of the ocean and can immediately know where to look if it happens to go down.
- bionade24 6y agoI guess this was a bandwith problem when most of today's commercial air planes were designed and later on no one considered it. Probably will come sooner or later.
