just thinking …
If you record while airborne and store while airborne, then you could start to transfer that data from a position that puts you in reach of the ground station.
From the ground station you can then distribute it over higher volume networks.
That would make it possible to have data for analysis before the plane arrives at the gate.
So precise language is needed here … is it continuous any altitude air to ground streaming… or batch/burst when in reach…
the functionality is similar but the performance quite different… bandwidth and range …
the crash area is quite remote and rough by the way and even the SAR had Comms issues …
so even a working batch system would have had coverage issues,
