Because it's simply not possible to make black boxes redundant.
You can fly into a storm or into a canyon where radio/satellite uplinks won't work. Hence you need to store the data on sturdy local storage aka a black box.
As much as people love to think that technology can completely tame mother nature, it can't. It's still a brutal place, with nasty conditions. While the uplink data is great, you still need backups (Higher resolution is a nice bonus too)
- ajross 17y agoA better way to explain it would be to point out that the remote telemetry and the black boxes are already examples of redundant design. The black box has fewer failure modes recording data, but requires recovery. The telemetry is more easily disrupted, but can get data out even in the face of a total loss of the aircraft. Redundancy doesn't always mean the same thing as simple duplication.
