The "real issue" is that CVR and FDRs are very complicated and specially built devices. They record detailed data and must protect it against ANY danger. Massive fires, being stuck at the bottom of the ocean, a plane slamming into the ground at a 90-degree angle, etc.
They must allow data to be recovered in as many cases as possible, prioritizing that over raw data storage amount or convenience.
- thih9 3y agoIt's not really about storage amount or convenience if the data is lost. That's no different than not surviving a fire. The "it took longer than 2h to retrieve the voice recorder" seems one of the dangers then. And at least just as likely as many others, e.g. it's easy to imagine this happening together with "being stuck in a remote place".
- Night_Thastus 3y agoIt is not about how long it took. It's because the pilots forgot to pull the circuit breaker. In most crashes, both recorders lose power so it's not a problem. In cases like this and the plane is fine, the pilots need to pull the breakers. Recorders have been found months after accidents and still retain all data.
