Is it arrogant to wish to survive a common civilian airplane flight?
And any change involving tech/gear are preferable to changes involving procedure (either more of it, or changes to it).
Extending the recording length on voice recorders to a higher number seems pretty straightforward (and already done elsewhere).
Yes, voice recorders should last long enough to capture everything that happens on a flight. But at the same time pilots should have protections to make them feel safe from retaliation.
Aviation safety is an incredible achievement that we as technologists should learn from. It’s not fertile ground for self-proclaimed “engineers” to piss their pet theories upon.
The aviation industry, and its monopolies, have to stop being treated as sacred cows and be subjected to thorough - consequent - scrutiny and accountability at all stages of the aircraft lifecycle. It certainly hasn't been the case with the 737 MAX - the system, as is, clearly failed the almost 400 people that already died. And if the MBA-types continue to have their way, the deaths won't stop there.
Finally, I'm not going to engage in insults, they only qualify yourself.
