Absolutely the point, because none of what you propose is easy, let alone trivial... As you would know if you came close to civil aerospace development, certification or change management. You also ignore that it is more a policy than a technical problem, Europe has 25 hours and not 2 like the US. No idea how easy it is to retrofit the 25 hours into US certified aircraft with 2 hour recording, which might pose another problem. Bit hey, use your NASA credentials, apply to YC or any other VC, and launch your "trivial" tech solution.
