Why the fuck would they have only hours of recording? Even my cheap voice recorder can go for hundreds of hours
Flight recorders have a very long history with modern ones being engineered in the 1960s. They used film and magnetic tape loops, having very limited capacity. That's where we get 2 hours from. Early ones only ran for 30 minutes, so 2 hours is pretty good in comparison.
It's time to upgrade the regulations to match our current technology instead of 1990s limitations.
Modern ones are solid state and the owner can choose how long they want to record for. Most ETOPS aircraft will record for much longer than 2 hours. I believe my airline records for 25 hours, even though our aircraft are not based in Europe.
Absolutely. My comment is about why a regulation would be 2 hours when today we can get more capable, air rated parts. US regulation is lagging behind, but it was based on what was within reach 20+ years ago. Heck, I bet most craft would eventually become 25 hours voice recording as older standard recorders become no longer available.
