I agree but I also wonder if there are good reasons more alarms aren’t used.

Far worse than the occasional silent failure are too many false alarms. The medical profession has this problem.

If you get too many alerts, people ignore them. There was a series of incidents where pilots were routinely pulling circuit breakers to silence takeoff config warnings going off while taxiing. Eventually a plane took off without flaps and a lot of people were killed.

Automation is very complex and the solutions aren’t always so straight forward. People forget there is a serious risk of adding an alarm causing more accidents.

Should there be an alarm here? Seems obvious there should be and there better be a damned good reason there isn’t.
