I don’t deny that it’s an important safety system. I’m curious, though, if they’re treated like safety critical systems in design or if emergency training covers how to act if the PA is down.

I’ve got to believe it’s safety critical.

I'd assume it's important to safety, but they have slightly less effective backups like yelling. I think the backup systems on aircraft are often things you'd rather not need to use.

I was thinking about yelling. I wonder if yelling on the larger planes is even viable. Especially in an emergency.

I suppose that would be a good hack to get the pilots to unlock the cockpit door.

There's usually a megaphone in the front.

Agreed, safety critical, used in emergencies and non-emergencies for safety procedures.
