Apparently, the Dali lost all power. Anti collision kind of needs power to work, so having it would not matter regardless
As an electrical engineer I will say there are giant thick sections of code for backup power regarding life safety systems. Generally a backup generator will keep running even if on fire and breaking just to keep power on... backup batteries on even more sensitive equipment provides even more redundancy. Power failure leading to a disaster is a engineering failure.
Maybe they were inspired by Boeing to skip the QA checkups on some of those systems 😉
Yep. "Business" doesn't see profit in redundant systems.
