Why is this system not fully automatic?
If the FADEC has full authority over the engine, why doesn't the environmental control system have full authority over the cabin pressure?
Surely Mr. Boeing has some kind of a warning: "Excuse me, you're climbing without cabin pressure, have you forgotten something?"
Surely there is a serious warning on the flight deck long before the rubber jungle?
Surely the cabin staff are alert to this? Can't they prod the guys up the pointy end?
We have had pressurisation failures for decades: why has this not been dealt with?
What am I missing here?
