If this 777 is ETOPS 180 certified, it means it has met certain standards that allows it to fly up to 180 minutes from a suitable landing site. Things like necessary equipment, maintenance and MEL restrictions, cargo smoke detection and suppression standards, pilot and airline licensing requirements, etc.
“I know that” cuing the eye rolls.
What is DOESN’T mean, is that the aircraft is capable of suppressing, solving, fixing, etc. EVERY possible emergency for 180 minutes. If an on board emergency presented itself, the pilots don’t just lean back, relaxing saying ...... ahhh, there’s no hurry, we have 180 minutes. Think say, cabin fire, medical emergency, fumes/smoke, uncontrollable engine fire, etc.
That is why the actual pilots on here are curious about what was actually going on in the cockpit of that airplane. But ..... the CVR may never be public, the FAA may be satisfied, Delta may be happy with the performance of the pilots and no further action will be taken. So relax kids, there’s a very good chance you’ll never know!
People understand just fine.
The point is so do the pilots. They know that if it’s a simple compressor stall, they have plenty of time to tool around in a hold at 8000, dumping fuel, communicating with ATC, planning approach. That situation is not a get it down yesterday situation that allows them to violate public safety rules.
So everyone wants to know what the event was that would make 4 experienced pilots act in such a manner, not communicating with ATC and dumping fuel at a low altitude.
As others have pointed out, they could have dumped over the valley above 6000 net altitude (the northern areas of calabasas all being well under 1500ft elevation and all other points being lower).
