A350 seeks 420 minute ETOPS
The 240 minute rule for Extended Range Operations is for cargo fire suppression reasons. It has nothing to do with the engines. Category D holds meet this requirement. I flew the polar routes for many years using this rule and 240 minutes is enough to cover the entire northern North polar region so I wonder why they would need to have longer. Maybe for the South polar routes?
It is was indeed a requirement that you must demonstrate that you can recover the passengers in the event of a diversion within 24 hours if you fly up there.

As ever, life goes round in a big cycle...
If I recall correctly, the original term for twins was simply EROPS (Extended Range Operations) before it became ETOPS. Think we're just going back to the original name!!
As for being 420 minutes?? That must be for some trans-Pacific sectors, but there can't be many of those not covered by the existing regs..

EROPS - Engines Run Or Passengers Swim, which was eventually changed to ETOPS - Engines Turn Or Passengers Swim
.IIRC, 180 minutes could get you anywhere in the world, but the routing might not be optimum (mainland US to Hawaii being the tent pole route). After that, further increases simply allowed for optimized routing and/or certain alternates being unavailable.
