AC's 777L and ETOPS
Looking at the maps, it would seem they would need at least ETOPS 180 minutes to do YVR-SYD without a big detour.
Anyone around knows what ETOPS rule they go by?
(Even 180 minutes, i.e. three hours to the closest airport is marginally scary...)

also, keep in mind the rules have nothing to do with h2O. i am sure others can find "ETOPS operation has no direct correlation to water, nor distance over water. It refers strictly to single-engine flight times between suitable diversion airfields; regardless as to whether such fields are separated by water, deserts, polar expanses, recurrent (i.e. night-time) airport closures, etc."

Ac 777 ETOPS YVR - SYD
As far as I know it's 180...a bit scary, but there's lots of alternate airports along the way - Kiribati, Tahiti, Samoa, Cooks, New Cal. Probably not much different than 1/2 way on YVR - HNL, when you are approx 150 minutes from any alternate.

ETOPS is a combination of aircraft and engine type certification, additional equipment (ie: fire suppression), training and maintenance organization certification, and certain maintenance procedures and cross-checks.
For instance, if two engines need to be serviced on an ETOPS plane, two seperate crews must be used. The same crew is not allowed to change out both engines, for fear that they'll duplicate a critical mistake (ie: just like the bozos that installed the wrong parts on that Transat A330).
The Minimum Equipment List is also much more restrictive for ETOPS operation. Many 'deferrable' items under a non-ETOPS regime simply are not at all deferrable under ETOPS.

Flew earlier in the week YYZ_SYD. Spoke to one of the relief pilots for a bit and was asking him about the routing and ETOPS. He told me that right now its a 180min rule, although he said that there is talk of extending the ETOPS time.
