London-Perth Non Stop Virgin B787

Re the Times today: Assuming similar routing and speed, what is the expected flight time saved by omitting the Singapore intermediate stop?

[Maude Charlee]

Article said something like 17 hours.

Looks like they'll no longer be crowing about 4 engines being better than 2 anymore then.

I saw the 17 hours and that's what made me wonder. Having used Singapore Airlines a few times, the eastbound flight times are roughly 12.5 hrs and 5.5 resp. All a bit rough and ready, but surely Changi holds, IAP, taxi , park, open doors plus all the take-off stuff, climb to cruise etc to be worth a bit more than an hour saving?

There are a total of 6 starter/generators on the 787. Four 250KVA units are engine driven and the APU turns two 225KVA units. There is a RAT, but it is for center system hydraulics only.

The FAA made new rule changes regarding ETOPS in January of this year. I will have to check to see if out of the box approval is part of the new rules. I do know that the 787 will have 180min ETOPS equipment and systems in all base models.

Just out of interest Emirates 777-300ER are, so I believe, running 207 mins ETOPS... Don't know how much time those GE's had before that was granted:confused:

Didn't the first B777, the one delivered to United come with 180min ETOPS??
