How does LATAM fly the 787 between AKL and SCL?

Fri Jan 11, 2019 10:37 pm

Don't ETOPS regulations require a quad-jet on this route? Is there a island where they can land a 787 in an emergency?

B787 will be certified for 330 minutes. (5 1/2hours).
Not been a pilot, my calculation give me that plane will be always between 51/2 hours of Auckland or Santiago, been distance between them
Around 11:00 (direct flight)
As I understand, mayor concern is Jet lag. But, with higher humidity and cabin pressure, expectation are...

The 787 has been certified for ETOPS-330 since 2014 and using Great Circle Mapper it looks like they can fly a direct routing. The FAA has reduced ETOPS for the Trent 1000 family in certain situations, but those might not reply to a Chilean-registered airframe or if they do, LATAM might be using frames powered by RR engines not under the FAA restrictions.

Did the Lan Chile 767-200ERs have enough range to fly from SCL to AKL?

Perhaps if they were empty. :)

I think the 767-200ER is limited to ETOPS-180/207 and that means it would need to take a far more northerly track to stay within range of alternates and that would significantly increase the total flight time / distance to the point it would certainly impact available payload due to the need to load more fuel.

Are We talking about a B767-200 or B787?

Both.

The 767-200ER and 787-9 have the range to make the trip with their design payloads flying a direct path, however ETOPS routing considerations allow the 787 to fly direct under ETOPS-330 while requiring the 767 to fly farther north as there are no available alternates within ETOPS-180/207(/240) minutes to allow a direct path.

They also fly the 789 between SCL and MEL, and that’s even longer.
