How much is it round trip on the SIN-EWR flight?
= 8,285 nm
= 8,646 nm
Although SIN-EWR is hypothetically less affected by winds because it is more of a north-south route, will the 772LR be able to do SYD-EWR?
, but it would come close to the limits of the aircraft. I would estimate a 400nm wind penalty and another 400 nm for reserve fuel, which puts the trip distance at 9,400 nm.
9,400 nm happens to be the point at which the 772LR can carry 300 passengers and bags the furthest, with no other cargo. It would probably be more ecomonical to reduce passenger capacity a little (~260-ish) and in return have the option to carry revenue cargo or lower the probablity of an emergency fuel stop. Also, removing a seat row or two adds pitch, which is a plus on a 18+ hour flight.
For 772LR performance data, see page 4
Or I guess the better question is if it can do EWR-SYD
Again it could, but JFK-SYD would be a much more logical routing for an airline like QF. For QF, they can fly to their U.S. domestic codeshare partner (AA) who has lots of connecting flights via JFK. AA has very little presence at EWR.
If CO or SQ aquired 772LR, SYD-EWR would be a more appropriate routing.
