I have this question about United's new routes from SFO-SYD. I know for routes like that, airlines would most likely use the LR variants. For example, Delta and Air Canada. But United is using the 200ER variant. My question is, does the ER have capability and range for that flight? I would've never imagined the ER variant on a long haul over the pacific like that.

 

 

 

 

The 777-200ER's max range is about 7725nm (according to boeing.com). The great circle distance from SFO to SYD is only 6445nm. So appearently it is no problem for the ER. Otherwise if they would not be able to go with full payload to cover that distance, they would have to sacrifice some Pax seats or cargo.

Just found that article. I

No, it does not. They will fail and crash into the Pacific 

Sorry...what I'm trying to say is it probably is perfectly capable if they're using it. For an expert opinion, wait for someone else to reply

Hi, Trystan,

 

United (and before the merger Continental), has been flying the 200ER Newark to Hong Kong for quite awhile.  It's several hundred miles longer than SFO to Sydney.  They also fly Newark to Delhi, @ 150 nm shorter.

 

Here is Boeing's 777 range chart:

Interesting article nevertheless

SFO to Sydney shouldn't be a problem for the 200ER.

Thank you very much for all of the replies guys!

The pre-merger UA 777s and pre-merger CO 777s had different engine ratings, the CO birds had more range even through they were both -200ER. Apparently the UA 777s have gone through some sort of upgrade for their MTOW, according to some other boards I've read.

 

Regardless, UA has been flying this version of the 777 ORD-HKG, which is a longer route than SFO-SYD.

My impression is that United has been using the former Continental T7ERs, which have GE engines, for their longer routes, not the original United T7ERs with PW engines.  I believe you are right that the GEs have a somewhat higher thrust rating.  You can tell the former Continentals by their tail numbers, which are N followed by 5 numbers, while the older Uniteds are N###UA where #= a number. 

 

Interesting that United is upgrading, presumably, their PW T7ERs.

You are correct; many of the old CO 777s have been used for the longer routes. The 777s being used for SYD routes will be old UA birds, however, as they are three class versus CO's two class variant.

This is an automatic message.

One question I have is this:  If 777-200ERs can make these ultra-long haul routes, why do some airlines buy 200LRs?

Air New Zealand use the 200ER on CYVR and KSFO for quite some time.  CYVR NZAA    6330.6 nm  KSFO NZAA 5693.8 nm

 

Sydney to KSFO is 6575.6 nm  Sydney to Vancouver 6841.9 nm, so as above well within the capabilities of the 200ER
