Is YYZ-HKG A Trans Polar Route?

Sat Dec 13, 2003 8:11 am

I have seen 2 or 3 topics lately mentioning that AC flies HKG-YYZ nonstop, but makes a stop at YVR going the other way, because of prevailing winds. However, the Great Circle Mapper shows that the GC route passes fairly close to the North Pole. As the course runs almost North/South why would prevailing winds be a factor?

I don't think it is, I know the CO flight from New York to Hong Kong is.

I dont know why the winds would be a factor but Im sure there is some reason... Seems to me that the route would be over the north pole otherwise the route would be much longer

Cathay flies YYZ-YVR-HKG. No non-stop, and I believe the same goes for AC.

And, FYI, airlines don't always follow a "great circle" route. I've flown AA several times DFW-LGW and DFW-FRA, and due to winds they usually hug the east coast from the Chesapeake up to Nova Scotia before crossing the Atlantic; a great circle route would take them more over the Great Lakes area.
"Lose" is not spelled with two o's!!!!

Ssides,

I realize that airlines don't always fly a great circle route, but in this case - YYZ-HKG, there is such a huge difference in the distance between the GC route (6787 nm) and the YYZ-YVR-HKG route (7366 nm) that I wondered if there might be another reason for not flying the polar route. Not having overflight rights for China perhaps - which doesn't make sense as Hong Kong is part of China now.

It goes close to the pole.

AA61hvy, how did you chart that route above?

I dumped at the gybe mark in strong winds when I looked up at a Porter Q400 on finals. Can't stop spotting.

I hoped somebody would be able to answer my question, but I guess nobody from AC who might know the answer is reading the topics on this forum.

I've read in another forum, that the HKG-YYZ non stop is not a polar route. It follows a similar path as HKG-YVR but continuing to YYZ. Even though the polar route is shorter in distance, the winds allow the route via YVR to be flown in a faster time.

Well.. why don't we just wait and see. On March 24th (yes, still a ways away), I will be flying HKG-YYZ direct so i will let you know how the route is flown exactly.

That is interesting, but still doesn't answer my question, which is about YYZ-HKG. Surely the winds can't be more favorable via YVR in both directions, or can they? If they still need to refuel doing a polar route westbound, then Churchill, MB would be a good choice. It is only 20 nm longer than the YYZ-HKG Great Circle distance. YYQ has a 9,200' runway and has jet fuel.

Winds affect YYZ-HKG or JFK-HKG significantly which causes the payload problem. Therefore Refuelling is needed. For example, CX stops at YVR for refuelling because it's oen of the CX online port with full support.
