VS901 NRT-LHR Northerly Route Today

Sun Oct 23, 2011 11:11 am

Hi all

Just noticed VS901 NRT-LHR is taking a very northerly route today - just coasted in southbound near Murmansk! Usually they take a much more southerly route, anyone know the reason for this? Congestion or weather maybe?

Cheers
Next flight: Feb 2012 - BHX-CPH-BHX - SK MD87 / CRJ900

It really isnt that unusual. Have seen NRT-LHR flights going that far north before.

I see ANA, JAL, BA and VS go that far north plenty of times. Quite a few times they travel down the Norwegian Coast (so even further north).

If you see on your own link, CAL069 is coming in from an even more Northerly route, and that is from TPE!!!!

From what I have heard, routing between Far east and Europe is a balancing act. Airlines would like to fly on the northern route for shorter great circle distance as well as for lesser headwinds. But Russian air navigation fees for that route is very expensive. So the daily route planners weigh the fuel cost of the southern route versus the extra navigation fees when determining the optimum route. But other factors such as weather and air space closures will come into equation as well.

If I'm not mistaken, this flight isn't allowed to overfly China. It usually takes a more southerly route over India and the Middle East, obviously favourable winds in the North (or more likely, unfavourable headwinds winds in the South) have led them taking the Northerly route around China.

Forgive my ignorance, but why is this? Does the PRC forbid it or is the cost too high?

An aircraft flying the shortest (great circle) route between LHR and NRT directly overflies MMN. So if everything else is equal it will be the preferred routing. The map here illustrates this:

The airways over China and Russia jog around quite a lot so a GC track distance is likely less than the airways distance.

I don't want to go too much off the topic but didn't the BA flight BA38 (PEK - LHR); the Boeing 777 that crashed in LHR fly an unusual more northerly route which resulted in the fuel freezing more.

I flew NRT-LHR last month on BA on an even more northerly routing - passing over the north of Novaya Zemlya and crossing over Norway around Hammerfest. I'm led to believe that this is quite common.

grimey,

That's not even that high.

You want high and constant costs!?

Try the North American and Asian carriers flying transpolar from Canadian airspace to Russian airspace to the Middle East/South Asia and mostly East Asia.

JFK/EWR-PEK/PVG/HKG crossing more than 80*N EVERY DAY!

Essentially the Americans, Canadians, Russian, Japanese, Chinese and Europeans figured out that flying higher saves more fuel but the airspace cost is $$$ over the Russian airspace (they make profit on this $$$) but I hear it may be reduced due to recent trans-polar meetings with all the parties and system upgrades on the Russian side (Specifically Nov. 17 RVSM in Russia & Central Asia).

Once RVSM is implemented I believe there will be more efficient routing from East/South Asia to Europe via Russia/Central Asia.

Transpolar JFK-HKG, circa trans-polar NRT-LHR...

The 777 does it every-day and is built for it.
