United to Launch U.S.-India (Direct) Flights
Read the article here - http://biz.yahoo.com/apf/010814/united_india.html
Its a 7500 mile trip and takes 14/15 hours on the 744.
Would the route fly up North from VIDP over the pole and then due south towards KORD or would there be some other route, e.g., overNorthern Europe then the usual NATS way?
Any knowledgable sources?

Looking at my globe and measuring with a piece of string, it looks like the route will be over Greenland, north of Norway, past Moscow and down over Afganistan- nothing unusual. It looks approximately similar or slightly less than BA's LHR-Singapore route, the effective max range for a 400 without restricting payload much and allowing for a headwind on the return sector.

not sure as i don't have the charts in front of me but, would that route not fly directly through the compass unreliable zone? is this not a factor with gps/sat nav/acars etc ? just asking as i never get to do that kind'a stuff ?

GPS works fine up there! If you forget to flip the Heading Reference switch from Magnetic to True, the airplane (744) will do it for you!
Last time I did it, ACARS and HF worked fine!

If you're in HF range (and if you're in the solar system, you are) then it's technically possible to get HF based data link. If you have the right boxes in the ship, you'll get the messages on the little ACARS/AFIS whatever screen you usually get such messages on. Knowwhatahmean?

OK, and after sitting on an airplane 15 hours you will not know where you've been and it wouldn't matter where you get off, because you wouldn't be functional for the next two days anyway.

InitRef:
Last I checked (bored over the Pacific several months ago), the 744 with GE CF6-80C2B5F engines can take off at max GTOW (398.9 Tonnes) at 40 deg C at any airport normally served by the 744 (I believe Quito was an exception, but it never gets to 40 deg there). Other engines may impose restrictions.

TVA164 and Flight plan man,
Have a look at http://gc.kls2.com it gives great circle route depictions and distances.
(Intrigueing site). ORD-DEL is 6516nm and tracks over the east coast of Hudsons Bay, across Northern Baffin Island, Northern Greenland and just east of Novaya Zemlaya (sp) and to DEL.

Actually, thanks go to Innuendo and LurkR for the links.
Innuendo you are spot on here. It defaults to statute miles and if you select nautical miles, the number is about 6503 as you reported earlier. Also, mind you it will get longer once the route is recalculated using airways - as such it seems the route would take the aircraft through a lot of "restricted" airspace so deviations are bound to be factored in. An example would be while overflying the Hindukush region - expect a lot of zig-zag headings there. Russia might prove similarly long. Any more ideas here?
A follow on question - without poring through endless charts, is there anyway to map the route using airways? Any pilots or flight ops personnel familiar with the regions the flight path would take?
Cheers.

Canada 3000 are apparently planning YYZ and YVR to Delhi with an A-340.
Great circle from yvr is 6040nm, yyz 6309nm.
YVR to HKG is 5550 give or take and a full load of 284 pax meant max t/o weight of 275k using Macao as an alternate so I would guess that full payload may not be available. The Great Circle site gives EWR to HKG as around 7000 nm which Continental and United were/are doing so obviously the DEL route is feasable. Interesting that you can do ORD and YYZ using 180 mins etops according to the chart. I have no experience of engine out terrain clearance routings in the area of the Himalayas and I wonder if this would impact on the DEL outbound routings? Some body here must know.

I think this route is pretty interesting because of these:-
1. It flies almost right over the north pole (heading would change from the 350s to 010s as you see it (probably, I'm only guesstimating)
2. It slices down the middle of Russia direct towards the Himalayan range, again, interesting terrain...
Any more?
