Im going to be doing a flight on FS from O'Hare to LHR (nightflight), and I was wondering what kind of route do the real United Airlines aircraft take.
I understand the 777 must be within 340 miles of land, and have reserve fuel, but what kind of flight routing ensures they do this, and how is the quickest way.
Also is it a good idea to have the course follow round Canada, and drop south over Scotland, or to have it as a normal Transatlantic routing.
Finally, what times would I be looking at, Im aiming for a Dawn landing at LHR, so what time would be best departing from Chicago.

Closest I can get is a flight I took from ORD-MAN (relatively close to LHR). The British Midland A330 I flew probably took a similar route. I tracked the flight on the IFE screen. The plane departed ORD at 6:30PM CST and headed west across Lake Michigan and over Ontario, Canada heading NW. We followed close to the St. Lawrence river and NW to Newfoudland and the Gulf of Labrador. After a little over three hours of flying we crossed the Gulf of Labrador into the Northern Atlantic south of Greenland and Iceland. We entered the European continent at sunrise over Ireland after approximately six hours of flying and made a 7:15 landing at Manchester, UK. I am assuming the UA 777 would follow a similar route and get to LHR not long after.
In general, many flights seem to depart ORD to Europe about 5:00 in the afternoon and arrive in the morning.
Best wishes with the simulated flight.

I took American 86 (ORD - LHR) Sep 5. Departure was 5:10 PM and we arrived about 5:45 AM, circled 20 minutes (no LHR landings till after 6 AM) and still arrived 50 minutes early! Scheduled arrival was 6:55 AM
Don't remember the exact flight path, but was close to what Corsair2 listed.

Not quite sure what you were referring to when you said 'normal transatlantic routing' instead of going out over Canada - the 'great circle' route, which is the shortest distance between 2 points on Earth, takes this path:
Obviously the actual route flown will vary from this to take advantage of favourable winds, etc. but virtually all north atlantic flights go out over the north-east of Canada, through Newfoundland, and transatlantic from there.
