Ohare-Heathrow Flight Question

Tue Sep 30, 2003 7:36 pm

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.

Thank You
Its not the fall that kills u, its the sudden stop at the end..

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.

I've got a real flightplan for the reverse trip sitting in front of me...let me start typing.


UAL 949
EGLL-KORD

WOD/NB
CPT
RCA
STU
BAKUR
DEVOL
BABAN
KORIB
5520 (55 NORTH 20 WEST)
5430
5240
5150
CYMON
FIR
MIILS
FIR
YMW
FIR
TVC
POD
PMM
PAPPI
KORD

So that's the London departure procedure and the Chicago arrival route. You'd obviously want to fly the opposite there, the ORD departure and the LHR arrival.

Now, I don't quite understand all the rest of the ETOPS part of this flight plan, but I'll type it anyway so that maybe someone like Rick767 can explain it all a little better.

ETOPS PET1: SNN-KEF (EINN-BIKF) 02:17 N54 32.6 W025 38.4
SUITABLE ALTNS: SNN 0606NM KEF 0576NM

ETOPS PET2: KEF-YQX (BIKF-CYQX) 03:04 N53 03.0 W035 23.1
SUITABLE ALTNS: KEF 0768NM YQX 0765NM

Try this Planespotterx, this is todays BMA706. FL370, TAS of 471. Planned departure 23:30 (UK time i think), and planned arrival 06:07.

KORD..ELX..YXU.J586.YCF.J588.YMX.J553.ML..VALIE.NATX.SCROD.NATX.NIBOG.NATX.NURSI.UN551.BEL.UB3.IOM.MIRSI1C.EGCC/0637

NATX is STEAM OYSTR 55/50 56/40 56/30 55/20 KORIB BABAN
EAST LVLS 320 330 340 350 360 370 380 390 400
WEST LVLS NIL
EUR RTS WEST NIL

So, to get from IOM to EGLL, continue on the UB3 to HON, then a BNN1B STAR.

So, the fp is: KORD ELX YXU J586 YCF J588 YMX J553 ML VALIE STEAM OYSTR 55/50 56/40 56/30 55/20 KORIB BABAN NURSI UN551 BEL UB3 HON EGLL

Any questions, let me know!

Uh....

The plane departed ORD at 6:30PM CST and headed west across Lake Michigan and over Ontario, Canada heading NW.

Departed ORD and headed west over the lake?

I don't think that is possible because the lake is EAST of ohare.

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:

http://gc.kls2.com/cgi-bin/gc?PATH=ORD-LHR&RANGE=&PATH-COLOR=&PATH-UNITS=mi&SPEED-GROUND=&SPEED-UNITS=kts&RANGE-STYLE=best&RANGE-COLOR=&MAP-STYLE=

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.

References to NW in my earlier post are really NE. Long day yesterday!
