When you enter the route it needs to read as such;

4800N 05000W = 4850N or N48W050

5000N 04000W = 5040N or N50W040

etc

Not for LAT/LON coordinates.

4800N 05000W 5000N 04000W 5200N 03000W 5300N 02000W.

Would become.

48N050W 50N040W 52N030W 53N020W.

Lets take 4800N 05000W  for example.

4800N 05000W.

Becomes 48N050W.

Go to this website.

http://www.simroutes...ParseRoute.aspx

Enter :

Departure: YSSY

Route: 3343S 15202E 3300S 15500E 3041S 16300E 3000S 16500E 2900S 17000E 2800S 17500E 2700S 18000E 2500S 17500W 2200S 17000W 1800S 16500W 1300S 16000W 0815S 15700W 0500S 15500W 0200N 15000W 0900N 14500W 1600N 14000W 2100N 13500W 2600N 13000W 3000N 12500W

Arrival:KLAX


Like so and press generate. Then export that flightplan. If you had PMDG you would choose PMDG .RTE and it would go into the Program Files\Microsoft Games\Flight Simulator 9\PMDG\FLIGHTPLANS part of the folder. You would then enter YSSYKLAX in the COROUTE of the FMC.

I was having trouble with this a few months back. But in the end I managed to make it work. My last flight using a Westerly (NAT) was a few days ago from EGLL to KIAD. From Heathrow, I departed from 27R on a WOBUN 2F 2G BUZAD 3J 2K. The (NAT) I used for this flight was GOMUP 59/20 59/30 59/40 58/50 PORGY HO. But you have to enter the coordinates in the fmc like this 5920n 5930n 5940n 5850n. Hope this helps.  :hrmm:

Oh, forgot to mention, I was using the Level-d 767  :hrmm:

Ian.

Being an experienced 744 Pilot, I will en part some of my wisdom upon you guys. Lets look at a recent flight plan between YSSY and KLAX

NOBAR B450 ABARB B450 TEKEP B450 NF 2800S 17500E 2600S 18000E 2400S 17500W 2100S 17000W 1800S 16500W 1500S 16100W MEGOG B200 PUMIS B200 BISOX B200 ANJJE 1000N 14200W 1500N 13800W 1900N 13500W AMATT 2800N 12500W FICKY C1177 SXC

The 1st coordinate is 2800S 17500E can be input as 28S175E,
next waypoint is 2600S 18000E which again can be inputted 26S180E

Next waypoint to look at would be 1000N 14200W can be inputted as 10N42

In terms of other flightplans in the thread Ive picked up 0815S 15700W which can be input as 15W57

Il say now that not all of them will work being input into the RTE page on the FMC, and might have to be entered into the Legs page.

Cheers

Tim

Sorry just realised my mistake above regarding the SID from Heathrow. It was a (WOBUN 2F) from 27R not a (WOBUN 2F 2G) The (WOBUN 2F) is the 27R departure and the (WOBUN 2G) is the 27L departure.  :P :hrmm: :hrmm:

Always remember that the FMC and IRS reads LAT/LON coordinates in the degrees minutes and seconds format. LAT/LON coordinates are drawn out so that 1 degree of longitude and latitude takes an hour to travel at 1 knot. Degrees of longitude and latitude are divided by minutes and seconds. There are 60 minutes in a hour and 60 seconds in a minute.

Take your first set of coordinates,

33 degrees and 43 minutes south becomes S3343. We need to add the longitude coordinates to complete the waypoint. 152 degrees and 2 minutes east becomes E15202. The completed waypoint will be S3343E15202.

The next waypoint will be entered differently because it represents where a parallel meets a meridian, as in there are no given minute or second coordinates. 33 degrees south will turn into S33. Then combine it with the longitude coordinates of 155 degrees east to come up with S33E155.

You gave the Airbus format for LON/LAT coordinates. :hrmm:

Boeing FMC's read direction/degrees/minutes/seconds whereas Airbus and MD FMC's read degrees/minutes/seconds/direction.

On the 744 1000N 14200W would be N10W142 (remember that east and west coordinates are 3 digits as the prime meridian isn't drawn around the entire circumference of the earth).

Yeah, but the FMC won't take the coordinates if you placed them as 10N142W (I get the invalid entry message when I try to put the coordinates in like that). PMDG and LDS FMC's need the format as N10W142.


BTW, the part I placed in parentheses in my last reply wasn't aimed at you. :hrmm:
