how enter the LAT/LONG coordinate in PMDG MD-11 FMS

Recommended Posts

hi all fans, 

how enter the LAT/LONG coordinate in PMDG MD-11 FMS,

ex :  4500N 01500W

i have try N45W015 then enter  answer not in data base so if possible how ??

so thnx a lot for help. 

:mellow:

Someone should really update the manual. I got fed up the other night and shut down the sim. I think the manual stated entry as NxxWxxx in fact I read until I found it again. And to no avail would it take the code. Not in data base. Thanks for the answer and PMDG should square this away in the manual. FMS.10.16 is where I found the above. Cpt out.

4515N is an RNAV waypoint, exactly the same kind of waypoint that RIVET is, or any other 5 letter waypoint.

 

It happens to be located at exactly 45N015W.

 

Also try:

 

N4500.0W01500.0

 

on the MD11, it appears the decimal point is always neccicary. Not on the Boeing.

FMC Lat/Long Coordinate Coding

Posted 05 May 2011 - 09:42 PM
N latitude, W < 100 degrees longitude = xxxxN
(eg: 6040N = 60N 40W)
N latitude, W > 100 degrees longitude = xxNxx
(eg: 50N20 = 50N 120W)
N latitude, E < 100 degrees longitude = xxxxE
(eg: 4507E = 45N 07E)
N latitude, E > 100 degrees longitude = xxExx
(eg: 12E21 = 12N 121E)

S latitude , W < 100 degrees longitude = xxxxW
(eg: 1041W = 10S 41W)
S latitude, W > 100 degrees longitude = xxWxx
(eg: 05W60 = 05S 160W)
S latitude, E < 100 degrees longitude = xxxxS
(eg: 0233S = 02S 33E)
S latitude, E > 100 degrees longitude = xxSxx
(eg: 14S11 = 14S 111E)

Example: (taken from KLAX to YSSY United flight on FlightAware)

From the above route:

3300N 13000W = 33N30
3300N 13500W = 33N35
3000N 14800W = 30N48

0600S 17500E = 06S75
1100S 17000E = 11S70
1500S 16700E = 15S67

It's fairly simple to remember.
It's either a North latitude or a South latitude, paired with West or East longitudes; NW, NE, SW, SE.
If the West/East is greater > 100 degrees, the letter modifier will always be in the middle of the fix (xxNxx)
If the West/East is less < 100 degrees, the letter modifier will always be at the end of the fix (xxxxN)

North lat + West long = N as the modifier letter ( xxxxN / xxNxx )
North lat + East long = E as the modifier letter ( xxxxE / xxExx )
South lat + West long = W as the modifier letter ( xxxxW / xxWxx )
South lat + East long = S as the modifier letter ( xxxxS / xxSxx )

-------------------------------------------------------------------------------------------

To code in custom Lat/Long corrdoinates it depends on the values of the Lat/Long. In your case, the coordinates will be entered like this:

5700N 10000W = 57N00
5930N 09000W = (not sure about 5930N 09000W but 5990N = 5900N 09000W)
6100N 08000W = 6180N
6300N 06000W = 6360N
6300N 05000W = 6350N
6200N 04000W = 6240N
6000N 03000W = 6030N
5700N 02000W = 5720N

I have used this coding repeatedly in the 744 and MD-11 FMC's crossing the ponds. I had this question myself several years ago and was lucky enough to find the post that I qouted above. (I copied it for my own future use.) Hopefully this will answer your questions.

Additionally:

If you recall, you always enter the initial position on the INIT REF/PERF INIT/INIT (INIT for the MD-11) page.  When selecting the initial position from the GPS coordinates provided note the format.

 

While each system uses a distinct format, you've been entering it all along, but never thinking twice about it.  Always pay attention to the data the computer uses for itself. 99% of the time, that's the data it wants from you.

 

Just a tip for learning new aircraft, or if you forget  :wink:
