Entering Pacific Co-ordinates

Recommended Posts

Hi Folks,Was wondering if anybody could help me showing me how I would put the below co-ordinates into the FMC for 747 & MD11. I've tried to use Wiki but couldn't work it out as far as finding the info and I've looked through some posts but couldn't find a relevant one.I do know there was one in the forum but again couldn't find it.I tried it by doing 3650E but that shows distance of over 15000 miles and also 3970N but again added more miles so I know I've done something wrong, appreicate any help offeredDCT 36E50 DCT 38E60 DCT 39E70 DCT 39E80 DCT 39N70 DCT 38N60 DCT 38N50 DCT 39N40 DCT 39N30Regards#Jason Thompson

Manuals are there for a reason. Check out the 747 FMC users guide page 30.Enter the waypoints in the format NXXEYYY.

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 = 33N303300N 13500W = 33N353000N 14800W = 30N48 0600S 17500E = 06S751100S 17000E = 11S701500S 16700E = 15S67 It's fairly simple to remember.It's either a North latitude or a South latitude' date=' paired with West or East longitudes; NW, NE, SW, SE.[/font']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 ) pacific_atlantic_fix_logic.png
