User Waypoint Lat/Lon position Displaying Incorrectly

[MackemSam]

I hope you'll forgive me for asking, and apologies in advance as this is likely due to operator error, ie: me! I'm new to Plan G and have been attempting to add a user waypoint to my map. The actual process is simplicity itself however, once activated, the waypoint displays in the wrong position, which I presume has something to do with how I entered the Lat/Lon data.

The waypoint in question:

JUMKI, which is a REP-PT on the departure from Wrangell (PAWG), Alaska. I have a couple of sets of data for JUMKI, but they all display incorrectly in Plan G: The Level Island Two Departure plate for PAWG lists JUMKI as being at N56* 28.34' W132* 25.33' whereas MyAviationInfo Navigation Fixes puts JUMKI at 56-28-20.410N 132-25-19.540W, and openNav shows JUMKI at Latitude 56° 28' 20.41" N Longitude 132° 25' 19.54" W (it's in the correct position on their map here: http://opennav.com/waypoint/US/JUMKI namely, in the water of the bay just to the west of PAWG).

Trouble is, if I enter any of those sets of co-ordinates in Plan G, when JUMKI shows on my map, it's located south-south east of Wrangell on top of a 2930 foot high mountain, and as you're supposed to be able to overfly JUMKI at 1000 feet, that can't be correct; I'm using VFRmap.com for my Sectional. I've tried entering the data like this (using the Lat data as an example): either as 56.2834 or 56.2820410, but both give the same, ie: wrong, results.

My question is this, how do input the Lat/Lon data so I get JUMKI to display in its correct location?

Many thanks in advance for any assistance you're able to offer.

Kind Regards,
Sam

Sam,  you need to do some math to get the correct values for entry..

Lat whole degrees + (lat minutes / 60) + (lat seconds / 3600)

N56* 28.34'  = 56 + (28.34/60) = 56 + 0.472333 = 56.472333
56° 28' 20.41" = 56 + (28/60) + (20.41/3600) = 56 + 0.46666666 + 0.0056694 = 56.47233604

Use the same formula for longitude.

Positive numbers are North/East while negative numbers are South/West.

Much appreciated, Roman. See, I knew it'd be something simple...me!  ;) In all seriousness, thank you. In the real world I'm so used to prodding my GPS screen and off I go that it's years since I had to actually do some maths first. Right, I'm off to have another go at JUMKI.

Kind Regards,
Sam
