DMS vs DD lat/long in F10 map

Not sure where to best post this query.

The Decimal-Degree data on the F10 map is 7 digits (43*15.345).

I thought the typical DD config = (43.1535), with the number of post decimal digits varying with desired degree of accuracy.

More importantly, I'm finding that when one converts the Degree-Minute-Second data from the F10 map using DD = degree + (minutes/60) + (seconds/3600), it doesn't correlate with the DD data indicated in the F10 map.

I suspect I'm missing something. Any thoughts on this appreciated.

Hey Doc, I think the terminology here is just tripping you up a bit. DCS seems to handle the coordinates correctly, but it only outputs DMS and DDM (degrees decimal-minutes).

 

For example, I placed my cursor directly on the top of the “1” on runway 13 at Batumi. Without moving my mouse I recorded the DCS coordinates in the various formats.

 

DMS

N 41* 36’ 57.50” E 041* 35’ 26.21”

 

DDM

N 41* 36.958” E 041* 35.436”

 

To check this is correct we can take the seconds from the DMS and divide by 60

 

57.50 / 60 = .958 and 26.21 / 60 = .437

 

If we want to generate a DD we need to make the minutes from DDM into a fraction of a degree so we will divide the minutes by 60

 

36.958 / 60 = .616 and. 35.436 / 60 = .591

 

So DD

N 41.616* and E 041.591*
