Nevada map magnetic north

[NoJoy]

Can anyone tell me the magnetic north for the nevada map?

 

Have used the forum search with no luck.

According to the A-10C it's 12.3E on 1JUN2011 over Nellis. At different times and places it will be a different value. 1DEC2017 it's E11.7 in the same place.

 

And then there's always the fact that true north is not a path of constant longitude (which it is on the real planet). In DCS true north is whatever is up on the map which is only parallel to a line of longitude when on the central meridian of the terrain.

That used to be the case, but didn't that get fixed in the last year or so?

Nope. All modules I know of show 360 true when moving "map up" which is almost never constant longitude.

The reason why I was asking this was in regard to the 'Wind Correction' tool. I downloaded it from the DCS 'user files section'. I use the tool for almost every sortie for the Caucasus Map. It refers magnetic north to 353° as a standard value. Works perfectly to me.

 

So for me the question came up if I can use it as it is for the Nevada Map - which shows to work also. But for sure the magnetic north value is not the same though it won't really do a big difference for odnance delivery when being off some degrees but just to do it the right way I was wondering whats the correct numbers here.

 

I do know the real world geographical differences between true, magnetic and geographical north but in DCS is - as close as it is - is a different story, right?

It's something like 5E Caucasus 14E NTTR if you had to pick a single value. Given all possible times and positions the ranges are probably something like 4-7E and 12-15E respectively. The few degrees different is going to be overshadowed by all other sources of error.

 

A "000° 10m/s" editor wind should be a "175° 19.4kt" entry into a Caucasus A-10 and a "166° 19.4kt" entry into an NTTR A-10, roughly given a 5E and 14E variation for each.
