Map in editor displaced 10º with respect the in game scenery?

According the rule tool of the editor, both runways of Nellis are heading 40º, but in game the runways are heading 30º.

I have tried to make a simple fly with the F-5E: To fly from Nellis to Echo Bay following the adequate radial of the TACAN of Nellis. According the rule tool of the editor, this radial is 80º, 27 Mn.

I have started from 03 Runway, TACAN tuned, radial 80 selected with the CRS button, followed the radial carefully... and after 27 miles of fly, I´m in a point more than 5 miles South of Echo Bay. I fly North to Echo Bay, and exactly over the aerodrome I select the correct radial, that is not 80º but 70º. I have tried the same experiment using the TACAN BLD (Boulder) and LAS (Las Vegas). Same results. If I use the map of the editor (or the map of F10) and the rule tool, the inputs does not correspong with the correct places in the scenery in the game.

It´s a problem with the map of the editor, the scenery, the F-5E, or just I´m doing something wrong?

Magnetic Declination is 11º in Las Vegas and you're probably using the magnetic heading to fly your radial. The F10 map shows true heading.

OK. I see. Thanks a lot.
