ORboarder Posted March 1 Posted March 1 It is highly possible that I am just missing something here, but I was shooting some ILS approaches just now and there appears to be an error in magnetic headings in the jet. The first approach was banak on kola which is a course of 352. When landed on the runway the jet is showing about 342, so my course line for the ils is off by about ten degrees. tried another one on Syria (ecran or something on Cyprus) which is an approach coarse of 295 but when landed on the runway I’m showing about 287. am I missing something in the sync process, or did the recent magnetic changes to the sim throw off every ILS and runway heading?
razo+r Posted March 1 Posted March 1 Where do you get your ILS courses from? And what date did you set your missions at? Banak for example should have, at least as of today, a variation of 13 degrees.
ORboarder Posted March 1 Author Posted March 1 I’m just using the ils course drawn in the mission editor which gives course and freq by the white ils depiction

I think the russians are fond of using true course instead of magnetic, and you know, many at ED are russian developers. Perhaps that white number is true instead of magnetic. Since it doesn't change with date, I suspect it is actually true course. Edited March 1 by razo+r 1

The jet is showing you magnetic heading. 342° at Banak seems like a correct magnetic heading for a mission set between 2006 and 2010 when the magvar was approximately +10° Edited March 1 by Minsky 1 Dima | My DCS uploads
Minsky Posted March 1 Posted March 1 (edited) In the Mission Editor, point anywhere in the vicinity of the aerodrome, and it will show you the magvar for this area at the bottom of the screen. Add/subtract it to/from the white ILS course to get the magnetic headings for this particular runway at this particular year. On the in-game F10 map, simply stretch the ruler parallel the runway, and it will show you magnetic heading in cyan: ...Or drag the compass rose over the aerodrome to see the the local magvar: Edited March 1 by Minsky 1 Dima | My DCS uploads
ORboarder Posted March 1 Author Posted March 1 Thank you very much. I don’t remember ever having to adjust an ILS course for magvar, but right there you can see it is runway 34 with an ILS course of 352 which should have been the big clue. 1
LG_Barons Posted April 3 Posted April 3 (edited) Always remember "east is least, west ist best" so you need to understand the meaning between MagneticHeading and TrueCourse MH /TC magnetig variation in the game is +10° (also 10°E) so 352° - (+10°) = 342° when you are on the ground. https://www.pilotmall.com/blogs/news/true-course-vs-true-heading-vs-magnetic-how-are-they-different cheers LG p.s. afaik DCS World is a Flat Earth. Real approach Plates do not always work. when flying approaches in the game from realworld data, the variation will be off. (so you need to find in your case, Approach Plate from 2006 or so. Course, bearings and headings are not 100% correct. The same for the "map origin", also not 100% correct. Edited April 3 by LG_Barons addtional information 1
