VTJS17_Fire Posted September 1, 2016 Posted September 1, 2016 Hi, in our last training flights, we discovered a bug in the NAV and cNAV logic. Waypoint 1 = Bullseye; cNav selected; Bearing in HSI and VTB are same (true heading for both) Waypoint 1 = Bullseye; Nav selected; Bearing in HSI is 130° (magnetic heading) and in VTB 140° (true heading) As you can see, the bearing information in the VTB remains the same, whether I select cNav or Nav. As you can see too, the heading band in the bottom of the VTB changes to the correct mode. Bug found in the current open alpha version of DCS.

Azrayen Posted September 1, 2016 Posted September 1, 2016 I also have doubts about the HUD/HSI, saw a weird discrepancy last night (not always present), didn't had time to fully investiguate yet.
david.lind Posted September 1, 2016 Posted September 1, 2016 What does the Magnetic variation state in the INS?

david.lind Posted September 4, 2016 Posted September 4, 2016 Should be 12° according to the ME and real Charts. I asked because changing year in ME changes the value.
Frederf Posted September 4, 2016 Posted September 4, 2016 Declination changes over time for a given location. Any operational chart and DCS will include corrections of first and possibly more orders of correction relative to some date. http://www.teara.govt.nz/files/di-9218-enz.gif
VTJS17_Fire Posted September 4, 2016 Author Posted September 4, 2016 I asked because changing year in ME changes the value. I didn't know, this is simulated. Nice to know, thanks! 12° was for December 2013 with 0,1° W change rate per year.

Sarge55 Posted September 4, 2016 Posted September 4, 2016 Cool, the annual declination change is simulated, didn't know that either. [sIGPIC][/sIGPIC] i7 10700K OC 5.1GHZ / 500GB SSD & 1TB M:2 & 4TB HDD / MSI Gaming MB / GTX 1080 / 32GB RAM / Win 10 / TrackIR 4 Pro / CH Pedals / TM Warthog
Zeus67 Posted September 6, 2016 Posted September 6, 2016 Cool, the annual declination change is simulated, didn't know that either. Yes. DCS stores magnetic declinations in a table that is updated regularly.
