cquail Posted March 24, 2013 Posted March 24, 2013 In the latest DCS 1.2.3 patch it says the Russian aircraft HSI being off centred was supposed to be fixed. I'm finding the HSI is about 6 degrees off on the ground and then increases up to 30 degrees while airborne! I've tried everything from waiting 3 min on ground to align, cycling nav modes, etc. Nothing helps. So what exactly was fixed in the patch?
NC_Cyborg Posted March 24, 2013 Posted March 24, 2013 I noticed the same thing tonight. I thought it was a little odd myself. 'NC_Cyborg' [sIGPIC]http://forums.eagle.ru/signaturepics/sigpic88701_1.gif[/sIGPIC]
Weta43 Posted March 24, 2013 Posted March 24, 2013 What plane, and how long till it 'drifts' (just tried a short fligh in an Su-25A & it was fine) ? A track ? Cheers.
Dr_Arrow Posted March 24, 2013 Posted March 24, 2013 I've also flown about 30 missions in Su-25A with 1.2.3 and haven't noticed any HSI drift. What bothers me with HSI is only automatic waypoint switching, because using one waypoint as a target is very bad for reattacks, could this be made optional?
NC_Cyborg Posted March 24, 2013 Posted March 24, 2013 (edited) Sorry for the confusion. It is the Su-25T. From a ramp start and in the air I noticed a 5~10 degree difference between the HSI and the HUD. I just started flying the Su-25T within the last couple of days and noticed it today.

cquail Posted March 24, 2013 Author Posted March 24, 2013 (edited) Su-25T for sure. One of the other guys I was flying online with was having the same issue, he was about 20 degrees difference. It is also always a negative difference. I.E. - the HSI is always less then the HUD heading. -5 to -30. Not sure if the heading in the Su-25A is any different as we have no other heading indicator inside the pit to compare it with. As far as how long till drift occurs, it seems to happen very shortly after take-off. I wonder if it occurs after your first turn/banking action after airborne. The HSI lags significantly behind your actual heading and seems to never re-align properly. Edited March 24, 2013 by cquail

At 41+26 you will see orange smoke. As I fly over the smoke I am on the 177 radial at 16.5km. The needles read as the 157 radial.

cquail Posted March 25, 2013 Author Posted March 25, 2013 Tested out the Su-25A last night. Both of us lined up on the runway and compared HSI headings. Mine was over 100 degrees different from his. loaded up another aircraft and was flying 110 degrees according to the HSI, but was actually on a heading of 340! Something is very messed up.
cquail Posted March 27, 2013 Author Posted March 27, 2013 I've continued to test both aircraft. If I air start the HSI is accurate, if I start on the ground its about 100 degrees off. Something must be corrupted somewhere. Any ideas?
wilsonov Posted April 9, 2013 Posted April 9, 2013 I occasionally have the same problem......... :thumbup:
osram Posted April 9, 2013 Posted April 9, 2013 The only thing I know, is that the HSI can deviate from readings if someone somehow rushes startup and doesn't wait for the needles to center. Other than that, it sounds like a bug.
