Compass error

open beta (have not checked World)

on Grim Reaper server

The compass and header will say I am travelling at 270 (due west) where in fact I am travelling approx. 00 degrees (due north) according to map and unit selected information panel. Not sure the exact error in degrees about 90, happens with FC3 Su 25 T, not Su27 or A10A not checked other units in FC3.

No one else on GR server having similar problem so unit or me specific.

I have clear hud glass mod installed

Perhaps the place to start is to remove any mods (even if not Su-25T specific) and see if the issue is resolved.

You have to wait a bit when spooled up (or when electronics are turned on, I cannot remember) untill the navigation system is aligned. Then the compass reading will be correct in the Su-25.

You will notice once electrical system turned on that the HSI rotates rather quickly at first, and then begins to slow down before coming to a stop on current heading.

I haven't flown the 25T in some time, but in the past I would wait until the HSI stabilized on current heading before moving the aircraft. The wait time was somewhere between 1.5 to 3 minutes (again, been a while so can't remember exactly).

How long it takes depends on how far your parked heading is from due north. It’ll take the longest, if you’re facing south.

Thank you everyone for your advice, I will try all and see, fingers crossed :)

Try waiting 3 minutes after turning on the electrics before spooling up the engines
