Hi,
I do not fly the aircobra frequently but after 1.22 I realized that the horizon line in the attitude indicator in the N series a/c does not align correctly with the aircraft marking on the indicator. It makes an angle of 10 or so degrees.

Does anyone else noticed this?

I haven't checked out whether the same problem exists on Q series.

Do you mean item number 5 on this cockpit reference?

That is the artificial horizon. I haven't noticed anything odd about it. If you mean a different dial, refer to that diagram and let us know.

Yeah, I mean the artificial horizon (I think this is the old term for this instrument)

I meant that the small vertical line (seen at 12 o'clock position on the cockpit reference pic of mudmover's) doesn't align with the 0 degree mark on the indicator. The top part of the indicator has 5 indicator marks to denote wing-level position (0 deg bank mark), 30 deg left, 60 deg left, 30 deg right and 60 deg right bank angles. On other US planes (p40s P47s and P51) there are no such a problem.

It's okay to use old terms when talking about old airplanes. http://ubbxforums.ubi.com/images/smiley/16x16_smiley-wink.gif But I believe artificial horizon is still currently in use today.

So when you sit with the engine running on a runway, do you still find that the mark doesn't line up by about 10 degrees? That's a rather large angle...

Sorry I don't have FB available right now.

(10 degrees is a bit exagerated I think but I am sure it is greater than 5)

I first observed that while airborne and yeah, I started to check it flying straight and level, engine turned off, magnetos off and finally on the runway. There was no difference.

Anyways I am at work now and I will check back once I return home.

I'll have to check it too, though I probably won't have time until Thursday.

I have also noticed this - feels like you kinda have to crab a little right trim to fly a straight line. If you try to fly a straight line without trim - you can see a difference between the (real)horizon and the artificial (inst.) horizon. she kinda drifts to the left.

I'm not entirely sure what you're talking about, but if it's a needle that points up at a mark on the dial (and there's a little ball below it), that shows if your rudder is trimmed properly or not. If it is, the needle will point directly at the mark.

Tap Ctrl Z and Ctrl X to adjust it. You'll find it also affects your horizontal attitude as ahown on your artificial horizon. You also have to to tinker with your aileron trim to get everything lined up. In fact, in the Hurris there is no aileron trim, so you adjust both roll and yaw trim with the rudder trim.

Again, I'm not sure if this is what you're talking about. Sri if I'm completely off base.

Okay, I've just had a look in game. The whole gauge actually seems to sit somewhat to the left in its housing. Look at the horizontal line that actually represents the horizon. The left side comes closer to the edge than the right side. The problem is not that the horizon is off or at some angle in level flight, but the perception shows it sitting to the left. This could actually be an intended representation of depth perception of the gauge.

tttiger, if you don't have the game handy, check out the cockpit reference I linked to. It's item number 5, the artificial horizon, not the turn-and-bank indicator.

The same behavior in the Q models.

This is not in my opinon any kind of real problem, we're talking about a difference of maybe 2 degrees max. To get absolutely level flight in low-visibility conditions, line up the horizontal lines. The mark at the top is for when you are in a bank, and the 2 degrees don't make an appreciable difference.

Thanks for pointing this out. http://ubbxforums.ubi.com/infopop/emoticons/icon_smile.gif

Yeah, I have looked to the game to and also noticed the same in Q series as michampa did.

But I don't agree with you on its (possible) intentionality.
If you look at other artifical horizon indicators on other american a/c's you'll see that there is not such a thing in P40's and P51's indicator. The instruments are identical in each plane.

Then I guess Oleg or someone just recognized the Cobra's right to be unique. http://ubbxforums.ubi.com/images/smiley/16x16_smiley-very-happy.gif
