Title: Magnetic Precession on P-47N?
Post by: Stoney74 on October 14, 2006, 10:09:11 PM
Anyone else notice the approx. 8 degree difference in the wet compass and the directional gyro?  Haven't noticed it on any other Jug...

Didn't know if that was some sort of built in error for realism or just a gripe for the crew chief.

Maybe you got metal legs and they make the compass miss?

Brass is not magnetic.

Magnetic precesion??  Am LMFAO, in seat!! BWahaahaa!!
I haven't heard that word since taking my PPL test 50 years ago!
Checking for MP in AH2?  In all craft to see which has it, and which don't?  Instead of looking at the little GPS-Map and watching for nme to shoot at?

Stoney, you have GOT to be a CFI?  Yes?

(this will slay me all day!  MOOhahaaa!)

Just saying...It happens in the D-25 as well.  About 8 degrees difference.

Probably, but I just didn't know if was supposed to reflect some sort of historical deal or if it was just a bug in the model

If you can sit there and tell someone it "is 8 degrees off".   There are some issues that need to be dealt with.

I noticed it too Stoney... Just never thought about mentioning it....

So HT and Co is it a bug or a feature... :p

:huh  Magnetic Precession???

hmm... yeah, I've never heard of that before... but maybe you are all talking about "deviation" of the magnetic compass?

Bugs, your responses are too predictable that you Ignored, and I don't even need to see em.   But then again, I know who you are.   Too funny.

Gyroscopic precession, magnetic deviation, whatever.  Its been a while since my written.  Bottom line, wet compass and gyro don't match.  Haven't noticed it in any other plane but the Jug variants.

Perhaps this represents the "general deviation" of the average online gamre.

Well, Gyroscopic precession -=is=- an entirely unrelated topic when compared to  magnetic deviation of a standard float type compass..

The magnetic compass should be correct. The DG (Directional Gyro aka,.. heading indicator should then be set to your compass.

I don't know if it's really necessary as this is a -=game=- and not an instrument trainer, but it would be a nice touch to keep pilots sharp when navigating to targets to check the effects of precession on their DG.

Well, for a practical application--if me and my squadies are trying to fly a combat spread formation and I'm giving them headings, the difference can get us separated by a few thousand meters if we're not paying attention.

So, I've started actually calling which instrument headings will be issued from.  

Like I said, its a small detail that has little effect on gameplay--I was just curious as to whether or not someone knew why it occurred...

It might be a texture problem / bug, where the texture is not fitted correctly to the instrument, either the texture is of the wrong length (size) or the wrapping starts at another point as the texturer thought.

Yea,  "metal"; as in a boke mofo who could not afford brass, and purchased rusty balls on e-bay.

But, I decided not to say anything about that.
