Centerline descrepency

Post by wotaoyin » Fri Dec 21, 2018 12:44 am

Dear JP and friends,

I described a problem in another forum, http://aerosors.freeforums.net/thread/2 ... ollTo=1044, and I thought you might be interested and can help.

In short, I use http://www.aero.sors.fr/ to update magvar (the magdec.bgl file) and other navaids in P3D. I also have a navigraph subscription to keep my other databases up to date. None of these updates affects the magvar value in each of the 3rd-party (non-P3D) airport BGL files. Neither do they need to since the geographical coordinates of runways or their ILS stay unchanged. That is, after the update, the magvar value in the BGL files stay wrong but should not affect the sim. However, after each update, without re-building the airport database, FsiPanel reports runway centerline deviation even if the replay shows no deviation at touchdown -- I observed this problem on runways from 3rd party airport BGL files, for example, Orbx regionals.

I consulted Hervé in the above forum, and he thinks it is important to understand how FsiPanel determines centerline deviation, in particular, whether the magvar value is used, and, if so, which one, magdec.bgl or the one in the BGL file, is used.

Thank you!

I'm glad someone else posted about this, as I was just about to as well!!

Yep, Landing report ALWAYS says that I am always 'X' feet right from the the center line; even when on 'autoland'.
When I look from an outside view I'm 'spot' on the center line.

IF I manually land no matter where I land it always says 'X' feet right, never left, even if I go 'left' on purpose.

I've had this at LPPT, LIPX, LIRF, LIME and GCRR all 3rd party scenery with the MaddogX

Thanks

Clive

Hi,

I have to check in the code, I believe I'm using the data given by Makerwys which should be correct if a database update has been done after applying the magvar fix.

I will check and report back.

Cheers,

J-P

I'm coding now a new way to get the magnetic variation based on the updated magdec.bgl file, it should fix our issue hopefully.

I will post the beta when available to test it.

Cheers

Thanks a lot for the quick fix! That'll certainly make FsiPanel even better.

Hi,
You can try to download the BETA version of FSiPanel 2017 for P3D to see if the problem is solved.
You will find the link at the top of the forum.

Not an installer, simply replace your FSiPanel2017_P3D.exe with the new one.

Let me know if problem is fixed.

Cheers,

J-P

J-P,

Just tried the new beta and things are still not right. I have just done a CAT III at KVPS RW30 with a spot-on centreline autoland and the landing report gives a deviation of 28m right of the centreline on landing!

Hope you can identify things accordingly. Otherwise, thanks for the usual excellent support to us all.
