Nope no rocking it happened to me twice i turn onto finals and the system thinks it's right and goes in on the ils but just lines up 1 or nm to the left of the runway.

I find I need to manually change the course in the FMC to the stated FSX course and then all is well. Does not happen on all ILS's. Is there something I may be doing incorrectly?

Just my 2 cents...

In the real plane - having a course that is different than the actual ILS course is read by the system as a crosswind. That should not cause the plane to not be on the center line at touchdown since the needle being centered is what controls the alignment. You could have a slight heading difference since the computer would thing there is a slight crosswind.

Does the plane complete the auto-land approach and land on the runway, or does it try to land off the runway?

All the auto-lands I have done with the CS-757 have been fine.

Note: I have NOT up-dated the FAA database to current magnetic variation, but left the original FSX data as it was. I am still using the old version of the CS-757.

Thanks Lou, I have not let it complete an auto-land. The angle difference seemed to severe. I will let it complete sometime. I also did not think the course setting had an effect on the ILS, but this does not seem to be a crosswind type crab but a completely misaligned approach, even though the CDI is centered. If I manually set course, perfect every time. I have version 4.6 but have not updated database (can we do that?)

I think Mark and a few others have up-dated the original FSX database, I'll ask them to jump in here.

If you put in the wrong course the computer sees that as a crosswind. I've never seen a large error, but sometimes guys would be off by 10 degrees when setting the course in the 727 or 707 and it was hard to notice looking out the window. Since the newer planes set themselves from the FMS I don't remember any real problems with the auto flight system in those planes.

If the plane is misaligned a great distance to the center line of the runway there must be something bad in the database. Can you take a screen shot at around 500 feet and then 100 feet and post it?

I know that the original CYYJ (Victoria) localizer was off center. It was quite funny watching the plane land its self into a forest.... Wink

I found an AFCAD file on flightsim and that had a fix for the ILS.

Mark, if you do update your database, where do you download the new files? I have noticed that the FMC on 757/767 doesn't always have every vor or waypoint in its database, espcially when using an IFR flight plan form flightaware.com since that uses extremly recent flight plans.

I just made approach ILS34L into Denver. FMC Auto tune 111.90/351.
FSX has it at 111.90/350. I then manually changed to /355 for test. CDI centered and autoland made perfect landing. I think what I ran into early on in my CS 757 career was a bad localizer like at CYYJ. I then noticed the different Course settings and mistakenly assumed it was the cause and have been manually setting my course to match FSX ever since. I do not remember which approach it was but I will let auto tune run the show for awhile and see if I have any more alignment issues.

Would still be interested in any database updates, if there is such a thing.

Thanks

Bob

I added the updated magdec.bgl twice. But I didn't like it, so I no longer use it. I'm using the one that ships with FSX.
