Current navdata for the localizers of RWY 09/27 is wrong. The true bearing of the runway also is wrong. I currently use these coordinates and bearing:
4 42.694893 023.443320 1739 11070 18 94.64 ISL LBSF 09 ILS-cat-I
4 42.697939 023.392322 1745 10950 18 274.64 ISF LBSF 27 ILS-cat-III
They match the coordinates in the AIP file for LBSF and what can be seen on google earth.
It will be nice if XP's navdata is corrected because a new scenery based on the accurate coordinates was released yesterday - http://forums.x-plane.org/index.php?app=downloads&showfile=29715

You are correct - the current default data for LBSF is a detailed design that seems to be shifted about 50m - 100, to the NW from its real-life location. The current ILS data is designed to align with this incorrectly-located runway. Moving the ILS data to its 'correct' location (to align with the airport package published on x-plane.,org) will cause issue with the majority of users that use the default airport data. So, until LBSF airport is redesigned (in its correct location!), and uploaded to the Gateway, I will leave the current ILS data in its current (incorrect) location. There is no 'good' answer to this issue until LBSF is redesigned and submitted to the Gateway.

Hello Robin!
I have just uploaded a very light rendition of LBSF version 2 to the gateway. It is valid and I even put Terminal 1 and Terminal 2 in the scenery. The default scenery does not have any buildings at the moment.
Please let me know if this is sufficient for you to correct the ILS as proposed in my bug report (the numbers have been tested with full autolandings and work pretty well). If you think s.th. has to be removed from the scenery uploaded to the gateway, no problem. I really would like to see this corrected in the next version of x-plane - LBSF v2 has been downloaded more than 700 times for two weeks and it is a shame to ask the users to manually correct the navdata. Thank you for your understanding!
Best regards,
Mihail

That's a great compromise. I have added the correct ILS systems for LBSF for the next data release. I have also re positioned the SOF VOR.

Hi Robin,
it seems that this new 3d scenery is not yet present in the newest apt.dat file. Do you have an estimation when it will be included?
I am asking because after a discussion with Navigraph they don't wont to update the ILS coordinates in their data if the default apt.dat file does not have the correct runway coordinates ...
