Offset (ILS / LDA) Approach Issues

Ah! Yes, this is a problem with the default nav data. The default data has the wrong ILS course assigned to the ILS 22R transmitter. The transmitter is located in the correct physical location in the scenery, but the localizer heading is incorrectly set to the runway heading of 223 degrees instead of the actual r/w localizer heading of 221 degrees.

In order to solve this, it is necessary to use the Navigraph core nav data replacement for the MSFS default nav data, Navigraph sets all localizers to the correct published heading, while the default nav data sets all localizers (with few exceptions) to the exact runway heading. This is fine in most cases, but if the localizer is actually offset, it will guide to to a landing alongside the runway.

When the ILS22R is used with Navigraph core data, the aircraft approaches the runway at an angle from the right side, and comes even with the runway centerline at the MDA altitude of about 250 feet AGL.

If you are already a Navigraph subscriber, there is no additional charge for the replacement data for MSFS, however if you do not subscribe to other Navigraph services, the MSFS replacement data would not be free.
