Plan-G using different magnetic deviation?

I discovered that Plan-G 3.1.4.129  has different ILS bearings than X-Plane 11.05; the X-Plane ones are correct (for X-Plane that is). Just a few examples:

Nanaimo CYCD 16 ILS bearing is 165o, Plan-G shows 162o.
Springbank CYBW 35 ILS bearing is 346o, Plan-G shows 343o.

It finally explains why I missed the runway when I used the Plan-G ILS bearings.

Tim, do you not use the magnetic deviation table from X-Plan 11.05 when you build the X-Plane 11 database?

Please try build 137 at the top of the forum.

Hi Tim,

I did a clean install of 3.2.0.137.

I rebooted my PC, rebuild the database which took a surprising 37 minutes, and the two ILS still have the wrong course.

Hmm. That's odd. It worked in 136, wonder why it reverted in 137. I'll investigate.

Tim,

Just out of curiosity I downloaded you limited database https://1drv.ms/u/s!AkfXrd8YzuWwgRMw3XyqOZrTXFO4 from the 3.2.0.137 topic. I used it and checked CYBW ILS and it is there also wrong (343o). That of course makes sense if you generated it with version 137.
