Hi,
no, we are not the supplier. We (Navigraph) use Jeppesen as our data provider. ASOBO use NavBlue and convert their stock data by their own.
To your request:
We offer the correct ILS courses straight and offset (LDA) in our dataset. The issue here is, that the sim logic overrule these data and this logic can only be fixed by ASOBO. But as soon as this is fixed, you can expect perfect approaches.
Sorry, that we can’t help here more. The ILS courses are still set correctly in the AIRAC files.
