Hi,
sorry for the very late answer - I have overseen to answer it - big sorry.
The reason why this approach isn´t included is because it can´t be coded. When you look on the charts, you see that the missed approach starts prior the runway-threshold. Normally, such procedures will be coded as LOC only approaches, when this approach can be used as LOC approach too.
In this special case, it´s ONLY and ILS approach, so no “ILS or LOC” approach. An ILS approach needs the LOC and GS-part but when the missed approach starts prior the runway threshold, Jeppesen doesn´t code this in their standard database. Possible that some airline tailored data are existing, but we haven´t access to all of them.
Here the difference between the “ILS-Z” and “ILS or LOC R” approach
ILS-Z only:
ILS or LOC:
Therefore, no ILS-Z 15 approach available, sorry for that
Cheers
