Hi Richard,
this is an MSFS limitation. The reason is that the EIDW is outdated in the stock scenery. There is a missing runway and therefore the MSFS disable the terminal procedures.
Thats nothing what we can do sorry. This limitation exists since day one and there are a lot of such reports in the MSFS forum and here.
FAQ:
EIDW report:
As an option, what I have mentioned in the last posting. Use a 3rd party scenery, which reflects the real world. The terminal procedures are still included, so that would help to select the terminal procedures. By the way, there are over 250 outdated airports in the MSFS, so this can happen on other places too - it’s not limited to EIDW.
