Dear Tim
Thanks very much for this quick response.
In XP12 I am using the Toliss A339, but I have also tried, for this particular problem, the default Laminar A330 and the B737 so that I can see what those FMS’s are doing.
This is what I am seeing in my X Plane Custom Data folder, CIFP.
I don’t know enough about it to be able to interpret but I can already see differences compared with the database extract that you have provided.
Please let me know if there is anything else I can send to you or if this enough for you to see where it is going wrong.
Thanks for your attention.

I just want to add that I can now confirm that the download from Navigraph does not contain the approach LICR, RNP Rwy 33 (AR), as shown in the above extract.
I have made a new empty CIFP folder and done a fresh download of 2608 using the Navigraph Updater.
Hi Eddie,
This approach uses AF/RF leg path types, which require a center waypoint to calculate the turns/radius in the FMC. This center-waypoint seems to be missing, also on the charts and therefore also in the data. Therefore this approach can´t be coded at the moment (at least with our ARINC424 version, which we use). It could be that the AIP Italy will add this waypoint in one of the next cycles, but that is out of our control. At the moment, this waypoint reference is missing, but is needed to code the approaches for the FMC.
I do not want to contradict what you are saying but are you aware that this approach was present in Airac 2606, and previous.
My current understanding is that the real life aviation ‘Authorities’ have withdrawn this approach. Presumably this affected Jeppesen, from where you source your charts and this has had a knock on effect on the recent Airac releases?
Hi,
When this approach is withdrawn, it’s clear why it is missing. I haven’t looked into the AIP. I have only checked the data and the charts - therefore, my answer.
My apologies; I backup my navdata in a git repository, and it appears when I checked the files for the presence of this approach, my repository was in a middle of a bisect which I had forgotten to reset, pointing to an older cycle which did contain the approach.
Sorry for the confusion.
Regards,
Tim
Edit: FWIW, the approach was present in the data until cycle 2606 inclusive, and removed starting with cycle 2607. The coordinates for the RF center waypoints are not missing so much as they were removed along with the approach with cycle 2607.
The website does not know specifically why the approach was not picked up at the end of the testing phase, but goes on to speculate that it may have been due to lack of interest from airlines.
