Hello,
On RNP Y 19L approach to VECC via waypoint CC013. In the real world, and on the latest AIRAC CYCLE, the descent of 2.90 degrees is coded from CC013 onwards, and the Final Descent Point (FDP) is CC012. Whereas on the latest AIRAC cycle in Navigraph, the same approach, the descent angle is coded from the FDP, i.e., CC012. Why is that?
Thanks
Note: Simulation use is the TOLISS A320. The real world also uses JEPP AIRAC I suppose.

Hi,
Thanks for the report. I have checked our data, and it looks like a ToLiss issue or limitation because we have precisely the second picture in the data.
Possible that ToLiss interprets the data wrong, but I can’t see any issue with the data we offer. Please report this to ToLiss … you can reference my answer here. The source shows the CC013 with 2.9 degrees.
Thank you
Richard
Is the waypoint where descent starts being coded (CC013 according to both posts, if I understand correctly) indicated somehow in the X-Plane 11/12 native format used by the ToLiSS, or is it possible this specific information is not available in that format?
Regards,
Tim
Thanks for the reply. Any chance you could provide a screenshot of how the it looks in your database i.e. any other sim FMS, to compare?
The issue is on real FMS database for that airport, the descent of 2.90 degrees is coded from Intermediate Fix (IF) i.e. CC013. Whereas on my TOLISS A320 FMS , the descent is coded from the FINAL descent Point i.e. CC012
Hello, I wrote to TOLISS and lo and behold the reason was that they use only the Final Descent Point (FDP) to start descent. Also, in order to avoid starting another thread, could you check this airport VIDN, as per charts it has an ILS for runway 08 and on the TOLISS I could only see LOC ,VOR,RNP approaches for Runway 08. Thanks again and sorry for the trouble
The ILS08 into VIDN can’t be coded as ILS because the missed approach starts before the runway threshold and does not follow the runway heading. This is a standard ARINC424 rule, and we don’t offer airline-specific tailored records.
Therefore, it is coded as LOC08, but can fly this approach as ILS because the antenna (LOC and GS) is available.
It is the coding standard that does not allow it.
Cheers
Richard
