[FSLabs A321neo / MSFS 2024] Duplicate STAR waypoints at RJTT with AIRAC 2610

Navigation Data SID/STAR/APPR

Hi,

I’ve noticed an issue with the FSLabs A321neo for MSFS 2024 when using AIRAC 2610.

When selecting certain STARs at RJTT (e.g. XAC1K), every waypoint appears twice consecutively in the MCDU flight plan. This does not happen with AIRAC 2609, and the FSLabs version has not changed between the two cycles. I’m using the latest available version of the aircraft.

I compared the .rom databases using SQLite and found the following difference in the AIRPORT_PROCEDURE table:

AIRAC 2609: TRANSITION_IDENT = RW34B (one common transition)

AIRAC 2610: TRANSITION_IDENT = RW34L / RW34R (two separate transitions with identical waypoint sequences)

This change affects 20 RJTT STARs, including the AKSE, AROS, GODI, POLI and XAC procedures.

As a test, I modified a local copy of the AIRAC 2610 database to restore the previous RW34B structure. This resolved the duplicate waypoint issue with XAC1K.

I’ve attached a screenshot showing the duplicated waypoints with the original AIRAC 2610 database.

Could you check whether this change was intentional and if it might be causing a compatibility issue with FSLabs?

Thanks!

Hi Richard,

Thanks for looking into this!

Just a quick update: I also tested a STAR at RJBB (Kansai International Airport) and confirmed the same duplicate waypoint issue.

I checked the AIRAC 2609 and 2610 databases further and found the same runway transition structure change at several other Japanese airports, including RJAA, RJFF, RJOO, and ROAH.

It seems this issue may affect multiple airports, not just RJTT.

Thanks again!

Thanks again; it seems FSLabs has the same problem with multiple runway segments as PMDG :wink: … because this is new in our source (B-Runways are now split into multiple segments).

We have built a fix for this that restores the original state, and we are now using it in FSLabs as well.

Here, with revision 2:

I´m currently building the package and will upload it asap. Will inform you here when revision 2 is online, but you can expect it within the next couple of minutes.

Cheers,

Revision 2 is online … please go to the Hub and update the FSLabs add-on.

This should solve this issue (in general), not only for the example RJTT airport.

Let me know if I can do more for you & thank you for the report!

Cheers,
Richard
