I've been using this Kai Tak scenery from flishtsim.to for a while, but I noticed an issue with the navdata.

I use in-sim navdata on the A350 to prevent WASM crashes and flight path deviation/flight freeze. I planned a flight from RCTP to RJAA which the SID lead me to MOLKA M750 MUKEP. I entered the route into the FMS but it didn't recognize the route. While I understand that the Kai Tak scenery does have its approaches and navdata, which in my sim appears to override the jeppesen data. When I disable the Kai Tak scenery, the FMS recognize the route correctly.

Up to this point, the problem seems to be the scenery, until I enable the scenery again and tried the same route on the default 737, as well as the FBW A380, which they all recognize the route correctly. Only the default aircrafts made by Inibuilds, as well as the A340/A350 does not recognize the route correctly. It looks like there is an issue on Inibuilds' aircraft when it comes to reading the default navdata, can the team please take a look?

Hi, this is an interesting one that I'll pass on to the team to ask about, if I understand this correctly, when having a freeware KaiTak installed, the arrival in Narita gets messed or the entire route? And only in Inibuilds A340 and A350, as well as the Default Airbuses by Inibuilds interesting, can you send footage of you programming the route on the ground as I don't really know what correctly is supposed to mean in this regard other than the programmed route connected from end of SID to STAR. Thanks

The aircraft does not recognize the route "MOLKA M750 MUKEP", and probably onwards. When entering M750 after MOLKA, the page did not respond; whereas with the scenery off, it will recognize M750 MUKEP. Really strange to see other aircraft working without issue too.

It is very easy to recreate, install the Kai Tak scenery, load the A350 onto RCTP, ensure in-sim navdata is selected, enter a MOLKA SID, then from MOLKA, you shouldn't be able to enter M750 MUKEP. Then, load into the same scenario with a default 737, programme the same route, you will be able to enter M750 MUKEP.
