Thanks for the follow up, what confused me about is how the aircrafts using the navdata, I thought both Zibo, Toliss and Challenger are using the default xplane navdata, which I got from the navigraph and put them into the custom data folder, and I also use the default scenery for the ZHCC which definity has RW12L/30R, so the problem is, where does the default aircraft read the navdata from? I'm gonna report this to the Laminar later today.
Thank you again.
