Yes, sure!
The apt.dat file is on the X-plane scenery gateway, link here:
http://gateway.x-plane.com/scenery/page/ZSPDDownload the version marked with a star, then unzip the file
Open "Earth nav data" folder and you shall find it
To make it usable in FG, create a folder named NavData in your custom scenery folder, then create another called apt in the NavData folder
Drag the apt.dat inside and you're good to go! (I recommend renaming the apt.dat file to ZSPD.dat
If you want, I can pull a request on the ZSPD repo and add the apt.dat file there.
Best regards,
Mars.
