Hello,
are the FMS data for Kai Tak (Prosim737 2.24b1 and above) no more longer available?
It would be nice to maintain this amazing approach by using the FMS/CDU.

Hi Brian,
can´t really say why the VHHX (old Kai Tak) can´t be selected in the ProSim FMC, but what I can say is, that this tailored airport is included in the database. Here are the terminal-procedures directly from the database:
Possible, that ProSim checks all database airports against the existing sim airports and VHHX doesn´t exist in the default sim data. But again, I´m not 100% sure what the issue could be - but VHHX is included as you see.
Cheers,
Richard
