how to remove/de-activate a certain airport

[trazee]

im refering to hongkong's VHHH...i want only kai tak VHHX operational as add-on (9 dragons)l, but the default airport is VHHH, with the new 9D scenery installed, without removing the default airport, the AI traffic has nowhere to land.

[skylab]

It's all in the instructions under "Getting Started - Installation".

i managed to de-activate VHHH, and routed all AI traffic to VHHX, but one more thing seems unresolved, AIs coming in for landing, will not land at all, it approaches runway 13 (checkerboard), it will only fly past the runway about 300ft, then regains altitude
