I've got it working in FSX just in time for my simular timed tour too NZC, it really adds a whole new level of life to the sim. These were the instructions I followed to get it working:
* copy all folders in [FS9]\Aircraft starting with "HTAI" into [FSX]\SimObjects\Airplanes
* copy Traffic_HTAI_CSEP.bgl from [FS9]\Scenery\World\scenery into [FSX]\Scenery\World\scenery
The flightplan bgl file is in FS9-format, which will deactivate all your FSX-format flightplans, including default. Thus, you need to convert Traffic_HTAI_CSEP.bgl into FSX format using AIFPC -

Also, for me at least, the prop discs showed up as all black, so I made my own that I've attached below; you'll need to replace each instance of prop-hs.bmp in the aeroplane texture subfolders. The one I made is for a two-blade prop so you may want to add a different one for the three-blade variants.
Finally, you want to assign the appropriate sound files to each aircaft type. To do that create an empty "soundai" folder in each aircraft folder then copy the soundai.cfg file from the [FSX]\SimObjects\Airplanes\C172_LFH\soundai folder. For the bigger Cessnas replace the "C172" in the cfg file with "C208B" (use Wordpad or Notepad for that
there also are five "fx_ga_*" .fx files in [FS9]\Effects that you should copy into [FSX]\Effects."[/quote]
However, the 'Traffic_HTAI_CSEP.bgl' is called 'Traffic GNZLAP_REDUX.bgl' in this version. Theres also a file called 'Traffic_HTAI_NONZ.bgl' in the same directory which I copied too. They both need to be decompiled and recompiled (real simple and easy with the above linked tool) before being put into the FSX folder.
The soundai folder is the most time consumping part of the patch over, as theres all the different models of aircraft, but well worth the result.
As for the 'prop-hs.bmp', I couldn't find it anywhere on the net and Naki kindly emailed it to me. To save you time, I've uploaded it here:
