The ADEX files contain the airports for the float planes. Orbx has the same airport files so these
have to be above the Orbx files in priority. The Orbx airport files for the sea plane bases do not
have parking places and AI will not use those files. Here is the last two entries of my scenery.cfg
[Area.188]
Title=Dexter's Addon Scenery
Local=D:\FSX\Addon Scenery\Dexter's Scenery
Layer=188
Active=TRUE
Required=FALSE
[Area.189]
Title=Tongass Narrows AI Float Planes
Local=D:\FSX\Addon Scenery\Tongass Narrows Floats
Layer=189
Active=TRUE
Required=FALSE
Area 189 is where my ADEX files for the four SPBs are!
I hope that is clear as Mud
