For the SAK Sea Plane Bases Scenery that's currently up on the RTMM Scenery Page under "S, this is the traffic file included: Traffic_SAK_FSX_sea_planes.bgl.
For the new Lake Hood Float Plane enhancement, which requires a version of the Aerosoft Anchorage Airport Scenery, there are two traffic files and you will only need one of them inside your scenery\world\scenery folder of your simulator.
The file that Dex mentioned earlier is named: PALH_AFX-OP01.bgl
and is only for use with the "Professional" edition of the of Aerosoft PANC specifically made for P3D v4.
The second file inside the newer Lake Hood enhancement is named: Traffic_SAK_FSX_floatplanes.bgl
and this file is for users of FSX and all other versions of P3D only.
In looking at this, I'm now thinking we may have an issue that needs further testing and attention. So this is a question for Dex.
Dex, when you created this new Lake Hood file for the FSX/P3D edition of PANC, I remember you saying that it would overwrite the older SAK Seaplanes Scenery traffic file previously up on RTMM. I believe you said that because this new one was just adding the newer flight plans for Lake Hood that you made for this enhancement and not change the older traffic from the SAK Seaplanes.
However, the SAK Seaplane Scenery uses a different file name. So maybe that's causing some disruption in the traffic movement?
