Although you really need the 727-100 Base Pack (csp721_2400.exe) to go with your 727-200 Expansion Model (csp722_2400.exe), there might be a way to get the textures to display.

Navigate to FSX\SimObjects\Airplanes\CS_B727-200\texture.xx (xx is equal to something like aircanada (texture.aircanada)) and open the texture.cfg file with notepad. It should show this:

[fltsim]
fallback.1=..\texture
fallback.2=..\texture\spec
fallback.3=..\..\CS_B727-100\texture
fallback.4=..\..\CS_B727-100\texture\bump
fallback.5=..\..\CS_B727-100\texture\night
fallback.6=..\..\CS_B727-100\texture\spec

As you can see, it is looking for the textures in the CS_B727-100 folder, but your folder is either a different name (I don't own the 727-100 Exterior, so I don't know), or the texture that ARE in the CS_B727-100 folder it is looking for are named differently and so it still can't find the ones it needs.

I hope you can follow what I mean.

I can almost reproduce the effect you see by renaming the Cs 727 texture folder which contains all the interior textures and in my case, some of the exterior ones too.



There are 106 files and three folders files in that folder.

I am struggling to understand why, when it is clearly stated that the expansion pack requires the base pack, you have asked this question?
