The WestWind Hub scenery for Salt Lake City may download from the Aircraft & Scenery download page. This is for FSX only! There are three scenery files available: A custom WestWind terminal that will not disappear at night; an Executive Charter terminal; and a WestWind Cargo area. I couldn't do anything about the disappearing default passenger terminal, so I decided to build a separate terminal for WestWind. A custom AFCAD file is included which provides coded gates/parking for WestWind aircraft. Here are a few screen-shots. More can be seen at the download page.
