I finally got this aircraft to start. Here is what I did:
I noticed that there were 2 .air files in the folder; b727.air and b727200A_vl.air. As installed, the Aircraft.cfg used the b727200A_vl.air, so I decided to try the b727.air. that one did the trick. I don't know what the differences are, but it works and I can fly the aircraft. Here is what you need to do to make the change.
Open the Aircraft.cfg file with notepad and change parameter sim=
Here is what the first 3 lines should look like:
[fltsim.0]
title=WestWind Cargo Boeing B727-200F
sim=b727
Save the edited file. The 727 now works like any other aircraft. It loads with the engines running and will start either manually or automatically using CTRL+E
