GE Propulsion Testbed Boeing 747-400 for the AIA Boeing 747-400D base model.
These are textures only. The AIA Boeing 747-400D base model is required.
It can be found at www.avsim.com. Search for ai74dupg.zip.
Please note that you have to use the 747-400D model. This is because GE have removed the winglets from the plane. The plane was build with winglets, but now it’s flying around without winglets. But since this has not been made as an AI model, you have to use the closest, the 747-400D model.
