I heard about a Plugin for ground fueling / pushback / passenger boarding stairs, so I looked into it. The results of this Plugin are as follows:

The installation method is as follows: First, you need to install the OpenSceneryX Object Library for X-Plane® Plugin. You can download the installer from the URL below: OpenSceneryX Object Library for X-Plane® For example, select “Mac Installer” for download if you are on Mac, then just start “OpenSceneryX Installer.app”. Because it needs to download a large number of scenery maps from the internet, it takes quite a bit of time; it took me about 1 hour to finish the installation. There are many scenery packages that support OpenSceneryX; here there are scenery maps for hundreds of airports. It seems they are all free—a real treasure trove.

Additionally, it seems you also need something called “Python interface”, but we introduced it before, so you should have it installed already.

Then, generate a directory named “PythonScripts” and place it under plugins, for example like: xPlane / Resources / plugins / PythonScripts / Then just copy this file into that directory.

If you are using X-Plane 11, you can refer to the introduction to Pushback in X-Plane 11, as this version includes pushback functionality by default. Also, information regarding the scenery library can be found in this introduction.
