Orbx has a post saying that they’re almost done with FTX AU AI Traffic Pack for P3D V4. All the aircrafts in this package has been put together specifically for P3D V4 platform. They do also support Dynamic Lighting as well as the LUA coding system. Many of the planes have nose wheel steering and some other niceties to be announced later.
One big change is that before the Cessna 177 was everywhere, it’s now changed. It will now show the correct model as C152, C172, C182 etc.
More info is available at Orbx’s website.
