According to Freddy “WED 1.6 is in public beta; you can try it and experiment with new X-Plane 11 features, but you cannot yet upload to the X-Plane Scenery gateway; we will open the gateway for X-Plane 11-compatible uploads once we have done more testing on WED itself.”
Yet, one can experiment the new features, including what I would call “dynamic static aircraft” since they will be serviced, will taxi, take off and land. In addition you can assign them the ICAO code of their airline, type and size. You can select them with the ramp start tool.
Two new tools have been added for creating “ground vehicles traffic”, one is the departure tool, the other, the destination tool for push back, trains of luggage, catering, … The traffic pattern is implemented with the ATC tool, you just need to select “ground” instead of “aircraft”. The WorldEditor manual doesn’t give you enough tutorial material. You will have to experiment a bit and go through some aggravation at times. Also, don’t expect the traffic to work perfectly, it’s still in beta. Vehicles will act out, bump into each other and cross buildings. Dynamic static aircraft is only available to two dozens of aircraft and airlines.
