No, it was not meant ironically. If it in due time would work as well as the animated jetways can work it would be a great feature that probably would scale well.

I do appreciate the complexity of it though. The jetways are complex, need a lot of configuration to work, both scenery and aircraft side, and I think there is a tool for placing them. In addition and to make them usable for scenery and aircraft developers there is also documentation.

As the ground services currently are mostly done aircraft side, there is probably very little commonality between them. The features that mostly are done FlightGear side probably also have rather little in common, as they nearly always was developed as descrete features by different developers. Integrating those in an extensible framework is no small task.

yes, the jetway editor is included in FG: AI->Jetways

And we can import jetway locations and headings for at least 340 airports from the gateway.
Here are the ICAO.jetway.xml files (FlightGear format) for anyone who like to use them:
https://github.com/mherweg/Airports

I did not yet suggest to include them in terrasync because at a few airports it will result in duplicate jetways
(AI and non-AI type)
here are more details:

About airport ground vehicles:
A while ago HerbyW and I did a successful Multiplayer-Pushback. The trick was, that one user had set his FG to "hot" and the other not.
--prop:/sim/multiplay/hot=true


At 2 airports I made cars driving around as AI scenario. But such AI scenarios live in FGDATA and are therefore hard to share with others :-( The current GUI dialogue for that is limited.

GSX ( for FSX ) uses gate and aircraft configuration to figure out how to position/animate ground services.

Initially those vehicles just spawn near the aircraft, if the gate is not customized they might as well spawn in the middle of the terminal building. If the aircraft is not customized ( no positions and angles for the door ) the vehicles will not approach the aircraft correctly.

The only thing that uses groundnets ( taxiways ) seems to be the followme car.

I just installed the latest Version (1.6) of WED (Wold Editor) and I noticed that you can define parking locations and AI networks for ground vehicles.

Currently we'd need a C++ developer to use this data for FG or a C++ developer that exposes those AI networks to Nasal and then Nasal Code that lets the cars & trucks drive around.

Well, good news.
I think we need to do several things connected to the ground services.

1) We'd want to have aircraft-independent ground services. This would require to make them a feature just as the jetways, meaning to make a dialog for toggling them in the general FG program and set the different vehicles. Then we need to program the aircraft for it, meaning to mark passenger doors, cargo doors etc., so that the vehicles can connect to the aircraft.
In this step, they can just appear anywhere next to the aircraft.
2) In the long term we can also set different ground networks for the airports. I think this requires really much time.

A problem also known with the jetway feature is, that very few planes and airports are equipped with it...
So very few people do really use it. We should definitely try to avoid this.

It's easy to do with WED.
As soon as it is possible to use WED 1.6 to upload to the gateway more an more of those networks will be uploaded.

looking at terrasync: you are right. Only KSFO has AI jetways.
Here are more details: http://wiki.flightgear.org/Animated_jetways

I have AI jetways for 382 airports here:
https://github.com/mherweg/Airports

I cannot upload them to terrasync because at some (few) airports it would result in duplicate jetways (AI and non-AI)
and at many airports they do not fit exactly to the buildings that we have.

I am planning for an advanced ground system that does similar to GSX in my MD-88/MD-90 series sometime. Perhaps I should make it available FGFS-wide?

@it0uchpods:

FGFS wide is better in my view as it is a generic feature many airliners might use. Same goes for things like RAAS that is discussed in another thread.
