• Which the release of FS2020 we see an explosition of activity on the forun and of course we are very happy to see this. But having all questions about FS2020 in one forum becomes a bit messy. So therefore we would like to ask you all to use the following guidelines when posting your questions:

    • Tag FS2020 specific questions with the MSFS2020 tag.
    • Questions about making 3D assets can be posted in the 3D asset design forum. Either post them in the subforum of the modelling tool you use or in the general forum if they are general.
    • Questions about aircraft design can be posted in the Aircraft design forum
    • Questions about airport design can be posted in the FS2020 airport design forum. Once airport development tools have been updated for FS2020 you can post tool speciifc questions in the subforums of those tools as well of course.
    • Questions about terrain design can be posted in the FS2020 terrain design forum.
    • Questions about SimConnect can be posted in the SimConnect forum.

    Any other question that is not specific to an aspect of development or tool can be posted in the General chat forum.

    By following these guidelines we make sure that the forums remain easy to read for everybody and also that the right people can find your post to answer it.

MSFS20 AI aircraft stops on runway. How to build path for runway?

Hi,
I have taxiway paths from parking to runway centerline. AI aircraft taxi to runway and stops.
Next AI plane behind just ignore the the first one doesn't stop on hold short ILS, taxiing to runway and stops on the same position where the first one.
If I connecting two taxipoints on both ends of the runway with the path "RUNWAY" the behavior is the same.
What is wrong? How to build the path from parking to runway for AI plane takeoff?
 
You need a hold-short node on the taxiway which connects to the runway.
 
George, not sure I understand it correctly...
A hold-short node on the taxiway is not a problem. How to connect it to the runway?
Create path? Between hold-short node and what?
 
You need to link your taxi paths to the runway. They need to be connected.

The path on the centreline of the runway needs to be type runway and the paths joining it are type taxi.

You will also notice that the runway path has to be given a number associated with the TE number.

What I ended up doing was splitting the runway path into sections, some sections were RW22 at the Runway 22 end, at the other ent it was 04. This ensures the AI can get to the appropriate end of the correct runway.

Perfect! Thank you very much!!!

This is how it works: between runway and hold short node (not ILS hold short) should be ONLY ONE section path type TAXI.
Runway should have a straight path type RUNWAY. As you mentioned, it should be splitted for two pathes for bi-directions runway. Each path should have corresponded runway number.
So, connecting the hold short node with the runway path node and that's it. It works!

My mistake was in the accurate taxiing pathes, while for AI traffic it should straight (angle 90'). AI itself will make a smooth turn to the runway.
 
Interesting.
So to actually create good looking taxi "painted" lines you would use paint lines?
Because a 90 degree corner would make some ugly looking paths visually

Does this "runway" path need to be linked/connected somehow to the runway as well or should it just be in the center?

And If I understand correctly, i make one line to the Hold location?

Right now I'm using multiple nodes (all type taxi) to go to the center of the runway
 
You can have more than one section of TAXI between the hold shorts (in pink) and the RUNWAY paths (in red). TAXI paths marked in green

You must have a taxiway connected to the runway centre-line. There must be a hold-short node before the node on the taxiway and centre-line.



Note. The above is very stylised, in fact there are two coincident pathways, one connected to the parking spots "taxi-in" direction and one connected to the "taxi-out" direction.

If you look at AI plane behavior, you will see that it use its own path between hold short node and runway lineup.
So, most probably any extra nodes between hold short and runway are ignoring. At least, this is what I see in my airport...

Yes, AI plane uses its own path between hold short node and runway lineup. I tried few different methods and AI always ignored my paths.
For good looking taxiline you should use the paint lines, at least between hold short and runway.

I am finding the same issue with the auto-pilot/copilot, it's not even going all the way to the hold short.
As *soon* as the aircraft gets on the runway (not even a runway type path, just the actual runway) it heads for the centre-line.
The problem(s) I have is
1)The taxiway enters halfway down the runway (so you have to backtrack)
2) The AI is rubbish at turns
3) in some cases this also causes it to ignore the'runway start' positions for when you choose to start on the runway, instead it uses where the AI copilot would take you to.

(to clarify, the reason I have a hold short on the runway is to try and get round 1) by having the hold short at the actual threshold rather than before entering the mid point of the runway)
 
This remains interesting, will start MSFS in a second and give this a try.

I think the end of my runway had a "runway" path part, but the airplanes that did land stopped and disappear in the middle of the runway.
 
Alright, something is landing!
let's see what it does

Edit: Unfortunately it disappeared again.
It comes to a rather fast stop instead of rolling through to the end.

that said, my runway path doesn't extend that far, so im going to check and extend it to that point

I turned on the debug menu and noticed something interesting.

On the right I have Runway 21,, on the left is the Runway 03.
So all parts on the right I called 21 for runway path, those on the left i called 03.

The debug menu shows a yellow path for those on the right, for 21.
But it seems to mark those on the left (to the 03 side) as taxiway (pink)

So i got the full runway covered as Runway 23 (shows as yellow) rather than splitting it into 2.

AI comes in on Rwy 23 and lands

But right after this screenshot it disappears.

You do hear the ATC say "turn next taxiway"

Yeah I have seen that, it's like if the 'RUNWAY' section is in a straight line from the 'TAXI' one it sometimes draws them both as 'TAXI'
 
Interesting development.

So it took almost 2 hours before something finally landed on my airport...
First the airplane landed, then switched some taxi lights on and slightly started rolling foward,, or actually maybe a bit too the left..

1600285599409.png



At this intersection it then went slightly to the right again and moved straight forward, yay!
1600285649978.png


At this point we got to the end of the runway where it needed to turn, perfect
1600285759635.png


Right after the hold point it came to a complete stop and called in Eindhoven Ground
1600285835055.png


Eindhoven Ground assigned this one to S3.
But at that point the airplane disappeared.

1600285854392.png




2 things I changed, the airplane landed at 03 but used the 23 runway taxipath.
Now I have to wait (tomorrow) and hopefully see one land at runway 23 and see if that one follows the same path as well instead of disappearing.
If that's the case, it means only 1 single "number" should be added.


But I've also changed the radius of my Ramps to 24,, this suddenly caused those bigger fake airplanes to spawn at my airport.
When this large one started taxiing,, i thought it might be related to at first not having a parking spot when it landed (as the radius was too small).

But after the hold point it still disappeared.
From what I can see, nothing should stop him from taxiing to S3

It looks like a similar issue to the runway, there was a taxi to the parking, but for some reason the debug menu didn't show the path.

movement is happening!
 
HI,
I cant seem to get the taxi nodes to attach to the runway line.
the runway line looks like its above the ground and moves when you pan around over it, and the ends of the taxi nodes wont attach to it.
is there a trick to that...???
Thanks
 
Usually when the three way arrow thing is in the air all you need to do is select it and move it in any horizontal direction and it snaps back to the ground.
