• 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.

P3D v4 AI Traffic: 3 planes on the same position and no take-off

AI Traffic problem:
My plane comes on the runway and stops at its take-off position,
stands still and does not leave.
A second and third aircraft come and stop at exactly the same starting position.
So I have 3 aircraft at the same starting position and no aircraft is leaving. (see pic).
My hold shorts are placed correctly with the blocks facing the runway and not too far from the runway.
I don't see any incoming planes.
My planes are on the second runway and not on the main runway.
I do not know why.
Any help is welcome, thanks in advance.

1. You must use red hold short nodes, not yellow ones.
2. The HS nodes must be within 200 ft of the runway surface.
3. Blast pads (yellow chevrons) are NOT considered part of the runway and cannot be used to fulfill #2.
Hi Tom,
thanks for your response.
I found the (stupid) error.
I just created a Hold Short with the Ground Poly Editor without creating a Hold Short Taxi Point with ADE beforehand.
(I must not have been awake yet).
