• 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.

AI aircraft stuck at push-back

Can anyone suggest why an AI aircraft should stick at push-back? It doesn't disappear, it just sits in the push-back state for ever :eek:

I have tried it at various airfields, all with the same result.

The aircraft in question is "AI VnW ALPHA A-3 Skywarrior" from http://vietnamwar.project.free.fr/
 
Hi Folks

George -
Don't know the answer,
but the following may give a clue.

In case you haven't done so already,
find the ATC tower and ground frequencies,
tune both your radios into each,
set both radios to active, sit and listen.

Give that it happens at multiple locations,
I'd also check whether the aircraft.cfg's front wheel turning-angle
is not set as overly restrictive, (its total angle, not x port and x stbd).

Could it be that the fact there are three skywarrior mdls and the aircraft cfg points to the A-3B instead of the A-3B_AI, lead to this behavior?
 
The file can be downloaded from Avsim. Use the extended search for filename vnw_ai.zip

Paul,

The steering angle is 42.54 :eek:

I have listened for an hour, and nothing happens, it sits at the push-back state.

Roby,

Yes, it is calling for the flyable model, but surely this will only affect the dislay.

re:ATC
Did it give permission ?

re:Aircraft.cfg
Quick test which might work
would be to move all the [fltsim.#] sections
to the bottom of the file.

If the aircraft no longer appears at all
then inspect the aircraft.cfg in a file editor
for inappropriate characters.

Also check for inappropriate values,
or commas instead of fullstops.

Hi,

Figured it out.
Problem is in the aircraft.cfg contact points section.
If you leave out the fourth wheel and the scrape points, your aircraft will start pushing back and continue on.
I still have to check if the scrape points really matter and because, when leaving out the fourth wheel (to the rear) the aircraft does not roll nicely, it will need some changes to the position of the other wheels.
 
Hi Folks

Roby -
Good catch. :D

Knew this issue sounded familiar, :o
having years ago
added twin front wheels to an AI AS332, (as per IRL).

Click to expand...

Great, works perfectly :D

Hmm, it rolls perfectly, it needs only for the wheels to be lowered by a few centimetres.
 
Tks, was nice to do. Just like making a puzzle or play cluedo.
Well, mine did not taxi nicely maybe because I changed the mdl?
Anyway, when making the folling corrections to the contact points, it does:
