• 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.

FS9 > AI Traffic Engine Overload?

Hi everyone

I use World of AI for FS2004 AI Traffic and I've edit a few sets, such as adding a few more aircraft to the bgl or new flightplans etc, but, all of a sudden recently i've noticed that the amount of AI is decreasing.

For example, I do quite a bit of virtual spotting and I usually test at Manchester Airport (EGCC). I tested early morning and that progressed to the afternoon, during the early morning, there was (obviously) a lot of traffic on the apron and a lot inbound, then as it progressed a few hours, the amount of AI traffic dramatically decreased! So much so that the airport was nearly empty. I use AISmooth and it says 10 aircraft are been monitored and there are exactly 10 on the ground. It seems the AI Engine is either overloading or something is wrong.

I did test it at night (starting at about 20:30) and I had a very good flow of traffic past midnight with a minimum of 50 been monitored at all times.

I did reinstall FS9 and I copied my entire Aircraft folder back over (just all the AI folders and I then redid my aircraft merges) and also the BGLs into Scenery/World/Scenery folder. I have deleted a few extra BGLs to airlines I don't really need but I did it manually instead of through the World of AI installer.

Any ideas, cheers :)
 
There are folks using hundreds of WOAI packages without overload. I suspect you have less planes during the day because there are less flightplans in the file. One way to find out would be to decompile plans in question with ttools or AIFP .

I checked and the problem still occurs.

When I start up FS at an airport, the ground traffic and traffic within the 40m radius loads but then after about 5/10 minutes, the traffic in the air stops spawning so no NEW traffic appears. So after say 30 minutes I will end up with just the ground traffic to depart.

Not sure what the problem is! I checked all the WoAI with TTools but nothing suspicious :mad:
 
I can't help but think that you've got a bad traffic file somewhere. I'm not sure how you would find it except to add files one at a time for EGCC, and see what happens. Do it manually, without the installer

It could be a bad traffic file but they are all WoAI ones and they never caused this problem before. It doesn't just happen at EGCC, happens anywhere else.

I'm going to start from scratch, get rid of FS and everything related and install it all again and hope it works this time!
 
I think I would get new downloads of WOAI files, also.

Just a thought. Are you using WOAI because you don't like the default liveries, or want more realistic schedules, or both?

You can download real liveries for default aircraft. That's what I have done. Seems to be less hassle, though not real schedules. But I don't care about that.

WOAI works without problems in FS9 and in FSX, Bob (i.e. if you use AIFP to convert them to FSX traffic files and make the necessary changes to the cruise speed as per the AIFP manual instructions).
Pity you do not use them, they are really good.
So the problem must be elsewhere. For instance the FS9 traffic settings?
Remember, when you start FS, it spawns all the AI of the last 15 minutes or so (I do not recall exactly) so it is normal that you have less after a while. Now when your FS traffic slider is set to too low a percentage, many flightplans that have a higher percentage written into their flightplan will not show up.
Hence my question, jralston: at what percentage have you set your traffic slider (I do hope there is one in FS9 because I do not remember exactly)?
 
There is indeed a traffic slider in FS9, and ,jralston, that is a good point. Most modern computers can run traffic at or close to 100% in FS9.

Roby, I think I may have a WOAI plane or two in FSX, but I just don't want a lot of add ons. I'm not interested in real world schedules, so for both FS9 and FSX I have real world liveries for default planes and keep the default traffic file. I use AIFP to add traffic to my airports, and Edit voice pack so that ATC will call my airports and airline. I have added no scenery but a few airports I have created. I've added a few planes that I have done poor repaints of for my vitural airline. I don't even use any cfg tweaks. All this helps keep my costs down, and my FSX runs well.

I suspect it has been that way from the start and you are just now noticing.

This is a really terrible airport for AI spotting for anything more than a few minutes to a half-hour max in FS. The runway configurations and usage along with the turnaround times and the traffic load patterns will make the traffic appear to decrease the longer the airport runs.

AISmooth is going to keep many planes from landing at EGCC because of the runway configuration. They will not be reloaded at the gate as normally happens with AI aircraft which go missed three times.

Also many of the airline schedules will mean that after going missed a couple times at EGCC, the aircraft will be past its departure time from EGCC, so the AI engine will place the aircraft in the air departing EGCC, not at the airport on the ground.

EGSS has this problem with the RyanAir and EasyJet aircraft short turnaround times, but it impacts a lot of airports in the FS world when schedules have short turnaround times.
 
Ok, well I've done some fiddling and it started to work again well but it's dying back down!

AI is always set to 100% and I've tested Heathrow, it started well with about 35 aircraft in the air (checked on FSFlightKeeper) and within say 30mins-1hr, the amount in the air decreased to 15 constantly. There was very little traffic at cruise altitude going over and it was mainly just inbounds/outbounds to London airports.

As of now, it shows NOT a single inbound to LHR! Something must be wrong! I've tried a full uninstallation of FS and then redone everything which worked fine up until I copied back the original traffic BGLs I had worked on into scenery/world/scenery. All the Aircraft folders I did copy back though so it should be fine :S

I wasn't using AISmooth for this test, any ideas?
 
Hi,

I suggest you look for a small program called Traffic View Board (in AVSIM).
That way you can check if there really is no more AI around.
You could also decompile a traffic file with Ttools, check what airports are in the flightplan and at what time a flight is due to arrive or to leave. Then start FS and set your time at least a half an hour before that time. Set your speed to 4X and wait a couple of minutes. If your AI aircraft shows up, everything is normal, If it does not, well then there is something wrong somewhere.

I tried installing again and I noticed that the original WoAI packs work fine and the amount of traffic showing up and spawning seems reasonable for old packages, BUT, when I edited them through TTools and obtained new FPs from AVSIM, the new aircraft that I installed correctly and copied all the aircraft, flightplans and airports.txt files over and compiled again, the amount of traffic spawning dramatically decreases in the air!

Could it be something to do with Ttools? Maybe I need to reinstall that again, or could it be because we are in BST time zone at the moment and there is an hours difference from what they usually are?

Some images to demonstrate

Here is one when I refreshed the AI and gave it a minute, you see a decent amount shows up that are inbounds, outbounds and at cruising alts

Then around 5-10 minutes later you see no traffic usually at cruising alts and then just the departures from the local airports!

Is it because I am using Windows 7?
