It works OK, just a glitch: It's not internationally written. I livein Scandinavia and we use comma as decimal separator not period.First run showed an Exception Handling Error, fixed by changingdecimal separarator. Hope this will be fixed.LG

I took a quick look at it and like what I've seen so far. Unfortunately, I believe it can't be used with WideFS, but I hope that will eventually be addressed. Either way, seems to work well for me and I will definitely give it some use.KP

What a great idea! I can't wait to check this utility out after work.I looked at the docs and I just wanted to add that this utility actually uses some sort of conflict resolution algorthim, so the seperation parameters are enforced upon the potentially conflicting aircraft causing them to alter their behavior. This is great (I think). You can even tweak the parameters that determine whether a potential conflict exits. :-)

This begs the question .. if AI planes can be slewed, then why not just re-implement AI with slewing? Takeoffs, landings, cruise, taxiing, etc. That way, 3rd part ATC programs like Radar Contact could control AI traffic. Heck, someone could develop an AI control SDK which would basically be an AI slewing wrapper which fits over what already exists in FS2004.

Radar Contact in version 4 will have quite a bit of AI control. Look at their support forum here on AVSIM and do a search for the version 4 thread. Their programmer is working on seperation routines for air during approach and also to prevent the frequent occurance of AI taxiing onto the runway while you are in the last stage of final necessitating a go-around.I am a current 3.1 user with the latest release which recognizes AI by calling targets to you but in this version can't cvontrol them yet. Purchase includes FSUIPC registration for traffic features and FSUIPC provides AI control for developers now.

Excellent freeware program!Set it up at EGLL with 100% UT2004 Traffic adjusted the required separation (min 4 miles max 10) and it works a treat.Best to use in conjunction with the latest version of EditVoicePak which has the ability to speed the ATC communication up. This means everyone moves just that little bit quicker as well ;)Despite packed taxiways and landing aircraft every few minutes I only had one "go around" in 30 minutes. Cool :D(Note I had adjusted the UK2000 AFCAD file for EGLL to close 27R to landing traffic and to close 27L for takeoffs - this also speeds up the flow of traffic as in real life).Thanks to the author for a really useful utility!RegardsAdam

Hi,what about its impact on frames? did you see a significant drop or instability of frames?//Michael

Micheal, this program uses the win WXF file swapping technology which relies a lot on PC-3 platform released late 2004. If you do not have the xxxroftmal.cat3 on your Ponsky system (or perhaps your Panderora doesn't support it at all) then you can expect 4500% decrease in your frame rate.

Just checked to see if it would work with FS2002. It indicated that it 'connected' and no programs crashed, so I assume it works OK here too. I took a flight from KSAN to KLAS with traffic set at 81% and did not experience the usual 'go around' at KLAS.Cheers,Bob

It's just great when you just finished a 10 hours sleep, khmm I mean flight :) and a 737 run you over on the final AFTER you've been cleared to land. Now a question about this great new utility; can you see these slides? I mean would they break the illusion? Anyway I thank the author for sharing this tool with usQuantasluvr

Thanks for investigating! :-yellow1 However, this program requires the Microsoft.NET framework. You can download that from the main MS site :)

I have the .NET framework. But that is good information for anyone else who wants to try this on FS2002.Thanks,Bob

For me, it connects to FS2002, but I have no options to do anything with. When I select the "tab" - flight simulator - retrieve data, the program produces a program error. So with that, I don't think it works with FS2002..At least for me

I think you're right. After further checking, I 'm getting the same results. It looked like it was doing something, but the airport database for FS2004 is much bigger I guess, and causes the 'error in program' message.Oh well, it was worth a try.Thanks,Bob

Maybe tonight I'll try converting the airport database to FS2002 and see if I can get it going...

>Anyone using this yet? How is it?>>http://library.avsim.net/esearch.php?CatID...util&DLID=63288Yes, I think it's brilliant and has enabled me to eventually run 50% 'Traffic' on my modest system.I still find it hard to believe it. Microsoft should study this because this will solve so many 'FPS' problems. I don't know how 'Armando' did it but it's transformed my FS experience in FS9.If you read this Armando, thank you so much.All the best,Dave.'Three greens and soft landings'

I have been playing with it for about two hours.Great improvement over the default 'flocking' to the runway.If you are flying into a an airport after a long flight, you will be glad to know that your long flight will not be ruined by flocking and over taking aircraft. From the inflight point of view, this program delivers what it claims.If you are sitting on the ground, watching the traffic on approach, you will see some odd things, that you would not see from the cockpit on take off or approach. Or more correctly, you would not notice them. With all respect to the author, this was not what it was intended for. Still I observed from parked on the ground to learn how it worked.Here are the conditions I observed FS AITS under.Default weather, clear skies.Parked in the grass at KPHL between Runway 9R and 9L.I used to AFCAD to close Runway 9L for landing.(Using 9R for landing and 9L for takeoff.)Tuned the Radio for Tower, 9R Traffic. (120.425)I ran WideFS on a network machine.I opened NAV3.1 to watch the AI Traffic on the networked machine.I opened FS AITS Utility on the networked machine. (Works fine over WideFS.)I set the Minimum Distance to 4 miles, and the Desired Distance to 5 miles. I did tweak these up and down as I played.I Set the Airport NO MOVE zone to 5 miles, but later increased it to 7 miles.I set the time to 1830EST and spun my cessna around to the west to watch the show. Remember, this is a Runway Choking time of day at this airport. The results at say, KGSO were near perfect.Great improvement. I played with the settings to get less "traffic backing". I call it traffic backing and it is how FSAITS separates the traffic. It slews the traffic backwards. Once the simulation has been running for a minute or two and gets things sorted out, it is less noticeable than you think. I am a big fan of this program, and I list the odd things I observed as constructive feedback. I found that setting the Minimum Distance to 4 or 5 miles works better than the default. It lets them get a little closer a tthe busy airports. KPHL 9R has a lot of exit ramps, so the landing traffic departs the runway fairly quickly.I found that setting the desired separation distance to one mile greater than the minimum resulted in less visible slewing. Again I have only experimented with this for two hours, so I could be wrong. IF correcting a conflict, or slewing a plane backwards in a 'string of pearls', or planes stacked up on approach, a cascading effect could happen. This ultimately results in an AI track getting dropped because he can't reach his destination. I had an Air France Airbus 330 that kept getting shuffled backwards and I wanted to see it arrive. (Yes, I am a closet Virtual Plane Spotter.) The tower cleared him to land, and then he got shuffled backwards and his new slot created another conflict and he got shuffled back again. He did not acknowlege over the radio, and the tower started the "Air France 312? did you hear my last transmission??" I have never heard an AI asked that before. Eventually, the Airbus gave up and "fell to earth". I watched it plummet on Nav3.1 with a rapid descending altitude, and then nothing. (Kind gave me an uneasy feeling and I was glad I didn't become an ATC.)Another oddity, is that ILS traffic calls in from 20 miles out and gets the continue approach blessing, and then some VFR or pattern traffic at 4 miles out turns base right in front of him, and then on to final. The long approaching traffic gets slewed backwards, and possibly creates a cascade effect. This is not a problem with this program, but with FS2004 AI Traffic.The last observation I made, was that if small planes were on the KPHL RW8 approach, and the the 9R AI traffic came within the minimum distance, before both planes entered the NO MOVE zone around the airport, it would slew the traffic that was behind the other. I improved this situation by increasing the NO MOVE zone back out from 5 to 7 miles. This helped with the above paragraph as well, but did generate a few more go arounds, but that happens in real life. I did find that turning the traffic back from 100% just a little, seemed to improve the situation.The goal of this utility is not to elimenate go arounds completely, or to make a perfect plane spotting environment, it is to allow you to get into a busy airport with traffic on. I flew a flight from Baltimore to Philly in my UPS 727-100 (Flight1) and was guided in on vectors, lined up on localiser, and made a landing, with 100% traffic. That is a wonderful breakthrough. I got the frantic "Exit runway when able" twice, and when I did I looked to the left and there was a plane on short final. In fact there were a string of lights in the sky, just like I would expect. I didn't see any slewing while I was flying, or taxiing.This will change the face of Flight Simming, making it more real than "as real as it gets". Good job and thanks for your hard work.Sorry for the mistakes, I was in a hurry.Dennis Mitchell

Anyone tried this at Newark? Using UT set at 100% this is the worst airport in my experience with both a conga line along the taxiway and a mess in the air after letting the sim frun for about 10 minutes. Mike
