Hi Peter (beroun),

It took me a while to get somewhere with this problem, but I think I may know what the problem was. That was causing many AI Aircraft to Disappear, on Approach to Amsterdam Schipol Airport.

One thing I was doing, was trying to change arrival and departure times for certain Flightplans, from the "Flight 1" Ultimate Traffic 1 Traffic.bgl File.

To do this I was opening that File up, in a version of the Program AI Flightplanner. The program was finding many errors, with the File including Flight Altitude missing, Aircraft unable to return within repeat period errors and many others.

I am thinking that may be due to the fact, that AI Flightplanner was unable to read this Traffic.bgl File properly.

Possibly because it is put together, in a different way to other AI Traffic Files ? Also as with other AI Aircraft Flightplans I have compiled, using the AI Flightplanner program, it removes the @ Symbol from Flightplans, when you save the Flightplan Files, using that Program.

I hadn't noticed that until very recently. So when I compiled the Traffic.bgl File, with that program, the @ Symbol which was present in the Flightplans, with the original Ultimate Traffic 1 compiled Traffic File, had been removed from All those Flightplans.

So maybe the famous "37 minute problem" was coming into play here ? I have had other AI Aircraft disappearing from FS2004, when I have compiled other Traffic Files, using AI Flightplanner. So I am thinking it was the same problem in those cases ?

When I use an Ultimate Traffic 1 Compiled Traffic.bgl in FS2004, not edited by me, the same AI Aircraft seldom disappear.

I now compile all my other AI Traffic Files, using the TTools Program. using the @ Symbol in my Flightplans.txt File and changing all the Speeds of the AI Aircraft, to 200 knots in the Aircraft.txt File, as it is strongly advised you do. And I am having far fewer disappearances now, than I was before.

I do have a problem though, with the AI Separation Program. I use it in conjunction with the AI Smooth V 1.11 Program, using the recommended settings by Dave Sheffield, when using them together.

I find that many AI Aircraft (conflicts) ?, that should be slewed back to start the approach to EHAM Airport again, simply disappear completely. And don't start the approach again, like the AI Separation Program, is supposed to do for the AI Aircraft.

Do you have have any ideas, of what could cause that problem Peter ?

Regards Eddie

Hi Eddie,

I would not use AI Smooth and AI Separation together when running FS2004. Perhaps that is causing your problem. Try only one at a time or none.

Many thanks Peter, for your suggestion.

It also happens, when I use AI Separation on it's own. With the settings 6,8,5,20,8,35

The Flightplan with the AI Aircraft in question, had the @ Symbol. I had a Traffic File, from the Optimised Speeds Version Flightplans, of the same Package, made using AI Flightplanner.

Without the @ Symbol and the AI Aircraft in question still disappears and doesn't start the approach again. I see it go backwards, i.e. being slewed backwards by the AI Separation Program. But it vanishes completely, rather than start the approach again, to Schipol Airport. So fixed and non fixed arrival times doesn't appear to be the issue.

Does anyone have any ideas, what might be causing this problem ? I am unsure myself, this happens with other AI Aircraft too, not just this one.

Regards Eddie

Hi Eddie,
AI Separation and AI Smooth programs are primarily to avoid congestion on approaches. As you know FS is vulnerable in this and while flying approaches you often get close to AI traffic, sometimes virtually surrounded by it and have to go around while sitting on someone's tail (sometimes blending into another aircraft or crashing). Obviously not realistic but this is the way FS works. Yes it is a flaw but reducing the AI traffic % usually helps.
Now to your question about disappearance. And this is only my assumption. AI Separation and AI Smooth hold aircraft back from approach and from what I can see it holds in the holding pattern in circles. At least this is what I noticed when watching the AI traffic in Traffic Tool board. I am suspecting that the holding pattern is similar as if the AI aircraft would stand still on the deck waiting for approach or for other AI to pass by. Now what happens when the AI does not move. It disappears (times out). Probably the same happens when AI is held by another program holding in the air.
As mentioned above this is only my assumption on bases of what I have seen.
Cheers

Hi Peter (beroun),

I think you are right on the money, with your observation. And many thanks, for responding to my, last post.
Does the TrafficViewboard Freeware AI viewing program. Affect AI Aircraft more than other AI Viewing programs ?

I use the excellent freeware Traffictoolbox, and have recently purchased the payware program AIRound v1.0. And I like them both, as I do TrafficViewBoard. I have read on forum posts, that TrafficViewBoard, can affect AI Aircraft. Could disappearing AI Aircraft, be caused by that program ? I mean simply looking at the menu, and looking at information about AI Aircraft, rather than viewing them directly on the ground or in flight ? Eddie

Hi,
You might be right about Traffic Tool (view) board acting up. I use it only randomly when I am tired of flying and have no experience with other viewing programs.
But yes it did happened few times that looking at aircraft in TTB they sometimes disappear and the screen seems to plunge to the ground. I really do not pay too much
attention to it. The flying seems to be my priority.
Cheers
