i slewed up my cessna to observe the PAI traffic and during like the first 2 mins a AA taxies away from the int, terminal. then after a min i look back and all of a sudden there is a UAL i think 767 in its place, i did not see it land or taxi. then i barley missed a continental land and i look to see it taxi to the gate and its no wher to be seen. then a UAL lands and im closely watching it and very shortly after ATC says turn next taxi(maybe 5 seconds after) the UAL disapeers. whats up with that? it happend at KORDadamYou cant truley understand flying until you have actually tasted and felt it.

Both the issues you describe (the UAL 767 popping up and the other one dissapearing) are related to lack of parking spaces. First of, since it seems the airport had all gates full, when an aircraft leaves the gate it makes a gate available for another one.This is why you see it "pop" up at the gate its a planned departure in the flightplans so it has been waiting till a gate became available.The other incident is also becos there is no gates available. It will simply dissapear and not wait around for a gate to become free.Am a little surprised for it to happen at a huge airport like KORD though lol :DAll these issues will naturally go away once AFCAD 2004 becomes available sometime this month :)

That will often happen if there are not enough gates for the aircraft, if they can't park they disappear.Regards,Van LatendresseYeoDesigns/AFG GroupPanel/FDE Designer

Hi there:I had this cool experience with a test carrier AFCAD file I made for FS2002 a while back. I could only place four parking spots on the carrier (CVN-74) but set up about ten flightplans for different jets. After the first pack of four had left the deck in rapid succession, the next four appeared out of the blue (perhaps from below deck?). Anyway, the first reply to your question was bang-on and it's generally an undesired occurrence that you can minimize by reducing the number of flight plans or decreasing the % density slider for AI aircraft.Cheers, Holger

Mine was better (or worse, depending on how you see it).I took off from Miami Int'l with my AA777, checking the radar while I was climbing. On my way up I found 2 Delta planes flying in circles, climbing at 7000 ft/min, the next moment descending at 8,000, then ascending at 7500, and so on and on.Also my flight was a real life one, and a AA777 took off seconds before I did with the same destination I had. I said W0W, PAI made its flight plans like in real life. I flew with the plane together (just a few miles ahead of it) for 1000 miles, and suddenly disappeared, bermuda triangle?, or just went down and I didn't notice?A shame I didn't have a FS newspaper to find out what happened to that plane.Leo

It's not the PAI plane, it's the way the sim is made. Consider facts before slamming next time :-)http://fsgateway.com/frank/fs9paibeta.jpg

As Frank said is the inner workings of FS, if you follow an AI, you will notice that after a several hundred of miles depending on the heading the AI will simply vanish in the air, this is because the AIs only fly on the assigned Cell that they take off or land.Once they get close to the boundary of that specific cell they are gone...It has it advantages, as it would be very hard for todays computers to keep up with world wide air movements.
