I can see taking off aircraft normally, but i never see any landing a/c in fs 2k4, i use PAI Addons and took my default traffic out (American Pacific etc. my traffic is at 100%, whats wrong?

How long do you wait?As I understand it, when you move to an airport, all the aircraft scheduled to take off for up to 5 minutes BEFORE you arrived start taxiing out to take-off.Aircraft scheduled to land first have to descend from their cruising altitude where FS9 puts them before they come in to land.So for the first 5 to 10 minutes you get all take-offs and no landings. If you wait long enough, you should see aircraft landing.It's a good idea to sit around at your gate setting your nav radios and autopilot settings etc etc before you taxi out - hopefully by the time you get out to the runway behind a queue of departing aircraft, you'll start to see the first arrivals!

still dont see arrivals, any ideas

if you are seeing take-offs with default flightplans, must be a landing eventuallytry going to a big airport of your choicemaybe take the default Cessna, dont report to ATC and taxi out to the end of the active and wait around a bit

I mean park on the grass adjacent to the active, switch off the engine and wait

If you go to a large airport you have a better chance of seeing arrivals. Also make sure you have a good AFCAD file for gates, parking etc. AI will not land if there are no gates to park. Or they may land and disappear off the runway. Most default MS airports do not have sufficient parking spots/gates to handle third party AI addons

Even so, the AI will still land, but will dissapear shortly after taxiing from the runway.I use the Project AI system too...have all the commercials, cargo and military installed (updated yesterday to catch a couple of new August arrivals!), and a few other PAI models for military such as KC-135's and AWACS E3's, and my airports and military fields are full of AI taking off and landing, as expected. As posted above though, it may take a while for landings to start as the AI have to actualy be within an aproximate 40 mile radius of YOU before Flight Sim activates them, so an inbound flight, even though it's 'virtualy' taking place due to the flight plan, will only become a 'physical' reality within 40 miles, and then visible to you at 10 miles.To test this, I would suggest that you have your AI set to 100%, taxi from one of the gates at a large airport such as London Heathrow, and join the queue of taxiing AI to your departure runway. If you set a mid-morning time (11:00) then you are guaranteed to see at least two maybe three inbound AI aircraft as you wait in line to depart. Sometimes I've waited for 35 mins at least, and can see, and hear via ATC at least 4 AI on their way in to land.Just be patient....you'll see them...Project AI aircraft work perfectly well, as does Flight Sim...unless you got a wierd corrupted installation (MOST unlikely!!).

I have three suggestions: 1. Are you familiar with the CTRL+W command which opens a window in which, by continually hitting CTRL+W will cycle through all the planes in the 40 mile or so vicinity? If you do this you might see a plane on approach. You can then watch it all the way to landing.2. If you have MSFS' 'Traffic Toolbox' installed, you can see at a glance which aircraft are doing what and view any one.3. If you decompile the traffic bgl with 'Traffic Tools' you can read the flight plans and see what time a particular flight is due to land. Line your plane up close to the runway several minutes before and wait!Using anyone of these will confirm that your AI traffic is working as it should.
