I had that problem, assign more parking spots See if that will work.

Did those. Nothing changed. Thanks anyway dyfly.
I'm not sure if there is a way to shorten the freez time in FS2002. ??? ???

Yeah I did that with the runways. It's just that the plane taxis off the runway and stops dead. Does not happen often. But sometimes it will stop halfway off the runway. Like at the stop node. I wonder if I could add a regular node and see what happens?

Any thought?

Actualy DYFLY it does not happen that often. I think I can live with it. I just wanted to see if anyone else has seen this occurance.

Hey how about aircraft that do a 180 on the runway to backtrack to the taxiway? I am getting lots of those. But I don't think it is possable to fix that. Has nyone seen this happen?

yep I had that to happen. Open up AFCAD and click on tools,click on fault finder and like planespotter said ,see if the taxi way to the runway are connect and the hold lines needs to be within 225 feet of the runway.
A hold-short node will not work if it is too far from the edge of the runway. That will result in ATC never giving you takeoff clearance and AI aircraft will stop at the hold-short node and get stuck there or when it lands it will turn around and look for a connected taxi exit.

. The maximum distance seems to be just over 230 feet, but it is best to keep it under 225 feet (68.6 m) to be safe. Note that the maximum distance is from the edge of the runway, not the center line.

The program can display 225 foot radius circles around all the hold-short nodes to show the maximum allowable distance. This can be enabled by checking the Show Hold Short Limits item under the View menu, or by pressing the ‘H’ key.

Note that hold short distance limits are only crucial where AI aircraft actually enter the active runway for takeoff and I have also seen for landing. AI enter a runway at the taxiway entrances closest to the ends of the runway. Hold-short nodes at other locations along the runway will not normally be used for AI entry.

This limit does not apply to ILS hold-short nodes, which are apparently not used by AI or ATC.

Another problem can occur when two or more aircraft line up at a hold-short node for departure, the aircraft at the front of the line may get clearance and proceed to take off, but the aircraft behind him may become stuck. This problem is more likely to occur with smaller aircraft. This can be prevented by placing a normal (blue) node or an ILS hold-short node just behind the hold short node. Some experimenting has shown this second node should be no more that 70 feet (21.3 m) behind the hold-short node to work with all sizes of aircraft.  As a rule of thumb, just place the nodes so they touch or overlap slightly.

Thanks DYFLY. I apreciate your help. I am also looking into fixing these problems. I have read everything in the AFCAD and PAI instructions and found little. I did add the extra node before the stop node. Seems to work. The planes don't seem to get "stuck" at the stop node now. Weird.

I am still trying to figure out the landing problem I mentioned. But nothing in AFCAD.

I just want to know if the landing problem is  a FS problem or a AFCAD problem. I'm beginning to think it is FS's problem and can't be fixed. But I will keep looking.

Thanks for all your help.

Here is the reply that I got on Flight Simmers AFCAD Discussions forum..

"It's inherent in the way Flight Simulator works. Not a lot can be done about it without detailed tweaking of each airport.

Basically you have to try and have a node just a little down the runway from where planes reach taxi speed. Then hopefully there is a taxiway exit further down the runway which is closer than the one behind.

FS AI aircraft will turn go to the closest node when they reach taxi speed. If it is behind them they make a u-turn. The aircraft turns based on the radius set in the model file - which usually means turning into the grass.

On some airports you can fix this with a lot of work. On some airports it cannot be fixed because normal procedure is to back taxi."

Ok here we go do this,at some airports they do not have taxi way. This is because #1 no room to put in a taxi way or #2 DOD no money going into the airport to put them in, cost to much money or not enough traffic to mess with. So, what you can do is build your on taxi way try this and this will work.
