Afcad problem...

I've noticed that when my aircraft are landing they exit the runway and dissapear once they hit the taxi way. they have plenty of parking spaces and all my taxiways are designated. so what could the problem be? here is a picture of where it is happening.

One reason that I have found that happen is that there isn't a normal node near enough to exit of the runway, we had this same problem in the beta of the Spanish Harrier pack.

Try adding a node just after the hold short node, as you exit a runway or just before the hold short if you were heading for the runway. Basically make sure that the node is between the runway and the point that it disappears.

that was indeed the problem. Never had that happen before. thank you Steve!

I dont remember if afcad allows this as it's been a long time since I used the original afcad tool, but in AFX you can view the hold short radii via the View menu.

The hold short radii must intersect part of the runway to be considered "valid" for AI operations. I think it was Reggie Fields, while explaining the FSX ATC implementation on another forum, who said that that meant the runway surface, not the black line. Also, overrun areas of the runway don't count but displaced sections of the runway do.

While this discussion/explanation was about FSX, I'm pretty sure that it is relevant to your problem. Couldn't hurt to take a look at this.

He also said that adding an additional node between the hold short node and the runway will not affect the "intersection" issue. What it will relate to is the point at which AI aircraft switch from ATC approach/GCI to ATC ground control. This is why you sometimes see ai aircraft stop at between runways and taxiways where no hold short exists.

Food for thought.

good info, all i did was place a node between the hold short and the taxi link, the aircraft still stopped but kept going right after.
thanks for the info guys.

Although you said you had enough parking, i suggest checking the coding and parking types, and most definately the radius of the parking and the aircraft themselves and make sure they all work together, and if nothing else, check to make sure you dont have any broken taxiway links....If the aircraft cannot actually get to the parking, they will dissapear...
