AI disobedience

[msagner]

I'm experimenting with the AI traffic interface of FSUIPC, and have noticed that sometimes the AI planes will disobey their orders.

So far, I couldn't find out a pattern to this behaviour.

FSUIPC's return codes are being checked and signal that everything's OK, yet the planes will ignore some of their commands.

So far I didn't find a way to check on this other than changes in parameters (speed, heading) after a certain time.

Another phenomenon that I could observe sporadically was that AI planes on approach to a runway (status 'Landing') seem to get erased from the FSUIPC tables once they have been controlled by a third-party program for some time (two or three minutes).

All these phenomena are hard to reproduce since they do happen only from time to time.

PS: I'm using the latest FSUIPC version released March 4th, 2005, and there is no change in this respect to the previous version which I used to develop my piece of software.

Orders from whom?

Sorry, I'm not sure what you are talking about here. If you are trying to control AI aircraft with FS commands through the FSUIPC facility, you should be aware that most do nothing and many others are only of limited use.

For experimental purposes you might find it much easier to use the Traffic Toolbox from MS for this, sending selected aircraft controls via the dialogues it provides.

Are you saying that you can still see them on screen, or in the MS Traffic Toolbox, but not in FSUIPC's tables? FSUIPC only lists what it reads from FS. If FS erases aircraft -- as it will if they are "stuck" for longer than a certain time -- it will erase them. Without interference from outside this mostly hapens on taxiways when two meet head-on. One or both will be erased if no way out is found. I think the time allowed for a resolution was reduced from 10 or 15 minutes in FS2002 to around 5 minutes in FS2004, after general complaints about blocked taxiways.
