I am working on a project converting one of the planes (in our flight simulator) to FS9. All the visual is converted now. However, we have our own flight dynamics code for this aircraft which models more than a few things the FS engine doesn't handle. So, my question is. Is there a way to supply our own flight dynamic code for this plane in a form of a dll to FS9 just for this plane? If there is a way, is there any public information to go about doing this? I know this has been done many times for planes in CFS2 and CFS3, and at least once for FS9. Thnx.

You could presumably do the same thing with movement on all 3 axes.Doug Dawson

Thank you Doug. I will take a look to see if this method works for me. I was thinking about using the ABL mechanism; however, there are some problem with it. First, it only runs once a second. Second, it has no way to access an external dll (at least the document didn't state it can). BTW. How frequent can you overwrite those values through FSUIPC?

Gauges can update these values a minimum of 18 times per second, and alternatively, once each frame update, depending on how you do your coding. Not sure how a stand alone module would work, as I've never done that myselft... You might want to post a question on Pete's forum.Doug
