Hi everybodyI made a little Delphi program to calculate True Airspeed, Rate of Descent and a few more data. I want the program to run along with my FS2004. I think it could be fun to be able to read the Airspeed and the altitude directly from the FS2004 via FSUIPC. My problem is that I do not how to do that. Does anybody know of some documentation I can read about how FSUIPC can made an add-on program read these data. Or even better a little codse example in Delphi (or i think VisualBasic is OK too allthough it's not me "language").Best RegardsLars

Lars,The FSUIPC SDK is available here:http://www.schiratti.com/dowson.htmlIt contains at least one example in Delphi.Doug

Thank's Doug. I'll be looking.Lars
