If you have FS2002Pro, you can use Aircraft Editor (AE) that comes with Pro. You must be very careful when you use it, however. The editor uses templates for designing the aerodynamics. I found the templates a good starting point if you can find one that resembles your aircraft. If you are designing a jet, tail mounted engine aircraft, I would use the MD-83 *.air and aircraft.cfg file as a starting point vice the Twin Engine Commercial Jet template.AE adds new sections to the aircraft.cfg and *.air files based on data that is input into the various pages of AE. One interesting item I found using the MD-83 as a template was the MD-83 designer used a different reference datum position than the other templates. The designer used a more conventional reference datum position system used by aircraft manufacturers were the longitudinal measurement is from the nose of the aircraft (and in many cases a point in front of the nose) vice the visual model center. I noticed playing with this number confused AE. I changed to number from 77 to zero, saved the change, noted the differences. I then changed the number back to 77, saved the change, noted the differences. Just moving this number around caused AE to NOT return the effected variables to their original numbers when the position variable was restored to its original value. This is a big problem! Since I wanted to use the visual model center system, I had to make those changes and manually change the aircraft.cfg and *.air file effected values.Once I had the visual model center template, I could then use AE for making the necessary changes to the aircraft size, weight, etc. I did double check the values that were inputted to the aircraft.cfg and *.air files to be sure they seemed reasonable.I would also download the following for help in aerodynamics design:Aired152 - http://members.dsl-only.net/~eagle/FDEditor - http://www.flightsimdownloads.com/ - pretty much out of date.Aero Tutorials - http://www.flightsimdownloads.com/catalog/s372.htm#startingand any other aerodynamics files you can find on flightsimulation.
