Advanced Flight Simulator Data (AFSD)
Advanced Flight Simulator Data (AFSD) is a test program I developed with the help and feedback of aircraft designers in order to investigate FS internal functioning. The program simultaneously accesses and calculates sophisticated aerodynamical data  from Peter Dowson's FSUIPC interface, aircraft binary (.air) and configuration (.cfg) files.
AFSD works with FS2004, FSX and P3D. FSUIPC version 3.99 or higher is required for FS9 and FSUIPC version 4.942 or higher for FSX/P3D.  FSUIPC software is freely available on Peter Dowson site. FSUIPC registration is not required. Please read the AFSD release notes for more information.
Advanced Jet Performance Calculator (AJPC)
FS Control
Advanced Jet Performance Calculator (AJPC) is an utility designed for accurately calculating all performance tables and trip data (climb, cruise, descent or mission) of any jet aircraft (FS9/FSX/P3D) from model data (without any assumption). All calculations are based on exact equations and may greatly help model designers as well as pilots. No need to launch FS for using it !
FS Control provides advanced automation facilities to pilots: autodeparture, automatic ILS/LOC/Non precision approach tracking, autoland, automatic engine control (IAS, Mach and engine), autolean, holding and DME arc, navigation facilities (flight plan, direct to, track following) and some others. FS Control requires FSUIPC version 3.99 or higher for FS9 and FSUIPC version 4.942 or higher for FSX/P3D.
Navigation functions require an up to date worldwide or localized database (including ICAO airports, navaids and most intersections) that can be downloaded separately (latest WW database is included in zip package) or uploaded from within the program.
