Fligthsim relevant paramters

Hi Simmers!I'm working on a little plightplanning program and need som knowledge about calculation of miscelaneous flightsim relevant parameters. As examples I kan mention the following...(1)Calculation of "True Airspeed" based on input of speed (in knots) and altitude (in feets)(2)Calculation of "Descent Rate" in feets per minute (for 3 gr. glidescope) based on true airspeed (in knots)(3)Calculation of "Bank Angle" based aon true airspeed for props and jets.(4)Calculation of "True Airspeed" and "Mach-number" based on- Calibrated airspeed- MSL altitude- Altimeter Setting- Outside Air temp(5) plus other relevant parameters for instance those mentioned in the prg "Virtual E6-B".I would be glad for solutions, but also knowledge of websites or books, where these kinds of calculations (formulas) are mentioned and described. It would also be nice ti hear something about which parameters you as Fligtsimmers are using in your flyings.If my little program will be OK and placed on a website it will certainly be a freeware program.Kind RegardsLars
