### Adding realism - Aero Calculator Software

Posted:

**Mon Jan 15, 2007 9:38 am**Do you like more realism in working out many calculations you make in Flight Sim?

http://perso.orange.fr/hsors/FS_Soft/adacalc.html

ICAO standard atmosphere: high precision calculation of all standard atmosphere parameters, including standard ratios, up to a geometric altitude of 65,000 ft

Speed calculations: calculation of any speed (CAS, TAS, EAS, Mach) at a given altitude and temperature, based on exact equations (compressibility equations)

Changeover level for any IAS-mach pair of values

Descent calculator: based on a 2/3-step precise numerical integration of constant Mach then constant IAS descent segments

Density altitude calculation (with humidity correction)

Enroute basic wind calculations

IFR turn parameters: bank, rate of turn and radius at constant or limited bank and calculation of turn anticipation angles

Tracks and distance between 2 points from great circle, WGS-84 spheroidal and loxodromic (rhumb line) models

Latitude and longitude calculations from track and distance using great circle and spheroidal equations

Radials intersection

Magnetic variation (from 2005 to 2010) at any world place calculated from IGRF-10 and WMM-2005 magnetic models (exact equations)

Sunrise and sunset UTC values (civil and official) calculated from accurate NOAA algorithms.

Might not be everyone's cuppa tea, but I like it!
