Adacalc 2.4

Adacalc is an accurate aeronautical calculator for windows.

Features:

-ICAO standard and non-standard atmosphere: high precision calculation of all atmosphere parameters (including standard ratio) up to a geometric altitude of 85 km
-Speed calculations: calculation of any speed (CAS, TAS, EAS, Mach, TAT) 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 and true altitude calculations (with humidity correction)
-En route and runway 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 or radials intersection using great circle and spheroidal equations
-Magnetic variation (from 2005 to 2015) at any world place calculated from IGRF-10/11 and WMM2005/2010 magnetic models (exact equations)
-Sunrise and sunset and twilight time values (UTC or local time) calculated from accurate NOAA algorithms.
-Unit conversions, Stall speed calculation
