Adacalc Version 2.42 by Hervé Sors

Hervé Sors has updated Adacalc to version 2.42. More information and download on the Adacalc Website.


Adacalc is an accurate aeronautical calculator including the following modules:

-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 altitude calculation (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
-Holding pattern data (with wind corrections) and holding entry calculator
-Tiny mathematical calculator
-Aviation weather data (from NOAA) and customizable aviation data links (with provided default set)
