based on US 1976 model] Adds an additional data set to atmosphere calculations (g, dynamic & kinematic viscosities, thermal conductivity) Corrects a bug (runtime error) observed in atmosphere calculations when max accepted altitude value was entered Few other minor changes Version 4.00 (19-Aug-2018) -------------------------- Adacalc 4.xx is now a portable application only [In case you used Adacalc 3.xx in its installable version, first uninstall it, if you used 3.xx portable application just delete and replace Adacalc folder-Note: Version 4.xx cannot be retrieved by updating from version 3.xx] Old waypoint/nav database format not accepted nor converted anymore (use available new format instead) Includes default worldwide database (EHNavDB_WW.dat) in application folder that can be updated either automatically or on demand [Note: custom valid databases in new format can still be used] Changed all downloads (version check, auto-update, database version check and retrieval, some other Internet downloads) using an asynchronous process from main menu Adds an auto-update option (once a day as default) Allows runing 2 instances of the program at the same time Coordinates format change now available in all modules using shortcuts (Ctrl-D for decimal format, Ctrl-N for degrees/minutes, Ctrl-S for degrees/minutes/seconds) Accepts more valid airport ICAO codes in weather

changes Version 3.52 (26-Dec-2017) -------------------------- Improves OS identification Improves window composition Removes window position initialization option (due to a some problems on a few

2.00 removed Version 3.50 (5-Oct-2017) ------------------------- Waypoint database format change for extended precision (1 centisecond) [IMPORTANT NOTE: Any previous databases (old format) can still be used (but only with their current precision that is 1 decisecond) However, for those using default databases (HNavDB_WW.dat or HNavDB_LF.dat), new versions are available as EHNavDB_WW.dat and EHNavDB_LF.dat These new versions will be automatically retrieved when updating In case you use a "personal" database you would like to convert, just mail me] Some changes in coordinates and track inputs (max precision) Adds equirectangular flat earth projection calculation (acceptable approximations for short distances) Refine mean earth radius (refered as IUGG Geodetic reference system 1980 rather than FAI) Corrects some incorrect labels Adds a warning when loading an old format database (can be disabled in program options) Many minor changes in data input and recalculation events Version 3.00 (25-Sep-2017) -------------------------- Adds several published model algorithms for calculating track/distance between 2 points (indirect calculations) and associated direct calculations

Aviation database default links updated Some code optimization and other minor changes Hervé Sors hsors@hotmail.com http://www.aero.sors.fr/adacalc.html
