Full-featured flight reporting software for virtual airlines

BACKGROUND
FSACARS automates flight reporting and tracks flights using a simple, easy-to-use client that accurately records dozens of different flight parameters, and sends the data to your server. You and your team can manage this data however you like. I started development of fsAcars more than 20 years ago for my own use, and for others. Since then, tens of thousands of flights have been successfully logged.

FLIGHT REPORTING DATA
More than 70 data points, including landing performance (VS, touchdown speed, landing distance), takeoff and landing weather: VFR, MVFR, IFR, LIFR; realism auditing - pause, slew, overspeed, crash, refuel, and many more.

Recent Updates

January 29, 2021	In 2020 development of a new major release candidate started. Development continues in 2021 with a planned release sometime in the first quarter. Version 3 includes a new interface, many new features and improvements - things that you will love!
August 27, 2020	Confirmed full functionality with Microsoft Flight Simulator 2020 using FSUIPC 7
June 10, 2020 (v 2.996)	1. Moved posrep connection error messages to acars 2. Reset position reporting interval
June 8, 2020 (v 2.995)	1. Fixed a bug in 2.992+ that was incorrectly reporting the vertical landing rate. 2. Added new variable: landingG = gravitational force at landing 3. Deprecated landingFPS to landingFPM (ref v2.9)
June 6, 2020 (v 2.994)	Updated SSL/TLS secure channel protocol
June 5, 2020 (v 2.993)	Improved network interaction Improved vertical landing speed (fixed bounced landings) URL encoding of password supports non-alphanumerics
