AiToolkit - Calcs provides a comprehensive set of tools to allow calculation of the majority of common accident investigation calculations performed. 

AiToolkit - Calcs includes calculations used in the UK City & Guilds - Forensic Road Collision Investigation syllabus, taught within UK Accident Investigation training centres along with a number of other commonly used formula.

AiToolkit - Calcs is provided with an easy to use Windows interface and has extensive fully detailed help available at all times including the relevant formulas used within the calculations.

 

AiToolkit - Calcs uses a MDI (Multiple Document Interface) interface allowing multiple calculations screens to be simultaneously viewed allowing easy follow on calculations.

      

Fully detailed hard copy printouts for all calculations are provided with the appropriate formulae. 

AiToolkit - Calcs includes a user customisable toolbar allowing users to swap instantly to their CAD and word processing packages.  Also provided is a switchable button bar allowing instant access to the required calculations.

Detailed on line help is provided for all calculations employed.(now extensively revised and improved)
