In the field, computer programs are often used to take the FWI System starting values and weather inputs to provide FWI System indexes. The more computers are used, the less the user sees of all the inputs and underlying assumptions. However, for a complete understanding of the FWI System, users must know the assumptions of the FWI System and how the indexes are calculated. This understanding allows users to make better predictions.

The course is divided into four main sections. Each section is completed with a study test and the entire course is completed with a final test.

This CD-ROM based course provides the training and practice that will give learners an understanding of how FWI System indexes are derived and how this information can be used in real-life situations.

The course features a fully functioning stand alone FWI System calculator. It also includes a calculator for the Overwinter DC Adjustment and a Metric/Imperial Conversion Calculator.

Quick access to any part of the course is provided through an Index.

Content, mathematical, and scenario based interactions that give learners an opportunity to apply the theory. There is no scoring for Try It Out’s, but feedback on learner choices is provided.

To maintain learner interest, study tests are done using a game methodology. On the bottom of the screen, there are a number of lit matches. For each correct response a match will extinguish. For each incorrect response, a match will re-light.

To get test questions, learners pick from a selection of objective/content buttons that each contain a small test bank of questions. Successful completion of a study test is recorded in Christie Administrator.
