Essential components of a new scenario-based air traffic control (ATC) training platform whose effectiveness is being analyzed are outlined with respect to its use in the decision-making skills of trainees when confronted with emergency situations. The custom designed platform allows the trainee to interact with the program such that the 10-minute ramification of a proposed aircraft redirection can be explored visually before a decision is made. Actual previous extreme weather incidences are used. Testing of the platform is ongoing with ATC students from Kent State University. Data from subjective pre- and postquestionnaires as well as objective decision parameters are currently being taken.
