Introduces the various aspects of present and future Air Traffic Control systems. Descriptions of the present system: systems-analysis approach to problems of capacity and safety; surveillance, including NAS and ARTS; navigation subsystem technology; aircraft guidance and control; communications; collision avoidance systems; sequencing and spacing in terminal areas; future directions and development; critical discussion of past proposals and of probable future problem areas.

In this math activity, learners are challenged to create aluminum foil boats that will hold plastic bears until the boats sink. The lesson serves as a fun, hands-on way to collect data. Data from two attempts is collected and used to make two class box-and-whisker plots with some surprising results. This lesson guide includes questions for learners, assessment options, extensions, and reflection questions.

  Purpose:This tool guides teams in evaluating and evidenced-based improvement strategies (EBIS)prior to implementation.Description:As a tool to evaluate readiness for implementation, this resource is designed to systematically lead teams in a thorough examination of the EBIS before it’s implemented in a sc During this study, the team answers questions about their current evidence for the “Program Indicators” of Evidence, Supports, and Usability as well as the “ Implementing Site Indicators” of Need, Fit and Capacity.
