In this small-group activity, learners assume the roles of pilots, air traffic controllers, and NASA scientists to solve five Air Traffic Control (ATC) problems. Learners examine different distance-rate-time air traffic scenarios that an air traffic controller might encounter. Each Air Traffic Control Problem features a Student Workbook containing an air traffic control experiment, paper-and-pencil calculations to support the experiment, and a student analysis of the experiment and calculations. The Workbook can be supplemented with optional pre- and post-tests. The FlyBy MathTM curriculum materials also include video clips to introduce learners to the nation’s air traffic control system. Each Air Traffic Control Problem is accompanied by an Educator Guide with a full set of answers and solutions, as well as suggestions for implementing the specific airspace scenario.
