About the Course

Prerequisites: Glider Familiarization
Approximate time to complete: 2 hours, 15 minutes

In this course, you’ll learn about the forces that act on a glider, and how these forces are created. You’ll also learn about how these forces affect the stability of the glider, and how the different airspeed limits are related to these forces.

It is important that you know this information so that you can understand how the glider will react under different conditions, and so that you understand why you must respect the airspeed, loading, and center of gravity limits specified by the manufacturer.

  • Great Visuals!

    The videos and other visuals help the student truly understand and quickly develop an intuition for what really happens when wings meet the air.
