The airspeed indicator, the variometer, the yaw string, and the compass are your primary tools for tracking the glider’s position and movement through the air. Because of their crucial role, it is important that you understand how these instruments work, and how you should interpret the information they provide.

In addition, many gliders have additional instruments and systems. These can include G-meters, radios, transponders, GPS, and supplemental oxygen systems.

In this course you will learn about the instruments and systems that you may encounter in a glider, and how those systems work.
