What is primary glider?

A primary glider is a type of glider aircraft that is specifically designed for beginners or novice pilots who are learning the basics of gliding. It is typically a simple and lightweight aircraft, often constructed out of wood and fabric. The design usually features a high wing configuration, fixed landing gear, and a two-seater cockpit with dual controls that allow for instructor and student flight training.

The performance of a primary glider is generally limited, with a shorter wingspan and a glide ratio of 15:1 to 20:1. This means that for every 15 to 20 feet of forward motion, the glider will descend 1 foot vertically. The lower performance of primary gliders is intentional, as it provides a safer learning environment with reduced speeds and simplified controls.

Primary gliders are commonly used in glider training programs around the world. The training usually begins with ground instruction and progresses to short glides of a few hundred feet before advancing to longer flights. Primary gliders are also used for recreational purposes, such as soaring and cross-country flying.
