The all-metal two-seater, type-certified in the standard aerobatic category, primarily intended for dual aerobatic training while also used for elementary glider training. It has the same cockpit as the L-23 Super Blanik with one piece canopy, the tail of an L-13, and shortened L-23 wings. The intended users of the L-13AC Blaník are clubs, commercial and military schools where instructors and other pilots are trained in mastering basic aerobatic maneuvers. The aim of L-13AC Blanik is to promote instruction in aerobatics, including recoveries from unusual glider attitudes. The availability of this kind of glider, similar to the original L-13 Blanik, the most widely used trainer in the world, makes it possible for instructors to refresh their aerobatic skills, and to pass the confidence gained on to their students.
