The two-seat all-metal L 13 AC Blanik is an improved version of the L 13 Blanik with excellent aerobatic characteristics. It has been designed for dual elementary and aerobatic glider training. The wing tip extensions improve its thermal and cross-country flight characteristics even further.

The aim of the L13AC Blanik is to promote instruction in aerobatics, including recoveries from unusual glider attitudes. The availability of this kind of glider, similar to the original 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. The advent of the L13AC Blanik heralds more participation in glider aerobatics, and brings a boost to the sport of soaring.

The L 13 AC Blanik is manufactured according to BCAR requirements and is Type Certified in the Czech Republic and in the USA.
