LET L-13 Blaník

The LET L‑13 Blaník is a two‑seat, high‑wing glider first flown in 1958 and produced by Czech manufacturer LET Aircraft Industries (originally Výzkumný a vývojový ústav Letová technika). Developed as a durable, easy‑to‑maintain trainer for aero‑clubs, the Blaník quickly became the standard primary glider in the Eastern Bloc and later found widespread use worldwide. Over 7,000 examples were built, many of them exported to Western Europe, North America and Asia, making it one of the most produced gliders of all time.

Key features include its all‑metal tubular fuselage, wooden wings with tapered planform, and a fixed monowheel landing gear. The aircraft’s simple control system, generous cockpit space, and forgiving stall characteristics enable student pilots to master basic flight maneuvers, winch launches, and even aerobatics. Its robust construction tolerates hard landings and repeated training cycles, while a relatively low stall speed (about 55 km/h) enhances safety.

The L‑13’s longevity has cemented its significance in aviation history; it introduced generations of pilots to soaring, contributed to the development of modern sailplane training curricula, and remains a nostalgic icon at airshows and flying clubs across the globe.
