L-BUCD is the plane in which škpt. Vilém Stanovský along with mechanic František Šimek in 1926 made a promotional flight to Europe, North Africa and Asia Minor, covering a distance of 15,070 km and visiting 23 countries spending 91 hours and 52 minutes in the air. This replica (with the original Perun II engine) was made in Trenčín in 1981 for the Letecké Muzeum Kbely.

The Aero A.11 was a light bomber and reconnaissance aircraft first flown in 1924. The Aero company logo was based on the Czechoslovak roundel and this replica appears to be painted as a factory-owned aircraft, carrying a civil pre-1928 L-B registration. Apparently L-BUCD was c/n 17.
