Design and development[edit] The development began 1946 and was accomplished by the technical designers Jiři Bouzek, Ondřej Němec and František Vik. The design bears a superficial resemblance, viewed nose-on, to the German Siebel Si-204 which, among other German aircraft like the Bf 109, were produced in Czechoslovakia
while under German occupation. The prototype (registered OK-BCA) flew for the first time on 21 July 1947, the second, registered OK-CDA, one year later. Flight testing ran without incidents and the type was released for series production in 1948. The model number of "45" was not a continuation of Aero's pre-war numeration scheme, but a reference to the 4/5 seats in the aircraft. Operational history[edit] Ae-45 prototypes were widely advertised abroad. In August 1949 Jan Anderle won the Norton Griffiths Race in Great Britain (Ae-45 registration OK-DCL). They also set several international records. As a result, apart from Eastern Bloc countries, the plane was also bought by Italy
and Switzerland. On 10–11 August 1958 Dr. Pier Paolo Brielli flew an Italian Ae-45 3000 kilometers from South America to Dakar
across the southern Atlantic (as the first Czechoslovak-built aircraft). In 1981 Jon Svensen flew Ae-45S from Europe to the USA.[1] This type was used in Czechoslovakia
and was exported to the People's Republic of China, East Germany, France, Hungary, Italy, Poland, Romania, Soviet Union
Soviet Union
and Switzerland. Hungary
was a major customer, where the aircraft was known as the Kócsag (Hungarian: "Egret"). Variants[edit]
