The Aero 45 was a twin piston-engined civil utility aircraft produced in Czechoslovakia after World War II. It was the first product of the nation's post-war aviation industry and proved a great success, with many of the 590 produced exported.

Design and development

The development began 1946 and was accomplished by the technical designers Jiři Bouzek, Ondřej Nemec and František Vik. The prototype (identification: OK-BCA) flew for the first time on 21 July 1947, the second with the identification 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

Ae-45 prototypes were widely advertised abroad. In August 1949 Jan Anderle won 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 an Italian Ae-45 flew 3000 kilometers from South America to Dakar across southern Atlantic (as the first Czechoslovak-built aircraft), in 1981 Jon Svensen flew Ae-45S from Europe to the USA.

This type was used in Czechoslovakia and was exported to the People's Republic of China, East Germany, Hungary, Italy, Poland, Romania, Soviet Union and Switzerland. Hungary was a major customer, where the aircraft was known as the "Kócsag" (Hungarian: "Egret").
