Aero A.11
The Aero A.11 was a biplane light bomber and reconnaissance aircraft built in Czechoslovakia between the First and Second World Wars.
It formed the basis for many other Czechoslovakian military aircraft of the inter-war period.
Around 250 were built, with some remaining in service at the outbreak of World War II.
Designed by Antonin Husnik, it was a development of the Aero A.12.
A Hispano-Suiza 8Fb-powered version, the A.11H-s was built for the Finnish Air Force, the only foreign operator of the type.
The Finnish had eight aircraft of this type and used them between 1927-1939.
