Aero A-11 HS

Aero A-11 on tšekkoslovakialainen kaksitasoinen, kaksipaikkainen ja yksimoottorinen tiedustelukone 1920-luvulta. Koneet suunnitteli ja valmisti Aero Tovarna Letadel, joka toimi Prahassa.
                           
Suomen ilmavoimat hankkivat kahdeksan Aero A-11HS-konetta korvaamaan Breguet-tiedustelukoneita vuonna 1927. 
Halpa kone ohitti valinnassa kalliimman ja paremman Fokker C.V. harjoitus-koneen.
                           
Koneiden tunnukset olivat AE-41 - 48. Konetyyppi oli käytössä vuoteen 1939, lopussa koulukoneena. Ensimmäinen käyttäjä oli Maalentoeskaaderi Utissa.

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 a large number of 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 (despite what the numbering of the designs might suggest). 
                       
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 Finns had eight aircraft of this type and used them between 1927-39.
