The Alfa Romeo 110 was an Italian four cylinder air-cooled inverted inline engine for aircraft use, mainly for trainers and light aircraft. The Alfa Romeo 110 was based on the de Havilland Gipsy Major, with approximately 500 units produced. Derivatives of the 110 include the -1, ter and Alfa Romeo 111[1] (possibly a mis identification of the 110-1).
