The Fiat G.46 was a military trainer developed in Italy shortly after World War II.

Design and development

The G.46 was a conventional, low-wing monoplane with tailwheel undercarriage, the main units of which retracted inwards. The pilot and instructor sat in tandem under a long canopy. The first prototype, powered by a 205 hp (153 kW) Alfa Romeo 115-Ibis engine, made its maiden flight on 25 June 1947.

Testing revealed excellent flying characteristics and suitability for aerobatics, and the type was ordered into production.

Apart from the 150 ordered by the Aeronautica Militare, 70 aircraft were exported, to Austria, Argentina and Syria.
