The Embraer EMB 312 Tucano is a low-wing, tandem-seat, single-turboprop, basic trainer and counter-insurgency aircraft that was developed in Brazil. The Brazilian Air Force sponsored the EMB-312 project at the end of 1978. Design and development work began in 1979 on a low-cost, relatively simple, new basic trainer with innovative features which eventually became the international standard for basic training aircraft. The prototype first flew in 1980, and initial production units were delivered in 1983.

A trainer is a class of aircraft designed specifically to facilitate flight training of pilots and aircrews. The use of a dedicated trainer aircraft with additional safety features—such as tandem flight controls, forgiving flight characteristics and a simplified cockpit arrangement—allows pilots-in-training to safely advance their skills in a more forgiving aircraft.
