Simple Flying[3]: 'The prototype aircraft first flew on July 27, 1983'; Wikipedia[2], Airfleets and Aviacionline agree. Embraer's[1] own history page and Aeropedia[4] give 29 July 1983, the day of the official presentation and christening, so the day is disputed by two days.Embraer's pressurised 30-seat EMB 120 Brasilia turboprop prototype PT-ZBA flew for the first time in July 1983 at São José dos Campos, the airliner that opened the US commuter market to Embraer.
