[edit] Design and development
After the success of the EMB-110 Bandeirante, Embraer began the development of their first transport category airliner in 1974. Originally called the Araguaia, the name was changed to Brasilia in 1979 at the official launching of the project. The design retained the T-tail and supercritical wing of the EMB-121 Xingu, but with the capacity for 30 seats. Originally designed to utilise the new 1500SHP Pratt & Whitney Canada PW115 Turboprop, this was later upgraded to the 1892 ESHP PW118.
The Brasilia attracted immediate interest from many regional airlines, particularly in the USA. The size, speed and ceiling allowed faster and more direct services around the US and Europe, comparared to similar aircraft. The first aircraft entered service with Atlantic Southeast Airlines in October 1985. The basic EMB-120RT was upgraded to the extended range (1,575 km) EMB-120 ER, with older aircraft retrofitted via a Service Bulletin.[1]
[edit] Operational history
Most of the EMB 120s were sold in the United States and other destinations in the Western Hemisphere. Some European airlines such as Régional in France, Atlant-Soyuz Airlines in Russia, DAT in Belgium, and DLT in Germany also purchased EMB-120s. Serial production ended in 2001. As of 2007, it is still available for one-off orders, as it shares much of the production equipment with the ERJ-145 family, which is still produced. The Angolan Air Force, for example, received a new EMB 120 in 2007.[2]
SkyWest Airlines currently operates the largest fleet of EMB 120s under the United Express and Delta Connection brand. Great Lakes Airlines currently operates six EMB 120s in its fleet.
