EMBRAER EMB-120 Brasilia


Encouraged by the successful penetration of the commuter airline market by the EMB-110 Bandeirante, EMBRAER initiated design studies for a completely new and pressurised twin-turboprop regional airliner in September 1979. Designated the EMBRAER EMB-120 Brasilia, the prototype flew for the first time on 27 July 1983 and certification was achieved by May 1985. Primary design objective was to carry a full 30-passenger payload for up to three 185km sectors without refuelling. The fuselage has an interior diameter of 2.28m and a cabin height of 1.76m, the aisle being offset by the two-and-one seating arrangement. In cargo configuration the Brasilia has a maximum available cabin volume of 31.1cu.m and is fitted with a cargo door in the starboard side of the rear fuselage.

Powered by advanced-technology Pratt & Whitney Canada PW118 turbo-props driving four-bladed Hamilton Standard 14RF-9 propellers, the engines can be ground-run without turning the propellers to facilitate speedier turn-rounds, thus obviating the need to shut down during loading or unloading. The starboard engine can act as an auxiliary power unit, to provide ground electrical power and cabin air-conditioning, but a conventional APU is optional. Composite materials equivalent to ten per cent of the aircraft's basic empty weight have been used in the construction of the Brasilia.

Deliveries began in June 1985 and by 1990 more than 500 orders and options had been recorded, for operators in three continents. In addition to airline use, the EMB-120 Brasilia is in service with the Forca Aerea Brasileira as the C-97 and VIP VC-97.

By early 1991 more than 200 had been delivered and the production rate was six per month.
The EMB 120ER model is the basis for Embraer’s regional jets.
