Background
During the 1990s, the Brazilian aerospace manufacturer Embraer had introduced the ERJ family, its first jet-powered regional jet.As demand for the ERJ series proved strong even early on, the company decided that it could not rely on one family of aircraft alone and examined its options for producing a complementary regional jet, including designs that would be larger and more advanced than its preceding aircraft. During March 1997, Embraer made its first public disclosure that it was studying...
Intro flight
On 19 February 2002, the first prototype performed its maiden flight, marking the beginning of a multi-year flight test campaign involving a total of six prototypes. In May 2002, the aircraft was displayed to the public at the Regional Airline Association convention. During that same year, full-rate production of the E-Jet commenced; this activity was centred around a recently-completed factory built by Embraer at its São José dos Camposbase. After a positive response from the airline communi...
Production
In 2008, the 400th E-jet was delivered to Republic Airways in the United States. In September 2009, the 600th E-jet was delivered to LOT Polish Airlines.On 10 October 2012, Embraer delivered the 900th E-Jet to Kenya Airways, its 12th E-Jet. On 13 September 2013, the delivery of the 1,000th E-Jet, an E175 to Republic Airways for American Eagle, was marked by a ceremony held at the Embraer factory in São José dos Campos, with a special "1,000th E-Jet" decal above the cabin windows. On 6 Decembe...
The Embraer E-Jet family is composed of two main commercial families and a business jet variant. The smaller E170 and E175 make up the base model aircraft, while the E190 and E195 are stretched versions, being powered by different engines and furnished with larger wing, horizontal stabilizer and landing gear structures. From the onset, the E-Jet ha...
In early March 2004, the first E170 deliveries were made to LOT Polish Airlines, other customers to receive early deliveries were Alitalia and US Airways-subsidiary MidAtlantic Airways. On 17 March 2004, LOT operated the first commercial flight of an E-Jet, which flew from Warsaw to Vienna. Within four years, LOT was sufficiently pleased with the t...
E170
The E170 is the smallest aircraft in the E-Jet family and was the first to enter revenue service in March 2004. As of 2017, the E170 went out of production. The Embraer 170 typically seats around 72 passengers in a typical single class configuration, 66 in a dual class configuration, and up to 78 in a high-density configuration. The E170 directly competed with the Bombardier CRJ700 and loosely with the turboprop Bombardier Q400. The jet is powered with General Electric CF34-8E engines of 14,2...
E175
The E175 is a slightly stretched version of the E170 and first entered revenue service with launch customer Air Canada in July 2005. The Embraer 175 typically seats around 78 passengers in a typical single-class configuration, 76 in a dual-class configuration, and up to 88 in a high-density configuration. Like the E170, it is powered by General Electric CF34-8E engines of 14,200 pounds-force (62.28 kN) of thrust each. It competed with the Bombardier CRJ900 in the market segment previously occ...
E190 and E195
The E190/195 models are larger stretches of the E170/175 models fitted with a new, larger wing, a larger horizontal stabilizer, adding two emergency overwing exits, and a new engine. Both the Embraer 190 and Embraer 195 are fitted with two underwing-mounted General Electric CF34-10E turbofan engines, rated at 82.29 kN (18,500 lbf). The engines are equipped with full authority digital engine control (FADEC). The fully redundant, computerized management system continuously optimizes the engine...
As of April 2024[update], the three largest operators of the E-Jet family were SkyWest Airlines (241), Republic Airways (208), and Envoy Air (152), operating variably for Alaska Horizon, American Eagle, Delta Connection, and United Express.
