The ERJ 140 was designed with fewer seats in order to meet the needs of some major United States airlines, which have an agreement with the pilots' union as to the number of 50-seat aircraft that can be operated in their mixed fleets. The ERJ 135, with a service entry date of 1999, has 95% parts commonality with the ERJ 145, but is 11.7 feet (3.6 m) shorter.ĮRJ 145: The ERJ 145 seats 50 passengers, the ERJ 140 seats 44, and the ERJ 135 seats 37. The estimated cost of development of the ERJ 140 was US$45 million. At launch, Embraer estimated the cost of an ERJ 140 to be approximately US$15.2 million. The only significant changes are a shorter fuselage, a slightly de-rated engine and an increased range. Embraer delivered 892 units of all variants through 2006, and predicted that another 102 units would be delivered in the 2007-2016 time period.ĮRJ 140: The ERJ 140 is based on the ERJ 145 with 96% parts commonality and the same crew type rating. However, the aircraft has sold well thus overcoming the initial setbacks. The first design was intended to retain as much commonality as possible with the EMB 120. The key features of the production design included:

Though the aircraft went through many alterations before it was finalized, it did retain a few of the original influences of the EMB 120 such as the three abreast seating (2+1) configuration which was a similar configuration used for the Embraer/FMA CBA 123 “Vector” design which never reached production. The design evolved until late 1991, at which time it was frozen. This second design showed markedly better aerodynamic performance, but the combination of swept wings and wing-mounted engines required an unusually high, and therefore heavy undercarriage. The proposed modified design included a slightly (22.3°) swept wing with winglets, as well as engines mounted in underwing nacelles. 75% parts commonality with the EMB 120.īy 1990, Embraer engineers found that results from wind-tunnel testing were less than satisfactory, and began considering a significantly different design from the EMB 120.The ERJ 145 was launched at the Paris Airshow in 1989 as a stretched and turbofan-powered modification of the EMB 120 Brasilia. The family's primary competition comes from the Bombardier CRJ regional jets. Each jet in the series is powered by two turbofan engines. Family members include the ERJ 135 (37 passengers), ERJ 140 (44 passengers), and ERJ 145 (50 passengers), as well as the “Legacy” business jet and the R-99 family of military aircraft. The Embraer ERJ 145 family is a series of regional jets produced by Embraer, a Brazilian aerospace company. Variants: R-99 and P-99 Embraer Legacy 600.Developed from: Embraer EMB 120 Brasilia.Primary users: ExpressJet Airlines (As United Express) American Eagle Airlines.Twin-engine low-wing regional jet airliner, Brazil
