Indústria Aeronáutica Neiva is a subsidiary of Embraer which produces airplanes and aircraft components.
 Its main product is the Embraer EMB 202 Ipanema, the most employed agricultural aircraft in Brazil and the first alcohol-powered airplane.
 Neiva delivered more than 3,700 aircraft until early 2006.
Competition in the Regional jet market, contrary to the duopoly between Boeing and Airbus in the large jet airliner market, has several players from several countries and continents.
 This last decade, a fierce battle among well-established companies, Embraer E-Jet family and Bombardier CRJ700 series (the big two players), and emerging ones, Mitsubishi Regional Jet, Sukhoi Superjet 100, Comac ARJ21 and Antonov An-148 among them, has arisen in this lucrative billion dollar market.
The Embraer/FMA CBA 123 Vector (originally EMB 123 for Embraer and IA 70 for FMA) was a 1990 turboprop aircraft designed for regional flights, to carry up to 19 passengers.
 The program arose from a partnership between the Brazilian company Embraer and the Argentine FMA.
 The project was an advanced turboprop aircraft for its time, including advanced technology in avionics, aerodynamics, and propulsion.
The Embraer E-Jet family is a series of narrow-body medium-range twin-engine jet airliners, carrying 80 to 124 passengers commercially, manufactured by Brazilian aerospace conglomerate Embraer.
 Launched at the Paris Air Show in 1999, and entering production in 2002, the aircraft series has been a commercial success primarily for its safety and efficiency.
 The aircraft is used by mainline and regional airlines around the world.
 s of 30 2015 , there is a backlog of 263 firm orders for the E-Jets, 433 options and 1158 units delivered.
The Fairchild Dornier 428JET was a program undertaken by Fairchild Dornier to develop a 44-seat regional jet aircraft.
 The program was part of a broader attempt by the company to develop a family of regional jets, comprising the 328JET, 428JET, and the 728 series.
 This family of aircraft was designed to compete with the Bombardier CRJ and Embraer ERJ/Embraer E-Jets families.
 The aircraft was announced on May 19, 1998.
 It was cancelled in 2000.
The Embraer ERJ145 family is a series of twin-engine regional jets produced by Embraer, a Brazilian aerospace company.
 Aircraft in the series include the ERJ135 (37 passengers), ERJ140 (44 passengers), and ERJ145 (50 passengers), as well as the Legacy business jet and the R-99 family of military aircraft.
 Each jet in the series is powered by two turbofan engines.
 The family's primary competition comes from the Bombardier CRJ regional jets.
A scope clause is part of a contract between an airline and a pilot union.
 Generally, these clauses are used by the union of a major airline to limit the number and/or size of aircraft that airline may contract out to a Regional airline.
 The goal is to protect union jobs at the major airline from being outsourced to regional airlines operating larger aircraft.
 In 2016, the limit was at 76 seats and a 86,000 lb maximum takeoff weight, until 2019 at United Airlines and 2020 at Delta Air Lines and American Airlines, limiting the sales of the new Mitsubishi MRJ90 and Embraer 175-E2 to the smaller MRJ70 and current ERJ-175.
The Embraer Legacy 600 is a business jet derivative of the Embraer ERJ 145 family of commercial jet aircraft.
The Embraer EMB 202 Ipanema is a Brazilian agricultural aircraft used for aerial application, particularly crop dusting.
 It is produced by Indústria Aeronáutica Neiva, a subsidiary of Embraer located in Botucatu, Brazil.
 The latest version of this aircraft is the first ethanol-powered fixed-wing aircraft, which could give it an economical advantage over the gasoline version.
 The aircraft is widely employed in Brazil, having market share of about 80%, and the 1,000th delivery was completed on 15 March 2005.
 Besides aircraft, alcohol-conversion kits for gasoline-powered Ipanemas are also sold.
The Embraer E-Jet E2 family is a family of three narrow-body medium-range twin-engine jet airliners developed by Brazilian aerospace company Embraer, replacing the predecessor Embraer E-Jet family.
 The three variants share the same fuselage cross sections with different lengths and three different new wings, Pratt & Whitney PW1000G geared turbofans in two sizes, fly-by-wire controls with new avionics, and an updated cabin with 40% enlarged baggage bins.
 Announced improvements per seat are 16 to 24% lower fuel burn and 15–25% lower maintenance cost.
