Embraer ERJ 145 family
The Embraer ERJ 145 family is a series of twin-engine regional jets produced by Embraer, a Brazilian aerospace company. 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 ERJ 145 is the largest of the group. Each jet in the series is powered by two turbofan engines. The family's primary competition comes from the Bombardier CRJ regional jets.
==Development==
The ERJ-145 was designed for a perceived new market for regional jet aircraft, where the increased speed, comfort and passenger appeal would outweigh the inherent fuel economy of the turboprop aircraft which were in service and in development.〔(Resende, O.C.

Sci. & Eng. vol.26 no.4 Rio de Janeiro Oct./Dec. 2004 ) Retrieved 8 November 2015.〕 In order to reduce the development cost, it used the EMB120 nose and the same fuselage cross-section.〔
