Embraer E175
The scope-clause champion — America's favourite 76-seater · First flight 2003 · In service 2005
The E175 is a modest stretch of the E170 — 1.77 m longer, with the same wing and CF34-8E engines. It first flew in June 2003, and Air Canada put the first one into revenue service in July 2005.
Its real success came in the United States, where pilot contracts limit regional airlines to 76 seats and a maximum weight. The E175 fits those scope clauses exactly, so Republic, SkyWest, Envoy and Horizon fly it in large numbers for American Eagle, Delta Connection, United Express and Alaska. The 1,000th E-Jet, delivered in September 2013, was an E175 for Republic in American Eagle colours.
From 2014 the E175 gained wider, more angled winglets that stretch the span to 28.65 m, and Embraer says aircraft built after 2017 burn 6.4% less fuel than the original. Because the newer E175-E2 is too heavy for US scope rules, the original E175 is still in production, with around 840 delivered.
