The Embraer E-Jets line is composed of two main commercial families and a business jet variant. The smaller E170 and E175 make up the base model aircraft. The E190 and E195 are stretched versions, with different engines and larger wing, horizontal stabilizer and landing gear structures. The 170 and 175 share 95% commonality, as do the 190 and 195. The two families share near 89% commonality, with identical fuselage cross-sections and avionics, featuring the Honeywell Primus Epic Electronic flight instrument system (EFIS) suite. The E-jets also have winglets to improve efficiency.
