The E175 Enhanced (a step below the full re-engine) will improve fuel burn by 5%, says Tobias Caldas of Embraer at the Pacific Northwest Aerospace Alliance. This includes a redesign winglet and other fuselage/engine PIPs.
Enhancements include new avionics, interior improvements, maintenance cost reductions and noise reductions. Aerodynamic improvements will be forthcoming on the E-190/195. The E1`70 will have a 5% improvement, the E175 will have 5.5%, the E190 3.5% and the E195 4%.
Republic Airways is the launch customer for E-Jet “E” and will operate the plane for American Airlines’ Eagle unit. The order brings the current backlog for the E-Jet to about 150. (Aerospace analysts have been concerned for some time about the shrinking backlog, with production rates exceeding a 1:1 book-to-bill.)
Embraer continues to promote the E_Jet as a right-sizing mainline aircraft in the 90-125 seat segment, with 3,765 forecast as a requirement in the next 20 years in this segment.
The re-engined E-Jet includes a new wing and the Pratt & Whitney GTF engines. EMB is calling the revised airplane the E-Jet Second Generation (E-Jet SG). EMB to formally launch the program this year, with EIS in 2018. The models and size are being defined (though our market sourcing says there will be an eight passenger stretch). EMB says there will be “double digit” fuel burn improvment.
