advanced range (AR) models, the latter being intended for long routes with limited passenger numbers. The smaller members of the E-Jet family are powered by the General Electric CF34-8E turbofan engine, each capable of generating up to of thrust, while the stretched aircraft are outfitted with the more powerful General Electric CF34-10E, capable of producing a maximum of thrust. These engines have been designed to minimise noise and emission outputs, exceeding the requirements established by the International Civil Aviation Organization; the relatively low acoustic signature has enabled the E-Jet to be operated from airports that have imposed strict noise restrictions, such as London City Airport. The type is also equipped with winglets that reduce fuel burn and thereby improve operational efficiency. The E-Jet family is equipped with advanced avionics, which includes a fly-by-wire flight control system. The flight deck is furnished with the Honeywell Primus Epic Electronic flight instrument system (EFIS) suite and has been designed to facilitate a common type rating, enabling flight crews to be readily moved between different members of the family without the need for any retraining/recertifying and providing greater flexibility to operators. Early operations of the E-Jet were frequently troubled by avionics issues; by September 2008, Honeywell had issued software updates that sought to rectify the encountered issues. The main cabin is configured with four-abreast seating (2+2) as standard, and features a "double-bubble" design that Embraer has purpose-developed for its commercial passenger jets to provide stand-up headroom. The dimensions of the cabin were intentionally comparable to the narrowbody airliners of Airbus and Boeing to permit greater comfort levels than most regional aircraft. Considerable attention to detail was reportedly paid by Embraer to elevating the type's passenger appeal. Many operators have chosen to outfit their aircraft with amenities such as Wi-Fi and at-seat power outlets. The windows of the E-Jet family are relatively large at in comparison to most contemporary airliners, such as the windows of the Boeing 787. Operational history In early March 2004, the first E170 deliveries were made to LOT Polish Airlines, other customers to receive early deliveries were Alitalia and US Airways-subsidiary MidAtlantic Airways. On 17 March 2004, LOT operated the first commercial flight of an E-Jet, which flew from Warsaw to Vienna. Within four years, LOT was sufficiently pleased with the type to order 12 additional E175s. Launch customer Crossair had in the meantime ceased to exist after its takeover of
