context_page_description: The Embraer E-Jet E2 family are medium-range jet airliners developed by Embraer, succeeding the original E-Jet. The program was launched at the Paris Air Show in 2013. The first variant, the E190-E2, took its first flight on 23 May 2016 and was certified on 28 February 2018 before entering service with Widerøe on 24 April.
  The three twinjet variants share the same four-abreast narrow-body fuselage with different lengths and three different new wings, Pratt & Whitney PW1000G turbofans in two sizes, fly-by-wire controls with new avionics, and an updated cabin.
context_section_description: Embraer targets 16 to 24% lower fuel burn and 15–25% lower maintenance cost per seat. In the E190-E2, of the 17.3% better fuel burn, 11% comes from the geared turbofan, 4.8% from the improved aerodynamics of the new high aspect ratio wing and 1.5% from the fly-by-wire's 15% smaller tail surfaces.
  Over a 600 nmi (1,100 km) trip and with a US$72 fuel barrel, Embraer estimates a 97-seat E190-E2 trip cost is 7% lower for a 1% higher seat cost than a 106-seat A220-100, a 120-seat E195-E2 has a 2% higher trip cost but a 10% lower seat cost and 10% lower trip cost and 3% lower seat cost than a 129-seat A220-300; and while a 97-seat E190 had an 18% higher seat cost than a 150-seat A320 and a 23% lower trip cost, an E190-E2 has a 30% lower trip cost for an 8% higher seat cost than a 150-seat A320neo, while an E195-E2 has the same seat cost but 20% lower trip cost. By October, Embraer raised its E190/E195-E2 seat or trip costs claim to roughly 10% better than the A220.
  Built on the first generation E-Jet, its wing is redesigned, and it introduces new pylons, landing gear, horizontal stabilizers, cabin, cabin air system, air cycle machine, bleed air system, and a new fly-by-wire system. The switch to a composite wing was not yet justified economically for a similar shape, the less draggy flaps are single-slotted instead of the more complex double-slotted on the E1, and the engine pylon is shorter. The raised, 11:1 aspect ratio gull-wing partially accommodate the 2.01m (79 in) diameter GTF, larger than the CF34 by 66 cm (26 in), while the trailing arm landing gear is taller for 23–25 cm (9.1–9.8 in) higher door sills, giving a 5 cm (2.0 in) lower nacelles than the E1.
  GE Aviation, Pratt & Whitney, and Rolls-Royce were all possible engine suppliers. In January 2013, Embraer selected the Pratt & Whitney PW1000G Geared Turbofan engine as the exclusive powerplant. Honeywell Primus Epic 2 was selected as the avionics package. In 2014, Alta Precision was selected to produce main landing gear components for the E190/E195 E2.
  Moog Inc was selected to supply the Primary Flight Control System. The E2 features a closed loop fly-by-wire control which reduces weight, increases fuel efficiency, enhances control and increases safety by full envelope protection in all flight phases compared to the first E-Jet. The fuel savings of the now closed loop fly-by-wire control come from the enhanced flight stability and the resulting increased lift (lower tail downward force) and weight savings and drag reductions related to the 26% reduction in the horizontal tail (tailplane) size. The wing structure was lightened by 200 kg (440 lb) thanks to FBW ailerons, also used when braking, avoiding larger wheels and brakes. A 250 ft² horizontal stabilizer is sufficient from 280 ft² on the E190/195.
  The cabin side walls were replaced to gain 1 in (2.5 cm) on each side and new overhead bins are 3 in (7.6 cm) deeper. Baggage bins are enlarged by 40%.
  Basic maintenance inspections will happen every 1,000 flight hours instead of 850 and the intermediate check interval grew to 10,000 flight-hours from 8,500. The heavy-check downtime was reduced by 15% from the E1, no out-of-phase tasks are required, and control and corrosion prevention is required every eight years with 82 tasks down from 240.
