EMBRAER E-Jets

Encyclopedia : E : EM : EMB : EMBRAER E-Jets

The Embraer E-Jets are a series of twin-engine jet airliners, produced in Brazil. All variants share the same fuselage cross-section and most systems. The 170 and 175 share wings and engines, differing only in fuselage length and maximum take-off weight. The 190 and 195 also share wing and engines in the same manner.

Introduction

The Embraer E-Jets line is composed of two main commercial families, and a business jet variant. The E-170 and E-175 make up the base model aircraft, with the E-190 and E-195 being stretched versions with up-rated engines and strengthened wing 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 EFIS suite.

Announced at the Paris Air Show in 1999, and entering production in 2002, the E-Jet line is a popular and fast spreading line of Regional Jets. Although commonly referred to with simply an "E" prefix, the jets are technically still Embraer Regional Jets ("ERJ"s). Embraer dropped the ERJ prefix in its advertising early in production, in order to eliminate the negative image associated with current regional jets such as the CRJ. The 190/195 series of aircraft have similar capacities to the unstretched versions of the DC-9 and Boeing 737, which have always been considered mainline aircraft.

The E-170 family is the smaller of the two, competing with regional jets such as the Canadair CRJ-900 and the Sukhoi Russian Regional Jet. It also is helping replace aging aircraft such as the BAe-146 and Fokker 70.

The Embraer 170 was the first aircraft of the family to be produced. The first model was rolled out on 29 October 2001. The first test flight was on February 19 of the following year. The aircraft was not revealed to the public until May of 2002 at the Regional Airline Association convention. After a positive response from the airline community, Embraer proceeded with the launch of the stretched E-175 in June 2003. Certification for the 170 took nearly 2 years after the public debut before delivery of the first aircraft to the launch customer LOT Polish Airlines. Following deliveries went to other customers, such as US Airways (currently the largest buyer of the aircraft type). As of 2006, the E-170 is operated in the United States under the colors of Delta Connection, US Airways Express and United Express, with flights being operated by Shuttle America and Republic Airlines.

E-190/195

The E-190 family is a larger stretch of the E-170 model. Falling in the 100 seat range, it competes with smaller mainline jets including the Boeing 717-200 and 737-600 as well as the Airbus A318 and A319. The first flight of the E-190 was in March of 2004, with the first flight of the 195 in December of the same year. The launch customer of the E-190 was low cost carrier jetBlue with 100 orders and 100 options.

Embraer Lineage 1000

Embraer Lineage 1000 concept as of May 2, 2006

On May 2,2006 Embraer announced plans for the Business jet variant of the E-190. This jet would have the same basic structure of the E-190, but would include extended range of up to 4,200 nm, and luxury seating for up to 19.

In-service

The largest single order for any type of E-Jets has come from jetBlue with 100 firm orders for the E-190, and options for 100 more. Both Air Canada and US Airways also hold large orders, and operate established fleets of both families of E-Jets. In February of 2006, US Airways announced that it was converting 57 of its orders for E-170s into 25 firm orders for the E-190, with options for 32 more. From a passenger's point of view, the Embraer jets are a comfortable alternative to both standard regional jets such as the CRJ, and to larger mainline aircraft. The two abreast seating eliminates the dreaded middle seat, yet still affords ample overhead bin space and underseat storage. The seats themselves can vary between airlines, but on average they give slightly more room in both seat pitch and seat width when compared to other airliners. For comparison, on the E-170s operated by US Airways, seats are 18.25 inches wide, with 33 inch seat pitch. On the larger Boeing 737s in US Airway's fleet, seats are only 17 inches wide with 31 inch seat pitch. This added space makes the aircraft desireable to fly from a passenger's viewpoint.
