Please see WikipediaWikiProject Aircraft/page content for recommended layout The Embraer R-99 and P-99 are conversions of the ERJ 145 civil Regional jet Airliner, for military purposes The ERJ 145 is the largest of the group. Each jet in the series is powered by two turbofan engines. A turbofan is a type of Jet engine, similar to a Turbojet. It essentially consists of a Ducted fan with a smaller diameter turbojet engine The family's primary competition comes from the Canadair regional jets. Canadair was a civil and military aircraft manufacturer in Canada. Bombardier Aerospace is a division of the Bombardier group It is the third largest aircraft company in the world in terms of yearly delivery of commercial airplanes (behind
The ERJ 145 was launched at the Paris Airshow in 1989 as a stretched and turbofan-powered modification of the EMB 120 Brasilia. The Paris Air Show ( Salon International de l'Aéronautique et de l'Espace Paris-Le Bourget) is an international trade fair for the aerospace business The Embraer EMB 120 Brasilia is a twin- Turboprop Commuter Airliner, produced by Embraer. Key components of this design included:
By 1990, Embraer engineers found that results from wind-tunnel testing were satisfactory, and began considering a significantly different design from the EMB 120. A wind tunnel is a research tool developed to assist with studying the effects of air moving over or around solid objects A modified design was proposed which included:
The second design showed better performance in wind tunnel testing, but the combination of swept wings and wing-mounted engines required a significantly higher undercarriage than previous iterations. In Aviation, the undercarriage or landing gear is the structure (usually wheels that supports an Aircraft on the ground and allows it to taxi The design evolved until late 1991, at which time it was frozen. Though the aircraft went through many alterations before it was finalized, it did retain a few of the original influences of the EMB 120 such as the three abreast seating (2+1) configuration. The key features of the production design included:
The company was seen to be at a disadvantage due to the delay in bringing the aircraft to service, partly because of the change in the aircraft's design. A T-tail is an aircraft tail stabilizer arrangement in which the horizontal surfaces ( Tailplane and elevators are mounted to the top of the The first design was intended to retain as much commonality as possible with the EMB 120. However, the aircraft has sold well thus overcoming the initial setbacks. Embraer delivered 892 units of all variants through 2006, and predicts that another 102 units will be delivered in the 2007-2016 time period. 
The ERJ 140 is based on the ERJ 145 with 96% parts commonality and the same crew type rating. A type rating is an allowance to fly a certain aircraft model that requires additional training beyond the scope of initial license and aircraft class training The only significant changes are a shorter fuselage, a slightly derated engine and an increased range. The fuselage (from the French fuselé "spindle-shaped" is an Aircraft 's main body section that holds crew and passengers or Cargo Derating is the technique employed in power electrical and electronic devices wherein the devices are operated at less than their rated maximum power dissipation taking into consideration At launch, Embraer estimated the cost of an ERJ 140 to be approximately US$15. 2 million. The estimated cost of development of the ERJ 140 was US$45 million. The ERJ 135, with a service entry date of 1999, has 95% parts commonality with the ERJ 145, but is 11. 7 feet (3. 6 m) shorter.
The ERJ 145 seats 50 passengers, the ERJ 140 seats 44, and the ERJ 135 seats 37. The ERJ 140 was designed with fewer seats in order to meet the needs of some major United States airlines, which have an agreement with the pilot union as to the number of 50-seat aircraft that can be operated in their mixed fleets. The United States of America —commonly referred to as the
In 2003, Embraer entered a partnership with the Harbin Aircraft Manufacturing Corporation of Harbin, China. Harbin Aircraft Manufacturing Corporation (HAMC is an aircraft manufacturing company located in Harbin, the capital of the Heilongjiang Province of the People's ( Russian Kharbin) is a Sub-provincial city and the Capital of the Heilongjiang Province in Northeast China. China ( Wade-Giles ( Mandarin) Chung¹kuo² is a cultural region, an ancient Civilization, and depending on perspective a National The resulting company, Harbin Embraer, began producing the ERJ 145 for the Chinese market by assembling kits premanufactured by other worldwide Embraer operations.

By some accounts, the ERJ 145 has a cost of ownership of about $2,500,000 per year.
In March 2007 ExpressJet entered into a short-term agreement to operate some regional routes for JetBlue Airways using its ERJ 145 aircraft.

The physical engines are the same (Rolls Royce Allison AE3007), however, the FADEC (Full Authority Digital Engine/Electronic Control) logic is what differs between the various models in regards to total thrust capability. WikipediaWikiProject Aircraft. Please see WikipediaWikiProject Aircraft/page content for recommended layout WikipediaWikiProject Aircraft. Please see WikipediaWikiProject Aircraft/page content for recommended layout Thrust is a reaction force described quantitatively by Newton 's Second and Third Laws.
The extended range version, the ERJ-145ER, has Rolls Royce AE 3007A engines rated at 31. Finnish Commuter Airlines Oy, trading as Finncomm Airlines, is a regional Airline based in Seinäjoki, Finland. 3kN(7036 lb) thrust, with the option of more powerful AE 3007A1 engines. A, A1, A1P models are mechanically identical but differ in thrust due to variations in FADEC software. The A1E engine, however, has not only new software, but significantly upgraded mechanical components.
The long-range ERJ-145LR aircraft is equipped with Rolls Royce AE 3007A1 engines which provide 15% more power. The engines are flat rated at 33. When an engine is Flat rated it means that an engine of high Horsepower rating is constrained to a lower horsepower rating 1kN (7440 lb) thrust to provide improved climb characteristics and improved cruise performance in high ambient temperatures.
The extra-long-range ERJ-145XR aircraft is equipped with Rolls-Royce AE 3007A1E engines. The high performance engines provide lower specific fuel consumption (SFC) and improved performance in hot and high conditions. Specific fuel consumption, often shortened to SFC, or TSFC is an Engineering term that is used to describe the Fuel efficiency of an Engine The engines also yield a higher altitude for one-engine-inoperable conditions. A flight ceiling is the upper altitudinal limit at which any aircraft may fly given its mechanical abilities " ExpressJet is the sole operator of the ERJ 145XR. ExpressJet Airlines Inc ( is a Regional airline based in Houston, Texas, USA.
Despite the multiple variants, pilots need only one type rating to fly any variant of the ERJ aircraft.

Please see WikipediaWikiProject Aircraft/page content for recommended layout A type rating is an allowance to fly a certain aircraft model that requires additional training beyond the scope of initial license and aircraft class training Companies like ExpressJet Airlines utilize this benefit with their mixed fleet of ERJ135ER/LR and ERJ145EP/LR/XR. Shared type ratings allows operators to utilize a single pilot pool for any ERJ aircraft.
The ERJ 145 family of aircraft has no reported crashes or fatalities due to mechanical malfunction in over 12 million hours (as of January 2008) of flight time for the fleet. There have been a small number of incidents and accidents involving the ERJ 145. In one case a Rio-Sul pilot descended beyond the normal rates and landed at a speed significantly higher than the normal landing speed. Rio Sul Serviços Aéreos Regionais was an Airline based in Rio de Janeiro, Brazil, being a regional airline operating scheduled services to southern Brazil This aircraft tail section cracked and was dragged along the runway.  In the other case, a Continental Express (ExpressJet) flight overran a Cleveland runway in blizzard conditions; there were no injuries and the aircraft was returned to service. Another ExpressJet aircraft crashed on takeoff in Beaumont, Texas during a training flight; that aircraft was a total loss, but again no injuries were sustained.
