Bombardier CRJ700 series#CRJ550

During the early 1990s, Bombardier Aerospace became interested in developing larger variants of the CRJ 100 and 200 and associated design work commenced in 1994.[https://www.flightglobal.com/news/articles/making-markets-52/ "Making markets."] Flight International, 5 March 1997. The CRJ-X, as the new range was initially designated, sought to compete with larger regional jets such as the Fokker 70, Fokker 100 or the British Aerospace 146.Doyle, Andrew., Jennifer Pite and Graham Warwick.

The CRJ1000, originally launched as the CRJ-900X in February 2007, was developed as a further stretch of the CRJ900 to accommodate up to 100 passengers. The CRJ1000 shares a high level of commonality with the CRJ700 and CRJ900, but featured an improved version of the General Electric CF34 engine, with enhanced high-pressure turbine performance achieved through optimized blade airfoil geometry, software upgrades, and improved cooling. The turbine nozzles were also redesigned to reduce the number of vanes from 48 to 34. The CRJ1000 also introduced a new cabin design with larger overhead luggage bins, larger windows, improved lighting, and redesigned ceiling panels and sidewalls. A prototype aircraft completed its first flight in 2008, followed by the production flight on 28 July 2009 in Montreal. One month into the flight-test program, a fault in the rudder controls was discovered, grounding the jet until February 2010, and deliveries were projected to begin by January 2011.

During 2007, Bombardier launched the CRJ900 NextGen, featuring improvements developed for the CRJ1000. The improvements include improvements to the GE CF34 engine which enhanced fuel economy by 5.5%,{{cite news |author=Bombardier |date=20 June 2017 |title=The Rise and Rise of Regional Aircraft |url=https://www.flightglobal.com/news/articles/insight-from-bombardier-the-rise-and-rise-of-region-438479/ |work=FlightGlobal}} a redesigned cabin with larger overhead bins, and reduced costs by extending maintenance intervals. Mesaba Aviation (now Endeavor Air) operating at the time as Northwest Airlink (now Delta Connection), was the launch customer for the CRJ900 NextGen, and remains the largest operator of the CRJ900. A similar NextGen package was rolled out to the CRJ700 in 2008, with SkyWest Airlines as the launch customer.[http://www.ltbaonline.com/2011/global/manufacturers/new-firm-order-for-four-crj700-nextgen.html "New firm order for four CRJ700 NextGen."] {{Webarchive|url=https://web.archive.org/web/20110713235331/http://www.ltbaonline.com/2011/global/manufacturers/new-firm-order-for-four-crj700-nextgen.html |date=13 July 2011}} LTBAonline News, January 2011.

During 2016, Bombardier further modernized the CRJ Series with the "Atmosphere" cabin, which included a more spacious entryway, larger overhead bins, larger windows situated higher upon the fuselage, a larger forward lavatory on the CRJ900 and CRJ1000, and LED accent lighting.{{cite web |last= |date=10 May 2016 |title=CRJ Series New Cabin Design |url=https://www.youtube.com/watch?v=oROtdilnDRY&ved=0ahUKEwit6v2mrfrMAhUJHlIKHUCiBzgQtwIIHTAC&usg=AFQjCNFgFbVVKuRR6O5GPK-0nX60z4Qj7A&sig2=pEf5y9TAGYKn6sqKXDJ9EQ |url-status=dead |archive-url=https://web.archive.org/web/20200421065101/https://www.youtube.com/watch?v=oROtdilnDRY&gl=US&hl=en |archive-date=21 April 2020 |website=Bombardier Aerospace |via=YouTube}} Maintenance intervals were also further extended, with "A" checks occurring every 800 flight hours and "C" checks every 8,000 flight hours. A new engine nozzle provided an additional 1% fuel efficiency improvement.

Throughout its production, the CRJ family competed with the Embraer E-Jet family series. However, Bombardier ultimately ruled out a re-engining the CRJ to compete with the Embraer E-Jet E2. Bombardier and General Electric studied a NG34 next generation engine using technologies from the GEnx, and even went as far as building a prototype core for testing. However, Bombardier felt that the certification costs and the added weight of newer, more efficient engines would negate potential fuel burn improvements on short-haul regional routes.{{cite news |last=Hemmerdinger |first=Jon |date=22 June 2018 |title=Bombardier will not replace CRJ's CF34s with new engines |url=https://www.flightglobal.com/news/articles/bombardier-will-not-replace-crjs-cf34s-with-new-eng-449649/ |work=FlightGlobal}}

The reconfiguration addresses a shortcoming of the CRJ series: limited overhead storage. Four large storage cabinets are installed on the cabin floor, allowing passengers to stow their carry-on luggage inside the cabin. Aircraft with 50 or fewer seats require only one flight attendant. Because this aircraft has a sizable first-class section, where passengers might typically expect a flight attendant to be dedicated to only serving first-class passengers, the CRJ550 is equipped with a self-service galley area to be stocked with a selection of snacks and a refrigerator with non-alcoholic beverages, enabling first-class passengers to enjoy refreshments at their leisure, particularly when the flight attendant is serving the economy cabin.{{Cite news |last=Snyder |first=Brett |date=28 October 2019 |title=Touring United's New, Ridiculously-Spacious CRJ-550 Aircraft |url=https://crankyflier.com/2019/10/29/touring-uniteds-new-ridiculously-spacious-crj-550-aircraft/ |access-date=14 May 2024 |work=Cranky Flier |language=en-US}}{{Cite news |last=Rabinowitz |first=Jason |date=15 September 2022 |title=Finding USB ports at every seat on unique United CRJ550 is a thrill |url=https://runwaygirlnetwork.com/2022/09/crj550-united-airlines/ |access-date=14 May 2024 |work=Runway Girl Network |language=en-US}}

The CRJ900 is a stretched version of the CRJ700 with up to 90 seats. Internally designated as the RJX, the first CRJ900 (C-FRJX) was modified from the prototype CRJ700 by adding longer fuselage plugs fore and aft of the wings. It was later converted into the prototype CRJ1000 by replacing the fuselage plugs with longer plugs.{{cite web |url=http://www.airliners.net/search/photo.search?regsearch=C-FRJX |title=Photos of C-FRJX in its various incarnations as first prototypes of the CRJ700, CRJ900 and CRJ1000 |publisher=Airliners.net |access-date=3 March 2014}} The CRJ900 also features strakes located at the rear of the plane. The CRJ900 competes with the Embraer 175.{{cite web |title=The Bombardier CSeries Rolls Out but is it A Game Changer? |url=http://airwaysnews.com/blog/2013/03/08/the-bombardier-cseries-rolls-out-but-is-it-a-game-changer/ |website=Airways News |publisher=Airways International, Inc |access-date=28 January 2016 |url-status=dead |archive-url=https://web.archive.org/web/20160312120113/http://airwaysnews.com/blog/2013/03/08/the-bombardier-cseries-rolls-out-but-is-it-a-game-changer/ |archive-date=12 March 2016}} Mesa Air Group was the launch customer for the CRJ900 painted in America West livery. The aircraft model is listed as CL-600-2D24 on the TCCA, FAA, and EASA Type Certificates.

The wing has been widened with additional leading-edge slats, while the tail features increased span and anhedral. The cabin floor has been lowered by 2 inches (5 cm), improving outward visibility by aligning the windows closer to eye level. A recirculation fan aids in cabin temperature control, and the environmental system uses a target temperature setting instead of a traditional hot-cold knob. The aircraft is equipped with a Honeywell RE220 auxiliary power unit,{{cite web |title=RE220 Auxiliary Power Unit |url=https://aerospace.honeywell.com/en/products/auxiliary-power-and-thermal/re220-apu |url-status=dead |archive-url=https://web.archive.org/web/20180210002158/https://aerospace.honeywell.com/en/products/auxiliary-power-and-thermal/re220-apu |archive-date=10 February 2018 |access-date=9 February 2018 |website=aerospace.honeywell.com}} which provides increased airflow to the air conditioning packs and allows for higher altitude and engine start limits. Additionally, a second lavatory has been added at the front of the cabin.

The aircraft is powered by two GE CF34-8C5 engines, each producing of thrust with APR (automatic performance reserve). The engines are managed by a FADEC (full authority digital engine control) system, replacing traditional control cables and fuel-control units for improved efficiency and precision. In typical operations, the CRJ900 cruises 8,000 to 10,000 feet (2,400 to 3,000 m) higher than the CRJ700, with an average true airspeed of 450 to 500 knots (830 to 930 km/h; 520 to 580 mph) at the expense of slightly increased fuel burn. The aircraft has a maximum takeoff weight of {{Convert|84500|lb}}.

In 2018, the CRJ900 had a list price of $48 million, while its market value was approximately $24 million. However, most customers reportedly paid between $20 and $22 million, with American Airlines securing an order for 15 aircraft at under $20 million each. A six-year-old CRJ900 from 2012 was valued at less than $14 million, with projections indicating a 30% depreciation by 2021.{{cite news |url=http://www.aircraftvaluenews.com/crj900-new-pricing-continues-to-undermine-used-values/ |title= CRJ900 New Pricing Continues to Undermine Used Values |author= Aircraft Value News |date= 14 May 2018}}

The CRJ900 family has four sub-variants:

The baseline variant of the CRJ900 with a maximum takeoff weight (MTOW) of {{Convert|80500|lb}} and a range of {{convert|1350|nmi}}.

The "Extended Range" variant of the CRJ900 with an increased MTOW of {{Convert|82500|lb}}, enabling an increased range of {{convert|1593|nmi}}.

The CRJ705 variant was short-lived. In April 2016, Jazz Aviation announced a plan to convert them all to standard CRJ900 configuration with a slightly increased capacity of 76 with 12 business class and 64 economy class seats.{{cite web |date=26 April 2016 |title=Bombardier and Chorus Sign Firm Purchase Agreement for up to 10 CRJ900 Aircraft |url=http://www.bombardier.com/en/media/newsList/details.bombardier-commercialaircraft-20160426-choruscrj900-.bombardiercom.html}} By late February 2018, the conversion process was complete.
