This twin-engine turboprop aircraft family initially was known as the Dash 8 series. The original Q100 made its first flight in June 1983; first deliveries followed in October 1984. The Q100 carried 37-39 passengers, and was equipped with 2,150-shp Pratt & Whitney Canada PW120/121 engines. Other models out of production are: the 37-39-passenger Q200 (with 2,150-shp PW123C/D engines) and 50-56-seat Q300 (with 2,500-shp PW123Bs). The 68-78 seat Q400 (with 5,071-shp PW150As) remains in production.

This single-turboprop-powered utility/passenger aircraft first flew in December 1982. Through 2013, Cessna produced 2,319 Caravans of all types. Designed with the small-package delivery segment in mind, Caravan models in production include the Caravan 675 and 208B Grand Caravan. Both are powered by a Pratt & Whitney Canada PT6A-114A turboprop engine rated at 675 shp. Also in production is the upgraded Grand Caravan EX model, featuring a more powerful PT6A-140 turboprop engine. The EX achieved certification in January 2013. Cessna is forecast to deliver 988 Caravans in 2014-23.

Initially, the new ARJ21 regional jet from Commercial Aircraft Corp. of China (Comac) is to be available as the ARJ21-700 78-90-seater, while later introduction of the 98-105-seat ARJ21-900 is a possibility. Power is provided by two GE CF34-10A turbofans producing 18,500 lb. thrust each. Rollout of the first ARJ21-700 occurred in December 2007, followed by first flight in November 2008. Six ARJ21s were built through 2013, and 86 additional examples are forecast for production through 2023. The ARJ21 faces competition from Bombardier and Embraer.

A twin-turbofan, commercial passenger transport aircraft, the C919 targets the international duopoly in narrowbody airliner sales currently enjoyed by Airbus and Boeing. Variants include the baseline C919-200, which seats up to 168 passengers; the C919-100, a 130-seat model that will compete against the Airbus A319; and the C919-300, a larger 190-seat model designed to compete with Airbus’s A321 and Boeing’s 737-800/900. Comac has selected the CFM International Leap-1C engine, with 30,000 lb. thrust, to power the C919. Service entry is planned for 2016.

The TBM 850 is a single-engine, 4-6-passenger, turboprop-powered aircraft that replaced the earlier TBM 700 in 2006. Power is provided by an 850-shp Pratt & Whitney Canada PT6A-66D engine. The aircraft has a range of 1,585 nm. Through 2013, production totaled 339 aircraft. Production of 13 units is forecast for 2014-23. The TBM 900 is an upgraded TBM 850 model introduced in March 2014. It features a new five-blade propeller, winglets and tailcone. Daher-Socata also added a banana-shaped air intake, new exhaust stacks and carbon-fiber cowlings to increase engine airflow circulation.

This is Embraer’s E-Jet family of twin-engine, 70-132-seat regional jetliners. The 70-80 passenger 170 made its first flight in February 2002, followed by the larger 78-88-seat 175 in June 2003. The 170 and the 175 share a common engine in the 14,200-lb.-thrust GE CF34-8E. The 94-114-seat 190 made its initial flight in March 2004, while the 106-122-passenger 195 first flew in December 2004. GE CF34-10E engines, rated 20,000 lb. thrust each, power these models. Additionally, Embraer developed the Lineage 1000, a business jet version of the 190; deliveries began in 2009.

The ERJ 135/140/145 family is a series of twin-engine, 37-50-seat regional jets. The initial model was the 50-seat ERJ 145, which first flew in August 1995; deliveries began in late 1996. The next model was the 37-seat ERJ 135, which made its initial flight in July 1998, followed by deliveries in July 1999. The 44-passenger ERJ 140 first flew in June 2000, with initial deliveries in July 2001. All models use variants of the Rolls-Royce AE 3007A series turbofan. Through 2013, 730 production ERJ 145s were built.

The Australian company GippsAero, which is a subsidiary of India’s Mahindra Aerospace, is developing a 10-seat, single-engine turboprop aircraft dubbed the GA10. The new aircraft is powered by a 450-shp Rolls-Royce 250-B17F engine. The GA10 has a maximum takeoff weight of 4,750 lb. First flight occurred in May 2012. Australian type certification and initial deliveries are planned for 2014. GippsAero is also developing an 18-seat twin-turboprop aircraft called the GA18. This aircraft is a reengineered version of the GAF N24 Nomad, production of which ended in the mid-1980s.
