to give good short-field performance, while the aircraft was to be powered by four 6,500 lbf thrust Avco Lycoming ALF 502H turbofan engines. There were several reasons why a twin engine configuration was not chosen, this being a controversial decision for a relatively small aircraft and dictated by the choice of engine which, despite its "rugged, quiet and fuel efficient" characteristics, needed to be deployed in a four-engine configuration to provide the power and range required by the concept. Such a configuration was considered by British Aerospace to be advantageous in the event of a single engine failure, offering "exceptional three-engine performance" that would appeal to operators in mountainous environments and from "high, hot or poor grade airfields". The programme was initially launched with backing from the UK government, which agreed to contribute 50% of the development costs in return for a share of the revenues from each aircraft sold.''Air International'', January 1974, pp. 19–20. In October 1974, all work on the project was halted as a result of the world economic downturn resulting from the

Prior to the first flight, British Aerospace had forecast that the smaller would significantly outsell the 146-200 variant; however, airlines showed a higher level of interest in the larger 146-200. By 1981, a large assembly line had been completed at British Aerospace's Hatfield site,Velupillai 1981, p. 1243. and the first completed aircraft flew that year, quickly followed by two more prototypes.Hewish 1982, p. 858. By then, the unit cost of the 146-200 was £11 million, and the program cost was £350 million. Initial flight results showed better-than-predicted takeoff and climb performance.

Overview

British Aerospace promoted the BAe 146 to airlines as a "feederliner" and short-haul regional airliner. The airframe of the aircraft and many other key areas were designed to be as simple as possible. The engines lack

at the rear of the fuselage, which has the advantage of being usable during flight and allowing for steep descent rates if required.Velupillai 1981, p. 1245. In addition, the aircraft has full-width wing spoilers, which are deployed immediately on landing. The aircraft proved to be useful on "high-density" regional and short-haul routes. In economy class, the BAe 146 can either be configured in a standard five-abreast layout or a high-density six-abreast layout, making it one of few regional jets that can use a six-abreast layout in economy class. Reportedly, the aircraft is profitable on most routes with only marginally more than half the seats occupied. The BAe 146 is also renowned for its relatively quiet operation, a positive feature that appealed to those operators that wanted to provide services to noise-sensitive airports within cities. The aircraft is one of only a few types that can be used on flights to London City Airport, which has a steep approach and short runway; for several years, the BAe 146 was the only conventional jet aircraft capable of flying from London City Airport.Cockcroft, Lucy

components where possible, and the internal use of firm cost targets and continuous monitoring. British Aerospace also adopted a system of cost guarantees between component suppliers and the operators of the BAe 146 to enforce stringent requirements. Drawing on experience from the Hawker Siddeley Trident and the Airbus A300, both the fuselage and wing were carefully designed for a reduced part-count and complexity.Velupillai 1981, p. 1246.

Early on, the decision to adopt four engines for a feeder airliner rather than two was viewed as atypical by some commentators. Advantages of adopting the four-engine configuration include greater redundancy and superior takeoff performance from short runways, as well as in hot and high conditions. Electrical power is primarily provided by generators located on each of the outboard engines. For ease of maintenance and reduced operator costs, the ALF 502 is of a

design and makes minimum use of specialist tooling. The ALF 502 has experienced multiple issues. Its internal electronics could overheat, triggering an automatic shutdown of an engine with no option for inflight restart, and certain rare atmospheric conditions could cause a loss of engine thrust due to internal icing. Additionally, the BAe 146 experienced some issues with its bleed air and cabin pressurization systems, leading to a number of fume events where irritant fumes were introduced into the cabin by the pressurizing system.

The BAe 146-200QC (Quick Change) is the convertible passenger/freight version and the BAe 146-200QT (Quiet Trader) is the freighter version. Two BAe 146-200QC aircraft, designated BAe 146 C3, were converted for the RAF, with infrared countermeasures systems and flare dispensers, for use in Afghanistan. The Avro RJ85, the first RJ development of the BAe 146 family, features an improved cabin and the more efficient LF 507 engines. Deliveries of the RJ85 began in April 1993. It seats up to 112 passengers.

were to be fitted to the aircraft's wingtips.''Air International'' June 1987, p. 269.''Air International'' November 1984, pp. 266–267. However, due to airlines favouring a lower initial price rather than minimising seat-mile costs, the definitive 146-300 emerged as a less extreme development. Ultimately, the fuselage was stretched by , giving a capacity of 100 passengers seated five-abreast at a 31-inch seat pitch, without winglets or the proposed ALF 502R-7.''Air International'' June 1987, pp. 269–270, 273. Deliveries began in December 1988. A modified BAe 146-301 is used as the UK's

. The BAe 146-300QC (Quick Change) is the convertible passenger/freight version and the BAe 146-300QT (Quiet Trader) is the freighter version. The Avro RJ version of the 146-300, the second such development of the 146 product line, became the Avro RJ100. It shared the fuselage of the 146 version, but with interior, engine, and avionics improvements. The most common configuration in the RJ100 seats 100 passengers. An RJ115 variant, the same physical size, but with an increased MTOW and different emergency exits, was marketed, but never entered production; it sat 116 as standard or up to a maximum of 128 in a high-density layout.


BAe 146STA

Throughout the production life of the BAe 146, British Aerospace proposed a number of specialised military versions, including side- and rear-loading transports, an airborne tanker version,Skinner 2005, p. 21. and a carrier onboard delivery version.Skinner 2005, p. 22. Out of these proposals came the BAe 146STA (Sideloading Tactical Airlifter), based on the BAe 146QT cargo aircraft and sharing its cargo door on the left side of the rear fuselage. This military-transport version has a refuelling probe protruding from the nose; a demonstrator, fitted with a dummy refuelling probe and an air-openable paratroop door, was displayed at the 1989

BAe 146M

BAE Systems announced the BAe 146M programme in 2009, designed to provide ex-civilian BAe 146-200 and -300 aircraft to military operators, available either in passenger or freighter configurations. Upgrades and alterations made to the type include new

avionics, additional fuel tanks, increased steep approach, and unpaved runway operation capabilities, and being outfitted with defensive aids; however, a rear cargo door was not introduced. BAE has stated that the 146M is suitable for performing airlift, medical evacuation, para-drop, surveillance, and inflight refueling operations.


Avro RJX series

The RJX-70, RJX-85, and RJX-100 variants represented advanced versions of the Avro RJ Series. The RJX series used Honeywell AS977 turbofans for greater efficiency (15% less fuel burn, 17% increased range), quieter performance, and 20% lower maintenance costs. Bhutan carrier Drukair ordered two RJX-85s, while

placed firm orders for 12 RJX-100s and eight options. However, BAE Systems terminated the project in December 2001, having completed and flown only three aircraft—a prototype each of the RJX-85 and RJX-100, and a production RJX-100 for British European. BAE reached an agreement with Druk Air and British European in early 2002 in which the airlines agreed not to enforce their firm orders for the RJX. BAE explored the possibility of manufacturing 14 "hybrid" aircraft, but British European at least was unwilling to accept the risk of operating a unique type.
