119-529: The ATR 72 is a twin-engine turboprop , short-haul regional airliner developed and produced in France and Italy by aircraft manufacturer ATR . The number "72" in its name is derived from the aircraft's typical standard seating capacity of 72 passengers. The ATR 72 has also been used as a corporate transport , cargo aircraft , and maritime patrol aircraft . To date, all of the ATR series have been completed at

The main sensors are A tactical display is added to the glass cockpit and can be integrated with INS / GPS positioning systems and IFF transponder . Three U/ VHF radios , one HF radio and a wideband SATCOM are used for communications. Other sensors, systems and communications equipment can be integrated, like an electronic support measure (ESM) system. A defensive aids sub-system (DASS)
357-399: A backlog of 231 orders. By then, with more than 60 -500s and 40 -600s in storage, new aircraft leases fell to $ 130,000 per month from $ 170,000. The -600 list price of $ 26.8M is typically discounted by 25% for a $ 20.1M value, a 2012 aircraft is valued $ 13.3M and leased $ 115,000, falling to $ 10.2M and $ 100,000 in 2021, a D check costs $ 0.5M and the engine overhaul costs $ 0.3-1.0M. The ATR 72
476-583: A business. The 2015 version is also less prescriptive than its predecessors and focuses on performance. This was achieved by combining the process approach with risk-based thinking, and employing the Plan-Do-Check-Act cycle at all levels in the organization. Some of the key changes include: Two types of auditing are required to become registered to the standard: auditing by an external certification body (external audit) and audits by internal staff trained for this process (internal audits). The aim
595-466: A civil aircraft, some ATR 72s have been adapted to perform in various military functions, such as utility aircraft and maritime patrol aircraft (MPA). The Turkish Navy , which initially decided to purchase ten ATR 72-500 MPA, later changed its order to eight aircraft: Two ATR 72-600 TMUA (Turkish Maritime Utility Aircraft) versions, and six ATR 72-600 TMPA (Turkish Maritime Patrol Aircraft for MP/ ASW / ASuW duties) versions. The armed ATR 72 TMPA variant
714-426: A company is interested in certification before quality. Certifications are in fact often based on customer contractual requirements rather than a desire to actually improve quality. ISO's Roger Frost suggested: "If you just want the certificate on the wall, chances are you will create a paper system that doesn't have much to do with the way you actually run your business." Certification by an independent auditor
833-651: A company's tasks and activities, instead of just inspection of the final product). The 2000 version also demanded involvement by upper executives in order to integrate quality into the business system and avoid delegation of quality functions to junior administrators. Another goal was to improve effectiveness via process performance metrics: numerical measurement of the effectiveness of tasks and activities. Expectations of continual process improvement and tracking customer satisfaction were made explicit. ISO 9000 Requirements include: ISO 9001:2008 in essence re-narrates ISO 9001:2000. The 2008 version only introduced clarifications to

Sroufe and Curkovic, (2008) found benefits ranging from registration required to remain part of a supply base, better documentation, to cost benefits, and improved involvement and communication with management. According to ISO the 2015 version of the standard brings the following benefits: A common criticism of ISO 9000 and 9001
1071-406: A constant-speed propeller increase their pitch as aircraft speed increases. Another benefit of this type of propeller is that it can also be used to generate reverse thrust to reduce stopping distance on the runway. Additionally, in the event of an engine failure, the propeller can be feathered , thus minimizing the drag of the non-functioning propeller. While the power turbine may be integral with
1190-413: A deal with flag carrier Iran Air for a batch of 20 ATR 72-600s, along with options for 20 more aircraft and post-purchase services, such as engine maintenance. Made possible by a negotiated relaxation of international sanctions against Iran, during June 2017, a €1 billion Iranian contract was finalized for the firm 20 airliners and 20 options; the delivery of the first four aircraft occurred within weeks of

#17327719767481428-480: A high degree of commonality with the smaller ATR 42 , which remains in production as of 2024. ATR ( French : Avions de transport régional or Italian : Aerei da Trasporto Regionale ) is a joint venture formed by French aerospace company Aérospatiale (now part of Airbus ) and Italian aviation conglomerate Aeritalia (now Leonardo S.p.A. ). During the 1980s, French aerospace company Aérospatiale and Italian aviation conglomerate Aeritalia merged their work on

Propellers work well until the flight speed of the aircraft is high enough that the airflow past the blade tips reaches the speed of sound. Beyond that speed, the proportion of the power that drives
1666-472: A larger 100-seat aircraft. During the mid-2010s, reports emerged that the development of a further stretched 90-seat ATR model was under consideration as well; allegedly, shareholder Airbus was relatively unenthusiastic on proceeding with such a development, while Airbus CEO Fabrice Brégier favoured a focus on resolving manufacturing issues. However, in January 2018, ATR's parent company Leonardo announced that
1785-485: A new generation of regional aircraft. The new jointly owned company, ATR, was established to develop, manufacture, and market their first airliner, later designated the ATR 42 . On 16 August 1984, the first model of the series, designated as the ATR 42-300, performed the type's maiden flight . During the mid-1980s, the ATR 72 was developed as a stretched variant of the ATR 42. On 27 October 1989, Finnish airline Finnair became
1904-608: A new office in Beijing and hired several former Airbus sales personnel with the aim of launching the type in the Chinese market. ATR believed that many of the already-flown routes did not suit larger 150-seat aircraft; however, of the roughly 2,600 commercial aircraft flying in China at that time, only 68 had a capacity of less than 90 seats and of these, fewer than 20 were powered by turboprop engines. In response to airlines often wanting to replace their early production ATR models with
2023-451: A particular scope (e.g., production of golf balls) and displays the addresses to which the certificate refers. An ISO 9001 certificate is not a once-and-for-all award but must be renewed, in accordance with the requirements of ISO 17021, at regular intervals recommended by the certification body, usually once every three years. There are no grades of competence within ISO 9001: either a company
2142-455: A single year. By the end of 2014, ATR had received 1,000 orders for the type and delivered 754, leaving a backlog of 246 aircraft. Various organisational changes were implemented within the ATR company. On 10 July 1998, ATR launched its new Asset Management Department. In June 2001, EADS and Alenia Aeronautica , ATR's parent companies, decided to reinforce their partnership, regrouping all industrial activities related to regional airliners into
2261-561: A superior return on assets compared to otherwise similar organizations without certification. Heras et al. found similarly superior performance and demonstrated that this was statistically significant and not a function of organization size. Naveha and Marcus claimed that implementing ISO 9001 led to superior operational performance in the U.S. automotive industry . Sharma identified similar improvements in operating performance and linked this to superior financial performance. Chow-Chua et al. showed better overall financial performance
2380-498: A tail stand is set into place as standard procedure to guard against the aircraft nose lifting off the ground. 2011 was a record-breaking year for sales at ATR. According to ATR's CEO Filippo Bagnato, sales had continued to grow during the Great Recession despite the downturn experienced by most aviation companies as "fuel consumption that can be half that of the alternatives and [with] lower maintenance costs". Bagnato noted
2499-591: A test-bed not intended for production. It first flew on 20 September 1945. From their experience with the Trent, Rolls-Royce developed the Rolls-Royce Clyde , the first turboprop engine to receive a type certificate for military and civil use, and the Dart , which became one of the most reliable turboprop engines ever built. Dart production continued for more than fifty years. The Dart-powered Vickers Viscount

It is considered healthier for internal auditors to audit outside their usual management line to bring a degree of independence to their judgements. Supporting papers are provided by the ISO 9001 Auditing Practices Group. This

2975-427: Is certified (meaning that it is committed to the method and model of quality management described in the standard) or it is not. In this respect, ISO 9001 certification contrasts with measurement-based quality systems. The ISO 9000 standard is continually being revised by standing technical committees and advisory groups, who receive feedback from those professionals who are implementing the standard. ISO 9000:1987 had

The ISO 9001 standard is generic; its parts must be carefully interpreted to make sense within a particular organization. Developing software
3213-409: Is effective as a guideline, but that promoting it as a standard "helps to mislead companies into thinking that certification means better quality, ... [undermining] the need for an organization to set its own quality standards". In short, Wade argues that reliance on the specifications of ISO 9001 does not guarantee a successful quality system. The standard is seen as especially prone to failure when
3332-498: Is installed within the C4 cargo section. Most operators of the ATR 72 equip their aircraft with a propeller brake that stops the propeller on the No. 2 (right) engine while allowing the turbine to continue running, to provide both airflow and electrical power to the aircraft while on the ground. (This arrangement is referred to as "Hotel Mode".) In the majority of configurations, passengers board
3451-482: Is normally a constant-speed (variable pitch) propeller type similar to that used with larger aircraft reciprocating engines , except that the propeller-control requirements are very different. Due to the turbine engine's slow response to power inputs, particularly at low speeds, the propeller has a greater range of selected travel in order to make rapid thrust changes, notably for taxi, reverse, and other ground operations. The propeller has 2 modes, Alpha and Beta. Alpha

That being said there is no requirement to cite scientific or industrial guidelines/textbooks/journals. Diverse organizations—police departments (United States), professional soccer teams (Mexico), and city councils (UK)—have successfully implemented ISO 9001 systems. Over time, various industry sectors have wanted to standardize their interpretations of

Dalgleish argues: "...[while] quality has a positive effect on return on investment, market share, sales growth, better sales margins, and competitive advantage,...taking a quality approach is unrelated to ISO 9000 registration." In fact, ISO itself advises that ISO 9001 can be implemented without certification, simply for
3927-419: Is only for documentation. Proponents believe that if a company has documented its quality systems, then most of the paperwork has already been completed." Wilson suggests that ISO standards "elevate inspection of the correct procedures over broader aspects of quality", and therefore, "the workplace becomes oppressive and quality is not improved". One study showing reasons for not adopting this standard include

Primary ATR 72 airline operators (with 15 aircraft or more) were: The ATR 72 has been involved in 66 aviation accidents and incidents , including 40 hull losses , resulting in 532 fatalities. As of August 2024, there have been 13 accidents with at least one fatality reported. The first fatal accident involving
4165-494: Is sacrificed in favor of shaft power, which is obtained by extracting additional power (beyond that necessary to drive the compressor) from turbine expansion. Owing to the additional expansion in the turbine system, the residual energy in the exhaust jet is low. Consequently, the exhaust jet produces about 10% of the total thrust. A higher proportion of the thrust comes from the propeller at low speeds and less at higher speeds. Turboprops have bypass ratios of 50–100, although
4284-561: Is some evidence of this, the improvement is partly driven by the fact that there is a tendency for better-performing companies to seek ISO 9001 certification. The mechanism for improving results has also been the subject of much research. Lo et al. (2007) identified operational improvements (e.g., cycle time reduction, inventory reductions) as following from certification. Internal process improvements in organizations lead to externally observable improvements. The benefit of increased international trade and domestic market share, in addition to

Dalgleish cites the "inordinate and often unnecessary paperwork burden" of ISO, and says that "quality managers feel that ISO's overhead and paperwork are excessive and extremely inefficient". The level of minimum documentation for a minimum scope organization has been greatly reduced, going from ISO 9001:2000 to ISO 9001:2008 to ISO 9001:2015. According to Barnes: "Opponents claim that it

The Beta mode is further broken down into 2 additional modes, Beta for taxi and Beta plus power. Beta for taxi as the name implies is used for taxi operations and consists of all pitch ranges from the lowest alpha range pitch, all
4641-613: The Civil Aviation Administration of China (CAAC). By 2013, while the Asia Pacific region had comprised the majority of ATR's sales when geographically ranked; however, orders from Chinese airlines remained elusive; Bagnato ascribed this anomaly to local market conditions dictating the typical use of larger aircraft, as well as a Chinese government policy of imposing high tariffs on the import of foreign-built fixed-wing aircraft. During late 2014, ATR set up

Between 2012 and 2016, the ATSB observed 417 events with turboprop aircraft, 83 per year, over 1.4 million flight hours: 2.2 per 10,000 hours. Three were "high risk" involving engine malfunction and unplanned landing in single‑engine Cessna 208 Caravans , four "medium risk" and 96% "low risk". Two occurrences resulted in minor injuries due to engine malfunction and terrain collision in agricultural aircraft and five accidents involved aerial work: four in agriculture and one in an air ambulance .

Certification bodies themselves operate under another quality standard, ISO/IEC 17021, while accreditation bodies operate under ISO/IEC 17011. An organization applying for ISO 9001 certification is audited based on an extensive sample of its sites, functions, products, services, and processes.

While passengers are boarding or disembarking,
5831-478: The ATR consortium. On 3 October 2003, ATR became one of the first aircraft manufacturers to be certified under ISO 9001-2000 and EN/AS/JISQ 9100 , the worldwide quality standard for the aeronautics industry. During July 2004, ATR and Brazilian aircraft manufacturer Embraer announced a co-operation agreement on the AEROChain Portal to deliver improved customer service. During April 2009, ATR announced
5950-531: The French Directorate General for Civil Aviation . The following month, on 27 October 1989, Finnish airline Finnair became the first to introduce the aircraft into service. Since the ATR 72 is assembled on the same production line as the smaller ATR 42, along with sharing the majority of subsystems, components, and manufacturing techniques, the two types support each other to remain in production. This factor may have been crucial as, by 2015,

That same year, during which firm orders for 10 ATR 42-600s and 79 ATR 72-600s were recorded, leasing companies were responsible for 70 per cent of these; according to ATR's CEO Filippo Bagnato: "Years ago, we were not even considered by the lessors; now they see ATRs as a good investment". Several major leasing companies operate their own ATR fleets, such as Dubai Aerospace Enterprise (DAE), who placed an order for 20 ATR 72s along with options for another 20 in February 2014, and Nordic Aviation Capital (NAC), who ordered
8330-639: The earlier -500 model, differences include adopting improved PW127M engines, a new glass cockpit , and various other minor improvements. Since 2008, ATR has been a participant in the European Clean Sky Joint Technology Initiative. On 8 July 2015, an ATR 72-600 'green' technology demonstrator performed its first flight; the demonstrator was used for testing new composite materials for insulation , air conditioning systems, electrical distribution systems, and energy dispersal modifications to evaluate their effect on
8449-464: The early days, the ISO 9001 (9002 and 9003) requirements were intended to be used by procuring organizations, such as contractors and design activities, as the basis of contractual arrangements with their suppliers. This helped reduce the need for subcontract supplier quality development by establishing basic requirements for a supplier to assure product quality. The ISO 9001 requirements could be tailored to meet specific contractual situations, depending on
8568-439: The existing requirements of ISO 9001:2000 and some changes intended to improve consistency with ISO 14001:2004 . There were no new requirements. For example, in ISO 9001:2008, a quality management system being upgraded just needs to be checked to see if it is following the clarifications introduced in the amended version. ISO 9001 is supplemented directly by two other standards of the family: Other standards, like ISO 19011 and
8687-499: The first jet aircraft and comparable to jet cruising speeds for most missions. The Bear would serve as their most successful long-range combat and surveillance aircraft and symbol of Soviet power projection through to the end of the 20th century. The USA used turboprop engines with contra-rotating propellers, such as the Allison T40 , on some experimental aircraft during the 1950s. The T40-powered Convair R3Y Tradewind flying-boat
8806-442: The first airline to operate this type of revenue service. During the mid-1980s, ATR sought to introduce a larger airliner with increased capacity over its earlier products. This new regional airliner, designated as the ATR 72, was directly developed from the earlier ATR 42 and had much in common with it; the principal difference between the two airliners was an increase in the maximum seating capacity from 48 to 78 passengers. This
8925-564: The first deliveries of the Garrett AiResearch TPE331 , (now owned by Honeywell Aerospace ) on the Mitsubishi MU-2 , making it the fastest turboprop aircraft for that year. In contrast to turbofans , turboprops are most efficient at flight speeds below 725 km/h (450 mph; 390 knots) because the jet velocity of the propeller (and exhaust) is relatively low. Modern turboprop airliners operate at nearly
9044-487: The footprint that it had in 2005. Speaking in October 2015, ATR CEO Patrick de Castelbajac stated that the firm was set to produce in excess of 90 aircraft that year, and that the new manufacturing facilities could support a production rate of up to 120 per year. At the time, the company had a backlog of orders for 300 aircraft, sufficient for three years of production. During 2017, a new in-house financing and leasing division
9163-629: The four P-72As on order to be adapted to the ASW configuration. In December 2016, the first pair of P-72A aircraft were delivered to the Italian Air Force. The last aircraft was delivered to the Italian Air Force in February 2021. A single ATR 72 MP was ordered by Italy's paramilitary Guardia di Finanza (GdF) in July 2019, followed by an order for a further three ATR 72s in October 2019. The aircraft, called P-72B by Guardia di Finanza, will supplement
9282-570: The gas generator section, many turboprops today feature a free power turbine on a separate coaxial shaft. This enables the propeller to rotate freely, independent of compressor speed. Alan Arnold Griffith had published a paper on compressor design in 1926. Subsequent work at the Royal Aircraft Establishment investigated axial compressor-based designs that would drive a propeller. From 1929, Frank Whittle began work on centrifugal compressor-based designs that would use all
9401-460: The gas power produced by the engine for jet thrust. The world's first turboprop was designed by the Hungarian mechanical engineer György Jendrassik . Jendrassik published a turboprop idea in 1928, and on 12 March 1929 he patented his invention. In 1938, he built a small-scale (100 Hp; 74.6 kW) experimental gas turbine. The larger Jendrassik Cs-1 , with a predicted output of 1,000 bhp,
9520-408: The guidelines within their own marketplace. This is partly to ensure that their versions of ISO 9000 have their specific requirements, but also to try and ensure that more appropriately trained and experienced auditors are sent to assess them and even certify according to that interpretation. The debate on the effectiveness of ISO 9000 commonly centers on the following questions: The effectiveness of
9639-411: The internal benefits such as customer satisfaction , interdepartmental communications, work processes, and customer/supplier partnerships derived, far exceeds any and all initial investment. The increase in ISO 9001 certification is shown in the tables below. The ISO 9000 series are based on seven quality management principles (QMP), namely: ISO 9001:2015 Quality management systems — Requirements
9758-597: The latest generation ATR series, as well as to answer demand from cargo operators for the type, ATR has operated two separate dedicated freighter conversion programmes, known as the Bulk Freighter (tube version) and the ULD Freighter. Both conversions involve complete stripping of furnishings along with the addition of floor strengthening, new window plugs and 9 g restraining nets, six additional longitudinal tracks for added flexibility, and an E-Class cabin;
9877-492: The launch of its 'Door-2-Door' service as a new option in its comprehensive customer services range. In 2017, the 72-600 unit cost was US$ 26 million. As of October 2007, the current production version is the ATR 72-600 series. On 2 October 2007, ATR CEO Stéphane Mayer announced the launch of the -600 series aircraft; the ATR 42-600 and ATR 72-600 featured various improvements to increase efficiency, dispatch reliability, lower fuel burn, and operating costs. While broadly similar to
9996-406: The model, such as an overspeed and fuel topping governor on a Pratt & Whitney Canada PT6 , and an under-speed governor on a Honeywell TPE331 . The turboprop is also distinguished from other kinds of turbine engine in that the fuel control unit is connected to the governor to help dictate power. To make the engine more compact, reverse airflow can be used. On a reverse-flow turboprop engine,
10115-504: The most widely used management tools in the world today. However, the ISO certification process has been criticised as being wasteful and not being useful for all organizations. ISO 9000 was first published in 1987 by the International Organization for Standardization (ISO). It was based on the BS 5750 series of standards from BSI that were proposed to ISO in 1979. However, its history can be traced back some twenty years before that, to
10234-623: The most widespread turboprop airliners in service were the ATR 42 / 72 (950 aircraft), Bombardier Q400 (506), De Havilland Canada Dash 8 -100/200/300 (374), Beechcraft 1900 (328), de Havilland Canada DHC-6 Twin Otter (270), Saab 340 (225). Less widespread and older airliners include the BAe Jetstream 31 , Embraer EMB 120 Brasilia , Fairchild Swearingen Metroliner , Dornier 328 , Saab 2000 , Xian MA60 , MA600 and MA700 , Fokker 27 and 50 . Turboprop business aircraft include
10353-402: The newer PW127 engine, rated at a maximum of 2,050 kW (2,750 shp) to achieve improved " hot and high " takeoff performance. It can land and takeoff in high airports with short runways like Andorra Airport . It employs carbonfibres for 30% of the wing by weight, for a 20% weight reduction. In a standard configuration, the aircraft does not have an auxiliary power unit ; when present it
10472-577: The organization to issue and communicate a documented quality policy , a quality management system scope, and quality objectives. The standard no longer requires compliant organizations to issue a formal Quality Manual. The standard does require the retention of numerous records, as specified throughout the standard. New for the 2015 release is a requirement for an organization to assess risks and opportunities (section 6.1) and to determine internal and external issues relevant to its purpose and strategic direction (section 4.1). The organization must demonstrate how
10591-416: The pilot not being able to see out of the rear of the aircraft for backing and the amount of debris reverse stirs up, manufacturers will often limit the speeds beta plus power may be used and restrict its use on unimproved runways. Feathering of these propellers is performed by the propeller control lever. The constant-speed propeller is distinguished from the reciprocating engine constant-speed propeller by
10710-403: The point of exhaust. Some of the power generated by the turbine is used to drive the compressor and electric generator . The gases are then exhausted from the turbine. In contrast to a turbojet or turbofan , the engine's exhaust gases do not provide enough power to create significant thrust, since almost all of the engine's power is used to drive the propeller. Exhaust thrust in a turboprop
10829-592: The predecessor PW127M powerplant. Considerable emphasis has been placed upon the continuous development of ATR's aircraft models. Speaking at the Farnborough Airshow in July 2016, the CEO of ATR Patrick de Castelbajac stated that the company was currently examining the possibility of replacing the current Pratt & Whitney Canada PW127 engine with either a new offer from P&WC, or a GE38 derivative from GE Aviation . Although expressing satisfaction with
10948-494: The propeller that is converted to propeller thrust falls dramatically. For this reason turboprop engines are not commonly used on aircraft that fly faster than 0.6–0.7 Mach , with some exceptions such as the Tupolev Tu-95 . However, propfan engines, which are very similar to turboprop engines, can cruise at flight speeds approaching 0.75 Mach. To maintain propeller efficiency across a wide range of airspeeds, turboprops use constant-speed (variable-pitch) propellers. The blades of
11067-485: The propeller. This allows for propeller strike or similar damage to occur without damaging the gas generator and allowing for only the power section (turbine and gearbox) to be removed and replaced in such an event, and also allows for less stress on the start during engine ground starts. Whereas a fixed shaft has the gearbox and gas generator connected, such as on the Honeywell TPE331 . The propeller itself
11186-450: The propulsion airflow is less clearly defined for propellers than for fans. The propeller is coupled to the turbine through a reduction gear that converts the high RPM /low torque output to low RPM/high torque. This can be of two primary designs, free-turbine and fixed. A free-turbine turboshaft found on the Pratt & Whitney Canada PT6 , where the gas generator is not connected to
11305-789: The publication of government procurement standards, such as the United States Department of Defense MIL-Q-9858 standard in 1959, and the United Kingdom's Def Stan 05–21 and 05–24. Large organizations that supplied government procurement agencies often had to comply with a variety of quality assurance requirements for each contract awarded, which led the defense industry to adopt mutual recognition of NATO AQAP, MIL-Q, and Def Stan standards. Eventually, industries adopted ISO 9000 instead of forcing contractors to adopt multiple—and often similar—requirements. The global adoption of ISO 9001 may be attributable to several factors. In
11424-431: The quality management system. ISO 9001:2000 replaced all three former standards of 1994 issues, ISO 9001 , ISO 9002, and ISO 9003 . Design and development procedures were required only if a company does, in fact, engage in the creation of new products. The 2000 version sought to make a radical change in thinking by actually placing front and center the concept of process management (the monitoring and optimization of
11543-487: The requirements of sections 4 to 10. Sections 1 to 3 are not directly audited against, but because they provide context and definitions for the rest of the standard, not that of the organization, their contents must be taken into account. The standard no longer specifies that the organization shall issue and maintain documented procedures, but ISO 9001:2015 requires the organization to document any other procedures required for its effective operation. The standard also requires
11662-431: The requirements that organizations wishing to meet the standard must fulfill. A companion document, ISO/TS 9002, provides guidelines for the application of ISO 9001. ISO 9004 gives guidance on achieving sustained organizational success. Third-party certification bodies confirm that organizations meet the requirements of ISO 9001. Over one million organizations worldwide are independently certified, making ISO 9001 one of
11781-470: The risks and uncertainty of not knowing if there are direct relationships to improved quality, and what kind and how many resources will be needed. Additional risks include how much certification will cost, increased bureaucratic processes and risk of poor company image if the certification process fails. According to John Seddon , ISO 9001 promotes specification, control , and procedures rather than understanding and improvement. Wade argues that ISO 9000
11900-592: The same speed as small regional jet airliners but burn two-thirds of the fuel per passenger. Compared to piston engines, their greater power-to-weight ratio (which allows for shorter takeoffs) and reliability can offset their higher initial cost, maintenance and fuel consumption. As jet fuel can be easier to obtain than avgas in remote areas, turboprop-powered aircraft like the Cessna Caravan and Quest Kodiak are used as bush airplanes . Turboprop engines are generally used on small subsonic aircraft, but
12019-501: The same structure as the UK Standard BS 5750, with three "models" for quality management systems, the selection of which was based on the scope of activities of the organization: ISO 9000:1987 was also influenced by existing U.S. and other Defense Standards ("MIL SPECS"), and so was well-suited to manufacturing. The emphasis tended to be placed on conformance with procedures rather than the overall process of management, which
12138-413: The set of standards as a "family", bringing together the standard for quality management systems and a set of "supporting standards", and their presentation as a family facilitates their integrated application within an organisation. ISO 9000 deals with the fundamentals and vocabulary of QMS, including the seven quality management principles that underlie the family of standards. ISO 9001 deals with
12257-574: The standard's requirements are being met, while the external auditor's role is to determine the quality management system's effectiveness. More detailed interpretation and implementation examples are often sought by organizations seeking more information in what can be a very technical area. The International Organization for Standardization (ISO) does not certify organizations themselves. Numerous certification bodies exist that audit organizations and issue ISO 9001 compliance certificates upon success. Although commonly referred to as "ISO 9000" certification,
12376-509: The strength of Africa as a market for the type, as well at the firm's aircraft being capable of serving destinations that would otherwise be inaccessible to other aircraft due to the austere conditions of many airstrips and runways in the region, as well as the ability to operate autonomously without any reliance upon ground support equipment. For 2013, ATR claimed a 48 percent global market share for regional aircraft deliveries between 50 and 90 seats (comprising both turboprops and jets), making it
12495-432: The testing of all-electric systems architecture using the demonstrator was completed; analysis is set to continue. As a consequence of strong demand for the -600 series, ATR decided to invest in the establishment of a second, more modern final assembly line and acquisition of more hangar space at its Toulouse site, along with a new large completion and delivery area; overall, the manufacturing operation expanded to four times
12614-410: The way down to zero pitch, producing very little to zero-thrust and is typically accessed by moving the power lever to a beta for taxi range. Beta plus power is a reverse range and produces negative thrust, often used for landing on short runways where the aircraft would need to rapidly slow down, as well as backing operations and is accessed by moving the power lever below the beta for taxi range. Due to
12733-570: Was a candidate to replace the German Navy 's P-3 , at least as a stopgap solution from 2025 to 2032. Germany ultimately selected the P-8A Poseidon in 2021. Two sub-types were marketed as the 100 series (-100). Two sub-types were marketed as the 200 series (-200). The -200 was the original production version, powered by Pratt & Whitney Canada PW124B engines rated at 2,400 shp (1,800 kW). Two sub-types were marketed as
12852-620: Was achieved for companies in Denmark. Rajan and Tamimi (2003) showed that ISO 9001 certification resulted in superior stock market performance and suggested that shareholders were richly rewarded for the investment in an ISO 9001 system. While the connection between superior financial performance and ISO 9001 may be seen from the examples cited, there remains no proof of direct causation, though longitudinal studies , such as those of Corbett et al. (2005), may suggest it. Other writers, such as Heras et al. (2002), have indicated that while there
12971-662: Was born under the auspices of the National Accreditation Council of Certification Bodies (NACCB), which has become the United Kingdom Accreditation Service (UKAS) . In addition to many stakeholders' benefits, several studies have identified significant financial benefits for organizations certified to ISO 9001, with an ISO analysis of 42 studies showing that implementing the standard enhances financial performance. Corbett et al. showed that certified organizations achieved
13090-650: Was considered by important specialists in the field as the "beginning of a new era in the development of quality management systems". As a result of the intensive work from this technical committee, the revised standard ISO 9001:2015 was published by ISO on 23 September 2015. The scope of the standard has not changed; however, the structure and core terms were modified to allow the standard to integrate more easily with other international management systems standards. The new ISO 9001:2015 management system standard helps ensure that consumers can secure reliable, desired quality goods and services. This further increases benefits for
13209-458: Was destroyed in a bombing raid. In 1941, the engine was abandoned due to war, and the factory converted to conventional engine production. The first mention of turboprop engines in the general public press was in the February 1944 issue of the British aviation publication Flight , which included a detailed cutaway drawing of what a possible future turboprop engine could look like. The drawing
13328-551: Was developed in cooperation with Turkish Aerospace Industries (TAI), and incorporated additional sensors and mission systems to perform its intended combat role. During 2013, the two ATR 72-600 TMUA aircraft were delivered to the Turkish Navy. The first ATR 72-600 TMPA was delivered in December 2020 and the second one in March 2021 was already in service with Turkish Navy. As of May 2021, 3 ATR 72-600 TMUA aircraft are being operated by
13447-481: Was established by ATR in order to offer customers a greater degree of support and expand the company's range of services. In December 2015, the EASA approved a new high-density seating layout, raising the maximum capacity from 74 to 78 seats. During the 2021 Dubai Airshow in mid-November 2021, ATR debuted the new ATR 72-600 powered by new PW127XT powerplants with 20% lower maintenance cost and 3% lower fuel consumption than
13566-489: Was likely the actual intent. ISO 9000:1994 emphasized quality assurance via preventive actions, instead of just checking final product, and continued to require evidence of compliance with documented procedures. As with the first edition, the down-side was that companies tended to implement its requirements by creating shelf-loads of procedure manuals, and becoming burdened with an ISO bureaucracy. In some companies, adapting and improving processes could actually be impeded by
13685-658: Was operated by the U.S. Navy for a short time. The first American turboprop engine was the General Electric XT31 , first used in the experimental Consolidated Vultee XP-81 . The XP-81 first flew in December 1945, the first aircraft to use a combination of turboprop and turbojet power. The technology of Allison's earlier T38 design evolved into the Allison T56 , used to power the Lockheed Electra airliner, its military maritime patrol derivative
13804-435: Was principally achieved by stretching the fuselage by 4.5 m (15 ft), along with an increase of the wingspan , the use of more powerful engines, and increased fuel capacity by about 10%. On 15 January 1986, the launch of the stretched ATR 72 programme was announced. On 27 October 1988, the prototype performed its maiden flight. One year later, on 25 September 1989, the ATR 72 received airworthiness certification from
13923-647: Was produced and tested at the Ganz Works in Budapest between 1937 and 1941. It was of axial-flow design with 15 compressor and 7 turbine stages, annular combustion chamber. First run in 1940, combustion problems limited its output to 400 bhp. Two Jendrassik Cs-1s were the engines for the world's first turboprop aircraft – the Varga RMI-1 X/H . This was a Hungarian fighter-bomber of WWII which had one model completed, but before its first flight it
14042-603: Was the first turboprop aircraft of any kind to go into production and sold in large numbers. It was also the first four-engined turboprop. Its first flight was on 16 July 1948. The world's first single engined turboprop aircraft was the Armstrong Siddeley Mamba -powered Boulton Paul Balliol , which first flew on 24 March 1948. The Soviet Union built on German World War II turboprop preliminary design work by Junkers Motorenwerke, while BMW, Heinkel-Hirth and Daimler-Benz also worked on projected designs. While
14161-488: Was very close to what the future Rolls-Royce Trent would look like. The first British turboprop engine was the Rolls-Royce RB.50 Trent , a converted Derwent II fitted with reduction gear and a Rotol 7 ft 11 in (2.41 m) five-bladed propeller. Two Trents were fitted to Gloster Meteor EE227 — the sole "Trent-Meteor" — which thus became the world's first turboprop-powered aircraft to fly, albeit as
