140-546: The Diamond DA42 Twin Star is a four seat, twin engine, propeller-driven airplane developed and manufactured in Austria and Canada by Diamond Aircraft Industries , an Austrian subsidiary of China-based Wanfeng Aviation . It was Diamond's first twin engine design, as well as the first new European twin-engine aircraft in its category to be developed in over 25 years. In 2004, the DA42 became
280-653: A T-tail . The DA42 incorporates a combination of advanced features within the company's first twin-engine design. The airframe is composed of composite materials , making extensive use of carbon fiber reinforced polymers throughout its structure; this construction provides the aircraft with a suitable passive safety level to conform with the established European Aviation Safety Agency (EASA) Part 21 rules, as well as relatively efficient aerodynamics and essentially unlimited airframe life. The carbon-fiber main wing spars possesses exceptional crashworthiness . The DA42 typically accommodates four people in two rows of seating. All of
420-510: A DA42 powered by Austro AE300 engines became the first aircraft to be publicly flown on algae -derived jet fuel. As a consequence of the insolvency of engine manufacturer Thielert and decisions of the insolvency administrator, including cancelling warranty support and the prorating of time-between-overhaul for the Thielert engines that power the DA42, in July 2008, Diamond announced that production of

However, the production of a plane for one company is a process that actually involves dozens, or even hundreds, of other companies and plants, that produce the parts that go into the plane. For example, one company can be responsible for the production of the landing gear, while another one
700-576: A benchmark for European general aviation". During August 2004, the DA42 Twin Star piloted by Gérard Guillaumaud became the first diesel-powered fixed-wing aircraft to perform a non-stop crossing of the North Atlantic, taking 12.5 hours while operating with an average fuel consumption of 21.73 litres (4.78 imp gal; 5.74 US gal) per hour (10.86 litres (2.39 imp gal; 2.87 US gal) per hour per engine). In June 2010,

During the latter part of 2008 and early 2009, a pair of Royal Air Force DA42 MPPs were deployed for eight months to provide combat support to coalition forces operating in Iraq ; during the deployment, these aircraft flew a combined 2,000h in the surveillance role, for which it had been outfitted with Cineflex high-definition cameras, Riegl laser scanners and Scotty satellite communications kit. The DA42
1400-529: A disproportionate share of defaults. The Economist wrote in July 2012 that the inflow of investment dollars required to fund the U.S. trade deficit was a major cause of the housing bubble and financial crisis: "The trade deficit, less than 1% of GDP in the early 1990s, hit 6% in 2006. That deficit was financed by inflows of foreign savings, in particular from East Asia and the Middle East. Much of that money went into dodgy mortgages to buy overvalued houses, and
1540-737: A first flight. The flight tests continue until the aircraft has fulfilled all the requirements. Then, the governing public agency of aviation of the country authorizes the company to begin production. In the United States, this agency is the Federal Aviation Administration (FAA). In the European Union, European Aviation Safety Agency (EASA); in the United Kingdom it is the Civil Aviation Authority (CAA). In Canada,

It was an important predecessor of his later Blériot XI Channel -crossing aircraft of the summer of 1909. World War I served as a testbed for the use of the airplane as a weapon. Airplanes demonstrated their potential as mobile observation platforms, then proved themselves to be machines of war capable of causing casualties to

Whether flexible or rigid, most wings have a strong frame to give them their shape and to transfer lift from the wing surface to the rest of the aircraft. The main structural elements are one or more spars running from root to tip, and many ribs running from
1960-480: A height of 500 feet (150 m). The Austro engine produces 20% more power than the previous Thielert engines and also results in a higher gross weight and increased performance. Diamond has claimed that the Austro engine is about 46% more fuel efficient than its gasoline rivals. It runs on diesel fuel or jet fuel , both of which are typically cheaper than aviation gasoline . Upon its introduction, Diamond had to combat
2100-509: A historic trend of declining light-piston twin sales in the face of increasingly reliable and capable single-engined aircraft for general aviation; the DA42 had only five competing aircraft in its category. The DA42, particularly its use in the surveillance sector, became Diamond's most important business. A dedicated surveillance model of the aircraft, designated as the DA 42 MPP , was developed; during 2008, Diamond delivered 17 DA 42 MPPs and anticipated
2240-414: A jet-powered aircraft with a speed of Mach 9.7, nearly 12,100 kilometers per hour (7,500 mph). Whereas jet aircraft use the atmosphere both as a source of oxidant and of mass to accelerate reactively behind the aircraft, rocket aircraft carry the oxidizer on board and accelerate the burned fuel and oxidizer backwards as the sole source of mass for reaction. Liquid fuel and oxidizer may be pumped into

But to be structurally efficient, and hence light weight, a wing must have a short span but still enough area to provide lift (low aspect ratio). Great Recession The Great Recession was a period of market decline in economies around the world that occurred from late 2007 to mid-2009. The scale and timing of the recession varied from country to country (see map). At

The Economist , writing at the same time, went further, saying, "[T]he worldwide rise in house prices is the biggest bubble in history". Real estate bubbles are (by definition of the word "bubble") followed by a price decrease (also known as a housing price crash ) that can result in many owners holding negative equity (a mortgage debt higher than

The monitors display various information on the aircraft, along with navigational data and flight information; both screens can show identical basic information or be configured to flight data on the left monitor and navigation on
2800-538: A presence in all the major battles of World War II . The first jet aircraft was the German Heinkel He 178 in 1939. The first jet airliner , the de Havilland Comet , was introduced in 1952. The Boeing 707 , the first widely successful commercial jet, was in commercial service for more than 60 years, from 1958 to 2019. First attested in English in the late 19th century (prior to the first sustained powered flight),
2940-416: A propeller creates is determined, in part, by its disk area—the area through which the blades rotate. The limitation on blade speed is the speed of sound ; as when the blade tip exceeds the speed of sound, shock waves decrease propeller efficiency. The rpm required to generate a given tip speed is inversely proportional to the diameter of the propeller. The upper design speed limit for propeller-driven aircraft

#17330852114483080-443: A relatively low level of effort, not necessitating continuous trimming while the aircraft is accelerating. Active use of the rudder is necessary for effective turns and counteracting sideslip tendencies. While the DA42 is a twin-engined aircraft, this is predominantly a measure for safety. It is readily capable of sustained flight using only a single engine. DA42 NG climbs at up to 270 ft/min at sea level in standard conditions on
3220-572: A resolution preventing CFTC from regulating derivatives for another six months – when Born's term of office would expire. Ultimately, it was the collapse of a specific kind of derivative, the mortgage-backed security , that triggered the economic crisis of 2008. Paul Krugman wrote in 2009 that the run on the shadow banking system was the fundamental cause of the crisis. "As the shadow banking system expanded to rival or even surpass conventional banking in importance, politicians and government officials should have realised that they were re-creating
3360-477: A shaft through a reduction gearing to the propeller. The propelling nozzle provides a relatively small proportion of the thrust generated by a turboprop. An electric aircraft runs on electric motors with electricity coming from fuel cells , solar cells , ultracapacitors , power beaming , or batteries . Currently, flying electric aircraft are mostly experimental prototypes, including manned and unmanned aerial vehicles , but there are some production models on
3500-757: A sharp drop in international trade , rising unemployment and slumping commodity prices. Several economists predicted that recovery might not appear until 2011 and that the recession would be the worst since the Great Depression of the 1930s. Economist Paul Krugman once commented on this as seemingly the beginning of "a second Great Depression". Governments and central banks responded with fiscal policy and monetary policy initiatives to stimulate national economies and reduce financial system risks. The recession renewed interest in Keynesian economic ideas on how to combat recessionary conditions. Economists advise that
3640-465: A similar manner, a single combined power lever is used to regulate both the engine and propeller settings; the power levers are convenient and can be operated in a relatively easy manner. In comparison with other twin-engined aircraft in its category, the centre console of the DA42 is uncluttered, which is a result of the clean design of the controls. The stall characteristics are also relatively benign, being described by Flight International as "probably
3780-634: A single engine, with performance degrading with higher altitudes and temperatures. The DA42 possesses considerable endurance, being capable of performing 13 hour-long flights without carrying additional fuel tanks; this is partially due to its high fuel efficiency of its Austro engines, which consume 13.6 US gallons per hour when operated at 75 per cent power, lower than some of its single-engined rivals. The digital FADEC (full authority digital engine controls) serves to lower operational difficulty, constantly performing tasks such as managing rpm and fault-checking. The propellers are clockwise-rotating as viewed by
3920-426: A single wing plane, a biplane has two stacked one above the other, a tandem wing has two placed one behind the other. When the available engine power increased during the 1920s and 30s and bracing was no longer needed, the unbraced or cantilever monoplane became the most common form of powered type. The wing planform is the shape when seen from above. To be aerodynamically efficient, a wing should be straight with
4060-435: A small and simple engine for high-speed use, such as with missiles. Ramjets require forward motion before they can generate thrust and so are often used in conjunction with other forms of propulsion, or with an external means of achieving sufficient speed. The Lockheed D-21 was a Mach 3+ ramjet-powered reconnaissance drone that was launched from a parent aircraft . A ramjet uses the vehicle's forward motion to force air through
4200-468: A span of 14 m (46 ft). All-up weight was 300 kilograms (660 lb). On 9 October 1890, Ader attempted to fly the Éole . Aviation historians give credit to this effort as a powered take-off and uncontrolled hop of approximately 50 m (160 ft) at a height of approximately 200 mm (7.9 in). Ader's two subsequent machines were not documented to have achieved flight. The American Wright brothers 's flights in 1903 are recognized by
4340-510: A tool for taking excessive risks. Examples of vulnerabilities in the public sector included: statutory gaps and conflicts between regulators; ineffective use of regulatory authority; and ineffective crisis management capabilities. Bernanke also discussed " Too big to fail " institutions, monetary policy, and trade deficits.

According to Kuttner, "recessions are mild dips in the business cycle that are either self-correcting or soon cured by modest fiscal or monetary stimulus. Because of the continuing deflationary trap, it would be more accurate to call this decade's stagnant economy The Lesser Depression or The Great Deflation." The Great Recession met

Examples of triggers included: losses on subprime mortgage securities that began in 2007 and a run on the shadow banking system that began in mid-2007, which adversely affected the functioning of money markets. Examples of vulnerabilities in the private sector included: financial institution dependence on unstable sources of short-term funding such as repurchase agreements or Repos; deficiencies in corporate risk management; excessive use of leverage (borrowing to invest); and inappropriate usage of derivatives as
10360-442: The current value of the property). Several sources have noted the failure of the US government to supervise or even require transparency of the financial instruments known as derivatives . Derivatives such as credit default swaps (CDSs) were unregulated or barely regulated. Michael Lewis noted CDSs enabled speculators to stack bets on the same mortgage securities. This is analogous to allowing many persons to buy insurance on
10500-564: The depository system yet was not subject to the same regulatory oversight, making it vulnerable to a bank run . US mortgage-backed securities , which had risks that were hard to assess, were marketed around the world, as they offered higher yields than U.S. government bonds. Many of these securities were backed by subprime mortgages, which collapsed in value when the U.S. housing bubble burst during 2006 and homeowners began to default on their mortgage payments in large numbers starting in 2007. The emergence of subprime loan losses in 2007 began
10640-469: The design team with a concept for a twin-engined aircraft, which became the company's first multi-engined aircraft, and became the next step beyond the Diamond DA40 . This concept emphasised several key qualities, including the need for the aircraft to be simple to operate and fuel-efficient, while providing a luxurious four-seat passenger compartment akin to modern automobiles. The concept was not popular at
10780-478: The development of the Aeronautics Defense Dominator , a medium-altitude long-endurance (MALE) unmanned aerial vehicle (UAV), which had been derived from the DA42. Since its founding in the 1980s, Austrian manufacturer Diamond Aircraft Industries had concentrated on building an extensive product line. During the late 1990s, company founder and chief executive officer Christian Dries approached
10920-517: The downturn. In advanced economies, during the five years preceding 2007, the ratio of household debt to income rose by an average of 39 percentage points, to 138 percent. In Denmark, Iceland, Ireland, the Netherlands, and Norway, debt peaked at more than 200 percent of household income. A surge in household debt to historic highs also occurred in emerging economies such as Estonia, Hungary, Latvia, and Lithuania. The concurrent boom in both house prices and
11060-412: The earlier Thielert Centurion 1.7 and 2.0 engines and is known for its good fuel efficiency, using 12.1 litres (2.7 imp gal; 3.2 US gal) per hour while loitering at maximum endurance or 30 litres (7 imp gal; 8 US gal) per hour at maximum continuous power (92%). It is also available with optional "on top" exhaust mufflers that reduce noise levels to below 59 decibels at
11200-608: The economic crisis took most people by surprise. A 2009 paper identifies twelve economists and commentators who, between 2000 and 2006, predicted a recession based on the collapse of the then-booming housing market in the United States: Dean Baker , Wynne Godley , Fred Harrison , Michael Hudson , Eric Janszen , Med Jones Steve Keen , Jakob Brøchner Madsen , Jens Kjaer Sørensen, Kurt Richebächer , Nouriel Roubini , Peter Schiff , and Robert Shiller . By 2007, real estate bubbles were still under way in many parts of
11340-405: The economic headwinds that slowed the recovery: On the political front, widespread anger at banking bailouts and stimulus measures (begun by President George W. Bush and continued or expanded by President Obama ) with few consequences for banking leadership, were a factor in driving the country politically rightward starting in 2010. The Troubled Asset Relief Program (TARP) was the largest of
11480-479: The end of WWII all-metal aircraft were common. In modern times, increasing use of composite materials has been made. Typical structural parts include: The wings of a fixed-wing aircraft are static planes extending either side of the aircraft. When the aircraft travels forwards, air flows over the wings, which are shaped to create lift. This shape is called an airfoil and is shaped like a bird's wing. Airplanes have flexible wing surfaces which are stretched across
11620-527: The enemy. The earliest known aerial victory with a synchronized machine gun-armed fighter aircraft occurred in 1915, by German Luftstreitkräfte Leutnant Kurt Wintgens . Fighter aces appeared; the greatest (by number of Aerial Combat victories) was Manfred von Richthofen , also known as the Red Baron. Following WWI, aircraft technology continued to develop. Alcock and Brown crossed the Atlantic non-stop for
11760-426: The engine without resorting to turbines or vanes. Fuel is added and ignited, which heats and expands the air to provide thrust. A scramjet is a specialized ramjet that uses internal supersonic airflow to compress, combine with fuel, combust and accelerate the exhaust to provide thrust. The engine operates at supersonic speeds only. The NASA X-43 , an experimental unmanned scramjet, set a world speed record in 2004 for
11900-423: The financial crisis was the result." In May 2008, NPR explained in their Peabody Award winning program " The Giant Pool of Money " that a vast inflow of savings from developing nations flowed into the mortgage market, driving the U.S. housing bubble. This pool of fixed income savings increased from around $ 35 trillion in 2000 to about $ 70 trillion by 2008. NPR explained this money came from various sources, "[b]ut
12040-552: The first diesel-powered fixed-wing aircraft to perform a non-stop crossing of the North Atlantic . By 2012, the DA42 had become a key revenue generator for the company, having gained popularity with government and military operators in addition to the civil market that had suffered as a result of the Great Recession . Government customers have typically employed the type in the aerial surveillance role, which contributed towards
12180-609: The first time in 1919. The first international commercial flights took place between the United States and Canada in 1919. Airplanes had a presence in all the major battles of World War II . They were an essential component of the military strategies of the period, such as the German Blitzkrieg , The Battle of Britain , and the American and Japanese aircraft carrier campaigns of the Pacific War . The first practical jet aircraft
12320-402: The following recovery weaker. Robert Reich claims the amount of debt in the US economy can be traced to economic inequality , assuming that middle-class wages remained stagnant while wealth concentrated at the top, and households "pull equity from their homes and overload on debt to maintain living standards". The IMF reported in April 2012: "Household debt soared in the years leading up to
12460-417: The greatest possible degrees of passive safety in operation, alongside excellent fuel economy and assisted by the implementation of various modern technologies. The flight controls themselves are proportionally responsive for performing even small manoeuvers and light motions. Both pilots are equipped with their own fighter-style central sticks , which are attached to an otherwise unobstructed cockpit floor. In
12600-533: The kind of financial vulnerability that made the Great Depression possible – and they should have responded by extending regulations and the financial safety net to cover these new institutions. Influential figures should have proclaimed a simple rule: anything that does what a bank does, anything that has to be rescued in crises the way banks are, should be regulated like a bank." He referred to this lack of controls as "malign neglect". During 2008, three of
12740-568: The largest U.S. investment banks either went bankrupt ( Lehman Brothers ) or were sold at fire sale prices to other banks ( Bear Stearns and Merrill Lynch ). The investment banks were not subject to the more stringent regulations applied to depository banks. These failures exacerbated the instability in the global financial system. The remaining two investment banks, Morgan Stanley and Goldman Sachs , potentially facing failure, opted to become commercial banks, thereby subjecting themselves to more stringent regulation but receiving access to credit via
12880-589: The latter in the form of the Aeronautics Defense Dominator . Also in March 2012, Diamond aircraft announced they were developing a fly-by-wire version of the DA42, which had the stated aim of reducing the accident rate in light aircraft. The system is expected to include flight envelope protection , turbulence righting, autoland capabilities, and damage-tolerant by-pass capabilities, the latter of which would allow for effective flight while suffering from jammed or otherwise non-functional flight surfaces. The autonomous DA42
13020-399: The leading (front) to the trailing (rear) edge. Early airplane engines had little power, and lightness was very important. Also, early airfoil sections were very thin, and could not have a strong frame installed within. So, until the 1930s, most wings were too lightweight to have enough strength, and external bracing struts and wires were added. When the available engine power increased during
13160-581: The main headline is that all sorts of poor countries became kind of rich, making things like TVs and selling us oil. China, India, Abu Dhabi, Saudi Arabia made a lot of money and banked it." Describing the crisis in Europe, Paul Krugman wrote in February 2012 that: "What we're basically looking at, then, is a balance of payments problem, in which capital flooded south after the creation of the euro, leading to overvaluation in southern Europe." Another narrative about
13300-462: The majority and minority opinions of the FCIC, Commissioner Peter J. Wallison of the American Enterprise Institute (AEI) primarily blamed U.S. housing policy, including the actions of Fannie and Freddie , for the crisis. He wrote: "When the bubble began to deflate in mid-2007, the low quality and high risk loans engendered by government policies failed in unprecedented numbers." In its "Declaration of
13440-422: The manufacturer or the customer. The structural parts of a fixed-wing aircraft are called the airframe. The parts present can vary according to the aircraft's type and purpose. Early types were usually made of wood with fabric wing surfaces, When engines became available for powered flight around a hundred years ago, their mounts were made of metal. Then as speeds increased more and more parts became metal until by
13580-440: The market. Jet aircraft are propelled by jet engines , which are used because the aerodynamic limitations of propellers do not apply to jet propulsion. These engines are much more powerful than a reciprocating engine for a given size or weight and are comparatively quiet and work well at higher altitude. Variants of the jet engine include the ramjet and the scramjet , which rely on high airspeed and intake geometry to compress
13720-406: The modern airplane as a fixed-wing flying machine with separate systems for lift, propulsion, and control. Cayley was building and flying models of fixed-wing aircraft as early as 1803, and he built a successful passenger-carrying glider in 1853. In 1856, Frenchman Jean-Marie Le Bris made the first powered flight, by having his glider "L'Albatros artificiel" pulled by a horse on a beach. Then
13860-430: The most docile of any aircraft I can remember". On the DA42, stall conditions are forewarned by the sounding of a warning horn at 5 to 7 kn (9 to 13 km/h) above stall, as well as by elevating levels of airframe buffeting and a 5–10° drop of the nose. The aircraft is relatively difficult to stall outside of substantial mishandling or deliberate intention. Both longitudinal and lateral stability can be maintained with
14000-662: The need to take the U.S. economy out of the early 2000s recession caused by the bursting of the dot-com bubble : although by doing so he did not avert the crisis, but only postponed it. Another narrative focuses on high levels of private debt in the US economy. USA household debt as a percentage of annual disposable personal income was 127% at the end of 2007, versus 77% in 1990. Faced with increasing mortgage payments as their adjustable rate mortgage payments increased, households began to default in record numbers, rendering mortgage-backed securities worthless. High private debt levels also impact growth by making recessions deeper and
14140-405: The objective of producing them in quantity for customers. The design and planning process, including safety tests, can last up to four years for small turboprops or longer for larger planes. During this process, the objectives and design specifications of the aircraft are established. First the construction company uses drawings and equations, simulations, wind tunnel tests and experience to predict
14280-535: The obligation and defaulted; U.S. taxpayers paid over $ 100 billion to global financial institutions to honor AIG obligations, generating considerable outrage. A 2008 investigative article in The Washington Post found leading government officials at the time (Federal Reserve Board Chairman Alan Greenspan , Treasury Secretary Robert Rubin , and SEC Chairman Arthur Levitt ) vehemently opposed any regulation of derivatives. In 1998, Brooksley E. Born , head of
14420-484: The origin has been focused on the respective parts played by public monetary policy (notably in the US) and by the practices of private financial institutions. In the U.S., mortgage funding was unusually decentralised, opaque, and competitive, and it is believed that competition between lenders for revenue and market share contributed to declining underwriting standards and risky lending. While Alan Greenspan's role as Chairman of
14560-529: The pilot, so the left engine is the critical engine . The original model of the DA42 was powered by a pair of Thielert Aircraft Engines-built TAE 125-01 Centurion 1.7 engines. However, Thielert ended its production of the 1.7 litre Centurion engines in favour of a new 2.0 litre engine, marketed as the TAE 125-02-99; as a result of the engine production change, Diamond began installing the TAE 125-02-99 engine during early 2007. Although engine displacement had increased, it
14700-588: The planet. Though no one knew they were in it at the time, the Great Recession had a significant economic and political impact on the United States. While the recession technically lasted from December 2007 – June 2009 (the nominal GDP trough), many important economic variables did not regain pre-recession (November or Q4 2007) levels until 2011–2016. For example, real GDP fell $ 650 billion (4.3%) and did not recover its $ 15 trillion pre-recession level until Q3 2011. Household net worth, which reflects
14840-405: The popular claim (narrative #4) that subprime borrowers with shoddy credit caused the crisis by buying homes they couldn't afford. This narrative is supported by new research showing that the biggest growth of mortgage debt during the U.S. housing boom came from those with good credit scores in the middle and top of the credit score distribution – and that these borrowers accounted for
14980-512: The power to set future requirements. These rose to 42 percent in 1995 and 50 percent in 2000, and by 2008 a 56 percent minimum was established. However, the Financial Crisis Inquiry Commission (FCIC) Democratic majority report concluded that Fannie & Freddie "were not a primary cause" of the crisis and that CRA was not a factor in the crisis. Further, since housing bubbles appeared in multiple countries in Europe as well,
15120-410: The protections we had constructed to prevent financial meltdowns. We had a 21st-century financial system with 19th-century safeguards. The Gramm–Leach–Bliley Act (1999), which reduced the regulation of banks by allowing commercial and investment banks to merge, has also been blamed for the crisis, by Nobel Prize –winning economist Joseph Stiglitz among others. Peter Wallison and Edward Pinto of
15260-578: The public agency in charge and authorizing the mass production of aircraft is Transport Canada's Civil Aviation Authority. When a part or component needs to be joined together by welding for virtually any aerospace or defense application, it must meet the most stringent and specific safety regulations and standards. Nadcap , or the National Aerospace and Defense Contractors Accreditation Program sets global requirements for quality, quality management and quality assurance for aerospace engineering. In
15400-402: The recession have been described as a symptom of another, deeper crisis by a number of economists. For example, Ravi Batra argues that growing inequality of financial capitalism produces speculative bubbles that burst and result in depression and major political changes . Feminist economists Ailsa McKay and Margunn Bjørnholt argue that the financial crisis and the response to it revealed
15540-521: The recession took place at the global level. According to the U.S. National Bureau of Economic Research (the official arbiter of U.S. recessions) the recession began in December 2007 and ended in June 2009, and thus extended over eighteen months. The years leading up to the crisis were characterized by an exorbitant rise in asset prices and associated boom in economic demand. Further, the U.S. shadow banking system (i.e., non-depository financial institutions such as investment banks) had grown to rival
15680-488: The recovery was that both individuals and businesses paid down debts for several years, as opposed to borrowing and spending or investing as had historically been the case. This shift to a private sector surplus drove a sizable government deficit. However, the federal government held spending at about $ 3.5 trillion from fiscal years 2009–2014 (thereby decreasing it as a percent of GDP), a form of austerity . Then-Fed Chair Ben Bernanke explained during November 2012 several of
15820-461: The repo margin ("haircut"), forcing massive deleveraging, and resulting in the banking system being insolvent. The Financial Crisis Inquiry Commission reported in January 2011: In the early part of the 20th century, we erected a series of protections – the Federal Reserve as a lender of last resort , federal deposit insurance, ample regulations – to provide a bulwark against the panics that had regularly plagued America's banking system in
15960-413: The right. According to Flight International, the displays are easy to read while features such as the moving map display were considered to be "useful". The DA42 is also outfitted with a sophisticated three-axis Garmin -built GFC 700 autopilot and GWX 70 weather radar . The flight performance of the DA42 is largely favourable, having been designed to incorporate not only high levels of performance but
16100-496: The same house. Speculators that bought CDS protection were betting significant mortgage security defaults would occur, while the sellers (such as AIG ) bet they would not. An unlimited amount could be wagered on the same housing-related securities, provided buyers and sellers of the CDS could be found. When massive defaults occurred on underlying mortgage securities, companies like AIG that were selling CDS were unable to perform their side of
16240-456: The seats have been designed for crashworthiness and are complete with automotive-style three-point seat belts; while the seats themselves are fixed in position, the position of the rudder-pedals is adjustable. The front pair of seats are accessed via a front-hinged canopy while a top-hinged door located on the left side provides access to the rear seats. The pilots are housed under a sizable canopy which provides generous external visibility, save for
16380-518: The stimulus measures such as quantitative easing (pumping money into the system) and holding down central bank wholesale lending interest rate should be withdrawn as soon as economies recover enough to "chart a path to sustainable growth ". The distribution of household incomes in the United States became more unequal during the post-2008 economic recovery . Income inequality in the United States grew from 2005 to 2012 in more than two thirds of metropolitan areas. Median household wealth fell 35% in
16520-649: The stock market meant that household debt relative to assets held broadly stable, which masked households' growing exposure to a sharp fall in asset prices. When house prices declined, ushering in the global financial crisis, many households saw their wealth shrink relative to their debt, and, with less income and more unemployment, found it harder to meet mortgage payments. By the end of 2011, real house prices had fallen from their peak by about 41% in Ireland, 29% in Iceland, 23% in Spain and
16660-542: The system. Policy-makers, regulators and supervisors, in some advanced countries, did not adequately appreciate and address the risks building up in financial markets, keep pace with financial innovation, or take into account the systemic ramifications of domestic regulatory actions. Federal Reserve Chair Ben Bernanke testified in September 2010 before the FCIC regarding the causes of the crisis. He wrote that there were shocks or triggers (i.e., particular events that touched off
16800-601: The term "airplane" is used for powered fixed-wing aircraft. In the United Kingdom and Ireland and most of the Commonwealth , the term "aeroplane" ( / ˈ ɛər ə p l eɪ n / ) is usually applied to these aircraft. Many stories from antiquity involve flight, such as the Greek legend of Icarus and Daedalus , and the Vimana in ancient Indian epics . Around 400 BC in Greece , Archytas
16940-533: The time, the International Monetary Fund (IMF) concluded that it was the most severe economic and financial meltdown since the Great Depression . The causes of the Great Recession include a combination of vulnerabilities that developed in the financial system, along with a series of triggering events that began with the bursting of the United States housing bubble in 2005–2012. When housing prices fell and homeowners began to abandon their mortgages,
17080-483: The time; Aerospace publication Flying Magazine referred to Diamond's choice to develop a twin-engined aircraft for general aviation use as "the emergence of an all-new light-piston twin in this class something of a surprise." During April 2004, the DA42 Twin Star received certification from the European Aviation Safety Agency (EASA) under the latter's newly-introduced Part procedures. In July 2005,
17220-492: The top investment banks during an April 2004 meeting with bank leaders. These banks increased their risk-taking shortly thereafter, significantly increasing their purchases and securitization of lower-quality mortgages, thus encouraging additional subprime and Alt-A lending by mortgage companies. This action by its investment bank competitors also resulted in Fannie Mae and Freddie Mac taking on more risk. The financial crisis and
17360-408: The turbine to that passing through is called the by-pass ratio . They represent a compromise between turbojet (with no bypass) and turboprop forms of aircraft propulsion (primarily powered with bypass air). Subsonic aircraft, such as airliners, employ high by-pass jet engines for fuel efficiency. Supersonic aircraft , such as jet fighters, use low-bypass turbofans. However at supersonic speeds,
17500-474: The use of a large fixed sunscreen. Additionally, separate baggage compartments, which are accessible via external hatches, are contained within internal space in the aircraft's nose. Both the avionics and principal flight controls of the DA42 have been designed to be user-friendly and to reduce pilot workload. A Garmin G1000 glass cockpit serves as the centrepiece of the aircraft's integrated digital avionics, using
17640-404: The value of mortgage-backed securities held by investment banks declined in 2007–2008, causing several to collapse or be bailed out in September 2008. This 2007–2008 phase was called the subprime mortgage crisis . The combination of banks being unable to provide funds to businesses, and homeowners paying down debt rather than borrowing and spending, resulted in the Great Recession that began in
17780-515: The value of both stock markets and housing prices, fell $ 11.5 trillion (17.3%) and did not regain its pre-recession level of $ 66.4 trillion until Q3 2012. The number of persons with jobs (total non-farm payrolls) fell 8.6 million (6.2%) and did not regain the pre-recession level of 138.3 million until May 2014. The unemployment rate peaked at 10.0% in October 2009 and did not return to its pre-recession level of 4.7% until May 2016. A key dynamic slowing
17920-408: The wings and the fuselage. When complete, a plane is rigorously inspected to search for imperfections and defects. After approval by inspectors, the plane is put through a series of flight tests to assure that all systems are working correctly and that the plane handles properly. To meet a particular customer need, the airplane may be customised using components or packages of components provided by
18060-477: The word airplane , like aeroplane , derives from the French aéroplane , which comes from the Greek ἀήρ ( aēr ), "air" and either Latin planus , "level", or Greek πλάνος ( planos ), "wandering". " Aéroplane " originally referred just to the wing, as it is a plane moving through the air. In an example of synecdoche , the word for the wing came to refer to the entire aircraft. In the United States and Canada,
18200-453: The word "recession" exist: one sense referring definitively to "a period of reduced economic activity" and ongoing hardship; and the more allegoric interpretation used in economics , which is defined operationally , referring specifically to the contraction phase of a business cycle , with two or more consecutive quarters of GDP contraction (negative GDP growth rate) and typically used to influence abrupt changes in monetary policy. Under
18340-660: The world, especially in the United States , France, the United Kingdom , Spain , the Netherlands, Australia, the United Arab Emirates, New Zealand , Ireland , Poland , South Africa , Greece , Bulgaria , Croatia , Norway , Singapore , South Korea , Sweden , Finland , Argentina , the Baltic states , India , Romania , Ukraine and China . U.S. Federal Reserve Chairman Alan Greenspan said in mid-2005 that "at
18480-507: The world; whereas most of the world's developed economies , particularly in North America, South America and Europe, fell into a severe, sustained recession, many more recently developing economies suffered far less impact, particularly China , India and Indonesia , whose economies grew substantially during this period. Similarly, Oceania suffered minimal impact , in part due to its proximity to Asian markets. Two interpretations of
18620-403: Was deliberately de-rated in order to produce the same power 101 kW (135 hp) and torque 409 N⋅m (302 lbf⋅ft) as the earlier 1.7 L. engine. In late 2007, Diamond announced it would begin building and installing its own aerodiesels, through a subsidiary, Austro Engine GmbH, in collaboration with other partners that included Mercedes-Benz . The continued use of Thielert engines on
18760-647: Was delivered to a customer in Sweden. On 9 April 2010, the DA42 NG received FAA certification, clearing the way for sales to resume to North American customers. By March 2012, the DA42 had become the major income driver at Diamond Aircraft. Company CEO Christian Dries indicated that the market focus of the company had been changed by the Great Recession of 2008–2010 which had led the company to transition to derive two-thirds of its revenue from military and government contracts, primarily for manned and unmanned surveillance aircraft ,
18900-475: Was flown and landed without ground support in 2015. In July 2018, the Rossiyskaya Gazeta announced a UAV version, DA-42B, armed with the 9M120 Ataka antitank missile. The Diamond DA42 Twin Star is a twin-engined low-wing cantilever monoplane , commonly used as a general aviation aircraft for touring and training purposes. It is equipped with a retractable tricycle landing gear arrangement and uses
19040-453: Was paid out to major global financial institutions on behalf of AIG. While this money was legally owed to the banks by AIG (under agreements made via credit default swaps purchased from AIG by the institutions), a number of Congressmen and media members expressed outrage that taxpayer money was used to bail out banks. Economist Gary Gorton wrote in May 2009 Unlike the historical banking panics of
19180-409: Was reputed to have designed and built the first artificial, self-propelled flying device, a bird-shaped model propelled by a jet of what was probably steam, said to have flown some 200 m (660 ft). This machine may have been suspended for its flight. Some of the earliest recorded attempts with gliders were those by the 9th-century Andalusian and Arabic-language poet Abbas ibn Firnas and
19320-519: Was tested with overhead rails to prevent it from rising. The test showed that it had enough lift to take off. The craft was uncontrollable and it is presumed that Maxim realized this because he subsequently abandoned work on it. Between 1867 and 1896, the German pioneer of human aviation Otto Lilienthal developed heavier-than-air flight. He was the first person to make well-documented, repeated, successful gliding flights. Lilienthal's work led to him developing
19460-526: Was the German Heinkel He 178 , which was tested in 1939. In 1943, the Messerschmitt Me 262 , the first operational jet fighter aircraft, went into service in the German Luftwaffe . The first jet airliner , the de Havilland Comet , was introduced in 1952. The Boeing 707 , the first widely successful commercial jet, was in commercial service for more than 50 years, from 1958 to 2010. The Boeing 747
19600-518: Was the world's biggest passenger aircraft from 1970 until it was surpassed by the Airbus A380 in 2005. Supersonic airliner flights , including those of the Concorde , have been limited to over-water flight at supersonic speed because of their sonic boom , which is prohibited over most populated land areas. The high cost of operation per passenger-mile and a deadly crash in 2000 induced the operators of
