Denver the City and County of Denver, is the capital and most populous municipality of the U. S. state of Colorado. Denver is located in the South Platte River Valley on the western edge of the High Plains just east of the Front Range of the Rocky Mountains; the Denver downtown district is east of the confluence of Cherry Creek with the South Platte River 12 mi east of the foothills of the Rocky Mountains. Denver is named after James W. Denver, a governor of the Kansas Territory, it is nicknamed the Mile High City because its official elevation is one mile above sea level; the 105th meridian west of Greenwich, the longitudinal reference for the Mountain Time Zone, passes directly through Denver Union Station. Denver is ranked as a Beta world city by World Cities Research Network. With an estimated population of 704,621 in 2017, Denver is the 19th-most populous U. S. city, with a 17.41% increase since the 2010 United States Census, it has been one of the fastest-growing major cities in the United States.
The 10-county Denver-Aurora-Lakewood, CO Metropolitan Statistical Area had an estimated 2017 population of 2,888,227 and is the 19th most populous U. S. metropolitan statistical area. The 12-city Denver-Aurora, CO Combined Statistical Area had an estimated 2017 population of 3,515,374 and is the 15th most populous U. S. metropolitan area. Denver is the most populous city of the 18-county Front Range Urban Corridor, an oblong urban region stretching across two states with an estimated 2017 population of 4,895,589. Denver is the most populous city within a 500-mile radius and the second-most populous city in the Mountain West after Phoenix, Arizona. In 2016, Denver was named the best place to live in the United States by U. S. News & World Report. In the summer of 1858, during the Pike's Peak Gold Rush, a group of gold prospectors from Lawrence, Kansas established Montana City as a mining town on the banks of the South Platte River in what was western Kansas Territory; this was the first historical settlement in what was to become the city of Denver.
The site faded however, by the summer of 1859 it was abandoned in favor of Auraria and St. Charles City. On November 22, 1858, General William Larimer and Captain Jonathan Cox, both land speculators from eastern Kansas Territory, placed cottonwood logs to stake a claim on the bluff overlooking the confluence of the South Platte River and Cherry Creek, across the creek from the existing mining settlement of Auraria, on the site of the existing townsite of St. Charles. Larimer named the townsite Denver City to curry favor with Kansas Territorial Governor James W. Denver. Larimer hoped the town's name would help make it the county seat of Arapaho County but, unbeknownst to him, Governor Denver had resigned from office; the location was accessible to existing trails and was across the South Platte River from the site of seasonal encampments of the Cheyenne and Arapaho. The site of these first towns is now the site of Confluence Park near downtown Denver. Larimer, along with associates in the St. Charles City Land Company, sold parcels in the town to merchants and miners, with the intention of creating a major city that would cater to new immigrants.
Denver City was a frontier town, with an economy based on servicing local miners with gambling, saloons and goods trading. In the early years, land parcels were traded for grubstakes or gambled away by miners in Auraria. In May 1859, Denver City residents donated 53 lots to the Leavenworth & Pike's Peak Express in order to secure the region's first overland wagon route. Offering daily service for "passengers, mail and gold", the Express reached Denver on a trail that trimmed westward travel time from twelve days to six. In 1863, Western Union furthered Denver's dominance of the region by choosing the city for its regional terminus; the Colorado Territory was created on February 28, 1861, Arapahoe County was formed on November 1, 1861, Denver City was incorporated on November 7, 1861. Denver City served as the Arapahoe County Seat from 1861 until consolidation in 1902. In 1867, Denver City became the acting territorial capital, in 1881 was chosen as the permanent state capital in a statewide ballot.
With its newfound importance, Denver City shortened its name to Denver. On August 1, 1876, Colorado was admitted to the Union. Although by the close of the 1860s, Denver residents could look with pride at their success establishing a vibrant supply and service center, the decision to route the nation's first transcontinental railroad through Cheyenne, rather than Denver, threatened the prosperity of the young town. A daunting 100 miles away, citizens mobilized to build a railroad to connect Denver to the transcontinental railroad. Spearheaded by visionary leaders including Territorial Governor John Evans, David Moffat, Walter Cheesman, fundraising began. Within three days, $300,000 had been raised, citizens were optimistic. Fundraising stalled before enough was raised, forcing these visionary leaders to take control of the debt-ridden railroad. Despite challenges, on June 24, 1870, citizens cheered as the Denver Pacific completed the link to the transcontinental railroad, ushering in a new age of prosperity for Denver.
Linked to the rest of the nation by rail, Denver prospered as a service and supply center. The young city grew during these years, attracting millionaires with their mansions, as well as the poverty and crime of a growing city. Denver citizens were proud when the rich chose Denver and were thrilled when Horace Tabor, the Leadville mining millionaire, built an impressive business block at 16th and Larimer as well as the el
Oakland is the largest city and the county seat of Alameda County, United States. A major West Coast port city, Oakland is the largest city in the East Bay region of the San Francisco Bay Area, the third largest city overall in the San Francisco Bay Area, the eighth most populated city in California, the 45th largest city in the United States. With a population of 425,195 as of 2017, it serves as a trade center for the San Francisco Bay Area. An act to incorporate the city was passed on May 4, 1852, incorporation was approved on March 25, 1854, which made Oakland a city. Oakland is a charter city. Oakland's territory covers what was once a mosaic of California coastal terrace prairie, oak woodland, north coastal scrub, its land served as a rich resource when its hillside oak and redwood timber were logged to build San Francisco. Oakland's fertile flatland soils helped. In the late 1860s, Oakland was selected as the western terminal of the Transcontinental Railroad. Following the 1906 San Francisco earthquake, many San Francisco citizens moved to Oakland, enlarging the city's population, increasing its housing stock and improving its infrastructure.
It continued to grow in the 20th century with its busy port, a thriving automobile manufacturing industry. The earliest known inhabitants were the Huchiun Indians; the Huchiun belonged to a linguistic grouping called the Ohlone. In Oakland, they were concentrated around Lake Merritt and Temescal Creek, a stream that enters the San Francisco Bay at Emeryville. In 1772, the area that became Oakland was colonized, with the rest of California, by Spanish settlers for the King of Spain. In the early 19th century, the Spanish crown granted the East Bay area to Luis María Peralta for his Rancho San Antonio; the grant was confirmed by the successor Mexican republic upon its independence from Spain. Upon his death in 1842, Peralta divided his land among his four sons. Most of Oakland fell within the shares given to Antonio Vicente; the portion of the parcel, now Oakland was called Encinal—Spanish for "oak grove"—due to the large oak forest that covered the area, which led to the city's name. During the 1850s—just as gold was discovered in California—Oakland started growing and developing because land was becoming too expensive in San Francisco.
The Chinese were struggling financially, as a result of the First Opium War, the Second Opium War, the Taiping Rebellion, so they began migrating to Oakland in an effort to provide for their families in China. However, the Chinese struggled to settle because they were discriminated against by the white community and their living quarters were burned down on several occasions; the majority of the Chinese migrants lived in unhealthy conditions in China and they had diseases, so plague spread into San Francisco though the Chinese were inspected for diseases upon their arrival to San Francisco. In 1851, three men—Horace Carpentier, Edson Adams, Andrew Moon—began developing what is now downtown Oakland. In 1852, the Town of Oakland became incorporated by the state legislature. During this time, Oakland had 75-100 inhabitants, two hotels, a wharf, two warehouses, only cattle trails. Two years on March 25, 1854, Oakland re-incorporated as the City of Oakland, with Horace Carpentier elected the first mayor, though a scandal ended his mayorship in less than a year.
The city and its environs grew with the railroads, becoming a major rail terminal in the late 1860s and 1870s. In 1868, the Central Pacific constructed the Oakland Long Wharf at Oakland Point, the site of today's Port of Oakland. A number of horsecar and cable car lines were constructed in Oakland during the latter half of the 19th century; the first electric streetcar set out from Oakland to Berkeley in 1891, other lines were converted and added over the course of the 1890s. The various streetcar companies operating in Oakland were acquired by Francis "Borax" Smith and consolidated into what became known as the Key System, the predecessor of today's publicly owned AC Transit. Oakland was one of the worst affected cities in California, impacted by the plague epidemic. Quarantine measures were set in place at the Oakland ports requiring the authorities at the port to inspect the arriving vessels for the presence of infected rats. Quarantine authorities at these ports inspected over a thousand vessels per year for plague and yellow fever.
By 1908, over 5,000 people were detained in quarantine. Hunters were sent to poison the affected areas in Oakland and shoot the squirrels, but the eradication work was limited in its range because the State Board of Health and the United States Public Health Service were only allotted about $60,000 a year to eradicate the disease. During this period Oakland did not have sufficient health facilities, so some of the infected patients were treated at home; the State Board of Health along with Oakland advised physicians to promptly report any cases of infected patients. Yet, in 1919 it still resulted in a small epidemic of Pneumonic plague which killed a dozen people in Oakland; this started when a man killed a squirrel. After eating the squirrel, he fell ill four days and another household member contracted the plague; this in turn was passed on either indirectly to about a dozen others. The officials in Oakland acted by issuing death certificates to monitor the spread of plague. At the time of incorporation in 1852, Oaklan
Pilot certification in the United States
Pilot certification in the United States is required for an individual to act as a pilot-in-command of an aircraft. It is regulated by the Federal Aviation Administration, a branch of the U. S. Department of Transportation. A pilot is certified under the authority of Parts 61, under 141 of Title 14 of the Code of Federal Regulations known as the Federal Aviation Regulations, or under part 107 rules for drone operation. An FAA-issued pilot certificate is evidence that an individual is duly authorized to exercise piloting privileges; the pilot certificate is one of several kinds of airman certificates issued by the FAA. A pilot is certificated to fly aircraft at one or more named privilege levels and, at each privilege level, rated to fly aircraft of specific categories. Privilege levels of pilot certificates are, in order of increasing privilege: Student Pilot: an individual, learning to fly under the tutelage of a flight instructor and, permitted to fly alone under specific, limited circumstances Sport Pilot: an individual, authorized to fly only Light-sport Aircraft Remote Pilot: an individual who may fly small Unmanned Aerial Vehicles for compensation or hire Recreational Pilot: an individual who may fly aircraft of up to 180 horsepower and 4 seats in the daytime for pleasure only Private Pilot: an individual who may fly for pleasure or personal business without accepting compensation Commercial Pilot: an individual who may, with some restrictions, fly for compensation or hire Airline Transport Pilot: an individual authorized to act as pilot for a scheduled airline.
Pilots can be rated in these aircraft categories: Airplane Rotorcraft Glider Lighter than air Powered lift Powered parachute Weight-shift controlMost aircraft categories are further broken down into classes. If a category is so divided, a pilot must hold a class rating to operate an aircraft in that class: The Airplane category is divided into single-engine land, multi-engine land, single-engine sea, multi-engine sea classes The Rotorcraft category is divided into helicopter and gyroplane classes The Lighter-than-air category is divided into airship and balloon classes The Powered parachute category is divided into powered parachute land and powered parachute sea The Weight-shift-control category is divided into weight-shift-control land and weight-shift-control seaA student pilot certificate does not list category or class ratings but is instead endorsed by a flight instructor to confer privileges in specific makes and models of aircraft. A type rating is required in a specific make and model of aircraft if the aircraft weighs more than 12,500 lb at takeoff or is powered by one or more turbojet engines.
The Boeing 747, Beechcraft Super King Air 350, the Hawker Hunter are examples of aircraft that require type ratings. To operate under instrument flight rules, a pilot can separately add an instrument rating to a private or commercial certificate. An airline transport pilot implicitly holds an instrument rating, so the instrument rating does not appear on an ATP certificate; the FAA issues instrument ratings separately for airplane and powered lift categories and the helicopter class. Glider and airship pilots may operate under Instrument Flight Rules under certain circumstances. An individual may hold only one pilot certificate at one time. For example, an Airline Transport Pilot certificate holder may be permitted to exercise ATP privileges when flying multi-engine land airplanes, but only Commercial Pilot privileges when flying single-engine land airplanes and gliders. A Commercial Pilot holder with a glider rating may have only Private Pilot privileges for single-engine land airplanes; the FAA may impose limitations on a pilot certificate if, during training or the practical test, the pilot does not demonstrate all skills necessary to exercise all privileges of a privilege level, class or type rating.
For example, a holder of a DC-3 type rating who does not demonstrate instrument flying skills during the practical test would be assigned a limitation reading, "DC-3". To obtain a certificate or add a rating, a pilot has to undergo a course of training with a Certificated Flight Instructor under 14CFR61 or enroll at an approved course at a 14CFR141 approved flight school; the applicant must accumulate and log specific aeronautical experience, pass a three-part examination: a knowledge test, an oral test, a practical test carried out by either an FAA inspector or a Designated Pilot Examiner. Another form of authorization is a logbook endorsement from a flight instructor that establishes that the certificate holder has received training in specific skill areas that do not warrant a full test, such as the ability to fly a tailwheel-equipped, high-performance, complex, or pressurized airplane. Pilot certificates do not expire, although they may be suspended or revoked by the FAA. However, a pilot must maintain currency — recent flight experience, relevant to the flight being undertaken.
To remain current, every pilot has to undergo a flight review with an instructor every 24 calendar months unless she or he gains a new pilot certificate or rating in that time or satisfies the flight review requirement using an alternate approved means. For most types of certificate, she or he must undergo a medical examination at intervals ra
The United States of America known as the United States or America, is a country composed of 50 states, a federal district, five major self-governing territories, various possessions. At 3.8 million square miles, the United States is the world's third or fourth largest country by total area and is smaller than the entire continent of Europe's 3.9 million square miles. With a population of over 327 million people, the U. S. is the third most populous country. The capital is Washington, D. C. and the largest city by population is New York City. Forty-eight states and the capital's federal district are contiguous in North America between Canada and Mexico; the State of Alaska is in the northwest corner of North America, bordered by Canada to the east and across the Bering Strait from Russia to the west. The State of Hawaii is an archipelago in the mid-Pacific Ocean; the U. S. territories are scattered about the Pacific Ocean and the Caribbean Sea, stretching across nine official time zones. The diverse geography and wildlife of the United States make it one of the world's 17 megadiverse countries.
Paleo-Indians migrated from Siberia to the North American mainland at least 12,000 years ago. European colonization began in the 16th century; the United States emerged from the thirteen British colonies established along the East Coast. Numerous disputes between Great Britain and the colonies following the French and Indian War led to the American Revolution, which began in 1775, the subsequent Declaration of Independence in 1776; the war ended in 1783 with the United States becoming the first country to gain independence from a European power. The current constitution was adopted in 1788, with the first ten amendments, collectively named the Bill of Rights, being ratified in 1791 to guarantee many fundamental civil liberties; the United States embarked on a vigorous expansion across North America throughout the 19th century, acquiring new territories, displacing Native American tribes, admitting new states until it spanned the continent by 1848. During the second half of the 19th century, the Civil War led to the abolition of slavery.
By the end of the century, the United States had extended into the Pacific Ocean, its economy, driven in large part by the Industrial Revolution, began to soar. The Spanish–American War and World War I confirmed the country's status as a global military power; the United States emerged from World War II as a global superpower, the first country to develop nuclear weapons, the only country to use them in warfare, a permanent member of the United Nations Security Council. Sweeping civil rights legislation, notably the Civil Rights Act of 1964, the Voting Rights Act of 1965 and the Fair Housing Act of 1968, outlawed discrimination based on race or color. During the Cold War, the United States and the Soviet Union competed in the Space Race, culminating with the 1969 U. S. Moon landing; the end of the Cold War and the collapse of the Soviet Union in 1991 left the United States as the world's sole superpower. The United States is the world's oldest surviving federation, it is a representative democracy.
The United States is a founding member of the United Nations, World Bank, International Monetary Fund, Organization of American States, other international organizations. The United States is a developed country, with the world's largest economy by nominal GDP and second-largest economy by PPP, accounting for a quarter of global GDP; the U. S. economy is post-industrial, characterized by the dominance of services and knowledge-based activities, although the manufacturing sector remains the second-largest in the world. The United States is the world's largest importer and the second largest exporter of goods, by value. Although its population is only 4.3% of the world total, the U. S. holds 31% of the total wealth in the world, the largest share of global wealth concentrated in a single country. Despite wide income and wealth disparities, the United States continues to rank high in measures of socioeconomic performance, including average wage, human development, per capita GDP, worker productivity.
The United States is the foremost military power in the world, making up a third of global military spending, is a leading political and scientific force internationally. In 1507, the German cartographer Martin Waldseemüller produced a world map on which he named the lands of the Western Hemisphere America in honor of the Italian explorer and cartographer Amerigo Vespucci; the first documentary evidence of the phrase "United States of America" is from a letter dated January 2, 1776, written by Stephen Moylan, Esq. to George Washington's aide-de-camp and Muster-Master General of the Continental Army, Lt. Col. Joseph Reed. Moylan expressed his wish to go "with full and ample powers from the United States of America to Spain" to seek assistance in the revolutionary war effort; the first known publication of the phrase "United States of America" was in an anonymous essay in The Virginia Gazette newspaper in Williamsburg, Virginia, on April 6, 1776. The second draft of the Articles of Confederation, prepared by John Dickinson and completed by June 17, 1776, at the latest, declared "The name of this Confederation shall be the'United States of America'".
The final version of the Articles sent to the states for ratification in late 1777 contains the sentence "The Stile of this Confederacy shall be'The United States of America'". In June 1776, Thomas Jefferson wrote the phrase "UNITED STATES OF AMERICA" in all capitalized letters in the headline of his "original Rough draught" of the Declaration of Independence; this draft of the document did not surface unti
Phoenix is the capital and most populous city of Arizona, with 1,626,000 people. It is the fifth most populous city in the United States, the most populous American state capital, the only state capital with a population of more than one million residents. Phoenix is the anchor of the Phoenix metropolitan area known as the Valley of the Sun, which in turn is part of the Salt River Valley; the metropolitan area is the 11th largest by population in the United States, with 4.73 million people as of 2017. Phoenix is the seat of Maricopa County and the largest city in the state at 517.9 square miles, more than twice the size of Tucson and one of the largest cities in the United States. Phoenix was settled in 1867 as an agricultural community near the confluence of the Salt and Gila Rivers and was incorporated as a city in 1881, it became the capital of Arizona Territory in 1889. It has a hot desert climate. Despite this, its canal system led to a thriving farming community with the original settler's crops remaining important parts of the Phoenix economy for decades, such as alfalfa, cotton and hay.
Cotton, citrus and copper were known locally as the "Five C's" anchoring Phoenix's economy. These remained the driving forces of the city until after World War II, when high-tech companies began to move into the valley and air conditioning made Phoenix's hot summers more bearable; the city averaged a four percent annual population growth rate over a 40-year period from the mid-1960s to the mid-2000s. This growth rate slowed during the Great Recession of 2007–09, has rebounded slowly. Phoenix is the cultural center of the state of Arizona; the Hohokam people occupied the Phoenix area for 2,000 years. They created 135 miles of irrigation canals, making the desert land arable, paths of these canals were used for the Arizona Canal, Central Arizona Project Canal, the Hayden-Rhodes Aqueduct, they carried out extensive trade with the nearby Ancient Puebloans and Sinagua, as well as with the more distant Mesoamerican civilizations. It is believed that periods of drought and severe floods between 1300 and 1450 led to the Hohokam civilization's abandonment of the area.
After the departure of the Hohokam, groups of Akimel O'odham, Tohono O'odham, Maricopa tribes began to use the area, as well as segments of the Yavapai and Apache. The O'odham were offshoots of the Sobaipuri tribe, who in turn were thought to be the descendants of the Hohokam; the Akimel O'odham were the major group in the area and lived in small villages, with well-defined irrigation systems that spread over the entire Gila River Valley, from Florence in the east to the Estrellas in the west. Their crops included corn and squash for food, while cotton and tobacco were cultivated, they banded together with the Maricopa for protection against incursions by the Yuma and Apache tribes. The Maricopa are part of the larger Yuma people; the Tohono O'odham lived in the region, as well, but their main concentration was to the south and stretched all the way to the Mexican border. The O'odham lived in small settlements as seasonal farmers who took advantage of the rains, rather than the large-scale irrigation of the Akimel.
They grew crops such as sweet corn, tapery beans, lentils, sugar cane, melons, as well as taking advantage of native plants such as saguaro fruits, cholla buds, mesquite tree beans, mesquite candy. They hunted local game such as deer and javelina for meat; the Mexican–American War ended in 1848, Mexico ceded its northern zone to the United States, residents of that region became U. S. citizens. The Phoenix area became part of the New Mexico Territory. In 1863, the mining town of Wickenburg was the first to be established in Maricopa County, to the northwest of Phoenix. Maricopa County had not yet been incorporated; the Army created Fort McDowell on the Verde River in 1865 to forestall Indian uprisings. The fort established a camp on the south side of the Salt River by 1866, the first settlement in the valley after the decline of the Hohokam. Other nearby settlements merged to become the city of Tempe; the history of the city of Phoenix begins with Jack Swilling, a Confederate veteran of the Civil War.
He saw a potential for farming. He formed a small community that same year about four miles east of the city. Lord Darrell Duppa was one of the original settlers in Swilling's party, he suggested the name "Phoenix", as it described a city born from the ruins of a former civilization; the Board of Supervisors in Yavapai County recognized the new town on May 4, 1868, the first post office was established the following month with Swilling as the postmaster. On February 12, 1871, the territorial legislature created Maricopa County by dividing Yavapai County; the first election for county office was held in 1871. He ran unopposed; the town grew during the 1870s, President Ulysses S. Grant issued a land patent for the site of Phoenix on April 10, 1874. By 1875, the town had a telegraph office
Pilatus PC-6 Porter
The Pilatus PC-6 Porter is a single-engined STOL utility aircraft designed by Pilatus Aircraft of Switzerland. First flown in 1959, the PC-6 continues in production at Pilatus Flugzeugwerke in Stans, Switzerland, it has been built in both piston engine- and turboprop-powered versions and was produced under licence for a time by Fairchild Hiller in the United States. After around 600 deliveries in six decades, Pilatus will produce the last one in early 2019. On 4 May 1959, the first prototype, powered by a 254 kW piston engine, made its maiden flight. In early May 1961, the first Turbo Porter, powered by a Turbomeca Astazou II turboprop engine, performed its initial flight. In comparison to its earlier piston engine-powered incarnation, the Astazou II-equipped Turbo Porter had an increased gross capacity and top speed, as well as benefitting from the engine's automatic handling functions; these benefits came at the expense of higher fuel consumption. Both the piston and turbine-engine versions of the PC-6 became known for their Short Takeoff and Landing capabilities, requiring only a short takeoff run before being ready for rotation prior to taking off.
The initial turbine-powered models of the PC-6 were equipped with the Astazou II powerplant, however complaints of the reliability of this engine were made. Another early turboprop powerplant that became available for the PC-6 was the Garrett Air Research TPE 331; some operators such as Air America chose to retrofit their Astazou II-powered PC-6s with the TPE 331 engine in its place. In May 1996, the first PC-6 to be equipped with the Pratt & Whitney Canada PT6A engine performed its maiden flight. To offset rising labour and manufacturing costs in Switzerland, Pilatus distributed manufacturing work on the PC-6 to other countries. In 2013, Pilatus formed a joint venture with Beijing Tian Xing Jian Yu Science Co. Ltd. to locally manufacture the PC-6 and the newer Pilatus PC-12 in Chongqing, China. Global production of the PC-6 shall be transferred to the Chongqing facility. On 11 December 2014, the first Chinese-assembled PC-6 fuselage was completed. In 2014, the majority of PC-6s delivered that year were to Chinese customers.
By April 2016, around 20 PC-6s were in operation in the Chinese market. The Porter was manufactured under license by Fairchild Hiller in the United States. 100 of these licence-produced aircraft would be completed, being purchased by civil operators within the US. A number of Fairchild Hiller-built PC-6s were procured for military operations during the Vietnam War, it received the designation AU-23A Peacemaker for service with the U. S. Air Force; the Peacemaker was fitted with a side-firing 20mm XM-197 Gatling cannon, four wing pylons and a centre fuselage station for external ordnance. However, the AU-23A proved to be troublesome in service. All of them were returned to the continental U. S. and placed into storage after only a single year of operation. In 1979, a pair of UV-20s were assigned to the aviation detachment of the Berlin Brigade in Germany due to their suitability for operating within the restricted airspace. After nearly 600 deliveries in six decades including about 90 Fairchild-Hiller built and 425 PT6-powered, but only 52 in the last ten years, Pilatus will close the orderbook from summer 2018 and will roll off the last one in early 2019 while parts production will continue for at least 20 years.
The Pilatus PC-6 Porter is a Short Landing utility aircraft. The majority of aircraft are powered by a single Pratt & Whitney Canada PT6A turboprop engine, which drives a reversible, constant-speed, three-bladed HC-B3TN-3D Hartzell aluminium propeller via a reduction gearbox. Pilatus claims that it possesses unique STOL capabilities, capable of landing in places only otherwise accessible by rotorcraft, it is capable of being operated from unprepared rough airstrips, in remote areas, hot climates and at high altitudes in all-weather conditions. In particular, the undercarriage employed provides for high wing and propeller clearances, making the PC-6 less susceptible to damage than conventional nosewheel-type undercarriages. For further landing versatility, various types of landing gear may be optionally installed allowing it to operate from different types of terrain. Early models of the PC-6 were equipped with a full instrument panel as standard, were easy for unfamiliar pilots to intuit. Later-manufactured PC-6s are equipped with a Garmin G950 glass cockpit in place of analog instrumentation.
In addition to its flight functionality, the G950 system acts as a remote maintenance unit and electronic flight bag all in one. Two large 10.4-inch liquid-crystal displays are present, functioning as the Primary Flight Display for all key flight information and the Multi-function Display for system/mission management respectively. The cockpit has been designed for single pilot operations.
Anchorage is a unified home rule municipality in the U. S. state of Alaska. With an estimated 298,192 residents in 2016, it is Alaska's most populous city and contains more than 40 percent of the state's total population. All together, the Anchorage metropolitan area, which combines Anchorage with the neighboring Matanuska-Susitna Borough, had a population of 401,635 in 2016, which accounts for more than half of the state's population. At 1,706 square miles of land area, the city is the fourth largest city by land in the United States and larger than the smallest state, Rhode Island, at 1,212 square miles. Anchorage is in the south-central portion of Alaska, at the terminus of the Cook Inlet, on a peninsula formed by the Knik Arm to the north and the Turnagain Arm to the south; the city limits span 1,961.1 square miles which encompass the urban core, a joint military base, several outlying communities and all of Chugach State Park. Due to its location equidistant from New York City and Tokyo, Anchorage lies within 9 1⁄2 hours by air of nearly 90% of the industrialized world.
For this reason, the Anchorage International Airport is a common refueling stop for many international cargo flights and home to a major FedEx hub, which the company calls a "critical part" of its global network of services. Anchorage has won the All-America City Award four times: in 1956, 1965, 1984–85, 2002, by the National Civic League, it has been named by Kiplinger as the most tax-friendly city in the United States. Russian presence in south-central Alaska was well-established in the 19th century. In 1867, U. S. Secretary of State William H. Seward brokered a deal to purchase Alaska from Imperial Russia for $7.2 million, or about two cents an acre. His political rivals lampooned the deal as "Seward's folly," "Seward's icebox," and "Walrussia." In 1888, gold was discovered along Turnagain Arm. Alaska became an organized incorporated United States territory in 1912. Anchorage, unlike every other large town in Alaska south of the Brooks Range, was neither a fishing nor mining camp; the area surrounding Anchorage lacks significant economic metal minerals.
A number of Dena'ina settlements existed along Knik Arm for years. By 1911 the families of J. D. "Bud" Whitney and Jim St. Clair lived at the mouth of Ship Creek and were joined there by a young forest ranger, Jack Brown, his bride, Nellie, in 1912; the city grew from its happenstance choice as the site, in 1914, under the direction of Frederick Mears, of a railroad-construction port for the Alaska Engineering Commission. The area near the mouth of Ship Creek, where the railroad headquarters was located became a tent city. A townsite was mapped out on higher ground to the south of the tent city noted in the years since for its order and rigidity compared with other Alaska town sites. In 1915, territorial governor John Franklin Alexander Strong encouraged residents to change the city's name to one that had "more significance and local associations". In the summer of that year, residents held a vote to change the city's name. However, the territorial government declined to change the city's name.
