Mean Sea Level
A mean is a quantity representing the "center" of a collection of numbers and is intermediate to the extreme values of the set of numbers. There are several kinds of means (or "measures of central tendency") in mathematics, especially in statistics. Each attempts to summarize or typify a given group of data, illustrating the magnitude and sign of the data set. Which of these measures is most illuminating depends on what is being measured, and on context and purpose. The ''arithmetic mean'', also known as "arithmetic average", is the sum of the values divided by the number of values. The arithmetic mean of a set of numbers ''x''1, ''x''2, ..., x''n'' is typically denoted using an overhead bar, \bar. If the numbers are from observing a sample of a larger group, the arithmetic mean is termed the '' sample mean'' (\bar) to distinguish it from the group mean (or expected value) of the underlying distribution, denoted \mu or \mu_x. Outside probability and statistics, a wide rang ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Multnomah County Poor Farm
The Multnomah County Poor Farm is a former poor farm located in Troutdale, Oregon, United States. Established in 1911, the building and its surrounding grounds operated as a poor farm housing the ill and indigent populations in the Portland metropolitan area at the beginning of the twentieth century, after the closure of a poor farm in the city's West Hills. Over the course of the century, the farm would come to be used as a nursing home before becoming abandoned in the 1980s. Since 1990, the site is operated as an entertainment and lodging complex under the name McMenamins Edgefield, one of several historic properties owned, restored, and operated by the McMenamins enterprise. The property is listed on the National Register of Historic Places. History Establishment In 1854 the territorial legislature gave the counties the responsibility of caring for the poor. 1868 saw the first pauper's farm open in the west hills of Portland.

Cessna 421 Golden Eagle
The Cessna 421 Golden Eagle is an American six or seven seat twin-engined light transport aircraft, developed in the 1960s by Cessna as a pressurized version of the earlier Cessna 411. Development The Cessna 421 was first produced in May 1967, the 1968 model year. It had "Stabila-Tip" fuel tanks on the wingtips (like the Cessna 310). Its electro-mechanical landing gear are similar to that of the 310. It was an immediate hit, selling 200 planes in its first year. The very next year, 1969, the design was refined, with a three-inch stretch of the fuselage, five more gallons of fuel capacity, and a 40-pound increase in gross weight. The plane was redesignated the Cessna 421A. In 1971, the design was again improved. Both empty and gross weight increased, the wingspan was increased by two feet, raising the service ceiling by 5,000 feet. The nose was stretched two feet to accommodate a larger nose baggage section. This new plane is designated the Cessna 421B. In 1975, the plan ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Robinson R22
The Robinson R22 is a two-seat, two-bladed, single-engined, light utility helicopter manufactured by Robinson Helicopter Company. It was designed in 1973 by Frank D. Robinson, and has been in production since 1979. Development The majority of flight testing was performed at Zamperini Field in Torrance, California. Flight testing and certification were performed in the late 1970s by test pilot Joseph John "Tym" Tymczyszyn, and the R22 received FAA certification in March 1979. Due to relatively low acquisition and operating costs, the R22 has been popular as a primary rotorcraft trainer around the world, entry-level personal helicopter, and as a livestock-management tool on large ranches in North America and cattle stations in Australia. The R22 has a very low-inertia rotor system Greenspun, Philip.2005 Robinson R22 - owner's review" March 2010.

Douglas DC-8
The Douglas DC-8 (sometimes McDonnell Douglas DC-8) is an early long-range Narrow-body aircraft, narrow-body jetliner designed and produced by the American Douglas Aircraft Company. Work began in 1952 towards the United States Air Force's (USAF) requirement for a jet-powered aerial refueling, aerial refueling tanker. After losing the USAF's tanker competition to the rival Boeing KC-135 Stratotanker in May 1954, Douglas announced in June 1955 its derived jetliner project marketed to civil operators. In October 1955, Pan American World Airways, Pan Am made the first order along with the competing Boeing 707, and many other airlines soon followed. The first DC-8 was rolled out in Long Beach Airport on April 9, 1958, and flew for the first time on May 30. Following Federal Aviation Administration (FAA) certification in August 1959, the DC-8 entered service with Delta Air Lines on September 18.

Drop Tank
In aviation, a drop tank (external tank, wing tank or belly tank) is used to describe auxiliary fuel tanks externally carried by aircraft. A drop tank is expendable and often capable of being jettisoned. External tanks are commonplace on modern military aircraft and occasionally found in Civilian aircraft, civilian ones, although the latter are less likely to be discarded except in an emergency. Overview The primary disadvantage with drop tanks is that they impose a drag penalty on the aircraft. External fuel tanks will also increase the moment of inertia, thereby reducing Flight dynamics, roll rates for Air combat manoeuvring, air maneuvers. Some of the drop tank's fuel is used to overcome the added drag and weight of the tank. Drag in this sense varies with the square of the aircraft's speed. The use of drop tanks also reduces the number of external hardpoints available for weapons, reduces the weapon-carrying capacity and increases the aircraft's radar signature. Usually th ...

Quaker City Airways
Supplemental air carriers, until 1955 known as irregular air carriers, and until 1946 as nonscheduled air carriers or nonskeds, were a type of United States airline from 1944 to 1978, regulated by the Civil Aeronautics Board (CAB), a now-defunct federal agency that then tightly controlled almost all US commercial air transport. From 1964 onward, these airlines were just charter carriers, but until 1964 they had limited but flexible ability to offer scheduled service, making them hybrids. In some ways they were the opposite of what the law then said an airline should be. Airlines then required CAB certification, but over 150 nonskeds exploited a loophole to simply start operating. The CAB determined where certificated carriers flew and what they charged. For the most part, irregular carriers flew where they wanted and charged what they wanted. CAB-certificated passenger carriers almost never died (the CAB preferentially awarded desirable routes to weak scheduled passenger carriers a ...
