Light Aircraft
A light aircraft is an aircraft that has a maximum gross takeoff weight of or less.Crane, Dale: ''Dictionary of Aeronautical Terms, third edition'', page 308. Aviation Supplies & Academics, 1997. Light aircraft are used as utility aircraft commercially for passenger and freight transport, sightseeing, photography, and other roles, as well as personal use. Examples of aircraft that are at the maximum gross takeoff weight for this category include the de Havilland Canada DHC-6 Twin Otter and Beechcraft B200 Super King Air. Uses Uses include aerial surveying, such as monitoring pipelines, light cargo operations, such as "feeding" cargo hubs, and passenger operations. Light aircraft are used for marketing purposes, such as banner towing and skywriting, and flight instruction. The majority of personal aircraft are light aircraft, the most popular in history being the Cessna 172, and most popular in modern history being the Cirrus SR22 and Robinson R44. Larger light aircraft, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Aircraft Owners And Pilots Association
The Aircraft Owners and Pilots Association (AOPA) is a Frederick, Maryland-based American non-profit political organization that advocates for general aviation. AOPA's membership consists mainly of general aviation pilots in the United States. AOPA exists to serve the interests of its members as aircraft owners and pilots and to promote the economy, safety, utility, and popularity of flight in general aviation aircraft. With 384,915 members in 2012, AOPA is the largest aviation association in the world, although it had decreased in membership from 414,224 in 2010, a loss of 7% in two years. AOPA is affiliated with other similar organizations in other countries through membership in the International Council of Aircraft Owner and Pilot Associations (IAOPA). In 2015, AOPA was inducted into the International Air & Space Hall of Fame at the San Diego Air & Space Museum. History The organization started at Wings Field in Blue Bell, Pennsylvania. On 24 April 1932, The Philadelp ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Aircraft Designers
An aircraft is a vehicle that is able to fly by gaining support from the air. It counters the force of gravity by using either static lift or by using the dynamic lift of an airfoil, or in a few cases the downward thrust from jet engines. Common examples of aircraft include airplanes, helicopters, airships (including blimps), gliders, paramotors, and hot air balloons. The human activity that surrounds aircraft is called ''aviation''. The science of aviation, including designing and building aircraft, is called '' aeronautics.'' Crewed aircraft are flown by an onboard pilot, but unmanned aerial vehicles may be remotely controlled or self-controlled by onboard computers. Aircraft may be classified by different criteria, such as lift type, aircraft propulsion, usage and others. History Flying model craft and stories of manned flight go back many centuries; however, the first manned ascent — and safe descent — in modern times took place by larger hot-air ...

Year Of Birth Missing (living People)
A year or annus is the orbital period of a planetary body, for example, the Earth, moving in its orbit around the Sun. Due to the Earth's axial tilt, the course of a year sees the passing of the seasons, marked by change in weather, the hours of daylight, and, consequently, vegetation and soil fertility. In temperate and subpolar regions around the planet, four seasons are generally recognized: spring, summer, autumn and winter. In tropical and subtropical regions, several geographical sectors do not present defined seasons; but in the seasonal tropics, the annual wet and dry seasons are recognized and tracked. A calendar year is an approximation of the number of days of the Earth's orbital period, as counted in a given calendar. The Gregorian calendar, or modern calendar, presents its calendar year to be either a common year of 365 days or a leap year of 366 days, as do the Julian calendars. For the Gregorian calendar, the average length of the calendar year (the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
People From Fincastle, Virginia
A person ( : people) is a being that has certain capacities or attributes such as reason, morality, consciousness or self-consciousness, and being a part of a culturally established form of social relations such as kinship, ownership of property, or legal responsibility. The defining features of personhood and, consequently, what makes a person count as a person, differ widely among cultures and contexts. In addition to the question of personhood, of what makes a being count as a person to begin with, there are further questions about personal identity and self: both about what makes any particular person that particular person instead of another, and about what makes a person at one time the same person as they were or will be at another time despite any intervening changes. The plural form "people" is often used to refer to an entire nation or ethnic group (as in "a people"), and this was the original meaning of the word; it subsequently acquired its use as a plural form of per ...

Biplane
A biplane is a fixed-wing aircraft with two main wings stacked one above the other. The first powered, controlled aeroplane to fly, the Wright Flyer, used a biplane wing arrangement, as did many aircraft in the early years of aviation. While a biplane wing structure has a structural advantage over a monoplane, it produces more drag than a monoplane wing. Improved structural techniques, better materials and higher speeds made the biplane configuration obsolete for most purposes by the late 1930s. Biplanes offer several advantages over conventional cantilever monoplane designs: they permit lighter wing structures, low wing loading and smaller span for a given wing area. However, interference between the airflow over each wing increases drag substantially, and biplanes generally need extensive bracing, which causes additional drag. Biplanes are distinguished from tandem wing arrangements, where the wings are placed forward and aft, instead of above and below. The term is also ...

Aerobatics
Aerobatics is the practice of flying maneuvers involving aircraft attitudes that are not used in conventional passenger-carrying flights. The term is a portmanteau of "aerial" and "acrobatics". Aerobatics are performed in aeroplanes and gliders for training, recreation, entertainment, and sport. Additionally, some helicopters, such as the MBB Bo 105, are capable of limited aerobatic manoeuvres. An example of a fully aerobatic helicopter, capable of performing loops and rolls, is the Westland Lynx. Most aerobatic manoeuvres involve rotation of the aircraft about its longitudinal (roll) axis or lateral (pitch) axis. Other maneuvers, such as a spin, displace the aircraft about its vertical (yaw) axis. Manoeuvres are often combined to form a complete aerobatic sequence for entertainment or competition. Aerobatic flying requires a broader set of piloting skills and exposes the aircraft to greater structural stress than for normal flight. In some countries, the pilot must wear a ...

Monoplane
A monoplane is a fixed-wing aircraft configuration with a single mainplane, in contrast to a biplane or other types of multiplanes, which have multiple planes. A monoplane has inherently the highest efficiency and lowest drag of any wing configuration and is the simplest to build. However, during the early years of flight, these advantages were offset by its greater weight and lower manoeuvrability, making it relatively rare until the 1930s. Since then, the monoplane has been the most common form for a fixed-wing aircraft. Characteristics Support and weight The inherent efficiency of the monoplane is best achieved in the cantilever wing, which carries all structural forces internally. However, to fly at practical speeds the wing must be made thin, which requires a heavy structure to make it strong and stiff enough. External bracing can be used to improve structural efficiency, reducing weight and cost. For a wing of a given size, the weight reduction allows it to fly slower a ...

STOL
A short takeoff and landing (STOL) aircraft is a conventional fixed-wing aircraft that has short runway requirements for takeoff and landing. Many STOL-designed aircraft also feature various arrangements for use on airstrips with harsh conditions (such as high altitude or ice). STOL aircraft, including those used in scheduled passenger airline operations, have also been operated from STOLport airfields which feature short runways. Design considerations Many fixed-wing STOL aircraft are bush planes, though some, like the de Havilland Canada Dash-7, are designed for use on prepared airstrips; likewise, many STOL aircraft are taildraggers, though there are exceptions like the PAC P-750 XSTOL, the Quest Kodiak, the de Havilland Canada DHC-6 Twin Otter and the Peterson 260SE. Autogyros also have STOL capability, needing a short ground roll to get airborne, but capable of a near-zero ground roll when landing. Runway length requirement is a function of the square of the minimum ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Light-sport Aircraft
A light-sport aircraft (LSA), or light sport aircraft, is a fairly new category of small, lightweight aircraft that are simple to fly. LSAs tend to be heavier and more sophisticated than ultralight (aka "microlight") aircraft, but LSA restrictions on weight and performance separates the category from established GA aircraft. There is no standard worldwide description of an LSA . LSAs in different countries The civil aviation authorities in different countries have their own particular specifications and regulations which define the LSA category. For example, in Australia the Civil Aviation Safety Authority defines a light-sport aircraft as a heavier-than-air or lighter-than-air craft, other than a helicopter, with a maximum gross takeoff weight of not more than for lighter-than-air craft; for heavier-than-air craft not intended for operation on water; or for aircraft intended for operation on water. It must have a maximum stall speed of in landing configuration; a maximum ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Aircraft Maintenance Technician
In the US, an aircraft maintenance technician (AMT) is a tradesperson and also refers to a licensed technical qualification for carrying out aircraft maintenance. AMTs inspect and perform or supervise maintenance, preventive maintenance, repairs and alteration of aircraft and aircraft systems. For a person who holds a mechanic certificate issued by the Federal Aviation Administration, the rules for certification, and for certificate-holders, are detailed in Subpart D of Part 65 of the Federal Aviation Regulations (FARs), which are part of Title 14 of the Code of Federal Regulations. The US licensed qualification is sometimes referred to by the FAA as the Aviation Maintenance Technician and is commonly referred to as the Airframe and Powerplant (A&P). Certification The general requirement for eligibility for a mechanic certificate include the following. The candidate must: *Be 18 or older *Be able to read, speak, and understand English fluently; *Meet the experience or educa ...
