WikiProject Aircraft
A WikiProject, or Wikiproject, is an affinity group for contributors with shared goals within the Wikimedia movement. WikiProjects are prevalent within the largest wiki, Wikipedia, and exist to varying degrees within Wikimedia project, sibling projects such as Wiktionary, Wikiquote, Wikidata, and Wikisource. They also exist in different languages, and translation of articles is a form of their collaboration. During the COVID-19 pandemic, CBS News noted the role of Wikipedia's WikiProject Medicine in maintaining the accuracy of articles related to the disease. Another WikiProject that has drawn attention is WikiProject Women Scientists, which was profiled by ''Smithsonian Magazine, Smithsonian'' for its efforts to improve coverage of women scientists which the profile noted had "helped increase the number of female scientists on Wikipedia from around 1,600 to over 5,000".

Rivet
A rivet is a permanent mechanical fastener. Before being installed, a rivet consists of a smooth cylinder (geometry), cylindrical shaft with a head on one end. The end opposite the head is called the ''tail''. On installation, the deformed end is called the ''shop head'' or buck-tail. Because there is effectively a head on each end of an installed rivet, it can support Tension (physics), tension loads. However, it is much more capable of supporting Shear force, shear loads (loads perpendicular to the axis of the shaft). Fastenings used in traditional wooden boat building, such as copper nails and clinch bolts, work on the same principle as the rivet but were in use long before the term ''rivet'' was introduced and, where they are remembered, are usually classified among nails and bolts respectively. History Solid rivets are one of the oldest and most reliable types of fasteners, having been found in archeology, archaeological findings dating back to the Bronze Age. Rivet ...

Ultralight Aircraft (United States)
Ultralight aircraft exist outside of the United States. In most countries, ultralights are a class of aircraft. A completely different legal concept is valid within the USA. The FAA makes explicitly clear that ultralight vehicles are not aircraft, are not regulated as aircraft, and are exempt from aircraft rules. Instead, they are treated as powersport items and have to follow their own ruleset, FAR-103, which is the most compact aviation regulation in existence. It can be printed on the front- and backside of a single piece of paper. (In addition, a few explanatory pages have been published by the FAA.) While ultralights in other countries might have airworthiness certificates, an airworthiness certificate is not allowed for an ultralight vehicle in the USA. (Any existing airworthiness certificate has to be surrendered to the issueing agency, including foreign agencies, before usage as an ultralight vehicle becomes legal.) The FAA emphasizes that airworthiness and complianc ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Light Sport Aircraft
A light-sport aircraft (LSA), or light sport aircraft, is a 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 of two seat ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Canadian Owners And Pilots Association
The Canadian Owners and Pilots Association (COPA) () is a federally registered not-for-profit association that provides information and advocacy services for Canadian pilots who fly for non-commercial purposes. COPA has 13,000 members from every province and territory in Canada. The organization's mission is to "Advance, Promote and Preserve the Canadian Freedom to Fly". Its members represent about 50% of all private and commercial pilots in the country. History COPA was formed in 1952 by Ottawa aviators Margaret Carson and John Bogie. They saw the need for an organization to represent the interests of private pilots to the government of Canada. Their model was based on the US-based Aircraft Owners and Pilots Association (AOPA) which had been formed 13 years earlier in 1939. After meeting with AOPA principals and receiving encouragement from them, COPA was set up with headquarters in Carson's garage. As the association grew, they hired their first paid employees and moved int ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lift Strut
In aeronautics, bracing comprises additional structural members which stiffen the functional airframe to give it rigidity and strength under load. Bracing may be applied both internally and externally, and may take the form of struts, which act in compression or tension as the need arises, and/or wires, which act only in tension. In general, bracing allows a stronger, lighter structure than one which is unbraced, but external bracing in particular adds drag which slows down the aircraft and raises considerably more design issues than internal bracing. Another disadvantage of bracing wires is that they require routine checking and adjustment, or rigging, even when located internally. During the early years of aviation, bracing was a universal feature of all forms of aeroplanes, including the monoplanes and biplanes, which were then equally common. Today, bracing in the form of lift struts is still used for some light commercial designs where a high wing and light weight are more i ...

Transportation Safety Board Of Canada
The Transportation Safety Board of Canada (TSB, ), officially the Canadian Transportation Accident Investigation and Safety Board () is the agency of the Government of Canada responsible for advancing transportation safety in Canada. It is accountable to Parliament directly through the President of the King’s Privy Council and the Minister of Intergovernmental and Northern Affairs and Internal Trade. The independent agency investigates accidents and makes safety recommendations in four modes of transportation: aviation, rail, marine and pipelines. Agency history Prior to 1990, Transport Canada's Aircraft Accident Investigation Branch (1960–1984) and its successor the Canadian Aviation Safety Board or CASB (1984–1990) were responsible for investigation of air incidents. Before 1990, investigations and actions were taken by Transport Canada and even after 1984 the findings from CASB were not binding for Transport Canada to respond to. The TSB was created under the ''Cana ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Gliding
Gliding is a recreational activity and competitive air sports, air sport in which pilots fly glider aircraft, unpowered aircraft known as Glider (sailplane), gliders or sailplanes using naturally occurring currents of rising air in the atmosphere to remain airborne. The word ''soaring'' is also used for the sport. Gliding as a sport began in the 1920s. Initially the objective was to increase the duration of flights but soon pilots attempted cross-country flights away from the place of launch. Improvements in aerodynamics and in the understanding of weather phenomena have allowed greater distances at higher average speeds. Long distances are now flown using any of the main sources of rising air: Ridge Lift, ridge lift, thermals and lee waves. When conditions are favourable, experienced pilots can now fly hundreds of kilometres before returning to their home airfields; occasionally flights of more than are achieved. Some competitive pilots fly in races around pre-defined course ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fuselage
The fuselage (; from the French language, French ''fuselé'' "spindle-shaped") is an aircraft's main body section. It holds Aircrew, crew, passengers, or cargo. In single-engine aircraft, it will usually contain an Aircraft engine, engine as well, although in some amphibious aircraft the single engine is mounted on a hardpoint, pylon attached to the fuselage, which in turn is used as a floating Hull (watercraft), hull. The fuselage also serves to position the Flight control surfaces, control and Stabilizer (aeronautics), stabilization surfaces in specific relationships to Wing, lifting surfaces, which is required for aircraft stability and maneuverability. Types of structures Truss structure This type of structure is still in use in many lightweight aircraft using welding, welded steel tube trusses. A box truss fuselage structure can also be built out of wood—often covered with plywood. Simple box structures may be rounded by the addition of supported lightweight strin ...
