Utility Aircraft
A utility aircraft is a general-purpose light aircraft, light airplane or helicopter, usually used for transporting people, freight or other supplies, but is also used for other duties when more specialized aircraft are not required or available. The term can also refer to an aircraft type certificated under American, Canadian, European or Australian regulations as a ''Utility Category Aircraft'', which indicates that it is permitted to conduct limited aerobatics. The approved maneuvers include chandelles, Aerobatic maneuver, lazy eights, Spin (aerodynamics), spins and Steep turn (aviation), steep turns over 60° of bank.Crane, Dale: ''Dictionary of Aeronautical Terms, third edition'', page 535. Aviation Supplies & Academics, 1997. In the United States, military utility aircraft are given the prefix U in their United States Department of Defense aerospace vehicle designation, designations. See also * Federal Aviation Regulations#Part 23, FAR Part 23 (refers to "utility category ...

Cirrus SR20
The Cirrus SR20 is an American piston-engined, four- or five-seat composite material, composite monoplane built since 1999 by Cirrus Aircraft of Duluth, Minnesota. The aircraft is the company's earliest type certificate, type-certified model, earning certification in 1998. It was the first production general aviation (GA) aircraft equipped with a Cirrus Airframe Parachute System, parachute to lower the airplane safely to the ground after a loss of control, structural failure, or midair collision. The SR series was also the first mass-manufactured light aircraft with all-composite construction and glass cockpit, flat-panel avionics. The SR20 was developed into the Cirrus SR22, which was introduced in 2001 and is the list of most-produced aircraft, most-produced GA aircraft of the 21st century. Design and development The SR20 mock-up was unveiled in 1994. The aircraft first flew on 21 March 1995 and Federal Aviation Administration, FAA certification was achieved on 23 October 19 ...

Fuel Injected
Fuel injection is the introduction of fuel in an internal combustion engine, most commonly automotive engines, by the means of an injector. This article focuses on fuel injection in reciprocating piston and Wankel rotary engines. All compression-ignition engines (e.g. diesel engines), and many spark-ignition engines (i.e. petrol engines, such as Otto or Wankel), use fuel injection of one kind or another. Mass-produced diesel engines for passenger cars (such as the Mercedes-Benz OM 138) became available in the late 1930s and early 1940s, being the first fuel-injected engines for passenger car use. In passenger car petrol engines, fuel injection was introduced in the early 1950s and gradually gained prevalence until it had largely replaced carburettors by the early 1990s. The primary difference between carburetion and fuel injection is that fuel injection atomizes the fuel through a small nozzle under high pressure, while a carburettor relies on suction created by intake air ...

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 ...

Wheel Pants
An aircraft fairing is a structure whose primary function is to produce a smooth outline and reduce drag.Crane, Dale: ''Dictionary of Aeronautical Terms, Third Edition'', page 206. Aviation Supplies & Academics Inc, Newcastle Washington, 1997. These structures are covers for gaps and spaces between parts of an aircraft to reduce form drag and interference drag, and to improve appearance.Bingelis, Tony: ''The Sportplane Builder'', pages 261-265. Experimental Aircraft Association Aviation Foundation, 1979. Types On aircraft, fairings are commonly found on: ; Belly fairing : Also called a "ventral fairing", it is located on the underside of the fuselage between the main wings. It can also cover additional cargo storage or fuel tanks. ; Cockpit fairing : Also called a "cockpit pod", it protects the crew on ultralight trikes. Commonly made from fiberglass, it may also incorporate a windshield.Cliche, Andre: ''Ultralight Aircraft Shopper's Guide'' 8th Edition, page C-17. Cybair ...

Wing Tip
A wing tip (or wingtip) is the part of the wing that is most distant from the fuselage of a fixed-wing aircraft. Because the wing tip shape influences the size and drag of the wingtip vortices, tip design has produced a diversity of shapes, including: * Squared-off * Aluminium tube bow * Rounded * Hoerner style * Winglets * Drooped tips * Raked wingtips * Tip tanks * Sails * Fences * End plates Winglets have become popular additions to high speed aircraft to increase fuel efficiency by reducing drag from wingtip vortices. In lower speed aircraft, the effect of the wingtip shape is less apparent, with only a marginal performance difference between round, square, and Hoerner style tips The slowest speed aircraft, STOL aircraft, may use wingtips to shape airflow for controllability at low airspeeds. Wing tips are also an expression of aircraft design style, so their shape may be influenced by marketing considerations as well as by aerodynamic requirements. Wing tips are ...

Avgas
Avgas (aviation gasoline, also known as aviation spirit in the UK) is an aviation fuel used in aircraft with spark-ignited internal combustion engines. ''Avgas'' is distinguished from conventional gasoline (petrol) used in motor vehicles, which is termed ''mogas'' (motor gasoline) in an aviation context. Unlike motor gasoline, which has been formulated since the 1970s to allow the use of platinum-content catalytic converters for pollution reduction, the most commonly used grades of avgas still contain tetraethyllead (TEL), a toxic substance used to prevent engine knocking (premature detonation). There are ongoing experiments aimed at eventually reducing or eliminating the use of TEL in aviation gasoline. Kerosene-based jet fuel is formulated to suit the requirements of turbine engines which have no octane requirement and operate over a much wider flight envelope than piston engines. Kerosene is also used by most diesel piston engines developed for aviation use, such as tho ...

Constant-speed Propeller
In aeronautics, a variable-pitch propeller is a type of propeller (airscrew) with blades that can be rotated around their long axis to change the blade pitch. A controllable-pitch propeller is one where the pitch is controlled manually by the pilot. Alternatively, a constant-speed propeller is one where the pilot sets the desired engine speed ( RPM), and the blade pitch is controlled automatically without the pilot's intervention so that the rotational speed remains constant. The device which controls the propeller pitch and thus speed is called a propeller governor or constant speed unit. Reversible propellers are those where the pitch can be set to negative values. This creates reverse thrust for braking or going backwards without the need to change the direction of shaft revolution. Some aircraft have ground-adjustable propellers, however these are not considered variable-pitch. These are typically found only on light aircraft and microlights. Purpose When an aircraft is ...

Continental O-300
The Continental O-300 and the C145 are a family of air-cooled flat-6 aircraft piston engines built by Teledyne Continental Motors.Christy, Joe: ''Engines for Homebuilt Aircraft & Ultralights'', pages 60-63. TAB Books, 1983. First produced in 1947, versions were still in production . It was produced under licence in the United Kingdom by Rolls-Royce in the 1960s. Development The C-145 was developed from the C-125 engine. Both powerplants share the same crankcase, although the C-145 produces an additional through a longer piston stroke, higher compression ratio of 7.0:1 and different carburetor jetting. The O-300 is a modernized C-145 and retains the same weight, dimensions, bore, stroke, compression ratio, displacement and output power of the earlier engine. GO-300 The GO-300 employs a reduction gearbox, so that the engine turns at 3200 rpm to produce a propeller rpm of 2400. The GO-300 produces whereas the ungeared O-300 produces . The GO-300 engine has a TBO (Time ...
