Frankfort Dow Memorial Field
Frankfort Dow Memorial Field is a public use airport located two nautical miles (3.7 km) southeast of the central business district of Frankfort, a city in Benzie County, Michigan, United States. It is owned by the Frankfort City-County Airport Authority. It is included in the Federal Aviation Administration (FAA) National Plan of Integrated Airport Systems for 2017–2021, in which it is categorized as a general aviation facility. Although many U.S. airports use the same three-letter location identifier for the FAA and IATA, this airport is assigned FKS by the FAA and no designation from the IATA (which assigned FKS to Fukushima Airport in Fukushima Prefecture, Japan). History In 1937, Frankfort was identified as one of the United States' premier spots for glider flying. National soaring meets were held in the area. A flight school was established in Frankfort in the 1940s. In 2015, the airport's license was downgraded to a basic utility license when it was found there ...

Runway
According to the International Civil Aviation Organization (ICAO), a runway is a "defined rectangular area on a land aerodrome prepared for the landing and takeoff of aircraft". Runways may be a man-made surface (often asphalt concrete, asphalt, concrete, or a mixture of both) or a natural surface (sod, grass, soil, dirt, gravel, ice, sand or road salt, salt). Runways, as well as taxiways and Airport apron, ramps, are sometimes referred to as "tarmac", though very few runways are built using Tarmacadam, tarmac. Takeoff and landing areas defined on the surface of water for seaplanes are generally referred to as waterways. Runway lengths are now International Civil Aviation Organization#Use of the International System of Units, commonly given in meters worldwide, except in North America where feet are commonly used. History In 1916, in a World War I war effort context, the first concrete-paved runway was built in Clermont-Ferrand in France, allowing local company Michelin to ...

Great Lakes Sport Trainer
The Great Lakes Sport Trainer is an American biplane trainer and aerobatic aircraft. It was originally produced in large numbers before the company building it went bankrupt in the Great Depression in 1933. Owing to its continuing popularity, however, it was eventually placed back into production in the 1970s and again in 2011 by WACO Classic Aircraft. Development and design The Great Lakes Aircraft Corporation of Cleveland, Ohio produced a design for a small two-seat sports/trainer in early 1929, with the first prototype flying in March 1929.Donald 1997, p.467. The resulting aircraft, designated 2-T-1 was a single bay biplane of mixed, fabric-covered construction and with a tailskid undercarriage. Power was by a single Cirrus III inline engine (as the Detroit Aircraft Corporation, the holding company for Great Lakes, also held the American rights to the Cirrus, so all Sports Trainers were originally sold with Cirrus engines).

Stall (fluid Dynamics)
In fluid dynamics, a stall is a reduction in the lift coefficient generated by a foil as angle of attack increases.Crane, Dale: ''Dictionary of Aeronautical Terms, third edition'', p. 486. Aviation Supplies & Academics, 1997. This occurs when the critical angle of attack of the foil is exceeded. The critical angle of attack is typically about 15°, but it may vary significantly depending on the fluid, foil, and Reynolds number. Stalls in fixed-wing flight are often experienced as a sudden reduction in lift as the pilot increases the wing's angle of attack and exceeds its critical angle of attack (which may be due to slowing down below stall speed in level flight). A stall does not mean that the engine(s) have stopped working, or that the aircraft has stopped moving—the effect is the same even in an unpowered glider aircraft. Vectored thrust in aircraft is used to maintain altitude or controlled flight with wings stalled by replacing lost wing lift with engine or propeller thr ...

Cessna Skymaster
The Cessna Skymaster is an American twin-engine civil utility aircraft built in a push-pull configuration. Its engines are mounted in the nose and rear of its pod-style fuselage. Twin booms extend aft of the wings to the vertical stabilizers, with the rear engine between them. The horizontal stabilizer is aft of the pusher propeller, mounted between and connecting the two booms.Wood, Derek: ''Jane's World Aircraft Recognition Handbook'', page 471. Jane's Publishing Company, 1985. The combined tractor and pusher engines produce centerline thrust and a unique sound.Plane and Pilot: ''1978 Aircraft Directory'', page 92. Werner & Werner Corp Publishing, 1978. The Cessna O-2 Skymaster is a military version of the Cessna 337 Super Skymaster. Development The first Skymaster, Model 336 Skymaster, had fixed landing gear and initially flew on February 28, 1961.Taylor, Michael: ''Encyclopedia of Modern Military Aircraft''; page 67; Gallery Books; 1987; It went into production in Ma ...

Marsh
A marsh is a wetland that is dominated by herbaceous rather than woody plant species.Keddy, P.A. 2010. Wetland Ecology: Principles and Conservation (2nd edition). Cambridge University Press, Cambridge, UK. 497 p Marshes can often be found at the edges of lakes and streams, where they form a transition between the aquatic and terrestrial ecosystems. They are often dominated by grasses, rushes or reeds. If woody plants are present they tend to be low-growing shrubs, and the marsh is sometimes called a carr. This form of vegetation is what differentiates marshes from other types of wetland such as swamps, which are dominated by trees, and mires, which are wetlands that have accumulated deposits of acidic peat. Marshes provide habitats for many kinds of invertebrates, fish, amphibians, waterfowl and aquatic mammals. This biological productivity means that marshes contain 0.1% of global sequestered terrestrial carbon. Moreover, they have an outsized influence on climate resi ...

Glider Towing
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] |
Cessna O-1 Bird Dog
The Cessna L-19/O-1 Bird Dog is a liaison and observation aircraft. It was the first all-metal fixed-wing aircraft ordered for and by the United States Army following the Army Air Forces' separation from it in 1947. The Bird Dog had a lengthy career in the U.S. military, as well as in other countries. Design and development The U.S. Army was searching for an aircraft that could adjust artillery fire, as well as perform liaison duties, and preferably be constructed of all metal, as the fabric-covered liaison aircraft used during World War II (primarily Stinson and Piper products) had short service lives. After the specification for a two-seat liaison and observation monoplane was issued the Cessna Aircraft Company submitted the Cessna Model 305A, a development of the Cessna 170. The Cessna 305A was a single-engine, lightweight, strut-braced, high-wing monoplane with a tailwheel landing gear. The greatest difference from the Cessna 170 was that the 305A had only two seats, in ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
M-115 (Michigan Highway)
M-115 is a state trunkline highway in the northwestern part of the Lower Peninsula of the US state of Michigan. The highway takes a generally southeast-to-northwest direction between Frankfort on Lake Michigan and Clare in the central part of the state. The northwestern end is at M-22 next to Betsie Lake; the southeastern end in downtown Clare is at an intersection with Business US Highway 127 (Bus. US 127) and Bus. US 10. In between, the trunkline runs about through woodlands, including areas that are a part of either the Manistee National Forest or the Pere Marquette State Forest. The highway also passes agricultural areas, several lakes in the region and a state park near Cadillac. M-115 was first designated in the 1920s on the northwestern end near Frankfort. Additional, disconnected sections were designed as part of the trunkline in the 1930s near Cadillac, Farwell and Mesick. All but one of these gaps (Cadillac–Mesick) was eliminated by the end of tha ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
M-22 (Michigan Highway)
M-22 is a state trunkline highway in the US state of Michigan. It is long and follows the Lake Michigan shoreline of the Leelanau Peninsula, making up a portion of the Lake Michigan Circle Tour. It also passes through the Sleeping Bear Dunes National Lakeshore. The highway is U-shaped as it rounds the peninsula running through tourist areas in Leland and Suttons Bay in addition to the national lakeshore. M-22 is an original trunkline designation dating back to the 1919 designation of the system. Reroutings have moved the highway closer to the water between Suttons Bay and Traverse City. A section of the highway was used temporarily for another highway, M-109. Two sections of the highway have been designated as separate Pure Michigan Byways. The highway marker is used in marketing by a local business as a symbol of the region, a trademark for which has been the subject of legal controversies. A popular roadway in the area with tourists, the highway's marker has also been the s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Glider (aircraft)
A glider is a fixed-wing aircraft that is supported in flight by the dynamic reaction of the air against its lifting surfaces, and whose free flight does not depend on an engine. Most gliders do not have an engine, although motor-gliders have small engines for extending their flight when necessary by sustaining the altitude (normally a sailplane relies on rising air to maintain altitude) with some being powerful enough to take off by self-launch. There are a wide variety of types differing in the construction of their wings, aerodynamic efficiency, location of the pilot, controls and intended purpose. Most exploit meteorological phenomena to maintain or gain height. Gliders are principally used for the air sports of gliding, hang gliding and paragliding. However some spacecraft have been designed to descend as gliders and in the past military gliders have been used in warfare. Some simple and familiar types of glider are toys such as paper planes and balsa wood gliders. Etym ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Helicopter
A helicopter is a type of rotorcraft in which lift and thrust are supplied by horizontally spinning rotors. This allows the helicopter to take off and land vertically, to hover, and to fly forward, backward and laterally. These attributes allow helicopters to be used in congested or isolated areas where fixed-wing aircraft and many forms of STOL (Short TakeOff and Landing) or STOVL (Short TakeOff and Vertical Landing) aircraft cannot perform without a runway. In 1942, the Sikorsky R-4 became the first helicopter to reach full-scale production.Munson 1968.Hirschberg, Michael J. and David K. Dailey"Sikorsky". ''US and Russian Helicopter Development in the 20th Century'', American Helicopter Society, International. 7 July 2000. Although most earlier designs used more than one main rotor, the configuration of a single main rotor accompanied by a vertical anti-torque tail rotor (i.e. unicopter, not to be confused with the single-blade monocopter) has become the most comm ...
