Capital Airlines Flight 67
Capital Airlines Flight 67 was a domestic scheduled U.S. passenger flight operated by Capital Airlines which crashed on final approach to Freeland, Michigan, during a severe snowstorm on April 6, 1958, killing all 47 people on board. The flight was en route from Flint-Bishop Airport to the Freeland-Tri City Airport (now MBS International Airport) when it crashed. �PDF/ref> Flight 67 was the first of four fatal crashes in the space of two years involving Capital Airlines Vickers Viscounts; the others were Flight 300 (May 1958), Flight 75 (May 1959), and Flight 20 (January 1960). Accident Approach conditions towards Freeland were poor due to the weather; there was restricted visibility, and conditions were ripe for icing. The plane's crew apparently attempted a steep turn to align the craft with the runway. This caused the plane to stall, which was followed by a spin. The crew could not regain control, leading to the crash. Investigation The official cause of the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Aerodynamic Stall
In fluid dynamics, a stall is a reduction in the lift coefficient generated by a foil as angle of attack exceeds its critical value.Crane, Dale: ''Dictionary of Aeronautical Terms, third edition'', p. 486. Aviation Supplies & Academics, 1997. The critical angle of attack is typically about 15°, but it may vary significantly depending on the fluid, foil – including its shape, size, and finish – and Reynolds number. Stalls in fixed-wing aircraft are often experienced as a sudden reduction in lift. It may be caused either by the pilot increasing the wing's angle of attack or by a decrease in the critical angle of attack. The former may be due to slowing down (below stall speed), the latter by accretion of ice on the wings (especially if the ice is rough). 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 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Midway International Airport
Chicago Midway International Airport is a major commercial airport on the southwest side of Chicago, Illinois, located approximately 12 miles (19 km) from the city's Loop business district, and divided between the city's Clearing and Garfield Ridge communities. Established in 1927, Midway served as Chicago's primary airport until the opening of O'Hare International Airport in 1944. Midway is one of the busiest airports in the nation and the second-busiest airport in both the Chicago metropolitan area and the state of Illinois, serving 22,050,489 passengers in 2023. Midway is a base for Southwest Airlines, which carries over 90% of the passengers at the airport. The airport was named in honor of the Battle of Midway. The defunct Midway Airlines, once headquartered at Midway, took its name from the airport. The airfield is located in a square mile bounded by 55th and 63rd Streets, Central and Cicero Avenues. The terminal complex was completed in 2001. The terminal ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Midland Daily News
The ''Midland Daily News'' is a daily newspaper which serves Midland County, Michigan. The offices for the paper are located at 219 East Main Street in downtown Midland; the paper is widely circulated around Midland County. The newspaper also prints the school newspaper for Herbert Henry Dow High School, ''The Update''. The ''Daily News'' is the last daily newspaper in the Tri-Cities left with a regular print schedule, since the ''Bay City Times'' and ''Saginaw News'' cut back their print editions to three times a week in June 2009. It publishes 6 days a week, with a weekend edition. History The paper can trace its lineage to the 1858 founding of the ''Midland Sentinel'', which after a number of ownership and name changes became the ''Midland Republican'' in 1881. In 1937, ''Republican'' publisher Philip T. Rich founded the ''Midland Daily News'' as a successor to the weekly ''Republican''. In 1968, Rich sold the paper to Lindsay-Schaub Newspapers, a company based in Decatur ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Horizontal Stabilizer
A tailplane, also known as a horizontal stabilizer, is a small lifting surface located on the tail ( empennage) behind the main lifting surfaces of a fixed-wing aircraft as well as other non-fixed-wing aircraft such as helicopters and gyroplanes. Not all fixed-wing aircraft have tailplanes. Canards, tailless and flying wing aircraft have no separate tailplane, while in V-tail aircraft the vertical stabilizer, rudder, and the tail-plane and elevator are combined to form two diagonal surfaces in a V layout. The function of the tailplane is to provide stability and control. In particular, the tailplane helps adjust for changes in position of the centre of pressure or centre of gravity caused by changes in speed and attitude, fuel consumption, or dropping cargo or payload. Tailplane types The tailplane comprises the tail-mounted fixed horizontal stabilizer and movable elevator. Besides its planform, it is characterised by: *Number of tailplanes - from 0 ( tailless or canard) ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Spin (aerodynamics)
In flight dynamics (fixed-wing aircraft), flight dynamics a spin is a special category of Stall (fluid dynamics), stall resulting in Autorotation (fixed-wing aircraft), autorotation (uncommanded roll) about the aircraft's longitudinal axis and a shallow, rotating, downward path approximately centred on a vertical axis. Spins can be entered intentionally or unintentionally, from any flight attitude if the aircraft has sufficient Yaw axis, yaw while at the stall point. In a normal spin, the wing on the inside of the turn stalls while the outside wing remains flying. It is possible for both wings to stall, but the angle of attack of each wing, and consequently its Lift (force), lift and Drag (physics), drag, are different. Either situation causes the aircraft to autorotate toward the stalled wing due to its higher drag and loss of lift. Spins are characterized by high angle of attack, an airspeed below the stall on at least one wing and a shallow descent. Recovery and avoiding a cr ...

Runway
In aviation, a runway is an elongated, rectangular surface designed for the landing and takeoff of an aircraft. Runways may be a human-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, 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 manufacture Bréguet Aviation military aircraft. In January 1919, aviation p ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Atmospheric Icing
Atmospheric icing occurs in the atmosphere when water droplets suspended in air freeze on objects they come in contact with. It is not the same as freezing rain, which is caused directly by precipitation. Atmospheric icing occurs on aircraft, towers, wind turbines, boats, oil rigs, and trees. Unmanned aircraft are particularly sensitive to icing. In cold climates, particularly those at higher elevations, atmospheric icing is common in winter as elevated terrain interacts with supercooled clouds that can cause icing on contact. Ice loads are a major cause of catastrophic failures of overhead electrical power lines, as power lines can break under the weight of accumulated ice. Therefore, estimation of maximum potential ice load is crucial in the structural design of power line systems to withstand ice loads, and this can be done with numerical icing models and examples that include meteorological data. Formation Water does not always freeze at . Water that persists in liqui ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Capital Airlines Flight 20
Capital Airlines Flight 20 was a United States, U.S. scheduled passenger flight from Washington, D.C. to Norfolk, Virginia. A Vickers Viscount flying the route crashed into a farm in Charles City County, Virginia, on January 18, 1960. The accident was the fourth fatal crash involving a Capital Viscount in less than two years; the first three were Capital Airlines Flight 67 (April 1958), Capital Airlines Flight 300 (May 1958) and Capital Airlines Flight 75 (May 1959). The plane was cruising at an altitude of 8,000 feet when it encountered atmospheric icing, icing. This caused two aircraft engine, engines to fail. As the craft descended, the other two engines also failed, causing the propellers to autofeather. The crew tried and failed to restart the engines, and were unable to unfeather the propellers normally; they then put the plane into a dive in an attempt to force the propellers from their feathered position. Eventually they succeeded in restarting engine number four. They a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Capital Airlines Flight 75
Capital Airlines Flight 75 was a domestic scheduled Capital Airlines passenger flight between LaGuardia Airport and Hartsfield–Jackson Atlanta International Airport in Atlanta, Georgia. A Vickers Viscount flying the route crashed near Chase, Maryland, on May 12, 1959, with the loss of all on board. The crash was the third of four involving a Capital Airlines Vickers Viscount in less than two years; the other three were Capital Airlines Flight 67 (April 1958), Capital Airlines Flight 300 (May 1958), and Capital Airlines Flight 20 (January 1960). Accident The flight left the terminal at La Guardia at 3:20 in the afternoon, 20 minutes behind schedule, and took off at 3:29. It then climbed to 14,000 feet before coming onto the assigned airway, Victor 3. At 4:02, the crew contacted Washington Center, reporting over Westchester, and estimating Westminster to be 15 minutes away. In the same message, they noted that thunderstorms existed along the assigned course, and reque ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Capital Airlines Flight 300
On May 20, 1958 a Vickers Viscount airliner operating Capital Airlines Flight 300 was involved in a mid-air collision with a United States Air Force T-33 jet trainer on a proficiency flight in the skies above Brunswick, Maryland. All 11 people on board the Viscount and one of the two crew in the T-33 were killed in the accident. Flight 300 was the second of four fatal crashes in under two years involving Capital Airlines Viscounts; the others were Flight 67 (April 1958), Flight 75 (May 1959), and Flight 20 (January 1960). An investigation of the accident concluded that the pilot in command of the T-33 failed to see and maintain a safe distance from other air traffic. Accident Capital Airlines Flight 300 was a regular scheduled flight from Chicago, Illinois to Baltimore, Maryland with an intermediate stop at Pittsburgh, Pennsylvania. The flight from Chicago was uneventful and at 10:50 local time the airliner departed Pittsburgh bound for Baltimore. At 11:25 while cruising at ...

Snowstorm
A winter storm (also known as snow storm) is an event in which wind coincides with varieties of precipitation that only occur at freezing temperatures, such as snow, Rain and snow mixed, mixed snow and rain, or freezing rain. In Continental climate, temperate continental and subarctic climates, these storms are not necessarily restricted to the winter season, but may occur in the late autumn and early spring as well. A snowstorm with strong winds and low visibility is called a blizzard. Formation Winter storms are formed when moist air rises up into the atmosphere, creating Low-pressure area, low pressure near the ground and clouds up in the air. The air can also be pushed upwards by hills or large mountains. The upward motion is called Lift (force), lift. The moisture is collected by the wind from large bodies of water, such as a big lake or the ocean. If temperature is below freezing, , near the ground and up in the clouds, precipitation will fall as snow, ice, rain and s ...

Final Approach (aeronautics)
In aeronautics, the final approach (also called the final leg and final approach leg) is the last leg in an aircraft's approach to landing, when the aircraft is lined up with the runway and descending for landing.Crane, Dale: ''Dictionary of Aeronautical Terms, third edition'', page 213 and 241. Aviation Supplies & Academics, 1997. In aviation radio terminology, it is often shortened to "final". The last section of the final approach is sometimes referred to as short final. In a standard airport landing pattern, which is usually used under visual meteorological conditions (VMC), aircraft turns from base leg to final within one-half to two miles of the airport. For instrument approaches, as well as approaches into a controlled airfield under visual flight rules (VFR), often a "straight-in" final approach is used, where all the other legs are dispensed within. Straight-in approaches are discouraged at non-towered airports in the United States. Approach slope An approach slo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
