Flight With Disabled Controls
Throughout a normal flight, a pilot controls an aircraft through the use of flight controls including maintaining straight and level flight, as well as turns, climbing, and descending. Some controls, such as a "yoke" or "stick" move and adjust the control surfaces which affects the aircraft's attitude in the three axes of pitch, roll, and yaw. Other controls include those for adjusting wing characteristics (flaps, slats, spoilers) and those that control the power or thrust of the propulsion systems. The loss of primary control systems in any phase of flight is an emergency. Aircraft are not designed to be flown under such circumstances; however, some pilots faced with such an emergency have had limited success flying and landing aircraft with disabled controls. Control system failures resulting in disabled controls have resulted in a number of aviation incidents and accidents. Some incidents occurred where controls were not functioning correctly prior to take-off, others wher ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Flight Control Surfaces
Flight control surfaces are aerodynamic devices allowing a pilot to adjust and control the aircraft's flight attitude. The primary function of these is to control the aircraft's movement along the three axes of rotation. Flight control surfaces are generally operated by dedicated aircraft flight control systems. Development of an effective set of flight control surfaces was a critical advance in the history of development of aircraft. Early efforts at fixed-wing aircraft design succeeded in generating sufficient lift to get the aircraft off the ground, however with limited control. The development of effective flight controls allowed stable flight. A conventional fixed-wing aircraft uses three primary flight control surfaces– aileron, rudder and elevator to control the roll, yaw, and pitch respectively. Secondary flight control surfaces might include spoiler, flaps, and slats on the wings. The main control surfaces of a fixed-wing aircraft are attached to the airfram ...

Eastern Air Lines Flight 935
Eastern Air Lines Flight 935 was a scheduled commercial passenger flight operated by Eastern Air Lines. On September 22, 1981, the Lockheed L-1011 TriStar jet operating the flight suffered an uncontained engine failure which led to a loss of 3 out of the 4 hydraulic systems aboard the aircraft at an altitude of MSL. The crew were able to land the aircraft safely to an emergency landing at John F. Kennedy International Airport with some limited use of the outboard spoilers, the inboard ailerons and the horizontal stabilizer, plus differential engine power of the remaining two engines. There were no injuries. Aircraft The plane was a Lockheed L-1011 Tristar, registration C/n / msn: 1010, fitted with Rolls-Royce RB211-22B turbofan engines, delivered in July 1972. In April 1973 and 1974, the plane was leased to Trans World Airlines under the same registration.

Dennis E
Dennis or Denis is a first or last name from the Greco-Roman name Dionysius, via one of the Christian saints named Dionysius. The name came from Dionysus, the Greek god of ecstatic states, particularly those produced by wine, which is sometimes said to be derived from the Greek Dios (Διός, "of Zeus") and Nysos or Nysa (Νῦσα), where the young god was raised. Dionysus (or Dionysos; also known as Bacchus in Roman mythology and associated with the Italic Liber), the Thracian god of wine, represents not only the intoxicating power of wine, but also its social and beneficent influences. He is viewed as the promoter of civilization, a lawgiver, and a lover of peace—as well as the patron deity of both agriculture and the theatre. Dionysus is a god of mystery religious rites, such as those practised in honour of Demeter and Persephone at Eleusis near Athens. In the Thracian mysteries, he wears the "bassaris" or fox-skin, symbolizing new life. (See also Maenads.) A mediae ...

McDonnell Douglas DC-10
The McDonnell Douglas DC-10 is an American trijet wide-body aircraft manufactured by McDonnell Douglas. The DC-10 was intended to succeed the Douglas DC-8, DC-8 for long-Range (aeronautics), range flights. It first flew on August 29, 1970; it was introduced on August 5, 1971, by American Airlines. The trijet has two turbofans on underwing pylons and a third one at the base of the vertical stabilizer. The twin-aisle layout has a typical seating for 270 in two classes. The initial DC-10-10 had a range for transcontinental flights. The DC-10-15 had more powerful engines for hot and high airports. The DC-10-30 and –40 models (with a third main landing gear leg to support higher weights) each had intercontinental ranges of up to . The KC-10 Extender (based on the DC-10-30) is a tanker aircraft that was primarily operated by the United States Air Force. Early operations of the DC-10 were afflicted by its poor safety record, which was partially attributable to a design flaw i ...

United Airlines Flight 232
United Airlines Flight 232 was a regularly scheduled United Airlines flight from Stapleton International Airport in Denver to O'Hare International Airport in Chicago, continuing to Philadelphia International Airport. On July 19, 1989, the DC-10 (registered as N1819U) serving the flight crash-landed at Sioux Gateway Airport in Sioux City, Iowa, after suffering a catastrophic failure of its tail-mounted engine due to an unnoticed manufacturing defect in the engine's fan disk, which resulted in the loss of all flight controls. Of the 296 passengers and crew on board, 112 died during the accident, while 184 people survived. Thirteen of the passengers were uninjured. It was the deadliest single-aircraft accident in the history of United Airlines. Despite the fatalities, the accident is considered a good example of successful crew resource management, a new concept at the time. Contributing to the outcome was the crew's decision to recruit the assistance of a company check pilot, ...

Trim Tab
Trim tabs are small surfaces connected to the trailing edge of a larger Flight control surfaces, control surface on a boat or aircraft, used to control the trim of the controls, i.e. to counteract hydro- or aerodynamic forces and stabilise the boat or aircraft in a particular desired Orientation (geometry), attitude without the need for the operator to constantly apply a control force. This is done by adjusting the angle of the tab relative to the larger surface. Changing the setting of a trim tab adjusts the neutral or resting position of a control surface (such as an Elevator (aircraft), elevator or rudder). As the desired position of a control surface changes (corresponding mainly to different speeds), an adjustable trim tab will allow the operator to reduce the manual force required to maintain that position—to zero, if desired. Thus the trim tab acts as a servo tab. Because the Center of pressure (fluid mechanics), center of pressure of the trim tab is farther away from t ...

Rapid Decompression
An uncontrolled decompression is an undesired drop in the pressure of a sealed system, such as a pressurised aircraft cabin or hyperbaric chamber, that typically results from human error, structural failure, or impact, causing the pressurised vessel to vent into its surroundings or fail to pressurize at all. Such decompression may be classed as ''explosive, rapid'', or ''slow'': * Explosive decompression (ED) is violent and too fast for air to escape safely from the lungs and other air-filled cavities in the body such as the sinuses and eustachian tubes, typically resulting in severe to fatal barotrauma. * Rapid decompression may be slow enough to allow cavities to vent but may still cause serious barotrauma or discomfort. * Slow or gradual decompression occurs so slowly that it may not be sensed before hypoxia sets in. Description The term ''uncontrolled decompression'' here refers to the unplanned depressurisation of vessels that are occupied by people; for example, a pressu ...

Ilyushin Il-62
The Ilyushin Il-62 (; NATO reporting name: Classic) is a Soviet Union, Soviet long-range Narrow-body aircraft, narrow-body jetliner conceived in 1960 by Ilyushin. As a successor to the popular turboprop Ilyushin Il-18, Il-18 and with capacity for almost 200 passengers and crew, the Il-62 was the world's largest jet airliner when first flown in 1963. The seventh quad-engined, long-range jet airliner to fly (the predecessors being the De Havilland Comet (1949), Avro Jetliner (1949), Boeing 707 (1954), Douglas DC-8 (1958), Vickers VC10 (1962), and experimental Tupolev Tu-110 (1957)), it was the first such type to be operated by the Soviet Union and a number of allied nations. The Il-62 entered Aeroflot civilian service on 15 September 1967 with an inaugural passenger flight from Moscow to Montreal and remained the standard long-range airliner for the Soviet Union (and later, Russia) for several decades. It was the first Soviet pressurised aircraft with non-circular cross-section ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

LOT Polish Airlines Flight 5055
LOT Polish Airlines Flight 5055 was a scheduled international passenger flight from Warsaw to New York City. In the late-morning hours of 9 May 1987, the Ilyushin Il-62M operating the flight crashed in the Kabaty Woods nature reserve on the outskirts of Warsaw around 56 minutes after departure. All 183 passengers and crew on board were killed in the crash, making it the deadliest accident involving an Ilyushin Il-62, and the deadliest aviation disaster in Polish history. The accident was determined to have been caused by the disintegration of an engine shaft due to faulty bearings. This led to a catastrophic failure of the two left engines and then an onboard fire, both of which eventually destroyed all flight-control systems. Aircraft The aircraft was a 186-seat Ilyushin Il-62M built in the third quarter of 1983, registered SP-LBG and named after Tadeusz Kościuszko, a Polish military leader and national hero. The Il-62 has four tail-mounted engines, with two on the lef ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Cold Bay, Alaska
Cold Bay (,; Sugpiaq: ''Pualu'') is a city in Aleutians East Borough, Alaska, United States. As of the 2010 census, the population was 108, but at the 2020 census this had reduced to 50. Cold Bay is one of the main commercial centers of the Alaska Peninsula, which extends west towards the Aleutian Islands, and is home to Cold Bay Airport. History There is evidence of prehistoric occupation by Aleuts and later Russian encampments. Cold Bay's significance to American history began with the Japanese invasion of the Aleutians in World War II. General Simon Bolivar Buckner, Jr. ordered the creation of Fort Randall, an airbase on the shores of Cold Bay, in 1942 as a part of a general expansion of American assets in the Aleutians. It (along with Otter Point) served as a base for the 11th Air Force to provide protection to the only deep water port in the Aleutians at the time, Dutch Harbor. This protection was necessary when during Yamamoto's Midway Campaign, a diversionary ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Lockheed L-188 Electra
The Lockheed L-188 Electra is an American turboprop airliner built by Lockheed Corporation, Lockheed. First flown in 1957, it was the first large turboprop airliner built in the United States. With its fairly high power-to-weight ratio, huge propellers and very short wings (resulting in the majority of the wingspan being enveloped in propwash), large Fowler flaps which significantly increased effective wing area when extended, and four-engined design, the airplane had airfield performance capabilities unmatched by many jet transport aircraft even today—particularly on short runways and high altitude airfields. Initial sales were good, but after two fatal crashes that led to expensive modifications to fix a design defect, no more were ordered. Jet airliners soon supplanted turboprops for many purposes, and many Electras were modified as freighters. Some Electras are still being used in various roles into the 21st century. The airframe was also used as the basis for the Lockheed P ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |
