Aeroflot Flight 4225
Aeroflot Flight 4225 was a Tupolev Tu-154B-2 on a scheduled domestic passenger flight from Alma-Ata Airport (now Almaty) to Simferopol Airport on 8 July 1980. The aircraft had reached an altitude of no more than 500 feet when the airspeed suddenly dropped because of thermal currents it encountered during the climb out. This caused the airplane to stall less than from the airport, crash and catch fire, killing all 156 passengers and 10 crew on board. To date, it remains the deadliest aviation accident in Kazakhstan. Accident At the time of the accident, Alma-Ata was experiencing a heat wave. It was around 00:39 and Flight 4225 took off from Alma-Ata Airport in Soviet Kazakhstan. Only a few seconds after take off, the flight reached . The weather was not on the flight's side; the plane reached a zone of hot air and then the Soviet aircraft's airspeed dramatically dropped and the plane was caught in a big downdraft. The Tupolev stalled and plummeted, nose down, into a farm near ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 ...

Aviation Accidents And Incidents In The Soviet Union
Aviation includes the activities surrounding mechanical flight and the aircraft industry. ''Aircraft'' includes fixed-wing and rotary-wing types, morphable wings, wing-less lifting bodies, as well as lighter-than-air craft such as hot air balloons and airships. Aviation began in the 18th century with the development of the hot air balloon, an apparatus capable of atmospheric displacement through buoyancy. Some of the most significant advancements in aviation technology came with the controlled gliding flying of Otto Lilienthal in 1896; then a large step in significance came with the construction of the first powered airplane by the Wright brothers in the early 1900s. Since that time, aviation has been technologically revolutionized by the introduction of the jet which permitted a major form of transport throughout the world. Etymology The word ''aviation'' was coined by the French writer and former naval officer Gabriel La Landelle in 1863. He derived the term from the v ...

Aeroflot Accidents And Incidents
Founded in 1923, Aeroflot, the flag carrier and largest airline of Russia (and formerly the Soviet Union) (formerly the world's largest airline), has had a high number of fatal crashes, with a total of 8,231 passengers dying in Aeroflot crashes according to the Aircraft Crashes Record Office, mostly during the Soviet-era, about five times more than any other airline. From 1946 to 1989, the carrier was involved in 721 incidents. From 1995 to 2017, the carrier was involved in 10 incidents. In 2013, AirlineRatings.com reported that five of the ten aircraft models involved in the highest numbers of fatal accidents were old Soviet models. Following is a list of accidents and incidents Aeroflot experienced from 1932 to the present. 1930s 1940s 1950s 1960s 1970s 1980s 1990s 2000s * On 21 September 2001, Ilyushin Il-86 (RA-86074) landed gear-up at Dubai Airport due to pilot error; all 322 passengers and crew survived, but the aircraft was written off.

Airliner Accidents And Incidents Caused By Microbursts
An airliner is a type of aircraft for transporting passengers and air cargo. Such aircraft are most often operated by airlines. Although the definition of an airliner can vary from country to country, an airliner is typically defined as an airplane intended for carrying multiple passengers or cargo in commercial service. The largest of them are wide-body jets which are also called twin-aisle because they generally have two separate aisles running from the front to the back of the passenger cabin. These are usually used for long-haul flights between airline hubs and major cities. A smaller, more common class of airliners is the narrow-body or single-aisle. These are generally used for short to medium-distance flights with fewer passengers than their wide-body counterparts. Regional airliners typically seat fewer than 100 passengers and may be powered by turbofans or turboprops. These airliners are the non- mainline counterparts to the larger aircraft operated by the major carri ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Accidents And Incidents Involving The Tupolev Tu-154
An accident is an unintended, normally unwanted event that was not directly caused by humans. The term ''accident'' implies that nobody should be blamed, but the event may have been caused by unrecognized or unaddressed risks. Most researchers who study unintentional injury avoid using the term ''accident'' and focus on factors that increase risk of severe injury and that reduce injury incidence and severity. For example, when a tree falls down during a wind storm, its fall may not have been caused by humans, but the tree's type, size, health, location, or improper maintenance may have contributed to the result. Most car wrecks are not true accidents; however English speakers started using that word in the mid-20th century as a result of media manipulation by the US automobile industry. Types Physical and non-physical Physical examples of accidents include unintended motor vehicle collisions, falls, being injured by touching something sharp or hot, or bumping into someth ...

Windshear
Wind shear (or windshear), sometimes referred to as wind gradient, is a difference in wind speed and/or direction over a relatively short distance in the atmosphere. Atmospheric wind shear is normally described as either vertical or horizontal wind shear. Vertical wind shear is a change in wind speed or direction with a change in altitude. Horizontal wind shear is a change in wind speed with a change in lateral position for a given altitude. Wind shear is a microscale meteorological phenomenon occurring over a very small distance, but it can be associated with mesoscale or synoptic scale weather features such as squall lines and cold fronts. It is commonly observed near microbursts and downbursts caused by thunderstorms, fronts, areas of locally higher low-level winds referred to as low-level jets, near mountains, radiation inversions that occur due to clear skies and calm winds, buildings, wind turbines, and sailboats. Wind shear has significant effects on the control of a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
