Pulkovo Airlines Flight 612
Pulkovo Aviation Enterprise Flight 612 was a scheduled passenger flight operated by Saint Petersburg-based airline Pulkovo Aviation Enterprise, flying from Anapa Airport to Pulkovo Airport in Saint Petersburg. The aircraft crashed in Donetsk Oblast in eastern Ukraine, near the Russian border, on 22 August 2006. All 170 people on board were killed. The crash was the deadliest aviation accident in 2006. At the time it was the deadliest crash in modern Ukrainian history and the second deadliest in Ukraine SSR, after the 1979 Dniprodzerzhynsk mid-air collision. The death toll was eventually surpassed in 2014 when Malaysia Airlines Flight 17 was shot down east of where Flight 612 had crashed, also located in Donetsk Oblast, killing all 298 people on board. Aircraft Pulkovo Aviation Enterprise Flight 612 was served by a Russian Tupolev Tu-154M airliner (registration: RA-85185). The aircraft did not refuel in Anapa and departed on time.

Stall (fluid Mechanics)
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 thru ...

Angle Of Attack
In fluid dynamics, angle of attack (AOA, α, or \alpha) is the angle between a reference line on a body (often the chord line of an airfoil) and the vector representing the relative motion between the body and the fluid through which it is moving. Angle of attack is the angle between the body's reference line and the oncoming flow. This article focuses on the most common application, the angle of attack of a wing or airfoil moving through air. In aerodynamics, angle of attack specifies the angle between the chord line of the wing of a fixed-wing aircraft and the vector representing the relative motion between the aircraft and the atmosphere. Since a wing can have twist, a chord line of the whole wing may not be definable, so an alternate reference line is simply defined. Often, the chord line of the root of the wing is chosen as the reference line. Another choice is to use a horizontal line on the fuselage as the reference line (and also as the longitudinal axis).

Multiple Citizenship
Multiple/dual citizenship (or multiple/dual nationality) is a legal status in which a person is concurrently regarded as a national or citizen of more than one country under the laws of those countries. Conceptually, citizenship is focused on the internal political life of the country and nationality is a matter of international dealings. There is no international convention which determines the nationality or citizenship status of a person. This is defined exclusively by national laws, which can vary and conflict with each other. Multiple citizenship arises because different countries use different, and not necessarily mutually exclusive, criteria for citizenship. Colloquially, people may "hold" multiple citizenship but, technically, each nation makes a claim that a particular person is considered its national. A person holding multiple citizenship is, generally, entitled to the rights of citizenship in each country whose citizenship they are holding (such as right to a passpor ...

Murmansk
Murmansk (Russian: ''Мурманск'' lit. "Norwegian coast"; Finnish: ''Murmansk'', sometimes ''Muurmanski'', previously ''Muurmanni''; Norwegian: ''Norskekysten;'' Northern Sámi: ''Murmánska;'' Kildin Sámi: ''Мурман ланнҍ'') is a port city and the administrative center of Murmansk Oblast in the far northwest part of Russia. It sits on both slopes and banks of a modest ria or fjord, Kola Bay, an estuarine inlet of the Barents Sea. Its bulk is on the east bank of the inlet. It is in the north of the rounded Kola Peninsula which covers most of the oblast. The city is from the border with Norway and from the Finnish border. The city is named for the Murman Coast, which is in turn derived from an archaic term in Russian for "Norwegian". Benefiting from the North Atlantic Current, Murmansk resembles cities of its size across western Russia, with highway and railway access to the rest of Europe, and the northernmost trolleybus system on Earth. It lies over 2° n ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Ministry Of Emergency Situations (Russia)
The Ministry of the Russian Federation for Civil Defence, Emergency Situations and Elimination of Consequences of Natural Disasters (russian: Министерство Российской Федерации по делам гражданской обороны, чрезвычайным ситуациям и ликвидации последствий стихийных бедствий), also known as the Ministry of Emergency Situations (; abbreviated MChS, ) or internationally as EMERCOM (derived from "Emergency Control Ministry"), is a Russian government agency overseeing the civil emergency services in Russia. President Boris Yeltsin established EMERCOM on January 10, 1994, though the ministry can be traced back to December 27, 1990, when the Russian Soviet Federative Socialist Republic (RSFSR) established the Russian Rescue Corps and assigned it the mission of Rapid response team (medicine), rapid response to emergencies.

Mayday (distress Signal)
Mayday is an emergency procedure word used internationally as a distress signal in voice-procedure radio communications. It is used to signal a life-threatening emergency primarily by aviators and mariners, but in some countries local organizations such as firefighters, police forces, and transportation organizations also use the term. Convention requires the word be repeated three times in a row during the initial emergency declaration ("Mayday mayday mayday") to prevent it being mistaken for some similar-sounding phrase under noisy conditions, and to distinguish an ''actual'' mayday call from a message ''about'' a mayday call. History The "mayday" procedure word was conceived as a distress call in the early 1920s by Frederick Stanley Mockford, officer-in-charge of radio at Croydon Airport, England. He had been asked to think of a word that would indicate distress and would easily be understood by all pilots and ground staff in an emergency. Since much of the air traffic at t ...

Flight Recorder
A flight recorder is an electronic recording device placed in an aircraft for the purpose of facilitating the investigation of aviation accidents and incidents. The device may often be referred to as a "black box", an outdated name which has become a misnomer—they are now required to be painted bright orange, to aid in their recovery after accidents. There are two types of flight recording devices: the flight data recorder (FDR) preserves the recent history of the flight through the recording of dozens of parameters collected several times per second; the cockpit voice recorder (CVR) preserves the recent history of the sounds in the cockpit, including the conversation of the pilots. The two devices may be combined into a single unit. Together, the FDR and CVR objectively document the aircraft's flight history, which may assist in any later investigation. The two flight recorders are required by international regulation, overseen by the International Civil Aviation Organizat ...

Ukrayinska Pravda
''Ukrainska Pravda'' ( uk, Українська правда, lit=Ukrainian Truth) is a Ukrainian online newspaper founded by Georgiy Gongadze on 16 April 2000 (the day of the Ukrainian constitutional referendum). Published mainly in Ukrainian with selected articles published in or translated to Russian and English, the newspaper is tailored for a general readership with an emphasis on the politics of Ukraine.
