Sol Líneas Aéreas Flight 5428
Sol Líneas Aéreas Flight 5428 was a passenger flight which crashed near Los Menucos, Argentina, on 18 May 2011, killing all 22 people on board. The aircraft involved, a Saab 340, was operating Sol Líneas Aéreas' scheduled domestic service from Neuquén to Comodoro Rivadavia. The following investigation concluded that severe airframe icing had led to a loss of control from which the crew was unable to recover. The crash is the deadliest aviation accident involving a Saab 340. History of the flight Flight 5428 had taken off from Rosario International Airport at 17:35 local time (20:35 UTC) on 18 May bound for Comodoro Rivadavia Airport. The service was scheduled to stop over at Córdoba, Mendoza and Neuquén. After completing uneventfully the first three segments, the Saab 340 took off from Presidente Perón International Airport in Neuquén at 20:05 for its final leg. At around 20:29, while climbing toward its assigned flight level FL190 (), the aircraft encountered icin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Loss Of Control (aeronautics)
In aeronautics, loss of control (LOC) is the unintended departure of an aircraft from controlled flight and is a significant factor in several Aviation accidents and incidents, aviation accidents worldwide. In 2015 it was the leading cause of general aviation accidents. Loss of control may be the result of mechanical failure, external disturbances, aircraft upset conditions, or inappropriate crew actions or responses. Causes Loss of control causes aircraft to depart from normal flight and possibly reach altitudes or encounter situations from which it can be difficult or impossible to recover, such as a Stall (fluid dynamics), stall or a Spin (aerodynamics), spin. Due to the certification and design processes, it is extremely rare for aircraft to experience a loss of control without extreme mishandling or a technical defect. A NASA study focused on identifying causal factors and addressing mitigation challenges related to aircraft loss of control had developed a preliminary list o ...

Saab 340
The Saab 340 is a Swedish twin-engine turboprop aircraft designed and initially produced by Saab AB and Fairchild Aircraft. It is designed to seat 30–36 passengers and, as of July 2018, there were 240 operational aircraft used by 34 different operators. Under the production arrangement in which production was split 65:35 between Saab and Fairchild, Saab constructed the all-aluminum fuselage and vertical stabilizer along with final assembly of the aircraft in Linköping, Sweden, while Fairchild was responsible for the wings, empennage, and wing-mounted nacelles for the two turboprop engines. After Fairchild ceased this work in 1985, production of these components was transferred to Sweden. On 25 January 1983, the Saab 340 conducted its maiden flight. During the early 1990s, an enlarged derivative of the airliner, designated as the Saab 2000, was introduced. However, sales of the type declined due to intense competition within the regional aircraft market. Saab decided to cea ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Air Carrier
An airline is a company that provides air transport services for traveling passengers or freight (cargo). Airlines use aircraft to supply these services and may form partnerships or alliances with other airlines for codeshare agreements, in which they both offer and operate the same flight. Generally, airline companies are recognized with an air operating certificate or license issued by a governmental aviation body. Airlines may be scheduled or charter operators. The first airline was the German airship company DELAG, founded on November 16, 1909. The four oldest non-airship airlines that still exist are the Netherlands' KLM (1919), Colombia's Avianca (1919), Australia's Qantas (1920) and the Russian Aeroflot (1923). Airline ownership has seen a shift from mostly personal ownership until the 1930s to government-ownership of major airlines from the 1940s to 1980s and back to large-scale privatization following the mid-1980s. Since the 1980s, there has been a trend of maj ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Northwest Airlink
Northwest Airlink was the brand name of Northwest Airlines' regional airline service, which flew turboprop and regional jet aircraft from Northwest's domestic hubs in Minneapolis, Detroit, and Memphis. Service was primarily to small-to-medium-sized cities and towns where larger aircraft might not be economical to operate and also to larger markets to either provide additional capacity or more frequent flights than could be justified using mainline aircraft. The Northwest Airlink trade name was replaced by the Delta Connection trade name for Delta Air Lines following the Delta/Northwest merger. History Northwest Airlink was formed in December 1984 when Northwest Airlines took steps to enhance its domestic services by entering a marketing agreement with Mesaba Airlines. Mesaba was the dominant airline serving Minneapolis/St Paul at the time. Under the agreement, Mesaba would operate as Northwest Orient Airlink. Mesaba initially operated commuter and regional turboprop aircraft. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Aircraft Registration
An aircraft registration is a code unique to a single aircraft, required by international convention to be marked on the exterior of every civil aircraft. The registration indicates the aircraft's country of registration, and functions much like an automobile license plate or a ship registration. This code must also appear in its Certificate of Registration, issued by the relevant civil aviation authority (CAA). An aircraft can only have one registration, in one jurisdiction, though it is changeable over the life of the aircraft. Legal provisions In accordance with the Convention on International Civil Aviation (also known as the Chicago Convention), all civil aircraft must be registered with a civil aviation authority (CAA) using procedures set by each country. Every country, even those not party to the Chicago Convention, has an NAA whose functions include the registration of civil aircraft. An aircraft can only be registered once, in one jurisdiction, at a time. The NAA a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Comair (USA)
Comair was a regional airline in the United States, a wholly owned subsidiary of Delta Air Lines, headquartered at Cincinnati/Northern Kentucky International Airport in Boone County, Kentucky, Boone County, Kentucky, United States. Operating under the brand name Delta Connection, Comair operated passenger services to destinations in the United States, Canada, Mexico and the Bahamas. At the height of its operations in the 1990s and early 2000s, it was the world's largest regional airline, and operated from 1977 until 2012. History The airline was established in March 1977, and started operations in April 1977. Patrick J. Sowers, Robert T. Tranter, David Mueller and his father Raymond founded the airline in Cincinnati. At the end of its first year of highly profitable operations, two of the company founders, Sowers and Tranter, abruptly resigned the day following the first annual meeting as a "demand for immediate change" after they had uncovered repeated unacceptable and unsaf ...

Mayday
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"). 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 the time was between Croydon and Le Bourget Airport in Paris, he proposed the term "mayday", the phonetic equivalent of the French (a short form of , "come ndhelp me") ...

Instrument Meteorological Conditions
In aviation, instrument meteorological conditions (IMC) are weather conditions that require pilots to fly primarily by reference to flight instruments, and therefore under instrument flight rules (IFR), as opposed to flying by outside visual references under visual flight rules (VFR). Typically, this means flying in cloud or poor weather, where little or nothing can be seen or recognised when looking out of the window. Simulated IMC can be achieved for training purposes by wearing view-limiting devices, which restrict outside vision and force the trainee to rely on instrument indications only. Distinction from Visual Meteorological Conditions The weather conditions required for flight under VFR are known as visual meteorological conditions (VMC). The boundary criteria between VMC and IMC are known as ''VMC minima''. IMC and VMC are mutually exclusive. In fact, instrument meteorological conditions are defined as less than the minima specified for visual meteorological conditions ...

Flight Level
In aviation, a flight level (FL) is an aircraft's altitude as determined by a pressure altimeter using the International Standard Atmosphere. It is expressed in hundreds of feet or metres. The altimeter setting used is the ISA sea level pressure of 1013 hPa or 29.92 inHg. The actual surface pressure will vary from this at different locations and times. Therefore, by using a standard pressure setting, every aircraft has the same altimeter setting, and vertical clearance can be maintained during cruise flight. Background Flight levels are used to ensure safe vertical separation between aircraft. Historically, altitude has been measured using an altimeter, essentially a calibrated barometer. An altimeter measures ambient air pressure, which decreases with increasing altitude following the barometric formula. It displays the corresponding altitude. If aircraft altimeters were not calibrated consistently, then two aircraft could be flying at the same altitude even thou ...
