Ethiopian Airlines Flight 409
Ethiopian Airlines Flight 409 was an international commercial flight scheduled from Beirut to Addis Ababa that crashed into the Mediterranean Sea shortly after takeoff from Rafic Hariri International Airport on 25 January 2010, killing all 90 people on board. This was the first fatal crash for Ethiopian Airlines since the hijack of Ethiopian Airlines Flight 961 in 1996. Aircraft and crew The aircraft involved was a Boeing 737-8AS, registration ET-ANB, s/n 29935. It had its maiden flight on 18 January 2002, and was delivered new to Ryanair on 4 February 2002 as EI-CSW. Stored in , Ethiopian Airlines took delivery of the aircraft on 12 September 2009, leased from CIT Aerospace. Provided with twin CFM56-7B26 powerplants, the airframe last underwent maintenance checks on 25 December 2009 without any technical problems found. It was old at the time the accident took place.

Pilot Error
Pilot error generally refers to an Aviation accidents and incidents, accident in which an action or decision made by the Aircraft pilot#Airline, pilot was the cause or a contributing factor that led to the accident, but also includes the pilot's failure to make a correct decision or take proper action. Errors are intentional actions that fail to achieve their intended outcomes. Chicago Convention on International Civil Aviation, Chicago Convention defines accident as "An occurrence associated with the operation of an aircraft [...] in which [...] a person is fatally or seriously injured [...] ''except when the injuries are [...] inflicted by other persons."'' Hence the definition of the "pilot error" does not include deliberate crash (and such crash is not an accident). The causes of pilot error include psychological and physiological human limitations. Various forms of threat and error management have been implemented into pilot training programs to teach crew members how t ...

Lockheed P-3 Orion
The Lockheed P-3 Orion is a four-engined, turboprop anti-submarine and maritime surveillance aircraft developed for the United States Navy and introduced in the 1960s. Lockheed based it on the L-188 Electra commercial airliner. The aircraft is easily distinguished from the Electra by its distinctive tail stinger or "MAD" boom, used for the (MAD) of submarines. Over the years, the aircraft has seen numerous design developments, most notably in its electronics packages. Nume ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
United Nations Interim Force In Lebanon
The United Nations Interim Force in Lebanon ( ar, قوة الأمم المتحدة المؤقتة في لبنان, he, כוח האו"ם הזמני בלבנון), or UNIFIL ( ar, يونيفيل, he, יוניפי״ל), is a UN peacekeeping mission established on 19 March 1978 by United Nations Security Council Resolutions 425 and 426, to confirm Israeli withdrawal from Lebanon which Israel had invaded five days prior, in order to ensure that the government of Lebanon would restore its effective authority in the area. The 1978 South Lebanon conflict came in the context of Palestinian insurgency in South Lebanon and the Lebanese Civil War. The mandate had to be adjusted twice, due to the Israeli invasion of Lebanon in 1982 and after the Israeli withdrawal from Lebanon in 2000. Following the 2006 Lebanon War, the United Nations Security Council enhanced UNIFIL and decided that in addition to the original mandate, it would, among other things, monitor the cessation of hosti ...

Lebanese Navy
The Lebanese Navy ( ar, القوات البحرية اللبنانية ''Al-qūwātu al-Baḥriyya al-Lubnāniyya'', literally "the Lebanese Sea Forces") is the Navy of the Lebanese Armed Forces. It was formed in 1950 and based in Beirut Naval Base, Lebanon's first naval base. The navy, which currently lacks the proper number of equipment, has a number of approximately 69 vessels of various sizes and roles; however, the navy is trying to modernize itself, and increase its size. The flag of the Lebanese navy depicts a Phoenician ship with the Lebanese Cedar tree, positioned on an anchor above the Arabic inscription of the navy's name. The Lebanese government approved on January 16, 2009, a request by the Lebanese Ministry of Defense to build a new naval base on the shores of Nahr el-Bared Palestinian refugee camp in northern Lebanon. Equipment Current fleet list On February 19, 2015, the Saudi press agency quoted on a Saudi official that Saudi Arabia had halted the $3 billion pro ...

Sikorsky S-61
The Sikorsky S-61L and S-61N are civil variants of the Sikorsky SH-3 Sea King, SH-3 Sea King military helicopter. It was developed and produced by the American helicopter manufacturer Sikorsky Aircraft. The commercial version of the Sea King was developed during the late 1950s. Two versions, the land-based ''S-61L'' and the amphibious ''S-61N'', were created. The S-61L had an enlarged cabin and dispensed with some of the amphibious features, such as its floatplane, float stabilizers, for greater payload capacity. It was considered attractive to utility operators, while the amphibious S-61N appealed to off-shore operators. The first models were delivered to customers during September 1961. By the turn of the century, they had become two of the most widely used airliner and oil rig support helicopters built.Frawley 2003, p. 194. Airliners were a key customer for the S-61L. Los Angeles Airways, New York Airways, and Chicago Helicopter Airways were among the first operators. Howeve ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Eastern European Time
Eastern European Time (EET) is one of the names of UTC+02:00 time zone, 2 hours ahead of Coordinated Universal Time. The zone uses daylight saving time, so that it uses UTC+03:00 during the summer. A number of African countries use UTC+02:00 all year long, where it is called Central Africa Time (CAT), although Egypt and Libya also use the term ''Eastern European Time''. The most populous city in the Eastern European Time zone is Cairo, with the most populous EET city in Europe being Athens. Usage The following countries, parts of countries, and territories use Eastern European Time all year round: * Egypt, since 21 April 2015; used EEST ( UTC+02:00; UTC+03:00 with daylight saving time) from 1988–2010 and 16 May–26 September 2014. See also Egypt Standard Time. * Kaliningrad Oblast (Russia), since 26 October 2014; also used EET in years 1945 and 1991–2011. See also Kaliningrad Time. * Libya, since 27 October 2013; switched from Central European Time, which was u ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Radar
Radar is a detection system that uses radio waves to determine the distance (''ranging''), angle, and radial velocity of objects relative to the site. It can be used to detect aircraft, ships, spacecraft, guided missiles, motor vehicles, weather formations, and terrain. A radar system consists of a transmitter producing electromagnetic waves in the radio or microwaves domain, a transmitting antenna, a receiving antenna (often the same antenna is used for transmitting and receiving) and a receiver and processor to determine properties of the objects. Radio waves (pulsed or continuous) from the transmitter reflect off the objects and return to the receiver, giving information about the objects' locations and speeds. Radar was developed secretly for military use by several countries in the period before and during World War II. A key development was the cavity magnetron in the United Kingdom, which allowed the creation of relatively small systems with sub-meter resolution. Th ...

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 ...

Thunderstorm
A thunderstorm, also known as an electrical storm or a lightning storm, is a storm characterized by the presence of lightning and its acoustic effect on the Earth's atmosphere, known as thunder. Relatively weak thunderstorms are sometimes called thundershowers. Thunderstorms occur in a type of cloud known as a cumulonimbus. They are usually accompanied by strong winds and often produce heavy rain and sometimes snow, sleet, or hail, but some thunderstorms produce little precipitation or no precipitation at all. Thunderstorms may line up in a series or become a rainband, known as a squall line. Strong or severe thunderstorms include some of the most dangerous weather phenomena, including large hail, strong winds, and tornadoes. Some of the most persistent severe thunderstorms, known as supercells, rotate as do cyclones. While most thunderstorms move with the mean wind flow through the layer of the troposphere that they occupy, vertical wind shear sometimes causes a de ...

Wind Speed
In meteorology, wind speed, or wind flow speed, is a fundamental atmospheric quantity caused by air moving from high to low pressure, usually due to changes in temperature. Wind speed is now commonly measured with an anemometer. Wind speed affects weather forecasting, aviation and maritime operations, construction projects, growth and metabolism rate of many plant species, and has countless other implications. Note that wind direction is usually almost parallel to isobars (and not perpendicular, as one might expect), due to Earth's rotation. Units Metres per second (m/s) is the SI unit for velocity and the unit recommended by the World Meteorological Organization for reporting wind speeds, and is amongst others used in weather forecasts in the Nordic countries. Since 2010 the International Civil Aviation Organization (ICAO) also recommends meters per second for reporting wind speed when approaching runways, replacing their former recommendation of using kilometres per h ...
