Icelandic Airlines Flight LL 001
Loftleiðir Icelandic Airlines Flight 001, a charter flight, was a Douglas DC-8 that crashed on 15 November 1978, on approach to the international airport in Colombo, Sri Lanka. The crash killed 8 of the 13 Icelandic crew members, 5 reserve crew members, and 170 (mostly Indonesian) Muslim pilgrims from South Borneo out of a total of 262 passengers and crew. The official report by Sri Lankan authorities determined the probable cause of the crash to be failure of the crew to conform to approach procedures; however, American and Icelandic authorities claimed faulty equipment at the airport and air traffic control error as the reasons for the crash. With 183 fatalities, the crash of Flight LL001 is the deadliest crash involving an Icelandic airline, and the second deadliest in Sri Lankan aviation history after Martinair Flight 138, another chartered DC-8, which crashed four years earlier.

Controlled Flight Into Terrain
In aviation, a controlled flight into terrain (CFIT; usually ) is an aviation accidents and incidents, accident in which an airworthy aircraft, under aircraft pilot, pilot control, is unintentionally flown into the ground, a mountain, a body of water or an obstacle. In a typical CFIT scenario, the aircrew, crew is unaware of the impending disaster until it is too late. The term was coined by engineers at Boeing in the late 1970s. Accidents where the aircraft is out of control at the time of impact, because of mechanical failure or pilot error, are not considered CFIT (they are known as ''uncontrolled flight into terrain'' or ''UFIT''), nor are incidents resulting from the deliberate action of the person at the controls, such as acts of terrorism or suicide by pilot. According to Boeing in 1997, CFIT was a leading cause of airplane accidents involving the loss of life, causing over 9,000 deaths since the beginning of the commercial jet aircraft. CFIT was identified as a cause of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Muslim
Muslims ( ar, المسلمون, , ) are people who adhere to Islam, a monotheistic religion belonging to the Abrahamic tradition. They consider the Quran, the foundational religious text of Islam, to be the verbatim word of the God of Abraham (or '' Allah'') as it was revealed to Muhammad, the main Islamic prophet. The majority of Muslims also follow the teachings and practices of Muhammad ('' sunnah'') as recorded in traditional accounts (''hadith''). With an estimated population of almost 1.9 billion followers as of 2020 year estimation, Muslims comprise more than 24.9% of the world's total population. In descending order, the percentage of people who identify as Muslims on each continental landmass stands at: 45% of Africa, 25% of Asia and Oceania (collectively), 6% of Europe, and 1% of the Americas. Additionally, in subdivided geographical regions, the figure stands at: 91% of the Middle East–North Africa, 90% of Central Asia, 65% of the Caucasus, 42% of Southeast As ...

Radar Control
Radar control is a method of providing air traffic control services with the use of radar and Automatic Dependent Surveillance (ADS–B). The provision of air traffic control services without the use of radar is called procedural control. Separation In air traffic control, the risk of aircraft colliding is managed by applying separation rules. These rules require aircraft to be separated by either a minimum vertical distance, or, if for some reason they cannot be separated vertically, by a minimum horizontal distance defined by various means. One of the means of determining horizontal separation is by a controller observing the radar returns of the aircraft to be at least a minimum horizontal distance apart. This is the essence of radar control, and is known as ''radar separation''. Standard radar separation varies from airspace to airspace and country to country, however 3 nms in terminal airspace and 5 nms in en route ''En route'' may refer to: * ''En Route'' (no ...

Instrument Landing System
In aviation, the instrument landing system (ILS) is a precision radio navigation system that provides short-range guidance to aircraft to allow them to approach a runway at night or in bad weather. In its original form, it allows an aircraft to approach until it is over the ground, within a of the runway. At that point the runway should be visible to the pilot; if it is not, they perform a missed approach. Bringing the aircraft this close to the runway dramatically increases the range of weather conditions in which a safe landing can be made. Other versions of the system, or "categories", have further reduced the minimum altitudes, runway visual ranges (RVRs), and transmitter and monitoring configurations designed depending on the normal expected weather patterns and airport safety requirements. ILS uses two directional radio signals, the ''localizer'' (108 to 112 MHz frequency), which provides horizontal guidance, and the ''glideslope'' (329.15 to 335 MHz frequency ...

Runway
According to the International Civil Aviation Organization (ICAO), a runway is a "defined rectangular area on a land aerodrome prepared for the landing and takeoff of aircraft". Runways may be a man-made surface (often asphalt concrete, asphalt, concrete, or a mixture of both) or a natural surface (sod, grass, soil, dirt, gravel, ice, sand or road salt, salt). Runways, as well as taxiways and Airport apron, ramps, are sometimes referred to as "tarmac", though very few runways are built using Tarmacadam, tarmac. Takeoff and landing areas defined on the surface of water for seaplanes are generally referred to as waterways. Runway lengths are now International Civil Aviation Organization#Use of the International System of Units, commonly given in meters worldwide, except in North America where feet are commonly used. History In 1916, in a World War I war effort context, the first concrete-paved runway was built in Clermont-Ferrand in France, allowing local company Michelin to ...

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] |
Jeddah, Saudi Arabia
Jeddah ( ), also spelled Jedda, Jiddah or Jidda ( ; ar, , Jidda, ), is a city in the Hejaz region of the Kingdom of Saudi Arabia (KSA) and the country's commercial center. Established in the 6th century BC as a fishing village, Jeddah's prominence grew in 647 when the Caliphate, Caliph Uthman, Osman made it a major port for Indian Ocean trade routes, channelling goods to Mecca, and to serve Muslims, Muslim travelers for Islamic pilgrimage. Since those times, Jeddah has served as the gateway for millions of pilgrims who have arrived in Saudi Arabia, traditionally by sea and recently by air.

Loftleiðir
Loftleiðir HF, internationally known as Icelandic Airlines (abbreviated IAL) or Loftleiðir Icelandic, was a private Icelandic airline headquartered on the grounds of Reykjavík Airport in Reykjavík, which operated mostly trans-atlantic flights linking Europe and America, pioneering the low-cost flight business strategy on these routes. History Loftleiðir Loftleiðir (the name being a compound of the Icelandic words for ''Air'' and ''Way'') was founded on 10 March 1944, by Alfreð Elíasson and two other young Icelandic pilots who had just returned from flight training in Canada. The first revenue flight (from Reykjavík to Ísafjörður) took place on 6 April of that year. During the initial years, only domestic routes out of Reykjavík Airport were operated using airplanes of the types Douglas DC-3, Consolidated PBY Catalina,Hall ''Air Pictorial'' September 1971, p. 344.

Martinair Flight 138
Martinair Flight 138 was a chartered flight from Surabaya, East Java, Indonesia, to Colombo, Sri Lanka. The aircraft was operated by the Dutch airline Martinair on behalf of Garuda Indonesia. On 4 December 1974, the aircraft, a McDonnell Douglas DC-8-55CF, crashed into a mountain shortly before landing, killing all 191 people aboard – 182 Indonesian hajj pilgrims bound for Mecca, and nine crew members. The crash remains the deadliest in Sri Lankan aviation history and the third-deadliest involving a DC-8, after Arrow Air Flight 1285 and Nigeria Airways Flight 2120. At the time, it was the second-deadliest aviation accident in history, after the loss of Turkish Airlines Flight 981 which occurred earlier that same year. Flight 138 departed Juanda International Airport in Surabaya at approximately 12.03 UTC, with a stopover at Bandaranaike Airport in Colombo. At around 16.30 UTC air traffic control in Colombo cleared the flight. At 16.38 UTC another air traffic controller is ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
