1959 Turkish Airlines Gatwick Crash
The 1959 Turkish Airlines Gatwick crash occurred on 17 February 1959, near London Gatwick Airport to a Turkish Airlines Vickers Viscount Type 793 (registration TC-SEV) on an international charter flight from Esenboğa International Airport in Ankara, Turkey, to London Heathrow Airport, however the Viscount diverted to London Gatwick Airport, United Kingdom due to heavy fog. It was carrying the Turkish prime minister and a party of government officials. The Viscount crashed in a wood 3 miles (4.8 km) from the threshold of Gatwick runway during its final approach to land in extensive fog. Five of the eight crew and nine of the 16 passengers died in the crash. The prime minister was among the ten survivors. Flight Turkish Prime Minister Adnan Menderes, accompanied by a Turkish delegation, was on his way to the British capital to sign the London Agreement on the Cyprus issue with British Prime Minister Harold Macmillan and Greek Prime Minister Constantine Karamanlis, which ga ...

Newdigate
Newdigate is a village and civil parish in the Mole Valley borough of Surrey lying in a relatively flat part of the Weald to the east of the A24 road between Dorking and Horsham, ESE of Guildford and south of London. Neighbouring parishes are Charlwood, North Holmwood, South Holmwood, Leigh and Capel. History Etymology The name of Newdigate refers to a place at the gate or path to a wood. Surviving manuscripts such as manorial rolls, Assize Rolls and Feet of Fines give forms including Newdegate (13th century), Newedegate and Neudegate (15th century) and Nudgate (16th century). The name ''Ewood'' (''Iwode'' in Feet of Fines 1312) occurs in the parish and might derive from Old English for a forest of yew-trees, in which case the 'N' survives from a prefix such as 'in' (''O.E.'' 'on') or 'at the' (''O.E.'' 'be þane'). Alternatively, the word may refer to a 'New wood'. Early history In early history Newdigate was at the western heart of the Weald a much more dense w ...

Harold Macmillan
Maurice Harold Macmillan, 1st Earl of Stockton, (10 February 1894 – 29 December 1986) was a British Conservative statesman and politician who was Prime Minister of the United Kingdom from 1957 to 1963. Caricatured as "Supermac", he was known for his pragmatism, wit and unflappability. Macmillan was badly injured as an infantry officer during the First World War. He suffered pain and partial immobility for the rest of his life. After the war he joined his family book-publishing business, then entered Parliament at the 1924 general election. Losing his seat in 1929, he regained it in 1931, soon after which he spoke out against the high rate of unemployment in Stockton-on-Tees. He opposed the appeasement of Germany practised by the Conservative government. He rose to high office during the Second World War as a protégé of Prime Minister Winston Churchill. In the 1950s Macmillan served as Foreign Secretary and Chancellor of the Exchequer under Anthony Eden. When ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Oktas
In meteorology, an okta is a unit of measurement used to describe the amount of cloud cover at any given location such as a weather station. Sky conditions are estimated in terms of how many eighths of the sky are covered in cloud, ranging from 0 oktas (completely clear sky) through to 8 oktas (completely overcast). In addition, in the SYNOP code there is an extra cloud cover indicator '9' indicating that the sky is totally obscured (i.e. hidden from view), usually due to dense fog or heavy snow. When used in weather charts, okta measurements are shown by means of graphic symbols (rather than numerals) contained within weather circles, to which are attached further symbols indicating other measured data such as wind speed and wind direction. Although relatively straightforward to measure (visually, for instance, by using a mirror), oktas only estimate cloud cover in terms of the area of the sky covered by clouds. They do not account for cloud type or thickness, and this limits ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Visibility
The visibility is the measure of the distance at which an object or light can be clearly discerned. In meteorology it depends on the transparency of the surrounding air and as such, it is unchanging no matter the ambient light level or time of day. It is reported within surface weather observations and METAR code either in meters or statute miles, depending upon the country. Visibility affects all forms of traffic: roads, sailing and aviation. The geometric range of vision is limited by the curvature of the earth and depends on the eye level and the height of the object being viewed. In geodesy, the atmospheric refraction must be taken into account when calculating geodetic visibility. Meteorological visibility Definition ICAO Annex 3 ''Meteorological Service for International Air Navigation'' contains the following definitions and note: :a) the greatest distance at which a black object of suitable dimensions, situated near the ground, can be seen and recognized when o ...

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 ...

Terminal Control Center
Air traffic control (ATC) is a service provided by ground-based air traffic controllers who direct aircraft on the ground and through a given section of controlled airspace, and can provide advisory services to aircraft in non-controlled airspace. The primary purpose of ATC worldwide is to prevent collisions, organize and expedite the flow of air traffic, and provide information and other support for pilots. Air traffic controllers monitor the location of aircraft in their assigned airspace by radar and communicate with the pilots by radio. To prevent collisions, ATC enforces traffic separation rules, which ensure each aircraft maintains a minimum amount of empty space around it at all times. In many countries, ATC provides services to all private, military, and commercial aircraft operating within its airspace. Depending on the type of flight and the class of airspace, ATC may issue ''instructions'' that pilots are required to obey, or ''advisories'' (known as ''flight inform ...

Mayfield, East Sussex
Mayfield and Five Ashes is a civil parish in the High Weald of East Sussex, England. The two villages making up the principal part of the parish lie on the A267 road between Royal Tunbridge Wells and Eastbourne: Mayfield, the larger of the two villages is ten miles (16 km) south of Royal Tunbridge Wells; with Five Ashes being 2.5 miles (4 km) further south. Mayfield village Every September the village hosts its annual carnival. This is to commemorate the Protestants being condemned here on 23 September 1556, and being burnt at the stake in Lewes. The festival is part of the Sussex bonfire tradition of marking the discovery of the Gunpowder Plot. The procession marches through the village by torchlight on the third Saturday in September, climaxing with a firework display in the recreation ground. The money raised through the street collection is spent on charities. Governance Mayfield and Five Ashes Civil Parish falls within the electoral ward simply called ...

Holding (aeronautics)
In aviation, holding (or flying a hold) is a maneuver designed to delay an aircraft already in flight while keeping it within a specified airspace. Implementation A holding pattern for instrument flight rules (IFR) aircraft is usually a racetrack pattern based on a ''holding fix''. This ''fix'' can be a radio beacon such as a non-directional beacon (NDB) or VHF omnidirectional range (VOR). The fix is the start of the first turn of the racetrack pattern. Aircraft will fly towards the fix, and once there will enter a predefined racetrack pattern. A standard holding pattern uses right-hand turns and takes approximately 4 minutes to complete (one minute for each 180-degree turn, and two one-minute straight ahead sections). Deviations from this pattern can happen if long delays are expected; longer legs (usually two or three minutes) may be used, or aircraft with distance measuring equipment (DME) may be assigned patterns with legs defined in nautical miles rather than minutes. ...

Low Frequency Radio Range
The low-frequency radio range, also known as the four-course radio range, LF/MF four-course radio range, A-N radio range, Adcock radio range, or commonly "the range", was the main navigation system used by aircraft for instrument flying in the 1930s and 1940s, until the advent of the VHF omnidirectional range (VOR), beginning in the late 1940s. It was used for en route navigation as well as instrument approaches and holds. Based on a network of radio towers which transmitted directional radio signals, the radio range defined specific airways in the sky. Pilots navigated using low-frequency radio by listening to a stream of automated "A" and "N" Morse codes. For example, they would turn the aircraft to the right when hearing an "N" stream ("dah-dit, dah-dit, ..."), to the left when hearing an "A" stream ("di-dah, di-dah, ..."), and fly straight ahead while hearing a steady tone. As the VOR system was phased in around the world, low-frequency radio range was gradually phased ou ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Epsom
Epsom is the principal town of the Borough of Epsom and Ewell in Surrey, England, about south of central London. The town is first recorded as ''Ebesham'' in the 10th century and its name probably derives from that of a Saxon landowner. The earliest evidence of human activity is from the mid-Bronze Age, but the modern settlement probably grew up in the area surrounding St Martin's Church in the 6th or 7th centuries and the street pattern is thought to have become established in the Middle Ages. Today the High Street is dominated by the clock tower, which was erected in 1847–8. Like other nearby settlements, Epsom is located on the spring line where the permeable chalk of the North Downs meets the impermeable London Clay. Several tributaries of the Hogsmill River rise in the town and in the 17th and early 18th centuries, the spring on Epsom Common was believed to have healing qualities. The mineral waters were found to be rich in ''Epsom salts'', which were later identif ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Airspace
Airspace is the portion of the atmosphere controlled by a country above its territory, including its territorial waters or, more generally, any specific three-dimensional portion of the atmosphere. It is not the same as aerospace, which is the general term for Earth's atmosphere and the outer space in its vicinity. Within the United States: * Controlled airspace exists where it is deemed necessary that air traffic control has some form of positive executive control over aircraft flying in that airspace (however, air traffic control does not necessarily control traffic operating under visual flight rules (VFR) within this airspace). Airspace may be further subdivided into a variety of areas and zones, including those where there are either restrictions on flying activities or complete prohibition of flying activities. Horizontal boundary By international law, a state "has complete and exclusive sovereignty over the airspace above its territory", which corresponds with t ...
