ICAO airport code
–
The ICAO airport code or location indicator is a four-character alphanumeric code designating aerodromes around the world. ICAO codes are used to identify other aviation facilities such as weather stations, International Flight Service Stations or Area Control Centers. Flight information regions are identified by a unique ICAO-code. Code selections in North America were based on existing radio station identifiers, for example, radio stations in Canada were already starting with C, so it seemed logical to begin Canadian airport identifiers with Cxxx. The United States had many pre-existing airports with established mnemonic codes and their ICAO codes were formed simply by prepending a K to the existing codes, as half the radio station identifiers in the US began with K. Most ICAO codes outside the US and Canada have a geographical structure. Most of the rest of the world was classified in a more planned top-down manner, thus Uxxx referred to the Soviet Union with the second letter denoting the specific region within it, and so forth. Europe had too many locations for one starting letter, so it was split into Exxx for northern Europe. The second letter was more specific, EGxx was the United Kingdom, EDxx was West Germany, ETxx was East Germany, LExx was Spain, LAxx was Albania, France was designated LFxx, as the counterpart EFxx was the unambiguously northern Finland. ICAO codes are separate and different from IATA codes, which are used for airline timetables, reservations. For example, the IATA code for Londons Heathrow Airport is LHR, in general IATA codes are usually derived from the name of the airport or the city it serves, while ICAO codes are distributed by region and country. Far more aerodromes have ICAO codes than IATA codes, and to add to the confusion IATA codes are assigned to railway stations. Unlike the IATA codes, the ICAO codes generally have a structure and are comprehensive. In general, the first letter is allocated by continent and represents a country or group of countries within that continent, the second letter generally represents a country within that region, and the remaining two are used to identify each airport. The exception to rule is larger countries that have single-letter country codes. In either case, ICAO codes generally provide geographical context unlike IATA codes, for example, if one knows that the ICAO code for Heathrow is EGLL, then one can deduce that the airport EGGP is somewhere in the UK. On the other hand, knowing that the IATA code for Heathrow is LHR does not enable one to deduce the location of the airport LHV with any greater certainty, there are a few exceptions to the regional structure of the ICAO code made for political or administrative reasons. Similarly Saint Pierre and Miquelon is controlled by France, and airports there are assigned LFxx as though they were in Europe, further, in region L, all available 2-letter prefixes have been exhausted and thus no additional countries can be added

Armed Forces of Saudi Arabia
–
The Royal Saudi Arabian Armed Forces consists of the Saudi Arabian Army, the Royal Saudi Air Force, the Royal Saudi Navy, the Royal Saudi Air Defense, and the Royal Saudi Strategic Missile Force. In addition the Saudi Arabian National Guard, which is one of the three branches of the Joint Forces of the Kingdom. The national guard is under the control of the Ministry of National Guard, instead of the Ministry of Defence, the Saudi Arabian Royal Guard. Kingdom of Saudi Arabia has one of the defence forces in the Middle East. The kingdom spends 25% of its budget, or about $88 billion, on its military, in terms of manpower, Saudi Arabia has about 688,000 active personnel in its military, with 300,000 army troops. Saudi Arabia also has more than 200,000 men in its national guard and 25,000 tribal levies, the navy has about 60,000 members, air defense forces and strategic rocket forces about 40,000 soldiers. In addition to the air forces with more than 63,000 active employees, also there is an intelligence service. The Saudi Arabian National Guard is not a reserve but a fully operational force, and originated out of Abdul Azizs tribal military-religious force. Its modern existence, however, is attributable to it being effectively Abdullahs private army since the 1960s and, crown Prince Sultan bin Abdulaziz was Saudi Arabias Minister of Defence and Aviation from 1962 to 2011. The vice minister, Abdulrahman bin Abdulaziz, was his full brother and his oldest son, Khalid bin Sultan, was appointed assistant minister in 2001 and was in office until April 2013. In 1987, members of the air force, army, and navy are mainly recruits from groups of people without a strong identity from the Nejd tribal system, spending on defense and security has increased significantly since the mid-1990s and was about US$67 billion in 2013. Saudi Arabia ranks among the top five nations in the world in government spending for its military and its modern, high-technology arsenal makes Saudi Arabia among the worlds most densely armed nations, with its military equipment being supplied primarily by the United States, France, and Britain. According to SIPRI, in 2010–14 Saudi Arabia became the second largest arms importer. Major imports in 2010–14 included 45 combat aircraft from the UK,38 combat helicopters from the USA,4 tanker aircraft from Spain and over 600 armoured vehicles from Canada. Saudi Arabia has a long list of outstanding orders for arms, including 27 more combat aircraft from the UK,154 combat aircraft from the USA, the United States sold more than $80 billion in military hardware between 1951 and 2006 to the Saudi military. In comparison, the Israel Defense Forces received $53.6 billion in U. S. military grants between 1949 and 2007. On 20 October 2010, U. S. State Department notified Congress of its intention to make the biggest arms sale in American history—an estimated $60.5 billion purchase by the Kingdom of Saudi Arabia. The package represented an improvement in the offensive capability of the Saudi armed forces

Royal Saudi Air Force
–
The Royal Saudi Air Force, is the aviation branch of the Saudi Arabian armed forces. The RSAF has developed from a defensive military force into one with an advanced offensive capability. The RSAF maintains the third largest fleet of F-15s after the American, the backbone of the RSAF is currently the Boeing F-15 Eagle, with the Panavia Tornado also forming a major component. The Tornado and many aircraft were delivered under the Al Yamamah contracts with British Aerospace. The RSAF ordered various weapons in the 1990s, including Sea Eagle anti-ship missiles, laser-guided bombs, al-Salam, a successor to the Al Yamamah agreement will see 72 Eurofighter Typhoons delivered by BAE. The RSAF was formed in the mid-1920s with British assistance and it was re-organized in 1950 and began to receive American assistance from 1952 including the use of Dhahran Airfield by the United States Air Force. The Saudi forces are equipped with mainly western hardware, main suppliers are companies in the United Kingdom and the United States of America. Both the UK and the US are involved in training programs conducted in Saudi Arabia, during the 1980s and 1990s, by Middle Eastern standards the armed forces of Saudi Arabia were relatively small. Its strength however was derived from advanced technology, aircraft training is executed on the Pilatus PC-9, BAe Hawk, Boeing F-15D Eagle and the Northrop F-5F Tiger II. The C-130 Hercules is the mainstay of the fleet and the Hercules is assisted by CASA CN-235s. Reconnaissance is performed by 17 Squadron with its RF-5E and the Boeing E-3A is the Airborne Early Warning platform operated by 18 Squadron. The VIP support fleet consists of a variety of civil registered aircraft such as the Boeing 707,737 and 747, Lockheed Tri-Stars, MD11s. Nonetheless, the RSAF announced its intention to purchase the Typhoon from BAE Systems in December 2005, on 18 August 2006 a memorandum of understanding was signed for 72 aircraft in a GB£6–10 billion deal. Following this order, the investigation of the Al Yamamah contract was suppressed by the British Prime minister Tony Blair in December 2006, on 17 September 2007 Saudi Arabia announced it had signed a £4. 4bn deal with BAE Systems for 72 Typhoons. On 29 December 2011, the United States signed a $29.4 billion deal to sell 84 F-15s in the SA configuration, the sale includes upgrades for the older F-15s up to the SA standard and related equipment and services. On 23 May 2012, British defence firm BAE Systems is to sell 22 BAE Hawk advanced jet aircraft to the Royal Saudi Air Force for a total of £1.9 billion. The deal also includes simulators, ground and training equipment and spares, on April 2013, British defence firm BAE Systems delivers the first two new Typhoons of 24 to Saudi Arabia. In 2013, the USAF tendered for security services to protect the Saudi air force from Cyberwarfare, on 12 August 2009, UPI reported that Saudi Arabia was seeking upgrades for their E-3 fleet and aerial refuelling tanker aircraft

Saudi Arabia
–
Saudi Arabia is bordered by Jordan and Iraq to the north, Kuwait to the northeast, Qatar, Bahrain and the United Arab Emirates to the east, Oman to the southeast and Yemen to the south. It is separated from Israel and Egypt by the Gulf of Aqaba and it is the only nation with both a Red Sea coast and a Persian Gulf coast and most of its terrain consists of arid desert and mountains. The area of modern-day Saudi Arabia formerly consisted of four regions, Hejaz, Najd and parts of Eastern Arabia. The Kingdom of Saudi Arabia was founded in 1932 by Ibn Saud and he united the four regions into a single state through a series of conquests beginning in 1902 with the capture of Riyadh, the ancestral home of his family, the House of Saud. Saudi Arabia has since been a monarchy, effectively a hereditary dictatorship governed along Islamic lines. The ultraconservative Wahhabi religious movement within Sunni Islam has been called the predominant feature of Saudi culture, with its global spread largely financed by the oil and gas trade. Saudi Arabia is sometimes called the Land of the Two Holy Mosques in reference to Al-Masjid al-Haram and Al-Masjid an-Nabawi, the state has a total population of 28.7 million, of which 20 million are Saudi nationals and 8 million are foreigners. The states official language is Arabic, petroleum was discovered on 3 March 1938 and followed up by several other finds in the Eastern Province. Saudi Arabia has since become the worlds largest oil producer and exporter, controlling the second largest oil reserves. The kingdom is categorized as a World Bank high-income economy with a high Human Development Index and is the only Arab country to be part of the G-20 major economies. However, the economy of Saudi Arabia is the least diversified in the Gulf Cooperation Council, the state has attracted criticism for its treatment of women and use of capital punishment. Saudi Arabia is an autocracy, has the fourth highest military expenditure in the world. Saudi Arabia is considered a regional and middle power, in addition to the GCC, it is an active member of the Organisation of Islamic Cooperation and OPEC. Following the unification of the Hejaz and Nejd kingdoms, the new state was named al-Mamlakah al-ʻArabīyah as-Suʻūdīyah by royal decree on 23 September 1932 by its founder, Abdulaziz Al Saud. Although this is translated as the Kingdom of Saudi Arabia in English it literally means the Saudi Arab kingdom. Its inclusion expresses the view that the country is the possession of the royal family. Al Saud is an Arabic name formed by adding the word Al, meaning family of or House of, in the case of the Al Saud, this is the father of the dynastys 18th century founder, Muhammad bin Saud. There is evidence that human habitation in the Arabian Peninsula dates back to about 125,000 years ago

Geographic coordinate system
–
A geographic coordinate system is a coordinate system used in geography that enables every location on Earth to be specified by a set of numbers, letters or symbols. The coordinates are chosen such that one of the numbers represents a vertical position. A common choice of coordinates is latitude, longitude and elevation, to specify a location on a two-dimensional map requires a map projection. The invention of a coordinate system is generally credited to Eratosthenes of Cyrene. Ptolemy credited him with the adoption of longitude and latitude. Ptolemys 2nd-century Geography used the prime meridian but measured latitude from the equator instead. Mathematical cartography resumed in Europe following Maximus Planudes recovery of Ptolemys text a little before 1300, in 1884, the United States hosted the International Meridian Conference, attended by representatives from twenty-five nations. Twenty-two of them agreed to adopt the longitude of the Royal Observatory in Greenwich, the Dominican Republic voted against the motion, while France and Brazil abstained. France adopted Greenwich Mean Time in place of local determinations by the Paris Observatory in 1911, the latitude of a point on Earths surface is the angle between the equatorial plane and the straight line that passes through that point and through the center of the Earth. Lines joining points of the same latitude trace circles on the surface of Earth called parallels, as they are parallel to the equator, the north pole is 90° N, the south pole is 90° S. The 0° parallel of latitude is designated the equator, the plane of all geographic coordinate systems. The equator divides the globe into Northern and Southern Hemispheres, the longitude of a point on Earths surface is the angle east or west of a reference meridian to another meridian that passes through that point. All meridians are halves of great ellipses, which converge at the north and south poles, the prime meridian determines the proper Eastern and Western Hemispheres, although maps often divide these hemispheres further west in order to keep the Old World on a single side. The antipodal meridian of Greenwich is both 180°W and 180°E, the combination of these two components specifies the position of any location on the surface of Earth, without consideration of altitude or depth. The grid formed by lines of latitude and longitude is known as a graticule, the origin/zero point of this system is located in the Gulf of Guinea about 625 km south of Tema, Ghana. To completely specify a location of a feature on, in, or above Earth. Earth is not a sphere, but a shape approximating a biaxial ellipsoid. It is nearly spherical, but has an equatorial bulge making the radius at the equator about 0. 3% larger than the radius measured through the poles, the shorter axis approximately coincides with the axis of rotation

Runway
–
According to the International Civil Aviation Organization, a runway is a defined rectangular area on a land aerodrome prepared for the landing and takeoff of aircraft. Runways may be a surface or a natural surface. Runways are named by a number between 01 and 36, which is generally the magnetic azimuth of the heading in decadegrees. This heading differs from true north by the magnetic declination. A runway numbered 09 points east, runway 18 is south, runway 27 points west, when taking off from or landing on runway 09, a plane would be heading 90°. A runway can normally be used in both directions, and is named for each separately, e. g. runway 33 in one direction is runway 15 when used in the other. The two numbers usually differ by 18, Runway Zero Three Left becomes Runway Two One Right when used in the opposite direction. In some countries, if parallel runways are too close to each other, at large airports with four or more parallel runways some runway identifiers are shifted by 10 degrees to avoid the ambiguity that would result with more than three parallel runways. For example, in Los Angeles, this results in runways 6L, 6R, 7L. At Dallas/Fort Worth International Airport, there are five parallel runways, named 17L, 17C, 17R, 18L, for clarity in radio communications, each digit in the runway name is pronounced individually, runway three six, runway one four, etc. A leading zero, for example in runway zero six or runway zero one left, is included for all ICAO, however, most U. S. civil aviation airports drop the leading zero as required by FAA regulation. This also includes some military airfields such as Cairns Army Airfield and this American anomaly may lead to inconsistencies in conversations between American pilots and controllers in other countries. It is very common in a such as Canada for a controller to clear an incoming American aircraft to, for example, runway 04. In flight simulation programs those of American origin might apply U. S. usage to airports around the world, for example, runway 05 at Halifax will appear on the program as the single digit 5 rather than 05. Runway designations change over time because the magnetic poles slowly drift on the Earths surface, depending on the airport location and how much drift takes place, it may be necessary over time to change the runway designation. As runways are designated with headings rounded to the nearest 10 degrees, for example, if the magnetic heading of a runway is 233 degrees, it would be designated Runway 23. If the magnetic heading changed downwards by 5 degrees to 228, if on the other hand the original magnetic heading was 226, and the heading decreased by only 2 degrees to 224, the runway should become Runway 22. Because the drift itself is slow, runway designation changes are uncommon

Arabic
–
Arabic is a Central Semitic language that was first spoken in Iron Age northwestern Arabia and is now the lingua franca of the Arab world. Arabic is also the language of 1.7 billion Muslims. It is one of six languages of the United Nations. The modern written language is derived from the language of the Quran and it is widely taught in schools and universities, and is used to varying degrees in workplaces, government, and the media. The two formal varieties are grouped together as Literary Arabic, which is the language of 26 states. Modern Standard Arabic largely follows the standards of Quranic Arabic. Much of the new vocabulary is used to denote concepts that have arisen in the post-Quranic era, Arabic has influenced many languages around the globe throughout its history. During the Middle Ages, Literary Arabic was a vehicle of culture in Europe, especially in science, mathematics. As a result, many European languages have borrowed many words from it. Many words of Arabic origin are found in ancient languages like Latin. Balkan languages, including Greek, have acquired a significant number of Arabic words through contact with Ottoman Turkish. Arabic has also borrowed words from languages including Greek and Persian in medieval times. Arabic is a Central Semitic language, closely related to the Northwest Semitic languages, the Ancient South Arabian languages, the Semitic languages changed a great deal between Proto-Semitic and the establishment of the Central Semitic languages, particularly in grammar. Innovations of the Central Semitic languages—all maintained in Arabic—include, The conversion of the suffix-conjugated stative formation into a past tense, the conversion of the prefix-conjugated preterite-tense formation into a present tense. The elimination of other prefix-conjugated mood/aspect forms in favor of new moods formed by endings attached to the prefix-conjugation forms, the development of an internal passive. These features are evidence of descent from a hypothetical ancestor. In the southwest, various Central Semitic languages both belonging to and outside of the Ancient South Arabian family were spoken and it is also believed that the ancestors of the Modern South Arabian languages were also spoken in southern Arabia at this time. To the north, in the oases of northern Hijaz, Dadanitic and Taymanitic held some prestige as inscriptional languages, in Najd and parts of western Arabia, a language known to scholars as Thamudic C is attested
