Title: Airport
Context: Generally, this pattern is a circuit consisting of five "legs" that form a rectangle (two legs and the runway form one side, with the remaining legs forming three more sides). Each leg is named (see diagram), and ATC directs pilots on how to join and leave the circuit. Traffic patterns are flown at one specific altitude, usually 800 or 1,000 ft (244 or 305 m) above ground level (AGL). Standard traffic patterns are left-handed, meaning all turns are made to the left. One of the main reason for this is that pilots sit on the left side of the airplane, and a Left-hand patterns improves their visibility of the airport and pattern. Right-handed patterns do exist, usually because of obstacles such as a mountain, or to reduce noise for local residents. The predetermined circuit helps traffic flow smoothly because all pilots know what to expect, and helps reduce the chance of a mid-air collision.

question: Traffic patterns are usually flown at what altitude above ground level? 

answer: 800 or 1,000 ft

question: Are standard traffic patterns right-handed or left-handed? 

answer: left-handed

question: What does AGL stand for? 

answer: above ground level

question: What is one of the main reasons pilots sit on the left side of the airplane? 

answer: Standard traffic patterns are left-handed
Title: Airport
Context: At extremely large airports, a circuit is in place but not usually used. Rather, aircraft (usually only commercial with long routes) request approach clearance while they are still hours away from the airport, often before they even take off from their departure point. Large airports have a frequency called Clearance Delivery which is used by departing aircraft specifically for this purpose. This then allows aircraft to take the most direct approach path to the runway and land without worrying about interference from other aircraft. While this system keeps the airspace free and is simpler for pilots, it requires detailed knowledge of how aircraft are planning to use the airport ahead of time and is therefore only possible with large commercial airliners on pre-scheduled flights. The system has recently become so advanced that controllers can predict whether an aircraft will be delayed on landing before it even takes off; that aircraft can then be delayed on the ground, rather than wasting expensive fuel waiting in the air.

question: At an extremely large airport, what is in place but not usually used? 

answer: a circuit

question: What is the frequency called that is used by departing aircraft for the purpose of requesting approach clearance? 

answer: Clearance Delivery

question: Which aircraft request approach clearance while they are still hours away from the airport? 

answer: commercial with long routes
Title: Airport
Context: There are a number of aids available to pilots, though not all airports are equipped with them. A visual approach slope indicator (VASI) helps pilots fly the approach for landing. Some airports are equipped with a VHF omnidirectional range (VOR) to help pilots find the direction to the airport. VORs are often accompanied by a distance measuring equipment (DME) to determine the distance to the VOR. VORs are also located off airports, where they serve to provide airways for aircraft to navigate upon. In poor weather, pilots will use an instrument landing system (ILS) to find the runway and fly the correct approach, even if they cannot see the ground. The number of instrument approaches based on the use of the Global Positioning System (GPS) is rapidly increasing and may eventually be the primary means for instrument landings.

Title: Airport
Context: On runways, green lights indicate the beginning of the runway for landing, while red lights indicate the end of the runway. Runway edge lighting consists of white lights spaced out on both sides of the runway, indicating the edge. Some airports have more complicated lighting on the runways including lights that run down the centerline of the runway and lights that help indicate the approach (an approach lighting system, or ALS). Low-traffic airports may use pilot controlled lighting to save electricity and staffing costs.

Title: Airport
Context: Hazards to aircraft include debris, nesting birds, and reduced friction levels due to environmental conditions such as ice, snow, or rain. Part of runway maintenance is airfield rubber removal which helps maintain friction levels. The fields must be kept clear of debris using cleaning equipment so that loose material does not become a projectile and enter an engine duct (see foreign object damage). In adverse weather conditions, ice and snow clearing equipment can be used to improve traction on the landing strip. For waiting aircraft, equipment is used to spray special deicing fluids on the wings.

question: What includes debris and nesting birds? 

answer: Hazards to aircraft

question: In adverse weather conditions, what can be used to improve traction on the landing strip? 

answer: ice and snow clearing equipment

answer: airfield rubber removal
Title: Airport
Context: Many ground crew at the airport work at the aircraft. A tow tractor pulls the aircraft to one of the airbridges, The ground power unit is plugged in. It keeps the electricity running in the plane when it stands at the terminal. The engines are not working, therefore they do not generate the electricity, as they do in flight. The passengers disembark using the airbridge. Mobile stairs can give the ground crew more access to the aircraft's cabin. There is a cleaning service to clean the aircraft after the aircraft lands. Flight catering provides the food and drinks on flights. A toilet waste truck removes the human waste from the tank which holds the waste from the toilets in the aircraft. A water truck fills the water tanks of the aircraft. A fuel transfer vehicle transfers aviation fuel from fuel tanks underground, to the aircraft tanks. A tractor and its dollies bring in luggage from the terminal to the aircraft. They also carry luggage to the terminal if the aircraft has landed, and is being unloaded. Hi-loaders lift the heavy luggage containers to the gate of the cargo hold. The ground crew push the luggage containers into the hold. If it has landed, they rise, the ground crew push the luggage container on the hi-loader, which carries it down. The luggage container is then pushed on one of the tractors dollies. The conveyor, which is a conveyor belt on a truck, brings in the awkwardly shaped, or late luggage. The airbridge is used again by the new passengers to embark the aircraft. The tow tractor pushes the aircraft away from the terminal to a taxi area. The aircraft should be off of the airport and in the air in 90 minutes. The airport charges the airline for the time the aircraft spends at the airport.

answer: 90 minutes
Title: Airport
Context: An airbase, sometimes referred to as an air station or airfield, provides basing and support of military aircraft. Some airbases, known as military airports, provide facilities similar to their civilian counterparts. For example, RAF Brize Norton in the UK has a terminal which caters to passengers for the Royal Air Force's scheduled TriStar flights to the Falkland Islands. Some airbases are co-located with civilian airports, sharing the same ATC facilities, runways, taxiways and emergency services, but with separate terminals, parking areas and hangars. Bardufoss Airport , Bardufoss Air Station in Norway and Pune Airport in India are examples of this.

Title: Airport
Context: Airports have played major roles in films and television programs due to their very nature as a transport and international hub, and sometimes because of distinctive architectural features of particular airports. One such example of this is The Terminal, a film about a man who becomes permanently grounded in an airport terminal and must survive only on the food and shelter provided by the airport. They are also one of the major elements in movies such as The V.I.P.s, Airplane!, Airport (1970), Die Hard 2, Soul Plane, Jackie Brown, Get Shorty, Home Alone, Liar Liar, Passenger 57, Final Destination (2000), Unaccompanied Minors, Catch Me If You Can, Rendition and The Langoliers. They have also played important parts in television series like Lost, The Amazing Race, America's Next Top Model, Cycle 10 which have significant parts of their story set within airports. In other programmes and films, airports are merely indicative of journeys, e.g. Good Will Hunting.

Title: Kievan_Rus%27
Context: Kievan Rus' begins with the rule (882–912) of Prince Oleg, who extended his control from Novgorod south along the Dnieper river valley in order to protect trade from Khazar incursions from the east and moved his capital to the more strategic Kiev. Sviatoslav I (died 972) achieved the first major expansion of Kievan Rus' territorial control, fighting a war of conquest against the Khazar Empire. Vladimir the Great (980–1015) introduced Christianity with his own baptism and, by decree, that of all the inhabitants of Kiev and beyond. Kievan Rus' reached its greatest extent under Yaroslav I (1019–1054); his sons assembled and issued its first written legal code, the Rus' Justice, shortly after his death.

Context: Prior to the emergence of Kievan Rus' in the 9th century AD, the lands between the Baltic Sea and Black Sea were primarily populated by eastern Slavic tribes. In the northern region around Novgorod were the Ilmen Slavs and neighboring Krivichi, who occupied territories surrounding the headwaters of the West Dvina, Dnieper, and Volga Rivers. To their north, in the Ladoga and Karelia regions, were the Finnic Chud tribe. In the south, in the area around Kiev, were the Poliane, a group of Slavicized tribes with Iranian origins, the Drevliane to the west of the Dnieper, and the Severiane to the east. To their north and east were the Vyatichi, and to their south was forested land settled by Slav farmers, giving way to steppelands populated by nomadic herdsmen.

Context: Controversy persists over whether the Rus’ were Varangians (Vikings) or Slavs. This uncertainty is due largely to a paucity of contemporary sources. Attempts to address this question instead rely on archaeological evidence, the accounts of foreign observers, legends and literature from centuries later. To some extent the controversy is related to the foundation myths of modern states in the region. According to the "Normanist" view, the Rus' were Scandinavians, while Russian and Ukrainian nationalist historians generally argue that the Rus' were themselves Slavs. Normanist theories focus on the earliest written source for the East Slavs, the Russian Primary Chronicle, although even this account was not produced until the 12th century. Nationalist accounts have suggested that the Rus' were present before the arrival of the Varangians, noting that only a handful of Scandinavian words can be found in modern Russian and that Scandinavian names in the early chronicles were soon replaced by Slavic names. Nevertheless, archaeological evidence from the area suggests that a Scandinavian population was present during the 10th century at the latest. On balance, it seems likely that the Rus' proper were a small minority of Scandinavians who formed an elite ruling class, while the great majority of their subjects were Slavs. Considering the linguistic arguments mounted by nationalist scholars, if the proto-Rus' were Scandinavians, they must have quickly become nativized, adopting Slavic languages and other cultural practices.

question: What controversy currently surrounds the Rus? 

answer: whether the Rus’ were Varangians (Vikings) or Slavs

question: What were the "Rus" accourding to the "Normanist"? 

answer: Scandinavians

question: What did the Russians beleive the Rus were? 

answer: Slavs
Title: Kievan_Rus%27
Context: Ahmad ibn Fadlan, an Arab traveler during the 10th century, provided one of the earliest written descriptions of the Rus': "They are as tall as a date palm, blond and ruddy, so that they do not need to wear a tunic nor a cloak; rather the men among them wear garments that only cover half of his body and leaves one of his hands free." Liutprand of Cremona, who was twice an envoy to the Byzantine court (949 and 968), identifies the "Russi" with the Norse ("the Russi, whom we call Norsemen by another name") but explains the name as a Greek term referring to their physical traits ("A certain people made up of a part of the Norse, whom the Greeks call [...] the Russi on account of their physical features, we designate as Norsemen because of the location of their origin."). Leo the Deacon, a 10th-century Byzantine historian and chronicler, refers to the Rus' as "Scythians" and notes that they tended to adopt Greek rituals and customs.

Title: Kievan_Rus%27
Context: According to the Primary Chronicle, the territories of the East Slavs in the 9th century were divided between the Varangians and the Khazars. The Varangians are first mentioned imposing tribute from Slavic and Finnic tribes in 859. In 862, the Finnic and Slavic tribes in the area of Novgorod rebelled against the Varangians, driving them "back beyond the sea and, refusing them further tribute, set out to govern themselves." The tribes had no laws, however, and soon began to make war with one another, prompting them to invite the Varangians back to rule them and bring peace to the region:

Title: Kievan_Rus%27
Context: The three brothers—Rurik, Sineus, and Truvor—established themselves in Novgorod, Beloozero, and Izborsk, respectively. Two of the brothers died, and Rurik became the sole ruler of the territory and progenitor of the Rurik Dynasty. A short time later, two of Rurik’s men, Askold and Dir, asked him for permission to go to Tsargrad (Constantinople). On their way south, they discovered "a small city on a hill," Kiev, captured it and the surrounding country from the Khazars, populated the region with more Varangians, and "established their dominion over the country of the Polyanians."

question: What were the names of the three brothers that rulled Novgotod, Beloozero, and Izborsk? 

answer: Rurik, Sineus, and Truvor

question: Whoch of the three brothers become the sole ruller over all three of the teritories? 

answer: Rurik

question: What was the name of the small city on the hill that was discovered by Rurik's men? 

answer: Kiev
Title: Kievan_Rus%27
Context: The Chronicle reports that Askold and Dir continued to Constantinople with a navy to attack the city in 863–66, catching the Byzantines by surprise and ravaging the surrounding area, though other accounts date the attack in 860. Patriarch Photius vividly describes the "universal" devastation of the suburbs and nearby islands, and another account further details the destruction and slaughter of the invasion. The Rus' turned back before attacking the city itself, due either to a storm dispersing their boats, the return of the Emperor, or in a later account, due to a miracle after a ceremonial appeal by the Patriarch and the Emperor to the Virgin. The attack was the first encounter between the Rus' and Byzantines and led the Patriarch to send missionaries north to engage and attempt to convert the Rus' and the Slavs.

question: Between what years did Askold and Dir continued to attack Kiev? 

answer: 863–66

question: What did the attack between Rus and Byzantines lead to? 

answer: Patriarch to send missionaries north to engage

question: Wat was the purpose of the Patriarch when they were sent north? 

answer: to convert the Rus' and the Slavs.
Title: Kievan_Rus%27
Context: Rurik led the Rus' until his death in about 879, bequeathing his kingdom to his kinsman, Prince Oleg, as regent for his young son, Igor. In 880-82, Oleg led a military force south along the Dnieper river, capturing Smolensk and Lyubech before reaching Kiev, where he deposed and killed Askold and Dir, proclaimed himself prince, and declared Kiev the "mother of Rus' cities." Oleg set about consolidating his power over the surrounding region and the riverways north to Novgorod, imposing tribute on the East Slav tribes. In 883, he conquered the Drevlians, imposing a fur tribute on them. By 885 he had subjugated the Poliane, Severiane, Vyatichi, and Radimichs, forbidding them to pay further tribute to the Khazars. Oleg continued to develop and expand a network of Rus' forts in Slav lands, begun by Rurik in the north.

Title: Kievan_Rus%27
Context: The new Kievan state prospered due to its abundant supply of furs, beeswax, honey, and slaves for export, and because it controlled three main trade routes of Eastern Europe. In the north, Novgorod served as a commercial link between the Baltic Sea and the Volga trade route to the lands of the Volga Bulgars, the Khazars, and across the Caspian Sea as far as Baghdad, providing access to markets and products from Central Asia and the Middle East. Trade from the Baltic also moved south on a network of rivers and short portages along the Dnieper known as the "route from the Varangians to the Greeks," continuing to the Black Sea and on to Constantinople. Kiev was a central outpost along the Dnieper route and a hub with the east-west overland trade route between the Khazars and the Germanic lands of Central Europe. These commercial connections enriched Rus' merchants and princes, funding military forces and the construction of churches, palaces, fortifications, and further towns. Demand for luxury goods fostered production of expensive jewelry and religious wares, allowing their export, and an advanced credit and money-lending system may have also been in place.

question: Why did the Kievan state prosper? 

answer: abundant supply of furs, beeswax, honey, and slaves for export

question: How many trade routes did the Kievan state control? 

answer: three
