SCAT-I
SCAT-I ''(Special CATegory I)'' is an instrument landing system for aircraft, based on Differential GPS. It is developed under project management by Avinor, the Norwegian airport administration. It is installed on several short runway airports for domestic operation in Norway. It requires special equipment to be installed in the aircraft, and allows precision landings in bad visibility, something that is important on short runways where bad weather including snow storms are common. The system was operational for the first time in 2007, first installed at Brønnøysund Brønnøysund () is a town and the administrative centre of Brønnøy Municipality in Nordland county, Norway. It is also a former municipality within Nordland county. The village of Brønnøysund originally was declared a ladested in 1923 wh ..., then at several other airports. As of 2013 it is installed at 21 regional airports in Norway. [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Instrument Landing
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 ...

Differential GPS
Differential Global Positioning Systems (DGPSs) supplement and enhance the positional data available from global navigation satellite systems (GNSSs). A DGPS for GPS can increase accuracy by about a thousandfold, from approximately to . DGPSs consist of networks of fixed position, ground-based reference stations. Each reference station calculates the difference between its highly accurate known position and its less accurate satellite-derived position. The stations broadcast this data locally—typically using ground-based transmitters of shorter range. Non-fixed (mobile) receivers use it to correct their position by the same amount, thereby improving their accuracy. The United States Coast Guard (USCG) and the Canadian Coast Guard (CCG) each run DGPSs in the United States and Canada on longwave radio frequencies between and near major waterways and harbors. The USCG's DGPS was named NDGPS (Nationwide DGPS) and was jointly administered by the Coast Guard and the U.S. Departmen ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Avinor
Avinor AS is a state-owned limited company that operates most of the civil airports in Norway. The Norwegian state, via the Norwegian Ministry of Transport and Communications, controls 100 percent of the share capital. Avinor was created on 1 January 2003, by the privatization of the Norwegian Civil Aviation Administration known as ''Luftfartsverket''. Its head office is in Bjørvika, Oslo, located on the seaside of Oslo Central Station. Avinor owns and operates 44 airports in Norway, fourteen in association with the Royal Norwegian Air Force, and is responsible for air traffic control services in Norway. In addition to the 44 airports, it operates three Area Control Centers: Bodø Air Traffic Control Center, Stavanger Air Traffic Control Center and Oslo ATCC. , the chief executive officer was Sverre Quale who has been in the job since 18 April 2006. He was previously the head of the Norwegian Accident Investigation Board. As of 2011, Sverre Quale has been employed as the C ...

STOLport
A STOLport or STOLPORT was an airport designed with STOL (Short Take-Off and Landing) operations in mind, usually for an aircraft class of certain weight and size. The term "STOLport" did not appear to be in common usage as of 2008, although was commonly used by pilots flying into Biggin Hill during 1986/87 when the London City Airport London City Airport is a regional airport in London, England. It is located in the Royal Docks in the Borough of Newham, approximately east of the City of London and east of Canary Wharf. These are the twin centres of London's financial ... was opened restricting approaches and ceilings to the north of Biggin. A STOLport normally had a short single runway, in general shorter than . STOLports only accepted certain types of aircraft, often only smaller propeller aircraft, and often with limits on the amount of fuel that can be taken. In the United States, short runway facilities are simply known as airports, and the term "STOLport" has not ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Brønnøysund Airport, Brønnøy
Brønnøysund () is a town and the administrative centre of Brønnøy Municipality in Nordland county, Norway. It is also a former municipality within Nordland county. The village of Brønnøysund originally was declared a ladested in 1923 which made it an independent municipality. After merging with Brønnøy in 1964, it lost its town status. Then in 2000, it once again received town status. The town lies along the coast and is often called "the coastal town in the middle of Norway." Brønnøysund is also the regional center of Southern Helgeland. The town has a population (2018) of 5,045 and a population density of . History During the Viking era, ''Torgar'', by the foot of the legendary mountain Torghatten, was a nationally powerful chieftain seat and an important commercial center along the coast. The original inhabitants were wiped out in an outright massacre by ''Duke Skule'' and his men in the Norwegian civil wars that raged around 1240, in the high medieval e ...

Aircraft Landing Systems
An aircraft is a vehicle that is able to fly by gaining support from the air. It counters the force of gravity by using either static lift or by using the dynamic lift of an airfoil, or in a few cases the downward thrust from jet engines. Common examples of aircraft include airplanes, helicopters, airships (including blimps), gliders, paramotors, and hot air balloons. The human activity that surrounds aircraft is called ''aviation''. The science of aviation, including designing and building aircraft, is called ''aeronautics.'' Crewed aircraft are flown by an onboard pilot, but unmanned aerial vehicles may be remotely controlled or self-controlled by onboard computers. Aircraft may be classified by different criteria, such as lift type, aircraft propulsion, usage and others. History Flying model craft and stories of manned flight go back many centuries; however, the first manned ascent — and safe descent — in modern times took place by larger hot-air b ...
