Bröhn
The Bröhn (405 m), is the highest hill in the Deister range in the German state of Lower Saxony. It owes its name to the broom growing here (, but formerly known as ' or '). The highest point of the hill is close to the , an observation tower on the territory of the town of Springe close to the boundary of the municipality of Wennigsen. Height At 405.0 metres above sea level (NN), the Bröhn is: * the highest hill in the Deister, * the highest hill on the extreme northern rim of the German Central Uplands, because all hills in Germany with a higher latitude are lower than the Bröhn. Observation tower On the summit of the Bröhn stands the Anna Tower (''Annaturm''), a microwave tower made of reinforced concrete, the 5th successor to the original survey tower that was built on this spot at the instigation of Professor Carl Friedrich Gauss in 1834. From this observation tower there is a panoramic view in good weather over the Calenberg Land as far as Hildesheim and Hanove ...

Hills Of Lower Saxony
This List of mountains and hills in Lower Saxony shows a selection of high or well-known mountains and hills in the German state of Lower Saxony (''in order of height''). Although there is no universally agreed definition of a 'mountain', summits at 2.000 feet (610 metres) or higher may generally be referred to as mountains; those below 2.000 feet as 'hills',Whittow, John (1984). ''Dictionary of Physical Geography''. London: Penguin, 1984. . hence the division of this list. By this definition, it can be seen that all the mountains in Lower Saxony occur in the Harz. Highest points in Lower Saxony's regions The following table lists the highest points in the various landscapes (hill ranges or regions) of Lower Saxony. In the "Landscape" column, major hill ranges are shown in bold. Clicking "List" in the rows of the "List" column links to other hills or mountains in that landscape – some of which are outside Lower Saxony.

Deister
The Deister is a chain of hills in the German state of Lower Saxony, about 15 mi (25 km) southwest of the city of Hanover. It runs in a north-westerly direction from Springe in the south to Rodenberg in the north. The next in the chain of hills to the south is the Kleiner Deister ("Little Deister") from which it is separated by the flat pass of the Deister Gate. It is surrounded by Springe, Wennigsen, Barsinghausen, Bad Nenndorf, Rodenberg and Bad Münder (counter-clockwise, starting in the south). It has a total length of 21 km (14 mi), and rises in the Hofeler to a height of 395 m (1,250 ft). The highest point is the Bröhn at 405 m (1,312 ft). The chain is well-wooded and abounds in game. From the 17th century on there were several coal mines; the last were abandoned in the 1950s.

History The founding date of Wennigsen is unknown. It possibly dates back to 5th to 8th century.

Republic F-84 Thunderjet
The Republic F-84 Thunderjet was an American turbojet fighter-bomber aircraft. Originating as a 1944 United States Army Air Forces (USAAF) proposal for a "day fighter", the F-84 first flew in 1946. Although it entered service in 1947, the Thunderjet was plagued by so many structural and engine problems that a 1948 U.S. Air Force review declared it unable to execute any aspect of its intended mission and considered canceling the program. The aircraft was not considered fully operational until the 1949 F-84D model and the design matured only with the definitive F-84G introduced in 1951. In 1954, the straight-wing Thunderjet was joined by the swept-wing F-84F Thunderstreak fighter and RF-84F Thunderflash photo reconnaissance aircraft. The Thunderjet became the USAF's primary strike aircraft during the Korean War, flying 86,408 sorties and destroying 60% of all ground targets in the war as well as eight Soviet-built MiG fighters. Over half of the 7,524 F-84s produced served with ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Air Traffic Control
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 infor ...

Nautical Mile
A nautical mile is a unit of length used in air, marine, and space navigation, and for the definition of territorial waters. Historically, it was defined as the meridian arc length corresponding to one minute ( of a degree) of latitude. Today the international nautical mile is defined as exactly . The derived unit of speed is the knot, one nautical mile per hour. Unit symbol There is no single internationally agreed symbol, with several symbols in use. * M is used as the abbreviation for the nautical mile by the International Hydrographic Organization. * NM is used by the International Civil Aviation Organization. * nmi is used by the Institute of Electrical and Electronics Engineers and the United States Government Publishing Office. * nm is a non-standard abbreviation used in many maritime applications and texts, including U.S. Government Coast Pilots and Sailing Directions.

Radius
In classical geometry, a radius ( : radii) of a circle or sphere is any of the line segments from its center to its perimeter, and in more modern usage, it is also their length. The name comes from the latin ''radius'', meaning ray but also the spoke of a chariot wheel. as a function of axial position ../nowiki>" Spherical coordinates In a spherical coordinate system, the radius describes the distance of a point from a fixed origin. Its position if further defined by the polar angle measured between the radial direction and a fixed zenith direction, and the azimuth angle, the angle between the orthogonal projection of the radial direction on a reference plane that passes through the origin and is orthogonal to the zenith, and a fixed reference direction in that plane.
