Airspace Control Brigade
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, 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 ...

Country
A country is a distinct part of the world, such as a state, nation, or other political entity. It may be a sovereign state or make up one part of a larger state. For example, the country of Japan is an independent, sovereign state, while the country of Wales is a component of a multi-part sovereign state, the United Kingdom. A country may be a historically sovereign area (such as Korea), a currently sovereign territory with a unified government (such as Senegal), or a non-sovereign geographic region associated with certain distinct political, ethnic, or cultural characteristics (such as the Basque Country). The definition and usage of the word "country" is flexible and has changed over time. ''The Economist'' wrote in 2010 that "any attempt to find a clear definition of a country soon runs into a thicket of exceptions and anomalies." Most sovereign states, but not all countries, are members of the United Nations. The largest country by area is Russia, while the smallest is ...

Air Rights
Air rights are the property interest in the "space" above the earth's surface. Generally speaking, owning, or renting, land or a building includes the right to use and build in the space above the land without interference by others. This legal concept is encoded in the Latin phrase ''Cuius est solum, eius est usque ad coelum et ad inferos'' ("''Whoever owns the soil, it is theirs up to Heaven and down to Hell''."), which appears in medieval Roman law and is credited to 13th-century glossator Accursius; it was notably popularized in common law in '' Commentaries on the Laws of England'' (1766) by William Blackstone; see origins of phrase for details. Air travel Property rights defined by points on the ground once extended indefinitely upward. This notion remained unchallenged before air travel became popular in the early 20th century. To promote air transport, legislators established a public easement for transit at high altitudes, regardless of real estate ownership. New ...

Flyover Rights
The freedoms of the air are a set of commercial aviation rights granting a country's airlines the privilege to enter and land in another country's airspace. They were formulated as a result of disagreements over the extent of aviation liberalisation in the Convention on International Civil Aviation of 1944, known as the Chicago Convention. The United States had called for a standardized set of separate air rights to be negotiated between states, but most other countries were concerned that the size of the U.S. airlines would dominate air travel if there were not strict rules. The freedoms of the air are the fundamental building blocks of the international commercial aviation route network. The use of the terms "freedom" and "right" confers entitlement to operate international air services only within the scope of the multilateral and bilateral treaties ( air services agreements) that allow them. The first two freedoms concern the passage of commercial aircraft through foreign ...

Airspace Class
The world's navigable airspace is divided into three-dimensional segments, each of which is assigned to a specific class. Most nations adhere to the classification specified by the International Civil Aviation Organization (ICAO) and described below, though they might use only some of the classes defined below, and significantly alter the exact rules and requirements. Similarly, individual nations may also designate special use airspace (SUA) with further rules for reasons of national security or safety. Abbreviations used in this article ICAO definitions On March 12, 1990, ICAO adopted the current airspace classification scheme. The classes are fundamentally defined in terms of flight rules and interactions between aircraft and air traffic control (ATC). Generally speaking, the ICAO airspaces allocate the responsibility for avoiding other aircraft, namely either to ATC (if separation is provided) or to the aircraft commander (if not). Some key concepts are: * Separation: Mai ...

Air Sovereignty
Air sovereignty is the fundamental right of a sovereign state to regulate the use of its airspace and enforce its own aviation law – ''in extremis'' by the use of fighter aircraft. The upper limit of national airspace is not defined by international law. NATO air policing As part of the principle of collective defence in peacetime NATO members carry out air policing missions to protect the integrity of Allied airspace. As part of the mission aircraft are used in a Quick Reaction Air role to respond to both civilian and military aircraft in distress and any aircraft that approach allied airspace and fail to identify themselves, fail to communicate with Air Traffic Control or fail to file a flight plan. A number of NATO countries cannot sustain a force of quick reaction aircraft, so aircraft of other member states provide cover, such as in the Baltic Air Policing, Baltic Area and Icelandic Air Policing, Icelandic Area.In the Benelux area (Belgium, Luxembourg and the Netherlands) ...

Parachuting
Parachuting, including also skydiving, is a method of transiting from a high point in the atmosphere to the surface of Earth with the aid of gravity, involving the control of speed during the descent using a parachute or parachutes. For human skydiving, it may involve a phase of more or less free-falling (the skydiving segment) which is a period when the parachute has not yet been deployed and the body gradually accelerates to terminal velocity. For cargo parachuting, the parachute descent may begin immediately, such as a parachute-airdrop in the lower atmosphere of Earth, or be significantly delayed, such as in a planetary atmosphere where an object is descending "under parachute" following atmospheric entry from space, and may begin only after the hypersonic entry phase and initial deceleration that occurs due to friction with the thin upper atmosphere. History Common uses Parachuting is performed as a recreational activity and a competitive sport, and is widel ...

NOTAM
A Notice to Airmen/Notice to Air Missions (NOTAM), is a notice filed with an aviation authority to alert aircraft pilots of potential hazards along a flight route or at a location that could affect the flight. NOTAMs are unclassified notices or advisories distributed by means of telecommunication that contain information concerning the establishment, conditions or change in any aeronautical facility, service, procedure or hazard, the timely knowledge of which is essential to personnel and systems concerned with flight operations. NOTAMs are created and transmitted by government agencies and airport operators under guidelines specified by Annex 15: Aeronautical Information Services of the Convention on International Civil Aviation (CICA). The acronym ''NOTAM'' came into common use following the ratification of the CICA, which came into effect on 4 April 1947. Notices to airmen were normally published in a regular publication by each country's air authorities (e.g., in ''Flight Inte ...

White House
The White House is the official residence and workplace of the president of the United States. It is located at 1600 Pennsylvania Avenue NW in Washington, D.C., and has been the residence of every U.S. president since John Adams in 1800. The term "White House" is often used as a metonym for the president and his advisers. The residence was designed by Irish-born architect James Hoban in the neoclassical style. Hoban modelled the building on Leinster House in Dublin, a building which today houses the Oireachtas, the Irish legislature. Construction took place between 1792 and 1800, using Aquia Creek sandstone painted white. When Thomas Jefferson moved into the house in 1801, he (with architect Benjamin Henry Latrobe) added low colonnades on each wing that concealed stables and storage. In 1814, during the War of 1812, the mansion was set ablaze by British forces in the Burning of Washington, destroying the interior and charring much of the exterior. Reconstruction began ...
