In United States aviation, a National Security Area (NSA) is a designated airspace through which flight is discouraged for reasons of national security. [1]
Flight through NSAs is not prohibited and no special advance clearance or authorization need be obtained to enter them. However, pilots of aircraft are strongly encouraged to either stay clear of NSAs or obtain prior authorization to pass through them in order to reassure the controlling agency that no threat to national security exists.
NSAs are a compromise between normal airspace and restricted or prohibited airspace. NSAs can be temporarily converted into restricted airspace by NOTAMs. [1]
On VFR sectional charts, NSAs are delimited by a heavy dashed magenta border and a special notation.
When not referring to aviation, a National Security Area is a designated area temporarily placed under the command of the National Nuclear Security Administration. It is designed to safeguard classified, sensitive, or restricted information, equipment or materials relevant to the NNSA mission.
The Federal Aviation Regulations (FARs) are rules prescribed by the Federal Aviation Administration (FAA) governing all aviation activities in the United States. The FARs comprise Title 14 of the Code of Federal Regulations (CFR). A wide variety of activities are regulated, such as aircraft design and maintenance, typical airline flights, pilot training activities, hot-air ballooning, lighter-than-air aircraft, man-made structure heights, obstruction lighting and marking, model rocket launches, commercial space operations, model aircraft operations, Unmanned Aircraft Systems (UAS) and kite flying. The rules are designed to promote safe aviation, protecting pilots, flight attendants, passengers and the general public from unnecessary risk.
In aviation, uncontrolled airspace is airspace in which an Air Traffic Control (ATC) service is not deemed necessary or cannot be provided for practical reasons. It is the opposite of controlled airspace. It is that portion of the airspace that has not been designated as Control Area, Control Zone, Terminal Control Area or Transition Area.
Controlled airspace is airspace of defined dimensions within which air traffic control (ATC) services are provided. The level of control varies with different classes of airspace. Controlled airspace usually imposes higher weather minimums than are applicable in uncontrolled airspace. It is the opposite of uncontrolled airspace.
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 outer space which is the expanse or space outside the Earth and aerospace which is the general term for Earth's atmosphere and the outer space within the planet's vicinity. History:
An air defense identification zone (ADIZ) has existed since February 10, 2003, around the Baltimore-Washington Metropolitan Area to restrict air traffic near Washington, D.C.
The Convention on International Civil Aviation, also known as the Chicago Convention, established the International Civil Aviation Organization (ICAO), a specialized agency of the United Nations charged with coordinating international air travel. The Convention establishes rules of airspace, aircraft registration and safety, security, and sustainability, and details the rights of the signatories in relation to air travel. The Convention also contains provisions pertaining to taxation.
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.
Pilot certification in the United States is typically required for an individual to act as a pilot-in-command of an aircraft. It is regulated by the Federal Aviation Administration (FAA), a branch of the U.S. Department of Transportation (USDOT). A pilot may be certified under 14 Code of Federal Regulations (CFR) Part 61 or 14 CFR Part 141. Pilots may also be certified under 14 CFR Part 107 for commercial drone operations.
Canadian airspace is the region of airspace above the surface of the Earth within which Canada has jurisdiction. It falls within a region roughly defined as either the Canadian land mass, the Canadian Arctic or the Canadian archipelago, and areas of the high seas. Airspace is managed by Transport Canada and detailed information regarding exact dimensions and classification is available in the Designated Airspace Handbook which is published every fifty-six days by Nav Canada.
Restricted airspace is an area of airspace typically used by the military in which the local controlling authorities have determined that air traffic must be restricted or prohibited for safety or security concerns. It is one of many types of special use airspace designations and is depicted on aeronautical charts with the letter "R" followed by a serial number.
A military operations area (MOA) is an airspace established outside Class A airspace to separate or segregate certain nonhazardous military activities from IFR Traffic and to identify for VFR traffic where these activities are conducted. Similar structures exist under international flight standards. These are designed for routine training or testing maneuvers. Areas near actual combat or other military emergencies are generally designated as restricted airspace. See Temporary Flight Restriction (TFR).
Special use airspace (SUA) is an area designated for operations of a nature such that limitations may be imposed on aircraft not participating in those operations. Often these operations are of a military nature. The designation of SUAs identifies for other users the areas where such activity occurs, provides for segregation of that activity from other users, and allows charting to keep airspace users informed of potential hazards. Most SUAs are depicted on aeronautical charts and FAA maintains a page showing the current status of most SUAs.
A prohibited airspace is an area (volume) of airspace within which flight of aircraft is not allowed, usually due to security concerns. It is one of many types of special use airspace designations and is depicted on aeronautical charts with the letter "P" followed by a serial number. It differs from restricted airspace in that entry is typically forbidden at all times from all aircraft and is not subject to clearance from ATC or the airspace's controlling body.
The United States airspace system's classification scheme is intended to maximize pilot flexibility within acceptable levels of risk appropriate to the type of operation and traffic density within that class of airspace – in particular to provide separation and active control in areas of dense or high-speed flight operations.
The Air Defense Identification Zone of North America is an air defense identification zone (ADIZ) that covers the airspace surrounding the United States and Canada – in which the ready identification, location, and control of civil aircraft over land or water is required in the interest of national security. This ADIZ is jointly administered by the civilian air traffic control authorities and the militaries of both nations, under the auspices of the North American Aerospace Defense Command (NORAD). The Federal Aviation Administration (FAA) handles the requests of international aircraft and Transport Canada handles Canadian requests. Any aircraft flying in these zones without authorization may be identified as a threat and treated as an enemy aircraft, potentially leading to interception by fighter aircraft.
Flight permits are permits or permission required by an aircraft to overfly, land or make a technical stop in any country's airspace. All countries have their own regulations regarding the issuance of flight permits as there is generally a payment involved. The charges normally payable would be the Route Navigation Facility Charges or RNFC for overflights and also landing and parking charges in case of aircraft making halts. The procedure for issuance of these permits also varies from country to country. More details regarding these can be taken from the respective country's civil aviation authority websites.
The General Civil Aviation Authority (GCAA) is the civil aviation authority of the United Arab Emirates (UAE). Its head office is in Al Rawdah, Abu Dhabi.
The New York metropolitan area has the busiest airport system in the United States and the second busiest in the world after London. It is also the most frequently used port of entry and departure for international flights. In 2011, more than 104 million passengers used the airports under the auspices of the Port Authority of New York and New Jersey (PANYNJ). The number increased to 117 million in 2014.
The 1958 C-130 shootdown incident was the shooting down of an American Lockheed C-130A-II-LM reconnaissance aircraft which had intruded into Soviet airspace during a reconnaissance mission along the Turkish-Armenian border.
The use of unmanned aerial vehicles (UAVs) or drones, is generally regulated by the civil aviation authority of the country. Nevertheless, the International Civil Aviation Organization (ICAO) began exploring the use of drone technology as far back as 2005, which resulted in a 2011 report. France was among the first countries to set a national framework based on this report and larger aviation bodies such as the FAA and the EASA quickly followed suit, which eventually led to influential regulations such as Part 107 and Regulation (EU) 2019/947. As of January 2022, several countries are working on new regulations, ranging from BVLOS operations to UTM activities, which include the US, the EU, India, South Korea, Japan, and Australia among others.
