Tennessee Valley Authority civil engineers monitoring hydraulics of a scale model of Tellico Dam. Civil engineering is a professional engineering discipline that deals with the design, construction, and maintenance of the physical and naturally built environment, including public works such as roads, bridges, canals, dams, airports, sewage systems, pipelines, structural components of buildings ...
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.
A civil engineer is a person who practices civil engineering – the application of planning, designing, constructing, maintaining, and operating infrastructure while protecting the public and environmental health, as well as improving existing infrastructure that may have been neglected.
In telecommunications, a controlled area is an area in which uncontrolled movement will not result in compromise of classified information, that is designed to provide administrative control and safety, or that serves as a buffer for controlling access to limited-access areas.
The International Civil Aviation Organization divides airspace into seven classes, from A to G, in order of decreasing ATC regulation of flights. Classes A to E are controlled airspace. Flight under instrument flight rules (IFR) is allowed in all controlled airspace. Some countries also permit IFR in uncontrolled airspace).
Control areas are established in any areas when the density of air traffic is high: [2] An airway is a case of a "control area or portion of thereof established in the form of a corridor". [3] Terminal Control Area is "a control area normally established at the confluence of ATS routes in the vicinity of one or more major aerodromes." [1] [3] A ...
Control area may refer to: Control area (aviation), a volume of controlled airspace that exists in the vicinity of an airport. Control area, a balancing area within ...
Airspace class is a category used to divide the sky into different zones, defined by both geographical boundaries and altitude levels. The International Civil Aviation Organization (ICAO) provides standardized airspace classifications that most countries follow.
