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 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.
Controlled airspace is a generic term that covers the different classifications of airspace and defined dimensions within which air traffic control (ATC) service is provided in accordance with the airspace classification. Controlled airspace consists of: [14] Class A; Class B; Class C; Class D; Class E; Airspace classes in the United States
A side view of Class B airspace resembles an upside-down wedding cake with three layers becoming bigger toward the top. Class B's layers are designed individually to meet the needs of the airport they overlay. Pilots must also receive clearance to enter the Class B airspace but Visual Flight Rules may be used, unlike in Class A airspace. Class ...
White space around the chart is filled with map information and the legend, scales, and tables of airport and airspace information. Terrain is color-coded for its elevation and major roads, cities, and bodies of water are shown for visual reference, as well as other identifiable structures (e.g., stadiums and water towers ).
The chart also shows information on airspace classes, ground-based navigation aids, radio frequencies, longitude and latitude, navigation waypoints, navigation routes. Sectional charts are in 1:500,000 scale and are named for a city on the map.
Drone activity caused officials to close airspace over one of the United States’ most critical Air Force bases for almost four hours late Friday and early Saturday, according to a base ...
The airspace is commonly depicted as resembling an "upside-down wedding cake". The innermost ring extends from the surface area around the airport to typically 10,000' MSL . Several outer rings usually surround it with progressively higher floors to allow traffic into nearby airports without entering the primary airport's Class B airspace.
