Many class B airspaces diverge from this model to accommodate traffic patterns or local topological or other features. The upper limit of class B airspace is normally 10,000 feet (3,000 m) MSL. [5] All aircraft entering class B airspace must obtain ATC clearance prior to entry and must be prepared for denial of clearance.
Class B is a class of airspace in the United States which follows International Civil Aviation Organization (ICAO) airspace designation. Class B airspace areas are designed to improve aviation safety by reducing the risk of midair collisions in the airspace surrounding airports with high-density air traffic operations. [1]
SVFR flight in Class A airspace is prohibited. Class B airspace is used to control the flow of traffic around major airports. The airspace is charted on a VFR sectional chart with a series of blue lines. Within these blue lines, the floor and the ceiling of the Class B airspace is defined.
The configuration of each Class B airspace area is individually tailored, consists of a surface area and two or more layers (some Class B airspace areas resemble upside-down wedding cakes), and is designed to contain all published instrument procedures once an aircraft enters the airspace.
Class B airspace extends from the surface up to 10,000 ft. AGL and is the area above and around the busiest airports (e.g., LAX, MIA, CVG) and is also heavily controlled. A side view of Class B airspace resembles an upside-down wedding cake with three layers becoming bigger toward the top.
The bright laser beams, which flash red-red-green, are easily seen, even during daylight. The laser beams can be seen 15 to 20 miles (24 to 32 km) away. Other pilots are unlikely to see the lasers because, when activated, the directional beams are pointed at the aircraft that has crossed into restricted airspace. Multiple lasers could be activated.
This initial rule did not include small, general-aviation aircraft. Therefore, on May 15, 1980, the Federal Aviation Administration, implemented what is called Class B airspace to provide for the separation of all aircraft operating in the area. Additionally, all aircraft, regardless of size, are required to operate under "positive radar ...
The class B airspace used by the three airports is extremely congested. The Federal Aviation Administration (FAA) limits the number of flights per hour but they rank among the top five airports in the United States for delays. [6] [7]
