Class C airspace is typically less busy than Class B airspace and is indicated on a sectional by a solid magenta line. 3. The dimensions of Class B airspace vary depending on the needs of the airport. Class B airspace is controlled airspace that is established to separate the flow of all airport arrivals and departures; this is why Class B airspace is usually found at major airports around the world. If you are flying a PlaneView aircraft (G350, G450, G550, G650) and want to see a nifty trick to keep an eye out for the Class B demons, read below, PlaneView Trick. The upper most level of Class B airspace may extend horizontally with radius of up to a 15 nautical miles around the airport tower. Class B airspace, surrounds the nation’s busiest airports and usually goes as high as 10,000 feetMSL, in some cases even higher. The upper limit of class B airspace is normally 10,000 feet (3,000 m) MSL. All low level controlled airspace above 12 500 feet ASL or at and above the MEA, whichever is higher, up to but not including 18 000 feet ASL will be Class B airspace. Class E airspace starts at various altitudes, but always exists above 14,500 feet. The Class D airspace areas listed below consist of specified airspace within which all aircraftoperators are subject to operating rules and equipment requirements of Part 91 of the Federal Aviation Regulations (see 14 CFR 91.129). Like Class B airspace, Class C airspace also has an upper shelf (think upside down wedding cake again. Class C airspace is more restrictive than Class D, Class E, or Class G airspace; 4. Class E airspace. Description: (NATO) An area in which there are special restrictive measures employed to prevent or minimize interference between friendly forces. Class D. Class D airspace … In Class B airspace itself, you can’t fly faster than250 knots, unless otherwise cleared by ATC. All aircraft entering class B airspace must obtain ATC clearance prior to entry and must be prepared for denial of clearance. Generally, that airspace from the surface to 4,000 feet above the airport elevation (charted in MSL) surrounding those airports that have an operational control tower, are serviced by a radar approach control, and that have a certain number of IFR operations or passenger enplanements. 2. 3-2-4. A generic term that covers the different classification of airspace (Class A, Class B, Class C, Class D, and Class E airspace) and defined dimensions within which air traffic control service is provided to IFR flights and to VFR flights in accordance with the airspace classification. Class B Airspace: Class B airspace surrounds the nation's busiest airports and usually goes as high as 10,000 feet MSL, in some cases even higher. General.
