You need to know the meaning of the term controlled airspace first if you want to know more about controlled airspace. A lot of airspace classification and definition of dimensions are some of the things that controlled airspace refers to in terms of it its definition. Air traffic control service is facilitated by airspace classification that is the main body that deals with the controlled airspace. Some of the things that you can get in controlled airspace include class A, class B, class C and class D and class E. There is a lot of difference that you can get in each of the classes that are in controlled airspace. In class A, it means that the airspace is from the height of eighteen thousand feet mean sea level to the flight level that is included at six hundred feet. Class A airspace includes the underlying airspace that is twelve nautical miles from the cost hence another thing that you need to know about class A controlled airspace. Instrument flight rules are the one that conducts all the operation that takes place in class A controlled air space.
The class of controlled airspace that goes from the surface to a height of ten thousand feet mean sea level is called class B. Class B controlled airspace contain one of the busiest airports when it comes to passenger enplanement and operation. There are some characteristic of class B airspace that you need to know that include individually tailored airspace, two layers, and surface area. The fact that class B airspace is made to have one of the best instrument procedure during the landing of the aircraft makes it be one of the best class. From the air traffic control service, you get to have clearance and separation services to any operation in Class B airspace.
From the surface and above the airport elevation to a height of four thousand feet mean sea level, you get to have class C controlled airspace. Class C airspace include the airport operation control tower, some instrument flight rules, and radar approach controls. Although class C area is tailored, the area contains five nautical miles radius. You need to do one of the most important thing that is a two way communication with the air traffic control service when you want to use a class C airspace.
From the height two thousand and five hundred from the surface of the airport, you can have one of the other class that is class D. You get to have class D airspace tailored individually when the instrument procedures are published. Another thing that you need to know about class D airspace is that it has arrival extension for instrument approach.
