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. The main body that deals with controlled airspace is air traffic control service that is facilitated by airspace classification. There are a lot of things that you can get in controlled airspace that 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. When you include the flight level that is at the height of six hundred feet to a height of eighteen thousand feet mean sea level, you get to have one of the classes that are class A. From the cost twelve nautical miles, you get to have the underlying airspace that is included in class A controlled airspace that you need to know. All the activities that take part in class A controlled airspace it is conducted by instrument flight.
In class B controlled airspace, you get to have airspace from the surface up to ten thousand feet mean sea level. When it comes to passenger enplanement and operation, you get to have one of the busiest airports in Class B airspace. There are some characteristic of class B airspace that you need to know that include individually tailored airspace, two layers, and surface area. One of the main thing that makes class B airspace to be one of the best is the fact that it has one of the best instrument procedure during the landing of aircraft. You need to have clearance and separation services from the air traffic control service to have any operation in Class B airspace.
Class C controlled airspace is the one that is found from the height of four thousand feet mean sea level from the surface and above the elevation. Class C airspace include the airport operation control tower, some instrument flight rules, and radar approach controls. The area of class C airspace contain five nautical miles radius although it is tailored. A two way radio communication with the air traffic control service is one of the things that you need to do when you want to use the area under class C airspace.
From the surface to two thousand five hundred feet mean sea level, you get to have a class D airspace. When the instrument procedures are published, you get to have a class D airspace tailored individually. There is extension for instrument approach in class D airspace hence another thing that you need to know about it.
