Airspace Class B Bravo Airspace
The airspace surrounding the busiest airports, in terms of aircraft operation is classified as class B airspace.
Some examples of class B airspace, KJFK New York, Miami International KMIA, Dallas Forth Worth KDFW, Los Angeles KLAX.

It is from the surface to 10 000 feet MSL, in different layers.
One way of describing the different layers is like an upside down wedding cake.
The closer you get to the primary airport inside class B airspace, the higher the surrounding layer is.

For a pilot to take off from an airport inside class B airspace, he or she needs to be at least a private pilot. Or a student pilot with an endorsement from a certified flight instructor, that he/she have received adequate training both theoretical and practical in that specific class B airspace.
In some class B airspace, for example Dallas Forth Worth, the student pilot endorsement is not enough; you have to be a private pilot to fly there.
The minimum equipment for operation inside class B airspace is
An operable two-way radio, a Mode C Transponder with altitude encoding.
And if you are flying IFR you need to have VOR (radio navigation) equipment to.
Before you enter class B airspace you need to obtain an ATC clearance from the ATC facility in the specific class B airspace, prior to enter.
If you are flying VFR (visual flight rules), you need to make sure you meet the required weather minimums.
In class B airspace this means that you are clear of clouds, with at least 3 statute miles visibility.
On navigational charts, class B is depicted with a solid blue line. The base and ceiling of the airspace is shown with one number over the other for example 100/20.
Unless authorized by ATC, the maximum speed under 10 000 feet and in class B airspace is 250 Knots.
