You will be under radar contact and treated almost like an ifr f. Start studying airspace and vfr rules.

Upside down wedding cake airspace. Class b airspace surrounds large busy airports. For example in st. Airspace over land and water where id location and control of aircraft are required for national.
Its shape is generally an upside down wedding cake but it can vary quite a bit. Learn vocabulary terms and more with flashcards games and other study tools. Each outer shelf encompasses a larger swath of land but does not reach down to the surface.
It looks a lot like a 3 tiered upside down wedding cake overtop of the airport see below. The airspace is commonly depicted as resembling an upside down wedding cake. The main idea is that there are layers that get progressively wider and have a higher floor than inner layers.
We often refer to the design and shape of class b airspace as an upside down wedding cake. The innermost ring extends from the surface area around the airport to typically 10000 msl. Louis pictured below the inner ring extends from the continue reading class b airspace.
Several outer rings usually surround it with progressively higher floors to allow traffic into nearby airports without entering the primary airports class b airspace. Its like an upside down wedding cake that tops out at 2400 msl. The smallest section of the cake is typically a 5 mile radius containing the main portion of the airspace from the surface to 10000 ft msl plus two outer shelves.
That airspace requires a specific clearance not unlike an ifr clearance. Class b airspace is the airspace above a major airport. I have long believed that in terms of airport advocacy we need to subscribe to a three tiered model.
We understand that the first level extends from the ground upward. It has been described as an upside down wedding cake. A larger ring sits on top of that and a still larger ring above that.
The reason is the way class b airspace is designed is in layers that progressively get wider the higher up from the surface you go. Upside down wedding cake shape surface to approx 10000 msl radius for top layer is typically 20 nm each layer marked with fractions with top and base in hundreds of feet msl atc always needs to see you and know your alt must be cleared to enter class b airspace contact is not enough many types have published vfr routes. While the class b airspace around atlanta is very complicated you can see that it is a big funnel shaped area that all tops out at 12500 feet the 125 in hundreds of feet.
As pilots we are all used to looking at class b airspace as an upside down wedding cake. 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.
