Flying Under Class B Airspace

Source:, Featuring John Krug

Subscriber question:

"If I fly under Class Bravo airspace (i.e. an outer ring where the floor is 3,000 feet), do I need a clearance into Bravo? What if I am receiving Flight Following?" - Arthur C.

class B airspace


"No, a clearance is only required if you will enter the Bravo airspace at a charted altitude.

Let's review Class Bravo airspace and requirements. A Bravo is generally that airspace from the surface to 10,000 feet MSL surrounding the nation's busiest airports. The configuration of each Bravo is individually tailored and consists of a surface area and two or more layers (some Class Bravos resemble upside down wedding cakes), and is designed to contain all published instrument procedures once an aircraft enters the airspace. An ATC clearance is required for all aircraft that receive separation services within the airspace.

Even though you may be operating below the Bravo, you should use caution against operating too closely to the boundaries, especially where the floor of the Class B airspace is 3,000 feet or less above the surface. Another caution area is where VFR cruise altitudes are at or near the floor of higher levels.

You should also use the VFR Planning Chart as a tool for planning flight in proximity to Class B airspace. Charted VFR Flyways are published on the back of the existing VFR Terminal Area Charts."
