How do Class B airspace entry requirements differ from Class G airspace?

Entering Class B is restricted and tightly controlled because it surrounds busy airports; you must obtain ATC clearance before you enter and you must maintain two-way radio communications with ATC. In practice, you’ll be given a discrete transponder code and you must follow ATC instructions as you move through the airspace. This strict control helps manage the high volume of traffic and reduces risk of conflicts. By contrast, Class G is uncontrolled airspace, so there’s no requirement to obtain ATC clearance to operate there. You fly under the general rules applicable to VFR or IFR, and you’re responsible for your own separation from terrain and other aircraft within the limits of those rules. You still need to comply with weather minimums and other basic operating rules, but there’s no active ATC authorization needed to enter or fly there.
