Airspace is actually classified into several classes, and one of these is Class B. The B tag here is very accurate, and is meant to stand for “big.” That is a fact, because Class B is indeed the biggest airspace there is for any pilot to navigate. Even if it is big, it is actually very crowded as majority of the world’s traffic fly through Class B airspace. Thus, for a pilot, it is important to understand Class B airspace as it can help him navigate this sector of aerial territory effectively and safely since both large and small aircraft are found in Class B.
Now, Class B is a strictly regulated airspace due to the amount of traffic that goes back and forth in it. This means that pilots need to meet certain requirements before they can enter into class B airspace this make the area safe for you and the other pilots operating in it. You don’t want to accidentally bump into the flight path of a big Boeing 747, do you?
One of the requirements in order to qualify flying into Class B is: flight clearance! With the congested nature of such an airspace, a pilot needs to receive flight clearance from the controller first. Getting flight clearance means hearinf the magic words "cleared into class bravo airspace".
Second, your aircraft must have the necessary equipment for flying into Class B airspace. One that we've already touched on is a two-way radio to enable smooth communication with the controller: you need to maintain constant communication with the controller in order to receive timely notifications. These notifications will be necessary to avoid other aircraft along with other safety alerts. Second, pilots flying into class B airspace must have a Mode C Transponder. The Mode C transponder allows the controller to keep track of your altitude.
Flying in Class B can be stressful but when you meet the requirements and are operating within your personal minimums. Navigating the airspace will be a breeze.
