Class B Clearance Required?


Subscriber question:

"If I'm receiving VFR advisories, do I need to make a separate ATC request for clearance through Class B airspace if it is along my route of flight?"
- Carl P.


“A specific ATC clearance is required for all aircraft to operate in Class B airspace. Even if you are in communication with the controlling ATC facility and receiving traffic advisories, you must request and receive the clearance. It is up to the pilot in command to monitor their position and not enter the Class B either laterally or vertically.

If you are talking to ATC and approaching the boundary, you must request the clearance. Say it simply and directly.

Boston Approach, Cessna Three Two Alpha is requesting Class Bravo clearance at 3,500 direct Bedford.

Remember that the cloud clearance requirements for VFR operations in a Bravo is clear of clouds. If an ATC assigned altitude or route will put you in the clouds, you must advise ATC and request a change in route or altitude.”

In your area of the country, how do controllers generally react when you are VFR and request clearance through Class B airspace?

(NEW) VFR Mastery scenario #72 “Rocky Mountain Milestone” is now available. You know high-altitude flying, as it’s where you trained. You have a capable airplane and a clear plan in mind. The devil is in the details when it comes to calculated performance, though, and a few extra degrees can make all the difference in getting off the pavement. Watch the Intro video.
