Class Bravo Clearance at Assigned Altitude

Asked by: 1927 views Airspace

When "cleared through Class B at [an assigned altitude]", and that assigned altitude is higher or lower than my current altitude, am I required to climb / descend to that assigned altitude before ENTERING any portion of the Class B airspace? Or is permission implied to enter Class B while climbing or descending to that altitude?

    If class B approach tells you, “Cleared to enter class B airspace, climb [or descend] and maintain [altitude],” you should read back the clearance and say, “leaving [current altitude] for [new altitude].” If you’re far enough out you should reach your new altitude before entering class B airspace, but if you’re too close to the boundary to get there, ATC will understand that you’re climbing or descending to get there. However, they expect you to climb or descend at a rate of at least 500 feet per minute. Now, if they specifically tell you to not enter class B airspace before you’re at the assigned altitude, make sure you comply.

    I tried to find a reference to link you to for information on this but I couldn’t find anything that directly addressed the specific scenario of your question.
