Air Traffic Control Issued Advisory / Alert
Airspace Structure; Procedure
While descending via the SERFR2 Star and approaching EDDYY intersection I was notified that I will be below class B airspace for the next 1/2 mile. The current speed constraint was 240 kts which meant I was above the 200 kt limit below Class B airspace. It happened because the STAR published altitude constraints didn't respect the Class B floor. Have the Class B vertical limits printed on the STAR chart if the STAR altitude constraints are below the floor.
[Report narrative contained no additional information.]
A321 flight crew reported being advised by ATC that the SERFR2 arrival would take them below Class B airspace. The design of this arrival caused them to momentarily exceed the speed requirement below Class B airspace.
