Air Traffic Incident | Pilot Deviation |
Narrative:
We were cleared for visual runway 12L msp. Approximately 14 NM from touchdown, we began descent to land visually runway 12L msp. Upon reaching 3700 ft, ATC advised us that we had descended below class B airspace. We should have maintained at or above GS and that traffic was below us. We immediately climbed to 4000 ft unaware of precisely where the floor of the class B airspace was. I feel that ATC should have given us a minimum altitude to maintain until a DME from msp was reached to descend to the runway. The responsibility to know where class B airspace is puts a burden on the pilot that in the final phase of flight is unacceptable to my operation. Until I find out whether or not it is the pilot's responsibility to know where the floor of class B airspace is, I will not accept visual approachs to any class B airports.

Title: A320 FLC EXITS CLASS B AIRSPACE WHILE ON VISUAL APCH TO MSP.
Narrative: WE WERE CLRED FOR VISUAL RWY 12L MSP. APPROX 14 NM FROM TOUCHDOWN, WE BEGAN DSCNT TO LAND VISUALLY RWY 12L MSP. UPON REACHING 3700 FT, ATC ADVISED US THAT WE HAD DSNDED BELOW CLASS B AIRSPACE. WE SHOULD HAVE MAINTAINED AT OR ABOVE GS AND THAT TFC WAS BELOW US. WE IMMEDIATELY CLBED TO 4000 FT UNAWARE OF PRECISELY WHERE THE FLOOR OF THE CLASS B AIRSPACE WAS. I FEEL THAT ATC SHOULD HAVE GIVEN US A MINIMUM ALT TO MAINTAIN UNTIL A DME FROM MSP WAS REACHED TO DSND TO THE RWY. THE RESPONSIBILITY TO KNOW WHERE CLASS B AIRSPACE IS PUTS A BURDEN ON THE PLT THAT IN THE FINAL PHASE OF FLT IS UNACCEPTABLE TO MY OP. UNTIL I FIND OUT WHETHER OR NOT IT IS THE PLT'S RESPONSIBILITY TO KNOW WHERE THE FLOOR OF CLASS B AIRSPACE IS, I WILL NOT ACCEPT VISUAL APCHS TO ANY CLASS B ARPTS.
