GV FLT CREW EXCEEDS 200 KTS BELOW THE FLOOR OF THE SFO CLASS B AIRSPACE WHILE FLYING THE LOUPE DEP FROM SJC.

Narrative

WE DEPARTED FROM RWY 30L ON THE LOUPE 1 DEP FRO SJC. THIS HAS YOU ON THE RWY HDG UNTIL 1.8 DME FROM SJC THEN A R CLBING TURN TO HDG 120 DEGS; UP TO 5000 FT. I TOOK OFF IN LNAV/VNAV TO INSURE I COULD EASILY COMPLY WITH THE LATERAL AND VERT REQUIREMENTS OF THE DEP. CLBING THROUGH 2500 FT; THE FMS COMMANDED AN INCREASE IN SPD FROM THE PROGRAMMED 200 KTS TO 250 KTS. 1/2 WAY THROUGH THE TURN TO 120 DEGS; AT APPROX 4000 FT; DEP CALLED US TO 'EXPEDITE' (TIGHTEN) OUR TURN AND TOLD US OF THE REQUIREMENT TO MAINTAIN 200 KTS OR LESS WHILE UNDER THE FLOOR OF THE CLASS B AIRSPACE. (THE CTLR LIKELY NOTED THE INCREASED RADIUS OF TURN DUE TO THE INCREASED AIRSPD). AT THIS TIME; WE WERE AT APPROX 240 KTS. I IMMEDIATELY COMPLIED. THIS IS A 'GOTCHA' FOR THIS DEP; SINCE WE TYPICALLY HAVE EVERYTHING WE NEED TO EXECUTE A DEP LISTED ON THE DEP. IN THIS CASE; WE DIDN'T REFER TO THE CLASS B AIRSPACE (ON THE SAN FRANCISCO CHART) TO SEE THAT THE FLOOR WAS UP TO 8000 FT IN THE AREA OF THIS DEP. IT DOES NOT SEEM INTUITIVE TO SEARCH FOR THE SFO CLASS B CHART TO STAY OUT OF THIS SIT. A SIMPLE NOTE ON THE LOUPE 1 DEP WOULD HELP ELIMINATE THIS SIT FOR FUTURE PLTS IN THE SAME SCENARIO.
