Airspace Structure; Procedure
This is more a safety concern report. The RAZZR arrival into SJC is one of the new RNAV arrivals. When landing runway 12L/R the profile has you descending over EDMND fix at or above 5;400 feet at 230 KIAS. The next fix is JESEN with an altitude of 4;000 feet according the STAR plate they are 4.3 NM apart. That would be a close but possible descent if planned properly. Except in between the two; 1 nm past EDMND the aircraft will pass under Class B airspace from SFO. It isn't possible to cross a fix at 230 KIAS; in one mile slow to 200 to comply with FAR speed limits and descend to meet the next altitude. I tried to comply with all and couldn't do it; even with full spoilers out. There is a NOTAM out regarding speed at ZORSA at 200 KIAS so this would appear to be a known problem. The TEKKY departure has a similar problem showing a max speed of 230 KIAS while under B airspace.
Arrival and departures at SJC operate under the SFO Class B and crews need to observe the 200 knot airspeed restriction.
