We noted the EMZOH3 STAR places the aircraft below the San Francisco Class B airspace. It does not indicate this airspace; and the aircraft's flight management system does not take the associated speed limit into account (the Legs page displays the normal 240 knot speed at MYNEE and later fixes). We programmed the required 200 knot speed; but recommend this should be coded into the arrival. A busy crew could easily miss the specific altitudes of the Class B shelf. On a previous flight; the pilot with whom I was flying said he was slowing to comply with this requirement; and the Captain said '...I've never had a problem with the Class B before;' indicating that he didn't agree with the deceleration; and that the first officer should have maintained 250 knots. I recommend charting improvements to indicate Class B airspace on STAR. This arrival places aircraft below Class B.We could address this via bulletins; but I believe these are not permanent solutions. A note on the station page would be more effective (and currently exists); but publishing (and coding) the relevant speed would be best; in my opinion.
An air carrier pilot reported the EMZOH3 STAR to OAK published speed is above the speed limit for being underneath the SFO Class B airspace.
