I recently flew a trip out of SJC. Evidently; the FAA has 'improved' the shape of SFO's Class B airspace. It no longer has the traditional wedding cake shape. We are not allowed to navigate using our iPads. Additionally; the defining points of the Class B are not in our database (737). So; if the FAA were looking over my shoulder; how would I ensure I comply with the 200 knot restriction? What legal method do we have of defining that airspace?
B737 Captain reported due to the updated/irregular design of the SFO CLASS B airspace; not being able to navigate with iPad; [and] lack of FMS defining points; they are unsure how to comply with FAR requirements.
