9.G:
And, coming from PDZ or PRADO your are at 4,000, well below the airspace used by a different SoCal sector for LA arrivals from the east. Arriving from the NW over POM, though, the MEA of the airway (prior to HASSA) if continued, would fly directly into the LA arrival sector. The Class B airspace gives a good "hint" about all of that.
Anyone interested can go to skyvector.com, "go" to POM then select the Los Angeles TAC to see the Class B airspace clearly.
