Can anyone regularly flying in southern California tell me whether or not there have been any large airspace revisions in the past couple of years?... Again, I just want to avoid the San Diego class C and LAX class B airspaces.
Well, Joe, if you think that SD is a Class C, then I'd say yes, there have been some pretty large revisions, because SD is a Class B, not a C.
Joe, you're a friend (and obviously as cheap as I am if not more so), but I will have to admonish you here and say either update the GPS or get a set of LA sectional and TAC charts ($11.85 for both from iPilot), or stay out of the LA airspace. You cannot (however legal it may or may not be, and even if between the Class B airspaces or over the Class C's) safely and rationally fly around the incredibly complex airspace south of the San Gabriel Mountains without current charting information.
Bite the bullet - spend the $11.85 - I know that paper charts are a PITA in a LE - they're enough of a PITA in the COZY. But you really don't have a choice - it's either that, or the GPS update. You've got to know the Class B boundaries, on top, bottom and sides. As well as the VFR corridors over LAX and the "tunnel" in the SD Class B. Plus, the Class C's over Ontario and Burbank, and the innumerable Class D's. I've flown in or around most of the Class B's in the US - the LA/SD combination is easily the most complex one there is, even including the BOS/NY/DC corridor.
