Narrative:

I departed vny airport en route to tij on VFR conditions. My plan was to fly the VFR corridor through the lax class B airspace. After departing van nuys airport I flew towards santa monica airport to intercept SVFR corridor. After takeoff visibility deteriorated rapidly to the point I had no ground reference. I called socal approach and received a squawk code and asked for vectors to SVFR corridor. Waiting for vectors I kept flying on my present heading. When the controller finally got back to me he said I had entered the class B airspace. I then turned toward the oceanside VOR and flew to it and proceeded on my way. I believe the situation occurred because of 3 things: visibility was very poor due to la smog, so seeing the coastline was impossible. The coast SVFR corridor was not on a VOR radial so it would be easy to follow, the controllers were so busy that you could not break in to ask for information until it was too late. My suggestion as to how to help would be to mark charts clearly with radials for SVFR rtes, not with landmarks lie north of shoreline or hwys, this way if areas like lax where visibility is so poor, you would be able to positively navigation your way through the airspace.

Title: PVT PLT, TRYING TO NAV BY VISUAL GND REF, LOW VISIBILITY, INADVERTENTLY FLEW INTO CLASS B AIRSPACE. APCH CTLR ADVISED HIM OF SUCH AND HE CORRECT OUT OF CLASS B.

Narrative: I DEPARTED VNY ARPT ENRTE TO TIJ ON VFR CONDITIONS. MY PLAN WAS TO FLY THE VFR CORRIDOR THROUGH THE LAX CLASS B AIRSPACE. AFTER DEPARTING VAN NUYS ARPT I FLEW TOWARDS SANTA MONICA ARPT TO INTERCEPT SVFR CORRIDOR. AFTER TKOF VISIBILITY DETERIORATED RAPIDLY TO THE POINT I HAD NO GND REF. I CALLED SOCAL APCH AND RECEIVED A SQUAWK CODE AND ASKED FOR VECTORS TO SVFR CORRIDOR. WAITING FOR VECTORS I KEPT FLYING ON MY PRESENT HDG. WHEN THE CTLR FINALLY GOT BACK TO ME HE SAID I HAD ENTERED THE CLASS B AIRSPACE. I THEN TURNED TOWARD THE OCEANSIDE VOR AND FLEW TO IT AND PROCEEDED ON MY WAY. I BELIEVE THE SIT OCCURRED BECAUSE OF 3 THINGS: VISIBILITY WAS VERY POOR DUE TO LA SMOG, SO SEEING THE COASTLINE WAS IMPOSSIBLE. THE COAST SVFR CORRIDOR WAS NOT ON A VOR RADIAL SO IT WOULD BE EASY TO FOLLOW, THE CTLRS WERE SO BUSY THAT YOU COULD NOT BREAK IN TO ASK FOR INFO UNTIL IT WAS TOO LATE. MY SUGGESTION AS TO HOW TO HELP WOULD BE TO MARK CHARTS CLRLY WITH RADIALS FOR SVFR RTES, NOT WITH LANDMARKS LIE N OF SHORELINE OR HWYS, THIS WAY IF AREAS LIKE LAX WHERE VISIBILITY IS SO POOR, YOU WOULD BE ABLE TO POSITIVELY NAV YOUR WAY THROUGH THE AIRSPACE.
