Narrative:

Departed brown VFR, plan was V27 8500 ft. Attempted contact with socal approach for clearance through class B airspace. No response, so backup was the VFR corridor. Socal responded as I was over the east end of coronado bridge at 3600 ft climbing to 4500 ft. Passed the end of runway 27, a number of xmissions and controller did not understand my location. He finally cleared me as requested to climb to 8500 ft through the class B airspace via V27. Controller asked if I was familiar with class B airspace. Controller gave me a telephone number and requested I call when on the ground. I called and discussed with supervisor. He did not have any details, but indicated I was well west of VFR corridor when radio contact was established. That does not make sense to me as lindbergh runway 27 and montgomery field are not likely landmarks to mistake. I do see another college on the terminal chart that I might have mistaken for qualcom stadium, but that error would have still put me in the 100/318 sector. I cannot doubt that the controller saw a real problem. This is the first time I have used the san diego VFR corridor, it is more complicated than the la's which I have used a number of times. Perhaps the freeway patterns do not look as obvious as on the chart. If I have future occasion to fly this I will file IFR instead of using the VFR corridor. (Mission bay is also a distinctive landmark.)

Title: C180 PLT DISAGREES WITH ATC'S POS THAT HE ENTERED SAN CLASS B AIRSPACE WHEN FLYING THE VFR CORRIDOR.

Narrative: DEPARTED BROWN VFR, PLAN WAS V27 8500 FT. ATTEMPTED CONTACT WITH SOCAL APCH FOR CLRNC THROUGH CLASS B AIRSPACE. NO RESPONSE, SO BACKUP WAS THE VFR CORRIDOR. SOCAL RESPONDED AS I WAS OVER THE E END OF CORONADO BRIDGE AT 3600 FT CLBING TO 4500 FT. PASSED THE END OF RWY 27, A NUMBER OF XMISSIONS AND CTLR DID NOT UNDERSTAND MY LOCATION. HE FINALLY CLRED ME AS REQUESTED TO CLB TO 8500 FT THROUGH THE CLASS B AIRSPACE VIA V27. CTLR ASKED IF I WAS FAMILIAR WITH CLASS B AIRSPACE. CTLR GAVE ME A TELEPHONE NUMBER AND REQUESTED I CALL WHEN ON THE GND. I CALLED AND DISCUSSED WITH SUPVR. HE DID NOT HAVE ANY DETAILS, BUT INDICATED I WAS WELL W OF VFR CORRIDOR WHEN RADIO CONTACT WAS ESTABLISHED. THAT DOES NOT MAKE SENSE TO ME AS LINDBERGH RWY 27 AND MONTGOMERY FIELD ARE NOT LIKELY LANDMARKS TO MISTAKE. I DO SEE ANOTHER COLLEGE ON THE TERMINAL CHART THAT I MIGHT HAVE MISTAKEN FOR QUALCOM STADIUM, BUT THAT ERROR WOULD HAVE STILL PUT ME IN THE 100/318 SECTOR. I CANNOT DOUBT THAT THE CTLR SAW A REAL PROB. THIS IS THE FIRST TIME I HAVE USED THE SAN DIEGO VFR CORRIDOR, IT IS MORE COMPLICATED THAN THE LA'S WHICH I HAVE USED A NUMBER OF TIMES. PERHAPS THE FREEWAY PATTERNS DO NOT LOOK AS OBVIOUS AS ON THE CHART. IF I HAVE FUTURE OCCASION TO FLY THIS I WILL FILE IFR INSTEAD OF USING THE VFR CORRIDOR. (MISSION BAY IS ALSO A DISTINCTIVE LANDMARK.)
