Narrative:

Climbing to 4500 ft I overshot my target altitude and entered lax class b airspace. Penetration was discovered at 5400 ft and an immediate descent begun. Detection was a result of GPS alert. Factors included frequent IFR flight over the same route deferring altitude to 'as assigned,' concurrent communication with hhr FSS regarding opening of VFR flight plan which they did not have (duat forwarded it to ral FSS), preoccupation with GPS operation. Conclusion: VFR flight can be 'foreign' to IFR pilots if not done often. VFR freedom from ATC IFR routing/altitude, plus needing to open the flight plan, make VFR flight more difficult than IFR flight (in VMC).

Title: A VFR C182 PLT CLBS INTO THE CLASS B OF SCT WHILE TALKING WITH FSS NW OF SLI, CA.

Narrative: CLBING TO 4500 FT I OVERSHOT MY TARGET ALT AND ENTERED LAX CLASS b AIRSPACE. PENETRATION WAS DISCOVERED AT 5400 FT AND AN IMMEDIATE DSCNT BEGUN. DETECTION WAS A RESULT OF GPS ALERT. FACTORS INCLUDED FREQUENT IFR FLT OVER THE SAME RTE DEFERRING ALT TO 'AS ASSIGNED,' CONCURRENT COM WITH HHR FSS REGARDING OPENING OF VFR FLT PLAN WHICH THEY DID NOT HAVE (DUAT FORWARDED IT TO RAL FSS), PREOCCUPATION WITH GPS OP. CONCLUSION: VFR FLT CAN BE 'FOREIGN' TO IFR PLTS IF NOT DONE OFTEN. VFR FREEDOM FROM ATC IFR ROUTING/ALT, PLUS NEEDING TO OPEN THE FLT PLAN, MAKE VFR FLT MORE DIFFICULT THAN IFR FLT (IN VMC).
