C182 PLT INCURRED MSN CLASS C AIRSPACE.

Narrative

A SERIOUS VIOLATION OF MADISON; WI; CLASS C AIRSPACE BY APPROX .4 NM AT ABOUT 2000 FT MSL. WE WERE ON A PLANNED CAP TRAINING/DEMONSTRATION FLT. WE'D FILED A ROUND ROBIN VFR FLT PLAN WITH GREEN BAY FSS; WAUSAU TO PORTAGE AND BACK. I ABSOLUTELY HAD NO INTENTION OF GOING NEAR MADISON; SO DID NOT TUNE IN APCH. WE RECEIVED A SURPRISE ADDITIONAL TRAINING ASSIGNMENT. WHERE'S THAT? WE WERE TOLD APPROX 18 NM ON THE 310-315 DEG RADIAL OF THE 108.6 VOR. WHILE INTERCEPTING +/-2000 FT MSL I NOTICED 4.6 NM ON THE DME AND TURNED AWAY. AFTER LNDG AT PORTAGE (C47) WE HAD A BAD TIME TELEPHONING MSN. NEED TO BE MORE VIGILANT. NOT AGAIN! NEED TO TAKE MORE TIME TO REORIENT AND PLAN; BEFORE DEPARTING YOUR KNOWN POS FOR A NEW ONE! SHOULD HAVE; AND COULD HAVE; SIMPLY FLOWN THE 18 NM ARC AROUND TO THE 315 DEG RADIAL AREA FROM THE +/-340 DEG RADIAL I WAS ON VERSUS THE MIND SET OF GOING TO THE VOR AND BACK OUT. THE CAP IS ALL SAFETY. I ATTEND VARIOUS SAFETY MEETINGS YRLY; AND READ SUCH PUBLICATIONS AS AOPA PLT; FLYING; NASA/ASRS CALLBACK; IFR REFRESHER; ETC. I'VE BROUGHT UP MY MISTAKE WITH FELLOW PLTS AND IT HAS BEEN WELL DISCUSSED. MUST KEEP TRYING AND LEARNING.
