Narrative:

Departing for a routine, day VFR trip to return to pdx after a business meeting in eugene, cleared for takeoff on runway 16 with a northbound departure. Took off on runway 34 by accident with a northbound departure. I didn't catch the error until tower started moving traffic out of my way. I do this trip on a weekly basis. I am very familiar with the rtes, airports and controllers. 90% of the time, I get a runway 34 departure with a straight out, often with a tailwind takeoff. This was an 'easy' VFR flight, and my mind fell into a habit pattern that I didn't catch. I heard 'northbound departure approved' and automatically did what I usually do without thinking. My head was on what I was going to do in portland, not what I was doing then. Unfortunately, the controller was distraction by other things and didn't catch my mistake until after I was airborne. The controller remained professional throughout the incident, and reported 1 airplane on final approach that I didn't see. I maneuvered out of the traffic pattern and out of class D airspace and continued the otherwise uneventful flight to pdx. This was a breakdown in cockpit discipline. I was flying by 'autoplt' -- my mind was elsewhere. I didn't so my normal takeoff checklist, which includes verifying heading with clearance. I wasn't really paying attention to the clearance, despite an (automatic) readback that was correct. The familiarity of the flight and the lack of challenging WX conditions lulled me to the point where I was not a safe pilot. Fortunately, enough other people were looking out for me that no one got hurt.

Title: A C182 PLT TAKES OFF ON RWY 34 WHEN HE HAD BEEN CLRED FOR TKOF ON RWY 16 AT EUG, OR.

Narrative: DEPARTING FOR A ROUTINE, DAY VFR TRIP TO RETURN TO PDX AFTER A BUSINESS MEETING IN EUGENE, CLRED FOR TKOF ON RWY 16 WITH A NBOUND DEP. TOOK OFF ON RWY 34 BY ACCIDENT WITH A NBOUND DEP. I DIDN'T CATCH THE ERROR UNTIL TWR STARTED MOVING TFC OUT OF MY WAY. I DO THIS TRIP ON A WKLY BASIS. I AM VERY FAMILIAR WITH THE RTES, ARPTS AND CTLRS. 90% OF THE TIME, I GET A RWY 34 DEP WITH A STRAIGHT OUT, OFTEN WITH A TAILWIND TKOF. THIS WAS AN 'EASY' VFR FLT, AND MY MIND FELL INTO A HABIT PATTERN THAT I DIDN'T CATCH. I HEARD 'NBOUND DEP APPROVED' AND AUTOMATICALLY DID WHAT I USUALLY DO WITHOUT THINKING. MY HEAD WAS ON WHAT I WAS GOING TO DO IN PORTLAND, NOT WHAT I WAS DOING THEN. UNFORTUNATELY, THE CTLR WAS DISTR BY OTHER THINGS AND DIDN'T CATCH MY MISTAKE UNTIL AFTER I WAS AIRBORNE. THE CTLR REMAINED PROFESSIONAL THROUGHOUT THE INCIDENT, AND RPTED 1 AIRPLANE ON FINAL APCH THAT I DIDN'T SEE. I MANEUVERED OUT OF THE TFC PATTERN AND OUT OF CLASS D AIRSPACE AND CONTINUED THE OTHERWISE UNEVENTFUL FLT TO PDX. THIS WAS A BREAKDOWN IN COCKPIT DISCIPLINE. I WAS FLYING BY 'AUTOPLT' -- MY MIND WAS ELSEWHERE. I DIDN'T SO MY NORMAL TKOF CHKLIST, WHICH INCLUDES VERIFYING HDG WITH CLRNC. I WASN'T REALLY PAYING ATTN TO THE CLRNC, DESPITE AN (AUTOMATIC) READBACK THAT WAS CORRECT. THE FAMILIARITY OF THE FLT AND THE LACK OF CHALLENGING WX CONDITIONS LULLED ME TO THE POINT WHERE I WAS NOT A SAFE PLT. FORTUNATELY, ENOUGH OTHER PEOPLE WERE LOOKING OUT FOR ME THAT NO ONE GOT HURT.
