Narrative:

ATIS informed landing 31, departing 35. Ground instructed me to taxi to 35. Being unfamiliar with the airport, I followed the signs and did my run up at the hold short line. Upon telling tower I was ready on 35, I was told to taxi into position and hold. I read back the clearance and began taxiing. As I began my turn to straighten out on the runway, I was told to fly runway heading and I was cleared for takeoff. Without stopping, I accelerated and began my takeoff roll. Tower asked me if I had understood my clearance (they were looking for me) when, upon sighting me told me that I had taken off on a closed runway (runway 3.) at that point, I had already rotated and was airborne. I do not recall seeing an X on the runway. I had aligned my compass with my directional gyroscope during my runup, but because my 'position and hold' clearance was superseded with a takeoff clearance, I did not double check the heading on the runway, as I should have. I also should have become more familiar with the airport diagram to know that both runways 35 and 3 originated very close to one another. Although it is not their responsibility, I believe that if tower had looked for me before issuing the takeoff clearance rather tan after, he would have seen that I was lining up on the wrong runway.

Title: CHARTER PLT TKOF ON WRONG RWY.

Narrative: ATIS INFORMED LNDG 31, DEPARTING 35. GND INSTRUCTED ME TO TAXI TO 35. BEING UNFAMILIAR WITH THE ARPT, I FOLLOWED THE SIGNS AND DID MY RUN UP AT THE HOLD SHORT LINE. UPON TELLING TWR I WAS READY ON 35, I WAS TOLD TO TAXI INTO POS AND HOLD. I READ BACK THE CLRNC AND BEGAN TAXIING. AS I BEGAN MY TURN TO STRAIGHTEN OUT ON THE RWY, I WAS TOLD TO FLY RWY HDG AND I WAS CLRED FOR TKOF. WITHOUT STOPPING, I ACCELERATED AND BEGAN MY TKOF ROLL. TWR ASKED ME IF I HAD UNDERSTOOD MY CLRNC (THEY WERE LOOKING FOR ME) WHEN, UPON SIGHTING ME TOLD ME THAT I HAD TAKEN OFF ON A CLOSED RWY (RWY 3.) AT THAT POINT, I HAD ALREADY ROTATED AND WAS AIRBORNE. I DO NOT RECALL SEEING AN X ON THE RWY. I HAD ALIGNED MY COMPASS WITH MY DIRECTIONAL GYROSCOPE DURING MY RUNUP, BUT BECAUSE MY 'POSITION AND HOLD' CLRNC WAS SUPERSEDED WITH A TKOF CLRNC, I DID NOT DOUBLE CHK THE HDG ON THE RWY, AS I SHOULD HAVE. I ALSO SHOULD HAVE BECOME MORE FAMILIAR WITH THE ARPT DIAGRAM TO KNOW THAT BOTH RWYS 35 AND 3 ORIGINATED VERY CLOSE TO ONE ANOTHER. ALTHOUGH IT IS NOT THEIR RESPONSIBILITY, I BELIEVE THAT IF TWR HAD LOOKED FOR ME BEFORE ISSUING THE TKOF CLRNC RATHER TAN AFTER, HE WOULD HAVE SEEN THAT I WAS LINING UP ON THE WRONG RWY.
