C182 PLT AT NON TWR ARPT DEPARTS WITH C152 ON FINAL FORCING A GAR.

Narrative

HAD BEEN ASKED BY ATC TO DEPART VFR AND OPEN IFR FLT PLAN IN THE AIR DUE TO TFC ENRTE TO A NEARBY ARPT. I TAXIED TO THE HOLD SHORT LINE IN FRONT OF A BARON DOING A RUN-UP ON THE TXWY. I WAS SQUARE TO THE HOLD SHORT LINE. I LOOKED L TOWARD THE APCH END OF THE RWY AND SAW NOTHING. AS I TAXIED ONTO THE RWY I NOTICED THAT I WAS STILL ON CLRNC DELIVERY AND NOT THE CTAF. WHEN I SWITCHED TO CTAF I HEAR A C152 CALL A FINAL TO RWY 17. FROM PREVIOUS EXPERIENCE; I FELT I HAD PLENTY OF TIME TO TKOF; SO I APPLIED FULL THROTTLE AS I WAS APCHING CTRLINE. I THEN HEAR THE C152 CALL SHORT FINAL. FEELING THAT THERE WAS NOT ENOUGH TIME TO GET OFF THE RWY; I CONTINUED MY TKOF AND HEARD THE C152 ANNOUNCE A GAR. WHEN I GOT BACK TO THE ARPT LATER THAT DAY; I TALKED TO THE INSTRUCTOR IN THE PLANE AND EXPLAINED WHAT HAPPENED. ONLY THEN DID I LEARN HOW CLOSE THE C152 ACTUALLY WAS TO THE RWY. I USUALLY DON'T STOP SQUARE ON THE HOLD SHORT LINE BUT ANGLE THE PLANE 30-45 DEGS TOWARD APCHING TFC. I DIDN'T EVEN CONSIDER AT THE TIME; THE OPTION OF JUST STOPPING MY PLANE ON THE RWY. HUMAN PERFORMANCE CONSIDERATIONS: I FELT A LITTLE PRESSURE TO DEPART DUE TO THE BARON BEHIND ME. I PROBABLY WAS UNDER SOME TENSION AS MY WIFE WAS WITH ME AND WE HAD BEEN TALKING OF A DIVORCE FOR THE LAST MONTH. MY PERCEPTION OF HAVING ENOUGH TIME TO TKOF AFTER A PLANE HAD CALLED A FINAL APCH WAS IN ERROR. AS IT TURNED OUT; THAT INSTRUCTOR LIKES TO KEEP STUDENTS CLOSE TO THE TFC PATTERN SO AS TO TEACH THEM A PATTERN THAT WOULD BE WITHIN GLIDE DISTANCE SHOULD THE ENG FAIL. I REALIZE NOW THAT I SHOULD HAVE ANGLED MY PLANE TOWARD THE APCHING TFC PATTERN AND ALSO THAT I COULD SIMPLY STOP ON THE RWY ONCE I BECOME AWARE OF A TFC CONFLICT.
