Narrative:

In this particular situation, it appeared that takeoffs and landings were alternating. After the previous landing aircraft had passed, I pulled past the hold-short line but stayed at right angles to the runway to monitor both the previous aircraft and incoming traffic. Aircraft #2 had just announced his base turn. I stayed in this position until the previous landing aircraft had left the runway. I then verified the localizer of aircraft #2, determined that aircraft #2 had turned final but appeared a safe distance away, and believed that my current position between the hold-short line and the runway proper would, if maintained, force aircraft #2 into a go-around. At this point, I simultaneously announced my takeoff and began to roll for an immediate takeoff, with the belief that doing so might avoid forcing aircraft #2 to go around. This action was met with an immediate declaration by aircraft #2 that he was on short and final and that I was not watching traffic. I departed upwind without seeing aircraft #2 again, although the aircraft #2 pilot continued to object to my takeoff decision on the CTAF. The decision to begin my takeoff roll was clearly ill-advised, although I don't believe I ever created an actual collision risk. At the time, I believed that I was already blocking the runway, and that to remain stationary would create a bigger hazard. I do not intend to put myself in the position again of being beyond the hold-short line.

Title: A PA32 PLT, TAXIING FOR TKOF AT F70, TOOK THE RWY AND DEPARTED AHEAD OF LANDING TFC.

Narrative: IN THIS PARTICULAR SIT, IT APPEARED THAT TKOFS AND LANDINGS WERE ALTERNATING. AFTER THE PREVIOUS LANDING ACFT HAD PASSED, I PULLED PAST THE HOLD-SHORT LINE BUT STAYED AT R ANGLES TO THE RWY TO MONITOR BOTH THE PREVIOUS ACFT AND INCOMING TFC. ACFT #2 HAD JUST ANNOUNCED HIS BASE TURN. I STAYED IN THIS POS UNTIL THE PREVIOUS LANDING ACFT HAD LEFT THE RWY. I THEN VERIFIED THE LOC OF ACFT #2, DETERMINED THAT ACFT #2 HAD TURNED FINAL BUT APPEARED A SAFE DISTANCE AWAY, AND BELIEVED THAT MY CURRENT POS BTWN THE HOLD-SHORT LINE AND THE RWY PROPER WOULD, IF MAINTAINED, FORCE ACFT #2 INTO A GO-AROUND. AT THIS POINT, I SIMULTANEOUSLY ANNOUNCED MY TKOF AND BEGAN TO ROLL FOR AN IMMEDIATE TKOF, WITH THE BELIEF THAT DOING SO MIGHT AVOID FORCING ACFT #2 TO GO AROUND. THIS ACTION WAS MET WITH AN IMMEDIATE DECLARATION BY ACFT #2 THAT HE WAS ON SHORT AND FINAL AND THAT I WAS NOT WATCHING TFC. I DEPARTED UPWIND WITHOUT SEEING ACFT #2 AGAIN, ALTHOUGH THE ACFT #2 PLT CONTINUED TO OBJECT TO MY TKOF DECISION ON THE CTAF. THE DECISION TO BEGIN MY TKOF ROLL WAS CLEARLY ILL-ADVISED, ALTHOUGH I DON'T BELIEVE I EVER CREATED AN ACTUAL COLLISION RISK. AT THE TIME, I BELIEVED THAT I WAS ALREADY BLOCKING THE RWY, AND THAT TO REMAIN STATIONARY WOULD CREATE A BIGGER HAZARD. I DO NOT INTEND TO PUT MYSELF IN THE POS AGAIN OF BEING BEYOND THE HOLD-SHORT LINE.
