Procedure; Human Factors; Airport
I was departing on an instrument flight plan. I received my clearance from Approach while parked at the FBO; and was told to hold short of Runway 9. During taxi to Runway 9; I was monitoring Approach and CTAF simultaneously on separate radios. After stopping before the hold short markings for Runway 9; I advised Approach that I was number one for departure Runway 9. Approach advised me that there was a King Air on an instrument approach to Runway 9; and cleared me for departure; 'void if not off in five minutes'. Although monitoring both frequencies; I overheard the King Air calling final on the approach; but did not hear the distance. Because of the short void time; I incorrectly assumed that the King Air was farther out and that I had a short time to depart. I switched frequencies and called a departure on Runway 9 over the CTAF; and rolled past the hold short markings to begin takeoff. This transmission was quickly met with the King Air pilot calling his position over the runway; and announcing his intention to go-around. I aborted takeoff and announced my intent to abort on CTAF; then contacted Approach to relay this information.As PIC; I should have more closely monitored the position announcements of the King Air. With this information; I would have waited for the King Air to land; and still have been within my five minute void. In the future; I will request guidance from the controlling authority to clarify any vague information; and monitor CTAF frequencies at uncontrolled airports more closely.
A C210 pilot reported a 5 minute clearance void time led to announcing takeoff intentions on the CTAF and hearing a King Air pilot announce a go around on short final.
