　　Skid resistance ability is one of the most important characteristics for performance of airport pavement safety. It not only affects the braking ability of aircrafts, but also improves the controlling of aircrafts direction that is affected by crossing wind or engine failure. Therefore, a periodical measurement of runway friction resistance is rather important. The objective of this paper is to develop the appropriate threshold value for runway skid number from the most critical view point: aircraft takeoff abortion.
　　Questionnaires collected from pilots indicated that the pavement skid number has a great contribution to the aircraft braking ability, especially under the takeoff abortion situation. In this paper, a Boeing 747-400 takeoff abortion process is simulated at the 06/24 runway of Chiang Kai-Shek International Airport, and the friction threshold value is derived by energy transmission theory.
