Ski jumpers have been struggling to control their V-style ski-opening angle from time to time in order to make the longest flight distance. They have acquired their own angle control techniques based on their experiences and coaches' advice. It has been desired to make clear how to control V-style ski-opening angle on the basis of aerodynamics as well as empirical knowledge. This is thus the very objective of this study. In this study, the ski-opening angle is chosen as a control parameter as well as the angle of attack or the forward leaning angle for the maximum flight distance. It is found that the ski-opening angle increases with the increase of time in the first half of the flight, and it slightly decreases after the maximum value of 38° is attained in the second half. The optimized flight distance is comparable with the winner's one
