Effect of wind during a turn. straight-line ground reference. Once a straight-line ground  reference is established, the pilot makes a 360° constant  medium banked turn. As the airplane completes the 360°  turn, it should return directly over the straight-line ground  reference but downwind from the starting point. Choosing a  straight-line ground reference that has a crosswind, and using  the same 360° constant medium-banked turn, demonstrates  how the airplane drifts away from the reference even as the  pilot holds a constant bank angle. In both examples, the path  over the ground is an elongated circle, although in reference  to the air, the airplane flew a perfect continuous radius. In order to compensate for the elongated, somewhat circular  path over the ground, the pilot must adjust the bank angle  as the groundspeed changes throughout the turn. Where  groundspeed is the fastest, such as when the airplane is  6-5
