Turns around a point fail on checkrides because of one geometry problem: students react to wind drift instead of anticipating it. Here's how bank angle and crab work together.

Master turns around a point by understanding how wind changes your groundspeed and bank angle - steepest downwind, shallowest upwind, all the way around.
