The next time you check to ensure the controls are free and correct during the pretakeoff checks, think of a box. “Boxing” the controls is an efficient and professional way to complete the checklist item. Start either full right or full left with the yoke full forward. Then pull all the way aft, turn the yoke fully in the opposite direction, and then push all the way forward. Of course, glance at the aileron and elevator at each point on the box. You’ve done two things: You’ve made sure the controls are correct, and you’ve ensured they can travel fully in all directions. It also looks much better than randomly wiggling the yoke around. Try it the next time you fly.
