What Am I: Yank and bank

The yoke is where the action is

Starting since at least the Curtiss 1 in 1909, aircraft have featured a yoke, or control wheel, to bank the airplane with the ailerons and pitch it with the elevator. Those early aircraft featured what approximated a car steering wheel, whereas most of today’s aircraft have half a wheel. The function is the same. Push forward and the aircraft goes down, pull back and it goes up. Turn the yoke left and the aircraft banks left, turn right and it banks right. This type of aircraft control corresponds closely to what pilots are used to experiencing on the ground.

In typical light aircraft with dual yokes, the yokes are directly connected so that moving one moves the other. Behind each tube that comes out of the panel is a sprocket, and a chain connects the sprockets that drive both simultaneously.
