THE CONTROL YOKE
This control moves like a steering wheel on a car except it turns only about a 1/4 turn in each direction from neutral. It can also move forwards and backwards. The backwards and forwards movement controls the elevators. The steering wheel type motion controls the ailerons. The elevators control the pitch (nose up or nose down). Easing the yoke forward puts the nose down and thereby increases the aircraft speed (like a car going down hill). Easing the yoke back past the neutral position will put the nose up and decrease the speed (like a car going up hill). Although it appears that this control would be used to cause the aircraft to climb or descend this is not strictly true. In fact it is the power setting (throttle) that assists the aircraft to climb and descend. When the wheel part of the yoke is turned to the left the aileron on the right wing moves down and the aileron on the left wing moves upwards. This results in more lift for the right wing and less for the left wing, causing the aircraft to bank and turn to the left. It is this control, co-ordinated with the rudder which is used to turn the aircraft.
