How is the elevator operated in a Cessna 172?

The elevator in a Cessna 172 is operated through a yoke. The yoke is a control device that the pilot uses to influence the pitch of the aircraft. When the pilot pushes forward on the yoke, the elevator is positioned downward, causing the aircraft’s nose to drop, which results in a descent. Conversely, pulling back on the yoke raises the elevator, causing the nose to rise and the aircraft to climb. This direct connection allows for precise control over the aircraft’s altitude and attitude during flight.

The other options are not involved in the operation of the elevator. Foot pedals are used to control the rudder for yaw movements rather than pitch. Flaperons, which are a combination of flaps and ailerons, are used for roll control and help manage lift during takeoff and landing but do not control the elevator. The throttle lever is used to control engine power, which affects speed and climb performance but does not directly operate the elevator. Thus, the yoke is the correct and necessary instrument for elevator control in a Cessna 172.
