What is the effect of moving the control yoke backwards?

Moving the control yoke backwards causes the elevator to deflect upwards. This upward deflection of the elevator increases the angle of attack of the aircraft's tail. As a result, the aircraft's nose is pitched up, which typically leads to an increase in altitude or a climb if other factors such as airspeed and engine power are sufficient.

This action alters the aerodynamic forces acting on the aircraft and changes its attitude in the vertical plane, making the aircraft climb or gain altitude. Understanding this relationship is essential for pilots, as the control yoke serves as the primary means of controlling pitch attitude during flight.
