How Airplanes FlyHow Airplanes Fly

After this lesson you will be able to Define terms associated with flight Name and describe the 4 forces acting on a

plane. Name and describe the motions of a plane,

the control surfaces that control these motions and the axes around which they rotate.

Here are the terms you will be learning about during this unit

Elevators control “Pitch” around the Lateral axis

Elevators

To change the pitch Raise or lower the elevator

To ASCEND (go up) RAISE the elevator.

to DESCEND (go down) LOWER the elevator.

Ailerons control “Roll” around the Longitudinal axis

Aileron

Aileron

To Roll the plane Change the ailerons on the wings

To roll RIGHT, Put the RIGHT aileron UP and left aileron

down.To roll LEFT,

Put the LEFT aileron UP and right aileron down.

Rudder controls “Yaw” around the vertical axis

Rudder

To change the yaw Move the rudder right or left

To turn RIGHT, turn the rudder to the right

To turn LEFT, turn the rudder to the left
