Air Transportation How Airplanes Fly
Objectives 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.
Flight Vocabulary Here are the terms you will be learning about during this unit Relative wind Angle of Incidence Angle of attack Induced lift Dynamic lift Bernoulli Principle • Lift • Drag • Gravity • Thrust • Aerodynamic • Rudder • Aileron • Cockpit • Fuselage • Airfoil • Camber • Chord
Elevators Elevators control “Pitch” around the Lateral axis
Steering • To change the pitch • Raise or lower the elevator • To ASCEND (go up) • RAISE the elevator. • to DESCEND (go down) • LOWER the elevator.
Aileron Aileron Ailerons control “Roll” around the Longitudinal axis
Steering • 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 Rudder controls “Yaw” around the vertical axis
Steering • 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
Vertical Axis Motion: Yaw Controlled by the Rudder
Lateral Axis Motion: Pitch Controlled by the Elevators
Longitudinal Axis Motion: Roll Controlled by the Ailerons
Vertical Axis Motion: Yaw Controlled by the Rudder Center of Gravity Longitudinal Axis Motion: Roll Controlled by the Ailerons Lateral Axis Motion: Pitch Controlled by the Elevators
