  • Principles of Flight Chapter 3 – Stability and Control
  • Stability
    • An Aircraft must be stable in flight in order to perform well
    • Also we must be able to control the aircrafts movement.
  • Yaw
    • Aircraft turns left or right
    View slide
  • Controlling - Yaw
    • Using the rudder pedals the pilot moves the rudder left or right to change the aircrafts direction.

  • Pitch
    • Aircrafts noses Up or Down
  • Controlling - Pitch
    • Moving the stick forwards/back lifts or lowers the aircrafts nose by generating more or less lift at the tail
    • It uses Elevators to do this
  • Roll
    • Aircraft “twists”
  • Controlling - Roll
    • Moving the stick left/right rolls the aircraft by generating more lift on one side.
    • It does this by moving flaps known as Ailerons
  • Trimming
    • When an aircraft pitches involuntarily it needs to be trimmed.
    • Small flaps mounted on the Elevators called “Trimming tabs” jut out from the elevators to increase the camber.
    • Aileron and Rudder trimming is the same
  • Flaps
    • Flaps increase wing camber and/or area
  • Flaps
    • Flaps allow aircraft to fly safely at slow speeds
    • They are mounted on the inside of the wings and can hinge down to increase lift at slow speeds
  • Slats
    • Like flaps at the front of the wing
    • They slide out of the leading edge and are used at low speed
    • Positioned on leading edge of the wing
