  • Where are spoilers?
    extend from the top surface of a wing
  • What is 'Dutch roll"?
    Uncomfortable oscillations that can occur during the flight; usually a type of aircraft motion consisting of an out-of-phase combination of "tail-wagging" (yaw)
  • Where are flaps?
    inboard two-thirds of the wing trailing edge
  • What is yaw?
    movement about the normal axis
  • What movement are ailerons responsible for?
    roll
  • Where are ailerons?
    outboard third of the trailing edge of a wing
  • What movement is the elevator responsible for?
    pitch
  • How do we call a back edge of an airfoils?
    trailing edge
  • What is roll?
    movement about the longitudinal axis
  • What is trim?
    To adjust the aerodynamic forces on the control surfaces so that the aircraft maintains the set attitude without any control input
  • What is pitch?
    movement about the lateral axis
  • Where is elevator?
    trailing edge of the tailplane
  • Where are slats?
    on the leading edge of a wing
  • What does a pilot need to do to roll a plane?
    They need to deflect ailerons, so a pilot has to move a yoke or a stick left or right.
  • What movement is rudder responsible for?
    yaw
  • What does a pilot need to do to yaw a plane?
    They need to deflect a rudder, so a pilot has to move rudder pedals.
  • What are speed-brakes responsible for?
    reducing lift and increasing drag
  • What does a pilot need to do to pitch a plane?
    they need to deflect an elevator, so a pilot has to move a yoke or a stick forward or aft.
  • How do we call a front edge of an airfoils?
    leading edge
  • Name 3 secondary flight control surfaces.
    flaps, slats, spoilers
  • Where is rudder?
    Trailing edge of the fin (vertical stabilizer)
  • What are flaps responsible for?
    increasing lift for a given speed
  • What are slats responsible for?
    increasing wing area and camber = increasing overall lift
  • Name primary flight control surfaces
    elevator, ailerons, rudder
