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
