Three Axes of Flight Pitch Roll Yaw
CONTROL SURFACES
Movable flaps on the wing, horizontal and vertical stabilizer
“Guide” the aircraft through the air
Pitch
Pitch - up and down movement of the aircraft
- controlled by elevator The elevator is attached to the trailing edge of the horizontal stabilizer
Pitch
Roll
Roll - “tilting” left and right
of the aircraft Controlled by the ailerons Ailerons are attached the trailing edge of the wings near the tips
Banking
Yaw
Yaw - the left and right pointing of the aircraft.
- controlled by the rudder The rudder is attached to the trailing edge of the vertical stabilizer
Yaw
TRIM TABS
Small tabs on the control surfaces
Help to reduce amount of force needed on the controls Reduces pilot work load Almost like cruse control on a car
TRIM TABS
Found on one or more control surfaces
Balance the aircraft When trimmed, the pilot can remove his hands from the controls Only minor corrections are needed by the pilot
PITCH TRIM
ROLL TRIM
YAW TRIM
AILERON DRAG AFFECTS YAW
BALANCED FLIGHT
Requires forces in all three axis to be balanced
Control surfaces and trim tabs accomplish this task
