The Empennage | How Stabilizers Reduce Unwanted Axial Movement | How the Rudder Produces Yaw | How the Elevator Controls Pitch | Recap: Eo M231.01 & Eo M231.03 |
---|---|---|---|---|
An aircraft’s empennage is very often called the...
Tail section
|
The control surfaces are held straight
by...
The passing wind.
|
Where is the rudder located?
At the back of the empennage.
|
Where is the elevator control surface located?
The elevator control surface is located on the trailing edge of the horizontal stabilizer.
|
What are the four forces of flight?
Lift, Weight, Thrust, Drag.
|
The vertical stabilizer on the empennage.
The fin
|
Air moving past the flat surfaces of the stabilizers tends to ____ a change of direction.
Resist
|
What is the rudder used for?
To produce controlled yaw by rotating the aircraft about its vertical (yaw) axis.
|
There is normally a ___ and a ____ section in the elevator.
Left and Right
|
What are the two propelling forces of flight?
Lift and Thrust.
|
The horizontal stabilizer on the empennage.
The tailplane
|
What axial movement does the vertical stabilizer or fin reduce?
The vertical stabilizer reduces unwanted roll and unwanted yaw.
|
The rudder is located at the very back of the aircraft, hinged to the ______ of the fin.
Trailing Edge
|
Raising the elevator into the moving air above the tailplane will push the empennage...
Down.
|
What are the two burdening forces of flight?
Weight and Drag.
|
Which two moveable control surfaces are located in the empennage?
The rudder and elevator.
|
What axial movement does the horizontal stabilizer or tailplane reduce?
The horizontal stabilizer reduces unwanted roll and unwanted pitch.
|
When the bar or pedals are level the rudder is...
Straight
|
How does the pilot operate the elevator?
The pilot pushes on the control column to descend and pulls back to climb.
|
What is the equilibrium?
When the forces are at an balance and none are acting over the other.
|
What axial movements do the elevator and the rudder produce?
The rudder changes yaw around the vertical axis and the elevator changes pitch around the lateral axis.
|
How do stabilizers reduce unwanted axial movements?
Air moving past the flat stabilizer surfaces tends to resist any change of motion.
|
What controls the rudder?
A set of pedals in the cockpit.
|
What axial movement does the elevator control?
The elevator controls pitch around the aircraft’s lateral axis.
|
What are the axial movements and the each of the axis?
Roll, Longitudinal Axis. Pitch, Lateral Axis. Yaw, Vertical Axis.
