- Attain New Attitudes (Flight Path).

Question 12

The Elevators/Stabilator are used to control what?

Answer 12

Pitch Attitude of an Aircraft.

Question 13

What happens when the Control Wheel is pushed forward (name the control surface)?

Answer 13

The Elevators move down, thus the nose of the Aircraft goes down.

Question 14

What happens when the Control Wheel is pulled back (name the control surface)?

Answer 14

The Elevators move up, thus the nose of the Aircraft goes up.

Question 15

The Ailerons are used to control what?

Answer 15

Bank Attitude of an Aircraft.

Question 16

What happens when the Control Wheel is turned to the right (name the control surface)?

Answer 16

Right Aileron is raised and the left is depressed, thus turning the Aircraft to the right.

Question 17

What happens when the Control Wheel is turned to the left (name the control surface)?

Answer 17

Left Aileron is raised and the right is depressed, thus turning the Aircraft to the left.

Question 18

The Rudder is used to control what?

Answer 18

The yawing of an Aircraft.

Question 19

The Rudder is used to correct and maintain?

Answer 19

• Turbulence.
• Out-of-Balance Forces.
• Keep the nose pointing into the Relative Airflow.

Question 20

The Rudder is used to prevent an Aircraft from what when turning?

Answer 20

Slipping / Skidding (Out-of-Balance).

Question 21

What happens when using the right Rudder pedal?

Answer 21

Deflects the Rudder right causing the Aircraft to yaw right.

Question 22

What happens when using the left Rudder pedal?

Answer 22

Deflects the Rudder left causing the Aircraft to yaw left.

Question 23

True of False. The Rudder is used to turn the Aircraft?

Answer 23

False. It yaws the nose left or right.

Question 24

Name 3 factors that alter the effectiveness of the Control Surfaces?

Answer 24

• Degree of Deflection.
• Dynamic Pressure.
• Size of the Control Surface.

Question 25

What’s the secondary effect of Aileron deflection?

Answer 25

Yaw.

Question 26

What can happen if no corrective action is taken from Aircraft slipping?

Answer 26

Spiral Dive.

Question 27

How can Elevators affect Airspeed?

Answer 27

- Pitch increasing will decrease the Airspeed. | - Pitch decreasing will increase the Airspeed.

Question 28

How can an increase in Airspeed alter Pitch Trim?

Answer 28

Pitches the nose up.

Question 29

How can a decrease in Airspeed alter Pitch Trim?

Answer 29

Pitches the nose down.

Question 30

Which direction does a propeller turn from the pilot’s view?

Answer 30

Clockwise.

Question 31

Adding Power tends to Yaw the plane to which directions? And how can this be counteracted?

Answer 31

Yaw the nose to the Left and can be counteracted by using Right Rudder.

Question 32

Reducing Power tends to Yaw the plane to which directions? And how can this be counteracted?

Answer 32

Yaw the nose to the Right and can be counteracted by using Left Rudder.

Question 33

How can a pilot control Pitch Trim Tab?

Answer 33

By turning the Trim Wheel in the Cockpit.

Question 34

Where is the Pitch Trim Tab located on the Aircraft?

Answer 34

Trailing edge of the Elevator.

Question 35

What happens when forward rotation is applied to a Trim Wheel?

Answer 35

Trim Tab moves up which applies upload to the Elevator.

Question 36

What happens when backward rotation is applied to a Trim Wheel?

Answer 36

Trim Tab moves down which applies download to the Elevator.

Question 37

True of False. Trim Tabs should be used as a Primary Control?

Answer 37

False.

Question 38

When should a Pilot use Trim Tab and why?

Answer 38

After a desired attitude is established to relief the Pilot's use of the Control Wheel.

Question 39

What purpose do Flaps have (4)?

Answer 39

- Steeper Approach to Land. - Decrease Stall Speed for Slower Approach. - Improve Forward Visibility. - Improve Takeoff Performance.
