Q

The Rudder is used to correct and maintain?

A
  • Turbulence.
  • Out-of-Balance Forces.
  • Keep the nose pointing into the Relative Airflow.
20
Q

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

A

Slipping / Skidding (Out-of-Balance).

21
Q

What happens when using the right Rudder pedal?

A

Deflects the Rudder right causing the Aircraft to yaw right.

22
Q

What happens when using the left Rudder pedal?

A

Deflects the Rudder left causing the Aircraft to yaw left.

23
Q

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

A

False. It yaws the nose left or right.

24
Q

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

A
  • Degree of Deflection.
  • Dynamic Pressure.
  • Size of the Control Surface.
25
Q

What’s the secondary effect of Aileron deflection?

A

Yaw.

26
Q

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

A

Spiral Dive.

27
Q

How can Elevators affect Airspeed?

A
  • Pitch increasing will decrease the Airspeed.

- Pitch decreasing will increase the Airspeed.

28
Q

How can an increase in Airspeed alter Pitch Trim?

A

Pitches the nose up.

29
Q

How can a decrease in Airspeed alter Pitch Trim?

A

Pitches the nose down.

30
Q

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

A

Clockwise.

31
Q

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

A

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

32
Q

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

A

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

33
Q

How can a pilot control Pitch Trim Tab?

A

By turning the Trim Wheel in the Cockpit.

34
Q

Where is the Pitch Trim Tab located on the Aircraft?

A

Trailing edge of the Elevator.

35
Q

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

A

Trim Tab moves up which applies upload to the Elevator.

36
Q

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

A

Trim Tab moves down which applies download to the Elevator.

37
Q

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

A

False.

38
Q

When should a Pilot use Trim Tab and why?

A

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

39
Q

What purpose do Flaps have (4)?

A
  • Steeper Approach to Land.
  • Decrease Stall Speed for Slower Approach.
  • Improve Forward Visibility.
  • Improve Takeoff Performance.
40
Q

Name three types of Flaps?

A
  • Plain.
  • Split.
  • Fowler.
41
Q

Which type of Flaps are commonly used on Light Training Aircraft?

A
  • Plain.

- Split.

42
Q

How are Flaps controlled?

A

Lever or Switch in the Cockpit.

43
Q

What should a pilot take into consideration when using Flaps for Takeoff?

A

Flaps will decrease Climb performance after lift-off.

44
Q

Name three effects Lowering/Raising Flaps will have on an Aircraft (3)?

A
  • Attitude.
  • Airspeed.
  • Flight Path.
45
Q

What happens when Flaps are lowered during level flight (3)?

A
  • Lift will increase.
  • Drag will increase (Airspeed will decrease).
  • Balance of Aircraft will change.
46
Q

What happens when Flaps are raised during level flight (3)?

A
  • Lift will decrease.
  • Drag will decrease (Airspeed will increase).
  • Balance of Aircraft will change.
47
Q

To maintain Height when lowering Flaps what should a Pilot change at the same time?

A

Attitude.
