Question 1 of 12

1. Question
The maximum flap extension speed is known as:
- VFE
- VNE
- VS
- VLE
Correct

Incorrect
Question 2 of 12

2. Question
Extending flaps increases the lift created. One of the reasons this occurs is because:
- The aerofoil camber is increased
- The form drag decreases
- The angle of attack decreases
- The induced drag decreases
Correct

Incorrect
Question 3 of 12

3. Question
Which of the following statements regarding flaps is the most correct?
- Retracting flaps very close to the ground is not advisable as the loss of lift can cause a sudden increase in descent rate
- The flaps should be retracted immediately when initiating a go-around in order to reduce drag and maximise the rate of climb
- In the case of an emergency, flaps can be fully extended rapidly at any airspeed as they are designed to withstand the forces at all airspeeds below VNE
- Flaps, also known as speed brakes, are primarily used to slow the aircraft down during the approach to land
Correct

Incorrect
Question 4 of 12

4. Question
The use of a small flap setting instead of zero flap for takeoff and climb results in:
- a shorter takeoff ground run and shallower climb angle
- a shorter takeoff ground run and steeper climb angle
- a longer takeoff ground run and shallower climb angle
- a longer takeoff ground run and steeper climb angle
Correct

Incorrect
Question 5 of 12

5. Question
How do lift and drag change when setting flaps to a lower position?
- Lift increases, drag increases
- Lift increases, drag decreases
- Lift decreases, drag increases
- Lift decreases, drag decreases
Correct

Incorrect
Question 6 of 12

6. Question
When a simple trim tab is set in flight and its associated surface is moved, the tab:
- Position remains constant relative to the control surface
- Will move to a new position and will have to be reset
- Position remains constant relative to the airflow
- Will not move and will have to be reset
Correct

Incorrect
Question 7 of 12

7. Question
During cruise flight with constant power setting, an aircraft shows a permanent tendency to raise the nose. How can this tendency be eliminated?
- By deflecting the elevator trim tab upwards
- By shifting the center of gravity backwards
- By elevator deflection upwards
- By deflecting the elevator trim tab downwards
Correct

Incorrect
Question 8 of 12

8. Question
What is a bendable (ground adjustable) trim tab?
- A fixed tab attached to the rudder or the aileron
- A balance mass at a control surface
- A term for a rudder balance
- A trim device adjustable in flight
Correct

Incorrect
Question 9 of 12

9. Question
What is the task of trim tabs?
- Avoiding permanent control forces
- Reduction of adverse yaw
- Ensuring dynamic stability
- Adjusting bank angle to center of gravity position
Correct

Incorrect
Question 10 of 12

10. Question
The elevator trim tab is deflected upwards. Towards which position will the trim tab indicator have moved?
- Nose-down position
- Neutral position
- Laterally trimmed
- Nose-up position
Correct

Incorrect
Question 11 of 12

11. Question
To remain trimmed in straight and level flight, as speed increases:
- The elevator is deflected further downwards and the trim tab further upwards
- Both the elevator and the trim tab are deflected further downwards
- The elevator and trim tab do not move
- The elevator is deflected further upwards and the trim tab further downwards
Correct

Incorrect
Question 12 of 12

12. Question
Slats are:
- Lift augmentation devices that extend forwards from the leading edge to increase lift at lower airspeeds
- Lift augmentation devices that extend backwards from the trailing edge to increase lift at lower airspeeds
- Lift augmentation devices that extend backwards from the tailing edge to increase both lift and drag
- Lift augmentation devices that extend forwards from the leading edge to increase lift at higher airspeeds
Correct

Incorrect
