4.
What is the primary function of plain flaps?
a)
A. To increase lift and decrease drag
b)
B. To increase lift and drag
c)
C. To decrease lift and increase drag
d)
D. To decrease lift and drag
5.
How do split flaps differ from plain flaps?
a)
A. Split flaps increase lift and decrease drag
b)
B. Split flaps increase drag significantly, helping to slow down the plane
c)
C. Split flaps decrease lift and drag
d)
D. Split flaps decrease both lift and drag
6.
What is unique about slotted flaps?
a)
A. They do not affect lift
b)
B. They have a gap that allows air to flow through, increasing lift more efficiently
c)
C. They increase drag more than lift
d)
D. They are only used during emergencies
7.
How do Fowler flaps enhance lift?
a)
A. By sliding backward and downward, making the wings bigger
b)
B. By increasing drag significantly
c)
C. By creating a gap for airflow
d)
D. By remaining fixed in place
8.
What are leading edge flaps?
a)
A. Fixed extensions on the wings
b)
B. Airfoils extended from and retracted into the leading edge of the wing
c)
C. Control surfaces for lateral control
d)
D. Decorative elements on the wings
9.
What is the difference between a slat and a slot?
a)
A. A slat is a gap, while a slot is a movable device
b)
B. A slat is a movable device, while a slot is a gap or passage for airflow
c)
C. A slat increases drag, while a slot decreases drag
d)
D. A slat is used for decoration, while a slot improves fuel efficiency
10.
How do flaps and slats enhance low-speed performance and lift production?
a)
A. By making the wing's profile larger and more curved
b)
B. By reducing the aircraft's weight
c)
C. By increasing the aircraft's speed
d)
D. By reducing the wing's surface area
11.
What are ground spoilers used for?
a)
A. To assist in lateral control during flight
b)
B. To increase lift during takeoff
c)
C. To assist in braking action after the aircraft lands
d)
D. To reduce fuel consumption during flight
12.
When are flight spoilers typically extended?
a)
A. Only on the ground
b)
B. During lateral control when the aileron on the same wing is deflected upward
c)
C. Only during emergencies
d)
D. To enhance passenger comfort
13.
What happens when spoiler panels are actuated as speed brakes?
a)
A. Only one wing's spoiler panels raise up
b)
B. Both wings' spoiler panels raise up
c)
C. The flaps are fully extended
d)
D. The aircraft's speed increases
14.
Where might in-flight spoilers be located besides the wings?
a)
A. Only on the wings
b)
B. Along the sides, underneath the fuselage, or back at the tail
c)
C. Inside the cockpit
d)
D. On the landing gear
15.
What effect do leading edge flaps have on the wing's profile?
a)
A. They make the wing's profile smaller and less curved
b)
B. They have no effect on the wing's profile
c)
C. They create a larger, more curved wing profile
d)
D. They decrease the wing's surface area
16.
What is the main function of slotted flaps?
a)
A. To increase lift by allowing airflow through a gap
b)
B. To decrease drag
c)
C. To reduce the aircraft's speed during cruise
