c)
C. Spring tabs increase drag, while trim tabs decrease drag
d)
D. Spring tabs are used only during takeoff
11.
What does active load control in an aircraft aim to achieve?

12.
What happens to wing stress during a roll maneuver?
a)
A. Stress decreases
b)
B. Stress remains the same
c)
C. Stress increases as the g-load increases with bank angle
d)
D. Stress only affects the fuselage
13.
What is a common approach to counter dynamic loads on an aircraft?
a)
A. Increasing engine power
b)
B. Strengthening the wing structure
c)

d)
D. Using decorative elements
14.
What is the Roll Maneuver Load Alleviation (RMLA) system?
a)
A. A system that increases drag during rolls
b)
B. A system that varies control surface deflections to alleviate roll-induced loads
c)
C. A system that enhances passenger comfort during rolls
d)
D. A system that reduces engine power during rolls
15.
How does the RMLA system help during rolls?
a)
A. By using only the outboard ailerons
b)
B. By moderating or eliminating the deflection of the outboard aileron and relying on the inboard ailerons
c)
C. By increasing the deflection of the trailing edge flaps
d)
D. By using the rudder more extensively
