Question

Changing the camber of a wing by designing positive curvature in or lowering trailing edge flaps allows:______.

A. Higher Maximum Coefficients of Lift
B. Maximum Coefficient of Lift at lower Angle of Attack
C. Lower landing/approach angles of attack
D. A and C
E. All of the above

Answer 1

E. All of the above

Explanation:

The wings that contain curvature is known as "camber," which in essence is half of a venturi, generating a greater-pressure area at the bottom of the wing, and a lesser-pressure area at the top. Creating an extra lift, the camber (curvature) of the wing is increased by extending (in an arc) the leading edge, typically by forcing or hinging the leading edge out on tracks.

The additional camber provides them with the additional lift needed for safe operation and control at slower aircraft speeds, such as when departing or landing.

By allowing wings to operate at a greater angle. A high lift coefficient is established and used as an angle of element for both attack and speed, when an airplane can travel extra steadily or take off and land in a smaller time with slats

Therefore the correct option is E.
