Changing the camber of a wing by designing positive curvature in or lowering trailing edge flaps allows Group of answer choices A) higher maximum coefficients of lift. B) maximum coefficient of lift at a lower angle of attack. C) lower landing/approach angles of attack. both A and C above all of the above

A,B.C are correct.

Explanation:

The given question can be explained as following-:

The wings have a curvature on them called 'camber', which in essence is half of a venturi create a high pressure area on the bottom of the wing, and a low pressure area on top of the wing. To generate additional lift, the wing's camber (curvature) is increased by extending (in an arc) the leading edge, which is typically done by forcing the leading edge out on tracks, or hinging them out.

The additional camber gives them the additional lift needed for safe operation and control at slower aircraft speeds as when taking off or landing.

Allow the wing to operate at a higher angle of attack. A higher coefficient of lift is produced as a product of angle of attack and speed, so by deploying slats an aircraft can fly more slowly or take off and land in a shorter distance

Therefore, all A,B,C options are correct.
