Deploying a Fowler flap will:

• A. Move forward, then down.
• B. Move aft, then turn down.
• C. Move straight down.
• D. Move up, then back.

Answer: (B)

Fowler flaps increase lift by increasing the wing area and camber. When deployed, they first slide backward along tracks, extending toward the trailing edge to add wing surface. As deployment continues, they are deflected downward to increase camber and lift even more. So the sequence is to move aft, then turn down. The other motions don’t match how Fowler flaps function: moving forward would reduce lift by shrinking effective wing area; moving straight down doesn’t add area; moving up and back isn’t how this flap is designed to operate.
