AVIT 323 Final Exam Questions And
Answers
What's the difference between an airfoil section and a wings
platform? -
correct answer ✅An airfoil section is a side-view of the wing, amd
the wing's planform is a top down view
What is the difference between mean camber line and the chord
line? -
correct answer ✅Mean camber: Divides an airfoil section in half
between then upper and lower cambers
Chord line: A straight line from the leading edge to the trailing edge

-
correct answer ✅- Good for high speeds
- Leaves the wing surface at low speeds
