A wing has twice the planform area of another wing. Both have the same shape and angle of attack. How do their lift forces compare?

  2. The larger wing lifts half as much
  3. Both wings lift the same
  4. The larger wing lifts twice as much

Correct answer: The larger wing lifts twice as much

Lift varies directly with wing area. A 200 square foot wing lifts twice as much as a 100 square foot wing.
