How does thehow is a birds flight and airplanes flight alike and different?

Answer 1

The airplane and bird both generate lift by the air flowing over their wings. The shape of the wings cause a low pressure zone above the wing and a high pressure zone under the wing generating lift. The main difference is the airplane's wings are stationary requiring engines to supply the forward motion to generate the airflow/lift needed. A bird has to flap their wings to generate the forward motion/lift. A bird can cause lift by flapping it's wing up/down but also by changing the angle of it's wings (angle of attack) to generate lift. The bird can generate more forward thrust by also drawing the wings rearward, Different birds fly differently (hummingbirds vs. condors, etc).
