how are airplanes like birds.?

Answer 1

hum...they fly?
they are aerodynamic?
They do not lay eggs, that is for sure.

Answer 2

Airplanes are really not at all like birds: they fly for completely different reasons. Birds develop lift by forcefully changing the shape of their wings, while airplanes use thrust to develop forward motion, which in turn allows their rigid wings to develop lift by means of the Bernoulli effect.

Birds don't have wheels because they can develop lift from a standing start. Also, the shape and the control methods are very different. At first glance, some airplanes superficially resemble birds. But take a closer look. Airplanes are rigid; birds are flexible shape-shifters. That really tells the whole story.

And, I am sorry to say, pilots don't have to have anything like perfect vision. An airline pilot just has to have eyesight correctable to 20/30 in one eye, and no cataracts or detectable glaucoma.

For lots more information, do an internet search on "aerodynamics."

Answer 3

Birds are considered nature's perfect flying machines. Every part of a bird is adapted to flying. Their bodies are as streamlined as an airplane, enabling them to slip easily through the air. The bird's wings, with each of its feathers, are shaped much like an aircraft's wing - curved on top and flatter underneath. This allows both wings to achieve lift in the same way.

Answer 4

Good question - if we look closely we can see lots of similarities.

They both:
1. Use wings to generate lift
2. Use a tail for steering and stability
3. Are aerodynamically shaped - pointy at the front, widen smoothly into a tubular body, tapered rear
4. Have no external ears, a smooth surface with a minimum of protuberances into the airstream
5. Have retractable landing-gear
6. Have eyes at the front
7. Take-off and land into the wind
8. Navigate using the earth's magnetic field

Answer 5

airplanes like birds take off into the wind.

Answer 6

Airplanes have been engineered to mimic the aviation capability of birds but the major similarity is the shape of their wings, the steamlined body and their tails.

Answer 7

Pilots need to have perfect vision just like birds.
And the obvious: airplanes have wings and fly.

Answer 8

they have wings and they fly and technichally for the ones that drop fertilizer on farmland are laying eggs

Answer 9

Both of them have wings

Answer 10

They have things called WINGS... and they both FLY too...

Answer 11

most of the machines around us are derived from animals and nature.

We are just copycats.
