Is the force of prepultion and the force of gravity on an airplane an action and reaction force pair?

Contrary to common usage, gravity is not a force. It is a change in the dynamics of space, so in a gravitational field you are moving but feel like you are standing still. Actually you ARE "standing still" (relativistically speaking) while you are falling in a gravitational field; there is no force acting on you.
Propulsion is the work it takes to fight against the falling component of gravity, just like the pressure of the earth on your feet is doing the work of keeping you from falling toward the center of the earth.
The action-reaction component involves heating the air and the earth by pushing your propellant molecules earthward to maintain your altitude. Similarly, the earth heats up beneath your feet as the packed molecules of the earth fight against the natural tendency to collapse into the center.
Here is a question: If everybody in the Western Hemisphere jumped up and landed at the same time, would the earth shift twice? (Once for taking off and once for landing?) The answer is Yes, but while we were in the air, we would cause a shift in the other direction by attracting the earth toward us! The final effect would be zero, because the center of gravity (of us and the earth together) would not have changed.

What is the nickname of Newton's third law?
"Action and reaction", or "For every action there is a reaction"."Action and reaction", or "For every action there is a reaction"."Action and reaction", or "For every action there is a reaction"."Action and reaction", or "For every action there is a reaction".
What is the action and reaction when earth gravity pulls down on a book?
gravity i guess. i do not understand your question sorry -this is not the answer i just guessed.-
What is the action and reaction of earth gravity pulls down on you?
The Earth pulls down on you, but you pull up on the Earth!
Why do airplanes fly according to newtons third law?
Newton's third law states that every action has an equal and opposite reaction. In an airplane the action is the engine pushing the air behind it. The reaction is the plane moving forward. Also the airplane wings are angled so that air is pushed down making the air push the plane upward.
How does the law of gravity affect objects?
For every action there is a equal and opposite reaction... aka newtons 3rd law of motion. hoped that helped :)
In atmosphere why there is no reaction of any action?
Forces ALWAYS come in pairs - as in "action/reaction". The atmosphere is no exception. For example, if the air pushes an airplane up, then the airplane also pushes the air down.
What is the reaction force if Sun's gravity pulling on Earth is the action force?
Earth's gravity pulling on the Sun.

How do airplanes defy gravity?
They don't actually defy gravity. Rather, an airplane uses its wings to 'glide' amongst the air currents. It's a matter of Action=-Reaction. Because of the shape of the wings, most of the air will move under the wings, which causes the air density to heighten and the airplane will be pushed upwards. An airplane can rotate its wings, so it can choose whether or not it wants to go upwards or downwards. Apologies for my bad English, it's not my first language.
How do you move when there is no gravity?
Very freely; Newton's law of action and reaction comes into full play.
Two forces of Newton's Third Law are what?
Newton's third law of motion is every action has and equal and opposite reaction.
How does action reaction force apply to dance?
Because it scientificallty proves that the force of gravity will knock you over
What is the action and reaction of earth gravity pulls down on you?
The Earth pulls down on you, but you pull up on the Earth!
What was newtons main contribution to enlightenment thought?
Issac Newton's contribution was Law of Gravity, Action/Reaction and Calculus

Is airplane an action verb?
Airplane is a noun
