It doesn't exactly help. What it does do is keep the atmosphere around the planet from dissipating, which is not only necessary for atmospheric flight, but also for breathing and stuff. Atmospheric craft can fly because their wings generate lift as a result of their motion through the air. Without air, no lift. Without gravity, no air.
If a plane is in level flight, gravity (weight) is equal to lift.
Gravity and the skill of the pilot.
The four forces of flight during flight are lift gravity thrust and drag
In a flight, gravity would hinder take off and aid landing. However, because gravity is a vertical force and the x and y components are independent of each other, gravity does not affect speed in the horizontal direction.
The four forces of flight are : Lift, Thrust, Drag, and Gravity. The answer to your question is Lift.
The shape of an airplane's wing is called the airfoil; this helps the plane to fly easily while in flight.
Because the plane has to overcome the force of gravity and it has wings to create lift to make the aircraft fly.
you stear it with the wheel and use gravity and the weight of the plane to help keep it stable in the air . Uhhhh.....go to flight school and learn to be a pilot. They'll teach you how.
Gravity inhibits flight.
You must find the center of gravity by balancing it. Add weight to the front of the plane. This keeps a flight stable.
If the lift generated from the wings is greater than the gravity pulling the plane down, the plain gains altitude and flies
when flight moves the velocity of air above and below the plane is different ..this gives it an upward thrust (according to bernauli's theorem).
