The amounts depend on the airplane's size, shape, speed,
altitude, and angle of attack, among other things.
Lift, weight, thrust and drag.
There are four forces that act on an airplane that keeps it at a level altitude. Thrust, drag, weight, and lift determine whether a pilot flies at a level altitude.
Lift, Gravity, thrust and drag
Lift equals weight and thrust equals drag.
Lift is equal to drag, so if the drag was 12000N (newtons) the lift would be 12000N. it is mainly used for slowing the aircraft down for decend.
The four forces acting on an airplane in flight are lift, weight (or gravity), thrust, and drag. Lift is generated by the wings and opposes the force of gravity. Thrust is produced by the engines and overcomes the force of drag, which is caused by air resistance.

Thrust, lift, gravity, and drag
Drag is a force that acts opposite to the direction of movement of an airplane. Drag is mainly caused by air. The other forces that act on the plane while moving in the air are thrust, lift etc..
Lift Gravity Thrust Drag Lift is the lifting force that allows airplanes to fly, gravity is the force pulling it back down. Thrust is the force that propels an airplane forward, drag is the aerodynamic friction slowing it down. These variables are constantly interacting with eachother, when an airplane is in straight and level flight, these forces are said to be in balance.
Essentially there are 4 aerodynamic forces that act on an airplane in flight; these are lift, drag, thrust and gravity (or weight).In simple terms, drag is the resistance of air (the backward force), thrust is the power of the airplane's engine (the forward force), lift is the upward force and gravity is the downward force. So for airplanes to fly, the thrust must be greater than the drag and the lift must be greater than the gravity (so as you can see, drag opposes thrust and lift opposes gravity).This is certainly the case when an airplane takes off or climbs. However, when it is in straight and level flight the opposing forces of lift and gravity are balanced. During a descent, gravity exceeds lift and to slow an airplane drag has to overcome thrust.
The 4 forces that let a airplane fly are Lift, Gravity, Thrust, and Drag.
