To put it quite simply Suction. The wing of an air plane is made in such a shape that as it slices through the air, it takes longer for the air at the top of the wing to rejoin the air that has passed along the bottom of the wing. in effect this brings about a situation where a partial vacuum happens on the top of the wing which in turn causes the wing to be sucked upwards. combine this with enough forward speed and a lot of other engineering and you have flight.

What does the weight of the airplane have to do with the lift of it?
The weight of an aircraft counteracts the lift produced by an aircraft. The heavier an aircraft weighs the greater the lift needed to get off the ground.
How do wingless aircraft produce lift?
The only 'wingless aircraft' are helicopters. These produce lift lift from the rotor blades, which are in fact, long narrow wings.
What is the lift force in an aircraft?
The lift force is the force acting against the aircraft's weight. For straight and level flight, lift acts in the upward vertical direction and the weight of the aircraft acts in the downward vertical direction. For level flight, lift = weight.
Is lift an unbalanced force?
Yes, lift is an unbalanced force. It acts in opposition to the weight of an aircraft, allowing it to rise or remain in the air. When the lift generated by the wings exceeds the gravitational force acting on the aircraft, the result is an upward acceleration. Conversely, if lift is less than weight, the aircraft will descend.
What is a rotary aircraft?
A rotory aircraft is essentially a helicopter or a type of aircraft that relies on the movement of its wing to produce lift.
If an aircraft is flying horizontally then its weight must be balanced by what force?
Lift balances weight. Thrust balances drag.
What is aircraft propeller and what function does it do to the aircraft?
An aircraft propeller is what gives the aircraft power to move it forward (or backward, depending on it's pitch). This enables the aircraft to acquire lift and gain altitude. Propellers are found on some fixed-wing aircraft and autogyros. On helicopters, the blades that lift it and stabilize it are called rotors.
Why is maximizing the ratio of lift to drag forces desirable?
Maximizing the lift-to-drag ratio is desirable because it allows an aircraft to generate more lift for a given amount of drag, resulting in improved fuel efficiency and range. A higher lift-to-drag ratio also means the aircraft can fly at higher altitudes and speeds, which can be beneficial for performance and overall aircraft capabilities.
What is the term for the upward force on the wings of an aircraft?
Lift.
What part of aircraft makes flight to take off?
The engines provide forward thrust, allowing the wings to generate lift. It is the lift that allows the aircraft to take off.
How in fighter aircraft is instant pressure difference created for lift?
Flaps are used on aircraft to increase the wing area of the plane and therefore increase lift and reduce speed.
What force pulls an aircraft toward the ground acts against the force of lift in level flight?
Gravity is the force that pulls an aircraft towards the ground, acting against the force of lift generated by the wings in level flight. Gravity pulls the aircraft downward, while lift generated by the wings counteracts this force to keep the aircraft aloft.
