Sadly, this is a much more complex question than it appears to be and the answers are still being debated by scientists. Howver, the simplest explanation is that the motion of the air around the wing creates greater pressure on the lower surface of the wing and this greater pressure lifts the plane.
Howver there is a significant controversy over exactly how this occurs.

Basically = The way that and airplanes wings are shaped when there is air moving over them (like when the plane moves forward) the wings force air downwards, and the forces the plane upwards.


Advanced = The shape of the planes wings creates a difference in air pressure... it creates a high pressure area under the wing (where the air gets compressed together) and a low pressure area above the wing (the air gets spread thinner. This difference in pressure creates different forces on the wing (think how a vacuum cleaner exerts force... there is a low pressure area inside the tube and it sucks things in to equalize pressure). You would think that the high pressure below the wing would push the plane upwards, but differences in pressure can only create suction(or pull forces) and not push forces. So what happens is that the low pressure area above the wing tries to normalize, and exerts a pulling force on the wings, effectively SUCKING the plane higher into the sky.

Hope this helps :)

The basic concept is the Bernouli Principal. It says that a fluid (in this case air is considered a fluid) traveling a greater distance must travel at a faster rate to travel the same distance in the same time. The shape of a wing is flat on the bottom and curved on top. This curve forces the air traveling over the top of the wing to travel a greater distance, and thus produces an area of lower pressure on the top of the wing, which provides lift. Thrust is also a factor- the faster you go the more air travels over the wing, and the more lift you create.

It al started with lift. Lift and drag are mechanical forces generated on the surface of an object as it interacts with a fluid. The net fluid force is generated by the pressure acting over the entire surface of a closed body. The pressure varies around a body in a moving fluid because it is related to the fluid momentum (mass times velocity). The velocity varies around the body because of the flow deflection described above. If this is confusing to you I added the site I found it from.

Two necessities for all fixed-wing aircraft (as well as rotary-wing aircraft) are air flow over the wings for lifting of the aircraft, and an open area for landing. The majority of aircraft, however, also need an airport with the infrastructure to receive maintenance, restocking, refueling and for the loading and unloading of crew, cargo and/or passengers. While the vast majority of aircraft land and take off on land, some are capable of take off and landing on ice, snow and calm water.

The wing (or the chord line in a wing to be extra particular) makes a definite perspective with the relative wind. the attitude is talked approximately as the "perspective of attack". At particular angles the relative wind has a laminar flow over the wings of the plane. in accordance to Bernoulli's theory which in certainty states that as quickly as the particle is accelarating, it imposes lesser tension. consequently the coolest of the wing has a curvature and the backside is extremely flat. meaning, the wind accelarating on good of the wind has lesser tension than the wind on the backside. that's given in laminar flow that the wind has to return and forth the width of the wing in the comparable time. and as the coolest of the wing has a bigger section than the backside area, the wind has to return and forth quicker. for this reason impossing lesser tension while in comparison with the backside, for this reason you have raise. additionally on your guidance, there are 4 forces on the plane for the time of flight. raise, Weight, Drag, and Thrust. while raise is extra suitable than weight and thrust is extra suitable than drag. you have a advantageous secure flight abode!!! :)

the wings are on a slight tilt,and air from the motors is forced under them causing lift,there are ailerons and flaps on the wings that change the tilt of the wing causing it to either go up or down,
