Because air drag and flow is what gives the wings lift. Air travels faster under the wing and slower over top the wing. This creates less pressure on the top of the wing providing 'lift'.

What are the 4 forces on an aircraft?
The 4 main forces of flight are: drag, thrust, lift and weight
Why kites ascend in flight?
In an air flow the pressure above the kite is lower and the pressure under the kite is greater; as a result the kite ascend to lower pressures.
What is the Uses of computer in airport?
* To maintain access control. * Record of flights arrival and departure. * Maintain record of paseenger list * Staff details * Flights details * Control of passenger * Account maintainence * graphic representation of the load plan for an aircraft * load control activities necessary for a given flight. * load sheethttp://ezdia.com
Why is it necessary to derate cables when installed in a duct?
Heat cannot escape the duct as easily as in open air. This results in the same amount of current causing the cable to heat to a higher temperature.
What are the disadvantages of air traffic control systems?
constant stress, tests, medical boards, a lot of necessary information, a lot of documents, the time limit, there is no room for error, simulators, test, certificate renewal controller, is it enough?
What forces act on aeroplane when taking off?
The weight of the aeroplane and its cargo, friction where the plane's wheels meet the runway, the lift provided by the motion of the air around the aerofoil shape of the wings, aerodynamic drag,
What is drag in the properties of flight?
The resistance caused by the aircraft moving through air
What do you call a person who take care of passengersin an aeroplane?
They are called flight attendants (also cabin crew, stewards/stewardesses, air hosts/hostesses and cabin attendants)
What is the shape of an airplane and why does this have this shape?
The commonly used fuselage shape allows the aeroplane to move forward through the air at a reduced drag. And the sectional shape of the wings create lift.
What are the 4 forces for air and flight?
Thrust (forward) Drag (backwards)Lift (up) Weight (down)
What are the forces involved in airplane flight?
Thrust and drag are two important forces act on air craft.
What is aeroplane means?
Aeroplane means a vehicle with wings which flies through the air.
How do you alter drag in flying devices?
Drag is comes from the resistance created by objects to the flow of a medium. In this case the drag of an aircraft can be increased by better aerodynamics and flight surfaces. Drag can be increasing surfaces that impede the smooth flow of air.
What does 'aeroplanes are often pressurised'mean?
this means that the air outside the aeroplane is too thin for us to breathe and the air has to be pressurised in the aeroplane. that is why the aeroplane has masks above your seat so if the air becomes to thin the air coming through the mask is the right for you to breathe.
What is the force the keeps the plane in the air?
The four forces of flight are : Lift, Thrust, Drag, and Gravity. The answer to your question is Lift.
What is filled in the tire of aeroplane?
air
Why do aeroplane fly at flight level?
The higher you go the thinner the air is, and less resistance is offered by it. Thus, airplanes fly at high altitudes because the fuel consumption is lower.
