How does Bernoulli's principle explain how planes lift into the air?

Pressure is inversely Proportional to the Velocity of a Fluid over a surface. This a Corollary of Bernoulli's Principle.
A Wing is designed so that the BOTTOM side has a Shorter Distance from Leading Edge to Trailing Edge than the TOP side. Therefore the AIR flow over the TOP has a LOWER Pressure than the AIR Flow over the BOTTOM side.
Therefore the WING is being PUSHED UP by the greater Force on the UNDERSIDE. This is called LIFT.

What Principle explains the operation of a hydraulic lift system?
Pascals
What creates lift on an airplane?
Bernoullis principle says that as a liquid's flow rate increases the pressure of the fluid decreases (think of your thumb on a garden hose) When air ( fluid) flows over a wingsurface the shape of the wing directs the air to travel a greater distance, and its speed is decreased. The pressure difference below the wing (higher) relative to the pressure above the wing (lower pressure) creates lift as high pressure areas move to low pressure areas in an attempt to restore equilibrium
How do planes stay up?
Lift pushes the airplane up. The way air moves around the wings gives the airplane lift. The shape of the wings helps with lift, too.
What is an airfoil?
an object shaped to produce lift by the bernoulli principle when moving in a fluid
Explain how a hydraulic lift operates?
scrat fish
What is the invention of bernoulli?
he found the principle for the birds lift which benefited people to discover the air planes.
How do planes glide?
The same way it flies... Gliders are lighter and they use Bernoulli's principle for lift. and once they get speed they can keep flying... they also use updrafts from the ground to get lift
How does an airplane get lift during take off?
As the airplane speeds up the air flowing around the control surfaces speeds up as well. When this happens the horizontal stabilizer is deflected into the wind causing the nose of the aircraft to rise. As the nose rises the angle of the wings also increases and create lift by 'air deflection' and 'bernoullis principle'. Many other factors are involved to create lift, these are just the main principles.
What is the force that enables planes to stay in the air?
Lift
Why so planes fly?
Because you idiot the planes wings have lift and the motor's have the lifting power to enable the wing's lift to actually work it is honestly a chain reaction....
Why do planes have wings?
To provide the lift that is required to glide through the air without plummeting to the ground.
How do jet planes fly?
Jet planes fly with the help of Thrust and Lift produced by the jet engines.
Who explained the operation of a hydraulic lift system?
Bernoulli's principle. The above answer is wrong. Its Pascal's Principle :)
Do planes get more lift in hot weather?
No, when the weather is hot the air is less dense so they will get less lift.
What is the fucntion of planes fins?
to "slice" through the air and create lift.
How do you lift heavy objects efficiently?
By using the principle of levers.
