How do airplanes fly? Let’s find out. There are four forces that impact a plane’s flight: Thrust, Lift, Gravity, and Drag. Planes can fly long and fast when all four of these forces are in balance. Lift is the force that gets the plane in the air; thrust is the force that keeps it moving forward. Drag is the force that slows it down, and gravity is the force that tries to bring it back down to the ground. Thrust and lift are the two forces that keep an airplane flying; drag and gravity are the two forces that work to shorten an airplane’s flight. Thrust - The force that pushes an airplane forward. An airplane’s thrust is a mechanical force generated by its engine or propeller. In a paper airplane, the thrust is generated by someone’s arm throwing it. Lift - The force that pushes an airplane up. An airplane has specially designed wings called airfoils that move the air on the top of the wing faster than the air below the wing, creating higher pressure under the wing. Energy flows from higher to lower energy levels; the difference in pressures above and below the wing causes the upward force called lift. Gravity - The force that pulls an airplane down. Gravity is the force that pulls everything toward the center of the earth. The more massive an object is, the greater the force of gravity. Airplanes that are lighter will need less thrust and lift to go up and stay in the air. Adding weight at the rear of a plane will move the center of gravity aftward. (Note: As youth experiment it is important to know that the addition of paperclips may initially improve flight performance, but with enough paperclips, it will eventually make flight unstable.) Drag - The force that pushes against an object. Airplanes are designed long and skinny, with a pointed nose so that they can move through the air with reduced resistance, or drag. If an airplane had a wider surface it would have to push more air out of the way, requiring more energy, to move forward.

None of these stand out, they’re all so good.
How do airplanes fly? Let’s find out.
There are four forces that impact a plane’s flight: Thrust, Lift, Gravity, and Drag. Planes can fly long and fast
when all four of these forces are in balance. Lift is the force that gets the plane in the air; thrust is the force
that keeps it moving forward. Drag is the force that slows it down, and gravity is the force that tries to bring it
back down to the ground. Thrust and lift are the two forces that keep an airplane flying; drag and gravity are
the two forces that work to shorten an airplane’s flight.
Thrust - The force that pushes an airplane forward.
An airplane’s thrust is a mechanical force generated by its engine or propeller. In a paper airplane, the thrust
is generated by someone’s arm throwing it.
Lift - The force that pushes an airplane up.
An airplane has specially designed wings called airfoils that move the air on the top of the wing faster than the
air below the wing, creating higher pressure under the wing. Energy flows from higher to lower energy levels;
the difference in pressures above and below the wing causes the upward force called lift.
Gravity - The force that pulls an airplane down.
Gravity is the force that pulls everything toward the center of the earth. The more massive an object is, the
greater the force of gravity. Airplanes that are lighter will need less thrust and lift to go up and stay in the air.
Adding weight at the rear of a plane will move the center of gravity aftward. (Note: As youth experiment it is
important to know that the addition of paperclips may initially improve flight performance, but with enough
paperclips, it will eventually make flight unstable.)
Drag - The force that pushes against an object.
Airplanes are designed long and skinny, with a pointed nose so that they can move through the air with
reduced resistance, or drag. If an airplane had a wider surface it would have to push more air out of the way,
requiring more energy, to move forward.
I guess the a340 has become super rare.

What is the time in N.Y now?
Where is Eva based?
Taiwan
Their based in Taiwan, same with China Airlines too
