Why do airplanes not fall?
Air moves more slowly across the bottom of the wing. Slower moving air pushes harder on the wing than faster moving air. So, the air under the wing pushes the plane up. That is how planes stay up in the sky.
Can planes stay in one place?
Techincally, there is only one way for the aircraft to remain hanging motionless in the air: if weight and lift cancel each other out perfectly, and at the same time thrust and drag cancel each other out too. But this is incredibly rare. To stay in the air and sustain its flight, an aircraft needs to be moving forward.
Why do airplanes turn when they fly?
Airplanes turn because they are generating lift in a direction that is not pointing up and down…. So when the pilot turns the flight control it moves the ailerons on the wings, one up and one down. The aileron pointing down causes more lift to be generated by that wing and the aileron pointing up generates less lift.
What happens when an airplane stalls while flying?
The airplane tilts forward and passes into the fall. When the plane is flying in curves, the stall can also occur only on one wing. The airplane then starts to spin and falls down like a stone. Only at very high altitudes can experienced pilots succeed in regaining control over such a falling plane.
What causes a plane’s wings to lift?
The lift is caused by the special shape of the wings. The wing deflects the air downwards and thus generates its own lift upwards. This works well as long as the air flows cleanly to the rear at the surface of the wing.
Why does the pilot push down the nose of the airplane?
He needs to push down the nose of the airplane to reduce the angle of attack. In this way he avoids the vortices and can ensure lift. If he does not do this and the aircraft gets steeper and steeper in the air, a dangerous stall occurs, starting roughly at an angle of attack of 18-20 degrees.
