Why do planes twist wings when landing?

Often, the purpose of lift redistribution is to ensure that the wing tip is the last part of the wing surface to stall, for example when executing a roll or steep climb; it involves twisting the wingtip a small amount downwards in relation to the rest of the wing.

Wing flaps are a significant part of the takeoff and landing process. When the airplane is taking off, the flaps help to produce more lift. Conversely, flaps allow for a steep but controllable angle during landing.

This prevents both flailing of the arms in the crash sequence and protects the head from flying debris. The head should be as far below the top of the seats as possible to prevent injury from any collapsing overhead compartments.

Wake turbulence can cause a plane to vibrate The bigger the plane, the greater the wake. Like crosswinds, pockets of unstable air can force the pilot to react to keep the plane stable. These sudden movements cause the plane's wings to flex again, creating vibrations throughout the aircraft.

Short answer: Because planes are larger than birds. Flying by flapping their wings works very well for birds and insects. Machines that fly this way, known as ornithopters, have been built, some large enough to carry a man. But larger than that and the laws of physics become a serious problem.

From a practical point, no, a modern airliner will not lose a wing due to turbulence. Modern airlines are very tough and designed to withstand extreme turbulence. In theory, it might be possible. But to my knowledge, it has not happened to any jet airliner.

The best seat on the plane to avoid turbulence is either over the wings or towards the front of the aircraft. The wings of the plane keep it balanced and smooth, whereas the tail of the aircraft can bounce up and down more. The closer a passenger is to the front of the plane the less turbulence they would usually feel.
