Why do plane wings go up when landing?

When the airplane is taking off, the flaps help to produce more lift. Conversely, flaps allow for a steep but controllable angle during landing. During both, efficient use of flaps help to shorten the amount of runway length needed for takeoff and landing.

Pointing the nose up causes a high angle of attack. This creates high lift at low speed and high drag. The aim at landing is to touch down at a low speed. The drag helps to slow the plane down.

The idea is to get as much altitude as possible, as close to the airport as possible. So you have a relatively steep initial climb, followed by a reduction of climb angle to cruise climb and a power reduction.

The nose wheel tiller is used until approximately 80 knots to keep the aircraft straight during takeoff, thereafter the rudder is used. During landing, the rudder is used until the aircraft is slowed to 80 knots, then the tiller is used once again.

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.

In general airliners cannot do sustained inverted flight as they lack a fuel system (and lubrication system) for sustained inverted flight. A barrel roll is readily executable. Youtube has a video of Tex Johnston doing a barrel roll.

Well it depends on the plane, but most planes can't fly without their wing, and basically they would spiral down into the ground. Many modern jet fighters have a lifting body and they can fly without a wing because the body provides a lot of the lift.

The most used is the Instrument Landing System or ILS. The ILS consists of two radio beams which project up from the area around the runway up into the approach path. These signals are then picked up in the aircraft by the ILS receiver which displays them on the screens in the flight deck.

Landing. While landing, speed is largely affected by the aircrafts current weight, commercial airplanes typically land between 130 and 160 mph (112 to 156 knots).
