Why does an airplane bend at the turns Why can't it just turn keeping the airplane straight?

Answer 1

If it didnt bank over when the plane turns, it would slide straight ahead in the air. What makes the plane turn is the elevator rudder. First the pilots bank the plane over to one side, (the which they intend to turn), and the use the elevator rudder.

If they only used the aileron (i think its called, the rudder at the back of the fuselage standing vertical), the plane would not turn but simply fly ahead, but not have its nose pointing directly where its going. It would be about 5-15 degrees off.

A: You actually can turn an airplane with no bank whatsoever. By applying reverse aileron to the turn and applying rudder pressure you can make a very easy turn in either direction. This is a simple method used to make people within the plane sick. The feeling of sliding out of control is very much part of this terrible feeling during a turn like this. The reason we bank a plane in a turn is to maintain a center of gravity that is comfortable and controllable in the plane. Turns of this nature may be done during landing to maintain altitude and control to align with the runway during windy days. While uncomfortable, it is sometimes a needed movement.
