The main parts of a plane

Rudder:	On an aircraft the rudder is used to help turn the plane. In basic form, a rudder is a flat plane or sheet of material attached with hinges to the craft's stern, tail, or after end.
Drag:	Drag is the aerodynamic force that opposes an aircraft's motion through the air. Aerodynamic means: having a shape which reduces the drag from air moving past.
Lift:	Lift In order for a plane to fly, it must generate lift to oppose its weight. For a plane to get lift I must move through the air.
Wings:	A plane's engines are designed to move it forward at high speed. That makes the air flow rapidly over the wings, which throw the air down towards the ground,  for the plane to generate an upward force called lift that overcomes the plane's weight and holds it in the sky. The wings force the air downward and that pushes the plane upward.
Balance:	When the plane flies horizontally at a slow speed, lift from the wings exactly balances the plane's weight, and the thrust exactly balances the drag. This creates a lift force, greater than the plane's weight, which powers the plane higher into the sky.
