Each section is interdependent on all the others in forming the whole structure known as an aircraft. Let's look at each section in greater detail. The Fuselage - The fuselage serves as the common attach point for all the other major sections. All baggage is usually stored in the fuselage as well. The number of wings per aircraft can also vary.
Most aircraft seen today are monoplanes, that is they have only one set of wings.
Aircraft that have two sets of wings, like the old barn stormers, are called biplanes. A wing generally has two type of control surfaces on it. They are the ailerons and flaps. Ailerons - Ailerons are what you use to roll the aircraft. As one aileron deflects upward, the other deflects downward, causing the aircraft to roll.
