Since the dawn of man, it has been the dream of man to soar above the clouds as birds. Then the airplane was invented. What is it that makes a huge mass of metal that weighs so much, fly? How is it that a person pilots such an ingenious invention? Flying is an art that requires much dedication and perseverance to get through the training. The requirement to get a license is much more difficult than a driver’s license. This is going to help you get an idea of how an airplane is flow and what makes it fly. Every airplane has the same main parts. The only difference between a Cessna 172 Skyhawk and a Boeing 747 is the size. The main parts of a Skyhawk consist of a fuselage, propeller, engine, wings, landing gear, and the tail. Each and every part has a specific duty to make the huge mass of metal fly. All the parts do certain things such as creating lift, pitching it up or down or even making it bank left or right. Every part contributes to the ingenious invention that allows humans to fly. The fuselage is the body of the aircraft. Everything on the aircraft has some sort of relation to the fuselage. The fuselage contains the cabin of the airplane that holds passengers and pilots. Also in the cabin is the baggage compartment. The baggage compartment is located behind the passengers and is accessible from the outside of the plane through a compartment door but is also reachable over the passengers’ back of the bench seat. The pilots have two individual seats while the passengers have a bench seat. In front of the pilots are the controls. There are two sets of rudder pedals and yokes for each pilot, just in case something happens or the other pilot just wants a break. One of the most important parts of the airplane is the propeller. Obviously without a propeller the airplane would not be able to fly. There are many varieties of propellers, some of which you can control the pitch of the blade. However, on a Skyhawk it is fix-

pitched. Unlike a car which has a transmission that allows the engine to keep running while the car stays stopped the airplane has a direct drive. A direct drive is where the engine connects directly to the propeller by a drive shaft. So, when the engine is running the propeller is turning. Now the engine, the engine is a basic engine with cylinders, carburetors, pistons and so on. The difference is how it is controlled. In an airplane you are given three engine controls; the throttle, mixture control and the ignition. The ignition is just like a car only with a couple of changes. The ignition has five positions. The positions are OFF, R, L, BOTH, and START (“Cleared” 1-22). The R and L positions let you test the magnetos or ignition systems while the engine is running before takeoff. The starter position will allow you to start the engine which is past the both position. The both position is used while in normal flight. After the engine is started and the key is released it automatically goes to the BOTH position (“Your First”). The throttle controls the power of the engine simply with a lever on the pilot
