At least every two years a pilot must pass a Third Class Medical exam to make sure that they are physically capable of flying an airplane. The pilot is responsible for the safety of the airplane and makes the final decision on whether the airplane is safe to fly. Before getting into the airplane, the pilot performs a walk around inspection of the plane. During this inspection the pilot visually checks the fuel tanks, the oil level, the movement of the ailerons, the elevators, the rudder, the landing gear and the exterior skin of the aircraft. After completing the walk around inspection the pilot climbs into the cockpit and after starting the airplane completes an instrument check list to ensure that the plane is safe and ready to fly.
Airplanes takeoff and land at airports.
This special shape creates lift. As the airplane moves forward air passing over the top of the top of the wing moves faster than the air flowing beneath, resulting in lower pressure area above the wing. The pressure difference provides the upward force called lift. Thrust is created by the turning motion of the propeller. Like the wing, a propeller is also an airfoil.
