Summarize this article in one sentence.
If you are at a controlled airport you must contact Ground Control before taxiing. They will give you further information as well as a transponder code, commonly called a "squawk code." Be sure to write this down, as this information must be repeated to Ground Control before you are given clearance for takeoff. Once given clearance, proceed to the runway as directed by Ground Control, making sure to never cross any runway unless you are cleared to do so. Usually 10 degrees of flaps are used to help increase lift. Check your aircraft manual, though. - Some aircraft do not use flaps for takeoff. Before you reach the runway, stop at the run-up area. You'll have to perform the engine run-up procedure here. This helps insure that your aircraft is ready to fly safely. Ask your instructor to show you this procedure. After completing a successful run-up, notify the tower and wait to be cleared to continue to and/or enter the runway. Push the fuel mixture knob completely in and advance the throttle slowly. This will increase the engine RPMs (revolutions per minute), generating thrust and the airplane will start to move. Note, though, that the plane will want to go left when you do this, so add proper rudder to stay on the runway centerline. If there's a crosswind, you will need to turn the yoke, carefully, into the wind. As you pick up speed, slowly decrease this correction. You'll need to control the yaw (twisting on a vertical axis) with the rudder pedals. If the plane starts doing twisting, use the foot pedals to control it. In order to take off into the air, the plane needs to achieve a certain speed to create enough lift. The throttle should be full on in most aircraft, though some will have a maximum setting to reduce over torquing. You will gradually build enough airspeed to become airborne (usually around 60 knots for small planes). The airspeed indicator will tell you when you have reached this speed. When the plane gets enough lift, you'll notice the nose lifting off the ground a bit. Pull gently back on the flight control, being sure to maintain the proper climb rate for the particular aircraft. This will cause the whole airplane to leave the runway and rise into the air. Remember to maintain climb speed and apply proper rudder. When at a safe height above the ground and you have a positive rate of climb as indicated by the VSI (Vertical Speed Indicator), return the flaps and landing gear to neutral position. This will reduce drag and extend the safe flying time and distance.
Get permission to take off. Adjust the flaps to the proper angle for takeoff. Perform an aircraft run-up procedure. Notify the tower that you're ready for takeoff. Start the take-off run. Get up to speed. Pull back on the yoke at this point.
