✈️ How Planes Fly

What you’ll learn

1. Wings and LiftUnderstand that a wing's curved shape and fast-moving air create an upward push called lift.A plane's wing is curved on top and flatter underneath. When the plane rushes forward, air presses harder under the wing than on top, creating an upward push called lift. Wings only make lift when air rushes past them fast, which is why planes race down a long runway before taking off. Lift is what holds a plane in the sky.
2. Engines and the CockpitLearn how engines make thrust and what the pilots do in the cockpit.Big planes have jet engines that suck in air, burn fuel, and blast it out the back to push the plane forward with a force called thrust. Smaller planes use propellers. At the front is the cockpit, where usually two pilots sit surrounded by screens, dials, and controls to fly the plane and talk to helpers on the ground.
3. Takeoff to LandingFollow a plane's journey from takeoff, through cruising, to a safe landing.A plane races down the runway until it is fast enough, then the pilot tilts the nose up and the wings lift it into the sky. It cruises high above the clouds for hours. To land, the pilots slow down, lower the landing gear, and use wing flaps to fly slowly, gently bringing the wheels down onto the runway for a soft, safe landing.
4. Plane SpottingRecognize different kinds of planes, from jumbo jets to small propeller planes.Planes come in many sizes. Jumbo jets like the Boeing 747 and the two-floor Airbus A380 are giants that carry hundreds of people using four huge engines. Smaller propeller planes buzz and hum and are used for short trips, fun, and helping people. Every plane in the sky flies using the same ideas: lift, thrust, and clever wings.
