Question: How can planes fly?

How do planes fly simple explanation?

A plane’s engines are designed to move it forward at high speed. That makes air flow rapidly over the wings, which throw the air down toward the ground, generating an upward force called lift that overcomes the plane’s weight and holds it in the sky. The wings force the air downward and that pushes the plane upward.

Do planes really fly themselves?

Contrary to what people are led to believe, flying remains very hands-on operation, with tremendous amounts of input from the crew. Our hands might not be steering the airplane directly, as would have been the case in the 1930s, but almost everything the airplane does is commanded, one way or the other, by the pilots.

Why do planes stay in the air?

Airplanes fly because the air pressure hits against the wind. Airplanes stay in the air by the air pushing the wings. Airplanes stay in the sky because the wind goes up and travels through the wing to keep the plane in flight.

How Can planes fly upside down?

To fly upside down, a stunt plane just tilts its wings in the right direction. The way a wing is tilted is the main thing that makes a plane fly, and not the wing’s shape. The angle of attack is the angle between the axis of the wing and the direction of incoming air. Public Domain Image, source: Christopher S.

What are 3 things needed for flight?

The four forces are lift, thrust, drag, and weight. As a Frisbee flies through the air, lift holds it up. You gave the Frisbee thrust with your arm.

Can airplanes stop in the air?

No a plane doesn’t stop in midair, planes need to keep moving forward to remain in the air (unless they are VTOL capable). What it can do is simply turn around or go over/under the obstruction. VTOL means vertical takeoff and landing. It essentially means they can hover in place like a helicopter.

Can pilots open windows while flying?

It would not be possible to open the windows during normal flight. When the aircraft is not pressurized, either on the ground or if depressurized during the flight (intentionally or due to accident), then they can be opened. On most modern aircraft, the opening procedure is the same.

Can planes land on autopilot?

Many autopilot systems are capable of landing the airplane. Recently, some small airplanes have implemented an emergency system that will automatically land the aircraft on a runway, after advising air traffic control that there is an emergency, evaluating the weather and navigating to the runway.

How do pilots handle long flights?

Pilots keep flight deck lights up, and engage in conversation to help keep alert. If there are additional pilots, then there is a rest break (though on a flight like JFK – LHR, there might not be as the flight time is normally less than 8 hours). If there is not an additional pilot, then there are no rest breaks.

How long can a plane stay in the air?

Planes can now fly for 21 hours non-stop.

How long can a plane stay in the air without engines?

Flying at a typical altitude of 36,000 feet (about seven miles), an aircraft that loses both engines will be able to travel for another 70 miles before reaching the ground.

Can a plane fly with one wing?

No, an airplane cannot fly with only one wing. In order for a plane to stay stable in air, it has to maintain balance. With only one wing, the weight is shifted to one side of the plane.

What does LIFT do to a plane?

Lift is the force that directly opposes the weight of an airplane and holds the airplane in the air. Lift is generated by every part of the airplane, but most of the lift on a normal airliner is generated by the wings. Lift is a mechanical aerodynamic force produced by the motion of the airplane through the air.

Why do planes fly at an angle?

To generate a certain amount of lift requires that the wing have a specific angle of attack at a given speed. As the wings are more-or-less permanently attached to the fuselage setting the angle of attack requires us to pitch the entire aircraft, changing the deck angle.

Can a Cessna 172 fly upside down?

Yes. A Cessna 172 can fly upside down. In fact, some Cessna’s are used to train beginning acrobatics. As stated here, the standard planes need to be modified from gravity fed fuel to fuel injection or electric fuel pumps to assure fuel flow.
