# You asked: What features allow planes to fly?

Contents

It flies because of four forces. These same four forces help an airplane fly. The four forces are lift, thrust, drag, and weight. As a Frisbee flies through the air, lift holds it up.

## What effect allows planes to fly?

According to a principle of aerodynamics called Bernoulli’s law, fast-moving air is at lower pressure than slow-moving air, so the pressure above the wing is lower than the pressure below, and this creates the lift that powers the plane upward.

## How does an aircraft fly?

Airplane wings are shaped to make air move faster over the top of the wing. When air moves faster, the pressure of the air decreases. So the pressure on the top of the wing is less than the pressure on the bottom of the wing. The difference in pressure creates a force on the wing that lifts the wing up into the air.

## How Can planes fly upside down?

Stunt planes that are meant to fly upside down have symmetrical wings. They don’t rely at all on wing shape for lift. 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.

## Can airplanes stop in the air?

Techincally, there is only one way for the aircraft to remain hanging motionless in the air: if weight and lift cancel each other out perfectly, and at the same time thrust and drag cancel each other out too. But this is incredibly rare. To stay in the air and sustain its flight, an aircraft needs to be moving forward.

## What are 3 things needed for flight?

The four forces are lift, thrust, drag, and weight.

## What are planes used for?

Generally, all planes are used to flatten, reduce the thickness of, and impart a smooth surface to a rough piece of lumber or timber.

## How do planes fly against gravity?

Planes do not actually defy gravity, though. Instead, the tilt and area of a plane’s wings manipulate the air particles around the plane, creating a strong enough lift that the force of gravity is overcome by the force of the air beneath the wings.

## Why do planes have wings?

A: Wings are a critical part of airplanes because they are used for lifting, turning, landing, and controlling the airplane! Without wings, airplanes simply could not fly! … This curve makes air on top of the wing move faster than air on bottom, using Bernoulli’s principle to push the airplane into the air.

## Which animal can fly upside down?

The design of a hummingbird’s wings differs from most other types of birds. Hummingbirds have a unique ball and socket joint at the shoulder that allows the bird to rotate its wings 180 degrees in all directions.

## How do airplanes fly answers?

Airplanes fly as a result of the forward force of thrust being greater than the backward force of drag. … The upward force called lift is caused by a difference in air pressure above and below an airplane’s wings.

## How slow can a plane fly?

Technically this is the so-called ‘stall speed’, where air passes over the wings fast enough to sustain altitude, and for small planes this can be less than 50km/h (31mph). But at such low speeds, the aircraft is easily destabilised, and could fail to leave the runway.

## Does Aeroplane fly in rain?

Flying in Heavy Rain

Rain doesn’t usually affect a flight much. Combining with hefty winds causes extra challenges to flight planning. The combo can even cause a change of route or a delay if the conditions are extreme. But generally speaking, airplanes are well-equipped to deal with a bit of the wet stuff!

## Can airplanes land on water?

The good news is that modern aircraft can indeed land on water – otherwise known as ditching – but they’re not actually designed to do so. … The plane would stay afloat long enough for all the passengers to exit the aircraft via the inflated slides.
