# Can a passenger plane stand still in the air?

Contents

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.

## Can passenger plane stay still in air?

You can’t have any object “stand still” in air – the laws of physics don’t allow it. But as others have explained, an aircraft can appear to remain motionless over ground and stabilized at altitude like a helicopter because of a headwind or through vertical engine thrust nozzles.

## Why do some planes stand still in the air?

For a plane to stay in the air, the lift force needs to overcome the force of gravity. Additionally, the thrust must overcome the drag force, which resists the plane’s motion through the air.

## How long can a plane stay still in the air?

Planes can now fly for 21 hours non-stop.

## Can a plane stop in mid-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.

## Can a plane take off without moving?

Aircraft rely on airflow over the airfoil (wings/tail etc) to produce lift – which is independent of the movement of the tires. This means that with enough air going over the wing, the aircraft will fly even if it isn’t moving forward at all relative to the ground.

## Can a helicopter stop in the air?

A helicopter that is flying forward can stop in mid-air and begin hovering very quickly.

## How Slow Can a passenger 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 a plane reverse?

Direct answer to your question: No, the engines do not reverse. However, there is thrust reverse on most jetliners to help the deceleration by this deflected air. John Cox is a retired airline captain with U.S. Airways and runs his own aviation safety consulting company, Safety Operating Systems.

## How do airplanes stay in the air without falling?

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.

## What happens if a plane stalls mid air?

When an airplane stalls, it’s no longer able to produce lift. … When this occurs, there’s an insufficient amount of air traveling under the airplane’s wings to keep it up. As a result, the airplane will drop, thereby reducing its altitude, until the angle of attack is correctly adjusted.

## Do planes release human waste?

It is a mixture of human biowaste and liquid disinfectant that freezes at high altitude. … Airlines are not allowed to dump their waste tanks in mid-flight, and pilots have no mechanism by which to do so; however, leaks sometimes do occur from a plane’s septic tank.

## What happens if an airplane goes too high?

When the plane gets too high, there is insufficient oxygen to fuel the engines. “The air is less dense at altitude, so the engine can suck in less and less air per second as it goes higher and at some point the engine can no longer develop sufficient power to climb.” …
