Can planes just stop in the 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.

Can an airplane escape Earth’s gravity?

Part of the problem is Earth’s gravity. You need to escape it in order to reach space. This requires a minimum speed of mach 33 (25,000 mph). The current world record for fastest plane is only mach 6.7 (5,140 mph).

How do planes not get pulled down by gravity?

An airplane wing is shaped so that the air is deflected downward as the wing passes. Because air is a fluid (a gas), both the top and the bottom surface of the wing deflect the air. A plane must be built so that lift and thrust are stronger than the pull of gravity and drag by just the right amount.

Can a helicopter stay still in the air?

A: There are no horizontal forces, as the helicopter is not moving left or right, so there is no drag or horizontal thrust. The blades generate a vertical lift, and when this is exactly balanced with the force of gravity, the helicopter remains stationary.

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.

Is lift equal to gravity?

The opposing forces balance each other; lift equals gravity and thrust equals drag. Any inequality between thrust and drag, while maintaining straight and level flight, will result in acceleration and deceleration until the two forces become balanced.

How does a plane fly without gravity?

The plane defies gravity by travelling at a critical velocity beyond which the lift caused by the wings( which acts on the Centre of Gravity of an Aircraft) negates and starts exceeding the force of gravity acting on the Aircraft….

Why can’t airplanes go straight up and let the earth pass beneath?

Why can’t airplanes go straight up and let the Earth pass beneath? The answer is – NO, you cannot have an airplane go straight up and let the Earth pass underneath to reach your destination, unless you are willing to burn an incredibly large amount of fuel and make the journey downright uneconomical.

What is the relationship between lift and gravity in a plane?

When in level flight lift generated by angle of attack or by Bernoulli’s Principle is equal to the force of gravity downward. When climbing, lift and vectored force from thrust are greater than gravity. When descending, lift is less than gravity.

How high can an airplane fly out of the Earth’s atmosphere?

Theoretically an airplane could maintain a flight altitude just a little over 1/64th of an inch out of level and circumnavigate the entire globe. I say theoretically because there are so many forces involved the plane’s computer or the pilot are always making corrections.
