A helicopter doesn't need a solid surface to fly over, however when hovering, it takes a little less power to maintain a stationary hover over a surface than up in midair. That's because at normal hovering height (3 ft.) a column of air pressure (called ground effect) is built up underneath the rotor blades that assists the aircraft in maintaining it's altitude.

Why does a helicopter lose altitude when flying over a water surface?
When a helicopter flies close to a water surface, the air below the helicopter is disturbed by the movement of the rotor blades. This disturbance can affect the lift generated by the rotor blades, leading to a loss of altitude due to reduced lift. This phenomenon is known as "ground effect."
How do you find the surface area of two similar solids?
you put: a squared over b squared = surface area of the smaller solid over surface area of the bigger solid
How can I prevent a solid layer surface forming on hot chocolate?
A solid layer forming is due to oxidation of the surface. This cooling effect is due to the surface being exposed. To prevent this, you would need to get rid of all of the air and put a layer of plastic wrap over the surface without any air under the plastic.
What friction solid surface slide over each other?
When a solid surface slides over another solid surface, friction occurs due to the resistance to motion caused by the microscopic roughness of the surfaces. The rougher the surfaces, the higher the friction generated between them. The friction force depends on the nature of the materials in contact and the force pressing them together.
What are the chances of dying in a helicopter crash?
If you are flying over a dense forest, over deep water, and over high snow, and the helicopter suddenly crashes you have a pretty chance of getting out of the helicopter.
Are there cheats for the helicopter game?
no get over it
How does a helicopter achieve drag?
A helicopter experiences drag through air resistance as it moves through the atmosphere. The main sources of drag in a helicopter are profile drag from its overall shape and skin friction from the airflow over its surface. Additionally, rotor tip vortices and induced drag generated by the rotor system contribute to overall drag.
How does breaking up solid speeddissolving in liquid?
Breaking up the solid into smaller pieces increases the amount of surface area exposed to the solvent. Because the solvent is acting over a larger surface area, the rate of dissolving increases.
Can you get a bridge in cityville?
ya but u need population 5000 and an expansion going a ross the river but before this u need to see a helicopter hovering over the river
When solid surface slide over each other the kind of friction that occurs is called blank friction?
sliding
What does helicopter parenting mean?
"Helicopter parents" hover over every aspect of a child's life trying to control and protect the child. Unfortunately, starting at about age 8 or 9, children need to start to manage some of their own affairs and making their own decisions. The children of "helicopter parents" have difficulty in learning to manage their own lives and making their own decisions as adults, because they've never done it before.
What is the best to surface to set an above ground pool on?
3"/75mm of sand over a solid level surface.
