How would a helicopter remain stationery in air?
A helicopter can remain stationary in the air by adjusting the pitch of its rotor blades. By tilting the rotor blades slightly forward or backward, the helicopter can control its vertical lift and horizontal movement, allowing it to hover in place. Pilots use the helicopter's collective and cyclic controls to maintain a stable position.
How does the helicopter stay stationary in the air?
Two things keep a helicopter flying, and another keeps it flying straight. To take off: 1) The blades are shaped like the wings of an airplane and create a difference in pressure (high underneath the wing, low above). This difference in pressure "pushes" the helicopter upwards (lift). But because of gravity, however, there might not be enough lift to take off from the ground. 2) In order to take off, the blades must rotate at supersonic speeds (to be stronger than gravity's push downwards), this make it possible to gain altitude. To "Fly:" 1) A helicopter's blades in air act like a boat's propeller in water. If the blades rotate at an angle, it will start moving. To make the helicopter hover, the blades must be perfectly straight up. At the same time, the rotating blades make the helicopter itself rotate the other way (about the axis of rotation). In a GPS, the helicopter would not be going anywhere like this (with no angle on the blades), but the Direction at which it is looking will be changing in circles 2) Helicopters need a way to fix this crazy-out-of-control spinning. They can use a tail rotor for this, but they can also use a "twin" set of blades that rotate in opposite directions (counter-rotating blades). With the addition of counter-spinning blades, now the GPS will be pointing at 1 direction. in summary: 1) By keeping the blades rotating fast enough to be lifting with the same force as gravity is pushing down, the altitude is kept the same. 2) By keeping the Blades from spinning at an angle, the Helicopter does not move to the sides. 3) By using a counter-rotating blades set, the helicopter is able to keep looking at one direction. with these 3 things, Helicopter are able to hover in air, and their GPS can be kept and a fixed height, at fixed position on a map, and at a fixed direction.
How does a helicopter hover in the same spot?
The lift/propulsion method used by a helicopter is capable of producing an overall thrust vector with virtually no horizontal motion. The lift method of planes (fixed wing), requires movement to produce lift. There are many possible helicopter configurations - most designs use some variation of multiple rotors placed in such a manner that rotational force is compensated for, allowing stable flight. Lift is able to be generated because the rotors (which are essentially just spinning wings) are still moving through the air, while the airframe overall stays in the same place.
If you jumpedup and down on the roof of a moving train would you land in the same place?
No, you would not land in the same place since the train is moving. Your horizontal velocity would be combined with the train's velocity, affecting your landing position.
How does air resistance affect a falling helicopter?
the same that it would affect any falling object. The higher the air resistance the thicker the air density. This will result in a higher drag coefficient and will slow the fall of the object.
How long can helicopter hover in the same spot?
Indeffinently within fuel limitations, or system temperatures.
If a helicopter kept stationary about 10 meters from earth after 10 hrs if it landed down vertically what will be its position either same or different?
The position would be roughly the same.

What can helicopters do that airplanes can't?
Hover in one place. Planes must have air moving over their wings in order to maintain lift. That only happens if the plan is moving. The blades of a helicopter get their lift from the same phenomena, but since they are in circular motion, the helicopter does not have to move horizontally to keep air moving over them. In all fairness, there are some VTOL aircraft that can hover in place but they do it by directing the exhaust from their jets downward or by rotating their wings so that they are getting the same effect as a helicopter.
How is a humming bird like a helicopter?
Well, isn't that just a happy little comparison! A hummingbird is like a helicopter because they both have the ability to hover in one spot. Just like a helicopter's rotor blades, a hummingbird's wings move in a circular motion to keep them suspended in the air. It's nature's way of showing us that even the smallest creatures can be mighty and impressive.
Why do flies hover in the same spot?
Flies hover in the same spot because they are able to use their wings to maintain a stable position in the air, allowing them to stay in one place for extended periods of time. This hovering behavior helps them search for food, mates, or potential threats in their environment.
How long can helicopter hover in the same spot close to the ground?
This will mostly depend on weath(wind/tubulence mostly). and in these conditions. the skills of the pilot. if perfect weather(for flying) until it runs out of fuel, or become unstablized.

What is differences chopper and helicopter?
Chopper is the nickname for helicopter. It's the same aircraft.
How do you charge an air hogs hover assault?
Turn air hogs hover assault switch to off (O) position.Turn air hogs hover assault charger to charge (CHG) position.Open charger panel (under switch) to expose cable.Plug cable into port on helicopter next to switch.DON'T MESS WITH IT! it will mess the charger up and you will have to reset your connection.Wait until charger flashes both red and green at the same time- not alternating.Unplug cable and happy playing!
When a train won't stop would it work if a helicopter hooked a chain to the train an pulled back?
A very larg helicopter may be able to take off with an added 50,000 lbs. of weight. A good sized modern train is going to be significantly larger than this. The helicopter's blades would likely give out as they are suddenly reversed if you just "slammed on the brakes" so to speak. If you had the helicopter going at the same speed as the train, and slowled the helicopter down as much as possible, the train would eventually stop if the locomotives were not powering the wheels (it would stop without the helicopter, too, and would be infinitely safer for the helicopter pilot). If the locomotive is powering the wheels, the helicopter's not going to do a whole lot.
