How long can a helicopter hover in one spot? So How Does A Helicopter Hover In One Spot? How fast do helicopter blades spin mph?
A helicopter has two pairs of propellers – the larger ones at the front, above the cabin and a smaller one at the tail. The larger ones help in flying while the smaller ones stop the helicopter from spinning round when the big blades are turning.

How Does A Helicopter Hover In One Spot
As the propeller blades of a helicopter slice through the air, it creates a strong wind. The wind moves downward pushing the helicopter. The air beneath the blades thus, has greater pressure than the air above them. The blades are then twisted slightly so that air is forced downward. This creates a lift.
Flaps under the wings of an airplane create a lift in the same way. In fact, the rotor blades of the helicopter are really moving wings. The difference is that the whole airplane has to move forward in order to get lift, whereas the helicopter needs the propeller to fly in the air.
This is what enables a helicopter to go straight up or down or hover over one spot. In front of the pilot, is a ‘cyclic stick’. He moves it in the direction he wants to go and the helicopter flies that way. The cyclic stick works by changing the pitch of one blade at a time as it passes the side of the helicopter.
This means that one side of the rotor disc has more lift than the other, and the disc tilts. When the disc is flat, the helicopter hovers because all the lift force is straight up, keeping the helicopter in the air. If the disc is tilted, most of the force is still up, keeping the helicopter in the air, but some of the force pushes it and as a result the helicopter moves in the direction it is pushed into.
Helicopters can make sharper turns than airplanes and they don’t need a long runaway to take off or land – they can even land on top of a building.
In India, the armed forces use helicopters for many different jobs – because of their manoeuvrability, they are ideally used to transport people to places hard to reach easily: people trapped in jungles or mountains; patients to hospitals; or to rescue people in floods and landslides.
In certain countries, helicopters are also used to monitor traffic conditions and by the police to catch criminals!
