Helicopters

Hover

VTOL (Vertical Take Off and Landing) aircraft can hover as well as helicopters, but helicopters can do it more efficiently and, therefore, can do it for longer periods.

Pretty much any surface that's firm and flat enough.

Yes, google it, and one tour company comes up.

You have a certified professional fix it.Ask to see proof they are certified and do not take their word for it.

Technically, yes, since tornadoes are usually separated by at least several miles. However, in close proximity to a tornado the wind is too strong and too turbulent to savely fly a helicopter.

A black-hawk helicopter can hold 15 people 2 chiefs, 2 pilots and 11 troops

Responsible for the work on the Avionics of an Aircraft composed of the following:

communications, navigation and guidance, display systems, flight management systems, sensors and indicators, weather radars, electrical systems and various other computers onboard modern aircraft and spacecraft. It also includes the hundreds of systems that are fitted to aircraft to meet individual roles; these can be as simple as a search light for a police helicopter or as complicated as the tactical system for an airborne early warning platform.

Well, there are some airplanes which can be outrun by helicopters, but, for the most part, airplanes are faster.

Most helicopters used a kerosene based fuel, such as Jet A, Jet B, or - in the case of military aircraft of NATO countries - JP-8. However, helicopters which use internal combustion engines will use standard 100 Low Lead petrol fuel.

I believe it is called the UH 60 Black Hawk

To legally land in a residential area, you need the permission of the owner or manager of the property. You can only do so if the event will not cause harm or damage. It is a good idea to coordinate such events with local air traffic control, especially in a highly congested urban area, and always if the landing zone is within airport controlled airspace. So, if the neighbors don't mind, and the home owner is for it, then no problem. I once picked up a friend from one wedding reception point in his back yard, and dropped him and his new bride off at the second reception venue in the parking lot of a club not too far from their home, all with his neighbors snapping tons of photos and waving at us, as I had him get their blessings before the event.

It was not built then, but Leonardo da Vinci made a drawing of a helicopter in the 15th Century.

Tail rotor thrust is simple the sidewards force provided by the tail rotor. This is required to offset the gyroscopic motion created by the main rotor.

When the main rotor spins it creates toque in the opposite direction. The result, without a tail rotor, would be the main body of the helicopter spinning around in the opposite direction uncontrollably.

The tail rotor simply provide thrust in the opposite direction to this toque and thus allows the main body of the helicopter to remain stationary. The blades of both the main rotor and the tail rotor spin at the same revs. The pilot adjusts the pedals at his feet to change the amount of sidewards thrust thrust allowing him to control his lateral movement.

You need to be more specific. Fuel costs vary as do the size of the tanks on a helicopter.

The rotor, shaped like an aeroplane wing, creates lift in the same way. The problem is in maintaining stability, as it will cause the body of the helicopter to rotate, too. That is why most helicopters have a tail rotor, to counter that effect and grant the pilot stability.

cause helicopters are really fast

Anywhere they can land.

sometimes, but they need to be on both sides or else the helicopter will lose its balance and crash! it is not beneficial if you put the lights on the propellers because they will move so fast you can't see them...

Helicopters carry from 1 - 90 passengers

A helicopter requires air to generate lift from its rotors. Since the moon has no atmosphere, there is no air for the helicopter to push against and create lift. This makes it impossible for a traditional helicopter to work on the moon.

There's only so much you can do to make a helicopter go faster; most helicopter operators are more worried about how much they can lift.

Most guys who need to fly a lot faster than helicopters can don't buy helicopters in the first place. If you need to go 300 mph in an aircraft, and you don't need to land in confined areas or hover, you're better off with a Pilatus PC12 or a King Air.
