They technically do both, as they fly when moving (nothing needs to touch the ground) and hover when standing still (unless they are turned off). This is assuming, of course, that altitudes less than a foot are considered flying.

To add: hovercraft can lift off, without their skirt, as they make fond use of the so-called "ground effect", much like helicopters do at a greater altitude. They keep lifted by sitting on the rotation of air beneath the vehicle and move forward by propelling the air behind the vehicle, rather than sitting on a big, inflated balloon (like many people tend to think). The skirt only serves as a mean for stability.

Technically, the hovercraft does fly, but is not considered to be an aircraft, whereas it does not elevate to great heights. Thus it is called a "hovercraft". People who operate hovercrafts, however, are generally referred to as pilots.

airplane, not airplan. you can't get an airplane in the game, though there is a few mods for pc, and there are helicopters.

Several blimps (Goodyear and Fuji) are used at sporting events and can be seen either live or on TV.

there isn't any that i know of but if you cant find any instructions just Google pyramid and then go to images and go to the best picture and just start building

Calgary has several Hobby and RC shops from which to purchase a Radio Controlled (RC) Model Aircraft. Look through local listing or internet map site for these stores: Action Hobby, PM Hobbies and Model Land. An Alternative would be to contact the Calgary Miniature Pylon Racing Association, an RC Airplane Club in the Calgary area.

very carefully

Before you start on a project like that, you need to prepare the builder. You take an Airframes and Powerplants course and learn the techniques for building, then you work with a certified A&P and drive rivets, cut patches, pull motors, re-cover wings and balance flight control surfaces under his tutelage until you have a good grasp of the intricacies. Then, you link up with other builders who have experience on the type you want to build. While you're at it, you probably ought to be the one to test-fly your creation so you ought to get you your private pilot's license. You'll need to know how one is supposed to fly and what to do in an emergency before you can safely evaluate your own creation.

Model airplanes can be made from a variety of different materials. The most commonly used materials include plastic, metal, wood, fibreglass and synthetic resin.

This entirely depends on the size of the ship. The larger the ship, the more it can carry. Care also has to be given to the design of the ship. If too much weight is stored too high the ship can lose its stability and roll over in a storm.
According with the research I have been doing for a long period of time, the biggest Container Vessel in the World can have a Capacity to carry up to 180.000 tonnes, which means 9000 containers of 20 tonnes each. Francisco.

Wood, canvas, fiberglass, carbon fiber, stainless steel, aluminum, steel, titanium alloy and even rubber have all been used as structural elements in aircraft.

Piston engines are typically made mostly from aluminum and steel by weight with smaller components made from other materials.

Jet engines are made from steel for shafts and bearings, titanium for fan blades, disks and low pressure compressor blades and extensive use of nickel superalloys for the combustor, seals and turbine components. Newer turbofans, like on large airliners, have composite fan blades and composite containment structures to contain engine components in the event of a rotating component failure.

Some of the earliest model airplane kits date back to as early as 1910. They retailed for $4 to $6 which was a substantial amount of money considering that the average working-class salary was $20 to $25 per week. Model airplanes were obviously toys for rich children as the average family would never be able to afford them.

It was a new and individual way of transportation that got you where you needed to go much faster. It made the world a much speedier and smaller place what with information traveling faster too.

Because of the shape of the wing, the distance over the top is longer than the distance via the underside. Therefore the air has to travel faster over the top. Now Bernoulli's Principle states, the greater the speed of a fluid the less the lateral pressure, ergo the pressure is less on the top of the wing, and lift occurs.

Making an aircarft is not easy. It takes time and effort. First you need to find what are all the parts and other things required to build it. Then you have to build it. Only experienced persons can build even small aircrafts like aeronautical engineers, airplane mechanics etc..

No airplane goes faster than the speed of sound wich is 1000km per hour due to safety reasons.

A blimp is a version of a dirigible, it is non-rigid and is kept in shape only by the hydrogen or helium inside it. those are the only gases lighter than air, so they float through a high-oxygen atmosphere. a blimp is usually propelled through the air by a large fan.

Cessna currently makes both piston-engined and turbine-powered aircraft.

Assuming you mean a piston engined cessna, the engine works basically the same way as the engine in your car. Most small piston-engined aircraft use an air-cooled opposing 4 or 6 cylinder engine very similar to the engine in an old air-cooled volkswagen.

Aside from that the other major differences are that aircraft engines usually use a solid-state magneto instead of an ignition coil, and that aircraft engines allow the operator to adjust fuel mixture levels en-route. The magneto is used so that the ignition system can be made independent of the aircraft's electrical system. Even if the electrical system fails entirely, the engine will keep running. The mixture control allows the pilot to adjust fuel mixture in-flight in order to compensate for the lower air pressures at high altitudes. If the aircraft were run at the same mixture all the time, as an auto generally does, the spark plugs would quickly become fouled by carbon and ash deposits.

4 forces act on planes

Lift pulls the plane up

Gravity pulls it down

Thrust pushes it forward

Drag pulls it back

These 4 forces together help move the plane through the air and without these forces an airplane wouldn't fly

When an airplane takes off the thrust is thus increased and the plane can take off from the ground

There are several qualifications one must meet to become an aircraft mechanic, including reaching 18 years of age, and being able to read, speak, write and understand English. One must also pass written, oral and practical exams.

Nothing is waterproof, especially considering the high stresses involved in an airplane accident. The flight data recorder is water resistant. It is also designed to minimize the probability of data loss even if it does get wet internally.

1 gallon of jet fuel weighs 6.79 pounds.

Some. A few yeas ago this would have been an absurd idea because of the public's fear of flight controls being messed with by mobile phones etc. onboard, but nowadays you an find WiFi on, for example, Virgin America planes and Delta's domestic fleet. However, you provably have to pay for the service (you definitely have to on the Virgin flights)
