A:The average speed for a four-seat helicopter is 130 to 145 miles per hour. Because smaller helicopters have smaller engines, the average speed for a two-seat is 90 to 105 mph. The fastest helicopter on Earth as of 2014, the X3 Eurocopter, can fly at 300 mph.
A:The record for maximum altitude achieved by a helicopter is 40,820 feet. This record was set on June 21, 1972 by French aviator and test pilot Jean Boulet, who was piloting an Aerospatiale SA 315B Lama.
A:The Large Hadron Collider is a particle accelerator and is the largest of its type in the world. It is used for conducting experiments in theoretical physics and was built with a focus on determining whether the Higgs boson particle exists.
A:There are about 20,000 airplanes in the world as of 2013. Aircraft maker Boeing projects demand for new airplanes to top 35,000 over the next 20 years. The new planes are expected to meet rising demand and to replace older, less efficient models.
A:Airplane travel allows for shorter travel times and travel efficiency; it allows people to see the world and it creates millions of jobs across the globe. The world is now global and there are no true borders thanks to air travel.
A:Kelly Blue Book, Edmunds and the National Automotive Dealers Association provide calculators to help consumers determine how much a used car is worth, advises Investopedia. Mileage, condition, included equipment, color and geographical location most strongly determine the value of a used car.
A:Winter is the best time to buy a new car, according to United Services Automobile Association, known as USAA. Winter months often offer the highest potential for discounts, notes USAA. Dealerships must clear inventory in order to make room for the newest car models, explains USAA.
A:To offer a car on eBay, the seller must gather information about the vehicle, create a listing, monitor the process, and then close the deal by arranging for payment and delivery, according to the company's website. EBay walks customers through each step of the process, if needed.
A:According to Samarins.com, a good mileage figure for a used car is 155,000 or less. While low mileage is desirable in a used car, it is not a guarantee that a vehicle is in reasonably good shape for its age.
A:In the United States, Oregon is the least expensive state in which to purchase a car as of 2014, while Alaska, New Hampshire, Montana and Hawaii follow close behind.

A:According to TopSpeed, a 2013 Ferrari F12 Berlinetta can reach a top speed of 211 mph and maximum engine speed of 8,700 rpm. The rolling resistance is low in order to reach peak engine speeds rapidly.
A:Among the best SUVs for families are the Nissan Rogue, Nissan Pathfinder, Chevrolet Traverse, Honda Pilot and the Ford Flex, according to a study conducted by Kelley Blue Book in 2014. The models were rated based on cargo space and family friendly features.
A:Although laymen often use the words "motor" and "engine" interchangeably, from a technical point of view, an engine uses fuel to create heat that it converts into motion, while a motor uses electricity to produce motion. Historically, an engine is technically any machine that converts energy into force, such as a catapult, according to Reference.com.
A:Hail damage can be corrected using a heat method, a specific hail repair kit or through the use of professional services. The heat and repair kits are at-home methods that are less likely to work than professional hail repair.
A:Many times, a vehicle acts differently when it is about to run out of gas. Common signs include sputtering or shaking when the fuel level is very low. Ultimately, a car that runs out of fuel ceases to function, leaving the driver stranded until fuel is added to the tank. In addition, when a car runs out of gas, there is an increased risk of having the fuel pump fail.
A:A muffler reduces the exhaust noise of a vehicle by blocking and reflecting sound waves. Inside the muffler is a series of baffled chambers and perforated barriers that break up the high-velocity sound waves as they flow through the device, reducing the overall noise level.
A:The first step in fixing a deep scratch on a car is to apply a polishing compound. This will remove the clear coat on the exterior of the car. Next, it is important to ensure the paint color used will seamlessly match the automobile.
A:As long as the cables are properly insulated, jump starting a car in the rain does not add to the immediate danger of jump starting the car, but exposing the battery to rain or other forms of moisture causes corrosion and reduces the life of the battery. If bluish-white matter accumulates around the terminals following exposure to moisture, it is important to clean them thoroughly to avoid faulty connections.
