How close are we to flying cars?
Lexile

Even before the cartoon character George Jetson entranced kids with his flying car, people dreamed of soaring above traffic congestion. Inventors and entrepreneurs have long tried and failed to make the dream a reality. But that may be changing.
 
Nearly a dozen companies around the globe, including some with deep pockets such as European aircraft maker Airbus, are competing to be the first to develop a new kind of aircraft. It will enable commuters to glide above crowded roadways. A few of the aircraft under development are cars with wings. They unfold for flight. But most aren't cars at all. Typically they take off and land vertically like helicopters. Rather than a single, large main rotor, they have multiple small rotors. Each rotor is operated by a battery-powered electric motor instead of a conventional aircraft piston engine.
 
It's no sure bet that flying-car dreams will turn into reality. There are many obstacles. These include convincing regulators that the aircraft are safe. And, figuring out how to handle thousands of new low-flying aircraft over cities without collisions and developing batteries that will keep them aloft long enough to be useful.
 
But entrepreneurs are moving forward. They see a vast potential market for "air taxis" and personally owned small aircraft. These would transport people from the fringes of metropolitan areas to city centers as urban areas grow more congested and people spend more time stuck in traffic. They envision tens of thousands of one or two-person flying taxis. The taxis might deliver passengers to the rooftops of office buildings in city centers and other landing pads during rush hours.
 
"In as little as 10 years, products could be on the market that revolutionize urban travel for millions of people," said Zach Lovering. He is the leader of Airbus' project to develop an autonomous flying taxi. It is called the Vahana. The name means the mount or vehicle of a Hindu deity.
 
Uber released a 98-page report in October. It made the business case for air taxis. The company sees them as the future of on-demand transportation. Uber doesn't have any plans to develop a flying car itself. But the online transportation network is advising several companies that have aircraft in the works.
 
"The role we want to play is as a catalyst for the entire industry," said Nikhil Goel. He is an Uber project manager for advanced programs.
 
Some of the aircraft are drones that will be preprogrammed for each flight. They will be monitored or operated from the ground or a command center. Others are designed for human pilots.
 
It's unclear yet how much the aircraft will cost. The prices are likely to vary significantly. Some of the aircraft are designed to be individually owned. Others are envisioned more for commercial use. Designers hope that demand is high. If so, prices might be kept affordable through economies of mass production.
 
Several recent developments could make these aircraft possible. Advances in computing power mean the rotors on multi-copter drones can be adjusted many times per second. This makes the aircraft easy to control. Drones have also benefited from advances in battery and electric motor technology. Some companies, like Chinese dronemaker EHang, are scaling-up drones. That's so they can carry people.
 
Another aircraft under development is the Santa Cruz, California-based Joby Aviation's S2. It looks more like a conventional plane. But there are 12 tiltrotors. These are spread along the wings and tail. And some, like the Vahana, a cockpit mounted on a sled and flanked by propellers in front and back, don't really look like any aircraft in the skies today.
 
"In terms of what you can make fly in a reliable manner, the solution speed gateway that (computer) chips have gone through recently have literally opened the door to a whole new world of flying machine possibilities," said Charles Eastlake. He is an Embry-Riddle Aeronautical University professor emeritus of aerospace engineering.
 
But he also cautioned: "My best engineering guess is that people actually using autonomous air taxis in the next 10 or 15 years is possible, but definitely not certain. The challenges are big."
 
Key for many of the designs will be the development of longer-lasting lightweight batteries. Currently available batteries could probably keep an air taxi aloft about 15 to 30 minutes. Then it would have to land, experts said. Depending on how fast the aircraft flies, that probably isn't quite enough to transport passengers between nearby cities or across metropolitan areas, experts said.
 
Another hurdle will be winning Federal Aviation Administration certification for any radical new kind of aircraft. Approval of even small changes in aviation technology can take years.
 
The FAA said in a statement that it is taking a "flexible, open-minded, and risk-based approach" to flying cars. FAA officials have discussed with several manufacturers the certification of aircraft. These will be flown with a pilot in the beginning. Later, they will be converted to an autonomous passenger aircraft.
 
Reducing noise is another challenge. Air taxis will be taking off and landing in densely populated areas. So is creating enough landing pads to handle lots of aircraft at the same time. A new air traffic control system would also likely be needed.
 
"It's pretty clear that the existing air traffic control system won't scale to the kind of density at low altitudes that people are talking about," said John Hansman. He is a Massachusetts Institute of Technology professor. He chairs the FAA's research and engineering advisory committee.
 
NASA is developing an air traffic control system for small drones. It could perhaps be expanded to include flying cars.
 
"There's no question we can build the vehicle," Hansman said. "The big challenge is whether we can build a vehicle that would be allowed to operate in the places where people want to use it."

    I think its hard because you cant just get a regular car and put wings on it and expect it to fly in the air that alone takes years in the making to just get every little detail to work. For a devlpor to come out with one that works.

      i agree. You can't just pull something out of a fairy tale and expect it to be that easy. You have to expect some work to try to get something like that just appear out of nowhere.

    I never noticed that a lot about flying cars came from the jetsons. that was very interesting.

      Me neither person but if you look close there is. The jestons were actually the first cartoon to ever have flying cars. As the article states though were really far away from flying cars.

    It is difficult because you can't just make something and it will turn out the best right away. It takes failure to fix mistakes, then it will turn out better than the last.

    cause some times we dont have the stuff to make flying cars

    I think if we had the cars that they are talking about I think no body could afford the car because the are high teck cars and they would cost to much to afford and buy that why I think we shouldn't buy them care or have them cars in the futcher.

    people might've all the resources to make cars and they haven't found a way to make it safe for people.

    It is so difficult to make a flying car because of many reasons. A reason is because there are cities with high buildings and that could cause many problems. There would be many problems because from this article it seems like they will be a low-flying aircraft and with the tall buildings they could crash. Another reason is that entrepreneurs would have to find a developing battery that will keep them aloft long enough to be useful. One more reason is because a new air traffic control system would also likely be needed and they need to find someway to make one. There are more reasons it's difficult to make a flying car but there are much more because there would be a lot of problems with creating a flying car.

    i never knew that they had got that idea off of a aircraft
