"Roadable Aircraft" Moving Towards Launch

We discussed Terrafugia's plans for what they don't like to call a "flying car" — rather a "roadable aircraft" — last spring. The Boston Globe has an update on Massachusetts-based Terrafugia and its fight to get airborne in these parlous times. "The last serious attempt to bring a car-airplane hybrid to market was the Aerocar, in 1949. According to Carl Dietrich, chief executive of Terrafugia, that company built six prototypes. It needed 500 orders in order to gear up for mass production, but it never got there... 'It can be hard to explain the value of this to non-pilots,' Dietrich says, 'but when you're a pilot, the problems of high costs, limited mobility on the ground, and weather sensitivity are in your face, all the time.' The company says more than 50 of the vehicles have been pre-ordered. The target price is $198,000."

I assume that the target market for this type of vehicle isn't the lay driver who wants a "flying car" to dodge traffic and be cool, it's the private pilot who wants to be able to fly somewhere and not have to worry about ground transportation at the receiving end.

If I were a pilot, that's what would keep me from actually using a small plane to get around -- because unless my business was at the airport, I'd be stuck.

I'm holding out for personal teleportation tech.

1. Punch in the place you want to be.
2. It "dials" to see which of the [X] receiving platforms are unoccupied there
3. Magic happens.
4. You're standing on a teleport pad roughly where you want to be, get off, and someone else probably arrives soon after you.

As long as I'm dreaming I'd like a pony and a fully functional gynoid with a remote control.

The big questions are

1: how much extra will a roadable airplane cost compared to a normal one?
2: how much will this cost to insure (i'm betting a lot, particularlly for fully comprehensive cover)
3: how long will it take to convert between airplane and car modes?

In summary will it really be cheaper and/or more conviniant than hiring a car at your destination airport?

1: how much extra will a roadable airplane cost compared to a normal one?

The people who want to build the aircraft mentioned in TFA plan to sell it for about $200k. A used, but very serviceable, two seat "regular" airplane can be bought for around $20k to $30k and a four-place for about $40k to $50k. So, the roadable airplane seems to cost between 4x and 10x as much as a normal one. And, if having a new airplane is important to you, you could spend $120k for a brand new Cessna Skycatcher, which comes from a company with an established track record of building reliable airplanes--and doing it profitably, which means that spare parts will continue to be available for many decades that well-maintained airplanes last.

For the price of a new roadable airplane, you could buy a used normal plane and have enough left over for a few luxury cars (or a whole fleet of Civics/Fits/Corollas/Yarii) to park at your most frequent destinations. Consider also that a normal airplane, because it doesn't need to make so many compromises, will be better at being an airplane than this roadable plane will. And the same goes for the normal car being a car.

4b. Alternatively, due to a slight miscalculation of departure times somebody is teleported to your location while you are still on the teleport pad, instantly accelerating the atoms formerly known as "your body" into all directions away from their former positions in a bloody explosion.

I should hope that anything that flys, regardless of how popular it becomes, still requires a pilots license and that the skill needed to attain such a license remain quite high. Lay drivers manage to kill 43,443 people in 2007.

Absolutely correct! Most people are horrible pilots of anything they operate and make poor transportation decisions. They do whatever they want, with little regard for what the people around them are doing. Every region has different ways of driving poorly, but in my region of Texas, they don't know how to maintain speed while cornering or going up hills, they don't know how to merge or yield, they don't signal their lane changes or turns, they drive at night like they are night blind, they drive either 8 mph under the speed limit or 15 mph over the speed limit, they blare loud music out of their vehicles, they swerve across 3+ lanes of traffic at the last minute to take an exit or entrance ramp, they use all available space to make a turn (even breaking State law to make a right-hand turn across as many road lanes as are available), they tailgate, they sit at red lights blocking the right-turn lane from turning because they won't make the legally-allowed right-hand turn on red, they won't make a left turn on a solid green light (they have to have a green arrow, or they won't even attempt the turn), they pace vehicles, especially while driving in the other driver's blind spot. In the last few weeks, I've encountered several drivers who simply stop and remain in the middle of the road whenever they have a problem, even in a 45 mph zone. The concept of a free flow of traffic is alien to most Texas drivers, and many of them drive like they have spent their lives on a country road without having to consider other drivers.

Texas drivers are mostly annoying, and only somewhat hazardous. In Virginia, especially closer to D.C., the drivers are more ruthless, more vicious. If you signal a lane change, they usually will attempt to block you from changing lanes.

I've long said that when flying cars become marketable, I'm installing an anti-aircraft gun in my front yard.

The same idea apply to sailing open water, yet I have seen boats run right into buoys and over other boats' anchor lines. I've seen sailors lock the wheel and then run below decks to grab something, leaving the boat going full speed with no one at the wheel. In open water, I frequently lock the wheel (I stay on deck) and eat a sandwich or apply sunscreen or whatever. On open water at times it can be difficult to remember to look up every fifteen seconds, getting sidetracked is easy. There is a salty saying "There's three types of sailors: those who've gone aground; those who haven't, but are going to; and liars." The danger isn't in the featureless open space, it's near the destinations, navigation points, and obstacles. That's where the degree of attention required changes more quickly than is often accounted for. Everyone gets used to a big open space and they lose the focus to avoid the easiest obstacles, that's why I sited such common driver distractions as putting on make up, talking on the phone, and yelling at the kids in the back. Drivers do these things now, with something that demands as much attention as highway driving, and I think that a less demanding environment would exacerbate these behaviors and habits, making those drivers completely unaware of when they were entering a situation that demanded more attention. Compare your own level of focus between driving on a long straight stretch of road vs a winding road.

ouch, telefragged

Re:Uses

[lakeland]

I don't think comparing new to used is fair, so lets look at your new prices - $200k vs $120k. That means you're spending about $80k extra getting a road-certified plane - probably a bit more in reality as parts are likely to cost more, etc.

You suggest purchasing a car for each airport that you plan on flying this plane to. Lets say you purchase just two cars for $15k each, using rentals whenever you go anywhere else so you've now got a buffer of $50k. How much will you pay in hanger fees, car fees, and car storage fees, not to mention maintaince on three veichles instead of one?

$300/month seems fairly conservative for hanger fees. Add a couple hundred extra for the car fees and your Cessna is looking at being more expensive after about eight years.

[Bitsy Boffin]

Here's the thing. Big Sky Theory only works outside of airways (official, and unofficial) and especially outside airport circuits. Inside the circuit, the pilot is rather busy getting setup for landing, running through checks, at uncontrolled fields they need to ascertain the runway in use, wind conditions etc.. unfortunately so are the other 10 aircraft all converging on that small piece of airspace. This is when most mid-air collisions happen, not in the big sky, but in the little patches above airports.

Not much of a plane either

Quote from their website:"Drive to your local airport, fly up to 400nm, land, convert, and drive directly to your destination."

Call me back when this thing can fly above one billionth of a meter.

EXORBITANT?

[way2trivial]

then don't put it in one
many many small airports charge a $10.00 tiedown fee to tie it up on the tarmac, waived if you buy fuel..

FFS why put it in a hangar?

Re:EXORBITANT?

[Free the Cowards]

Because while being covered with dimples may work well for a golf ball, they do considerably less aerodynamic good when applied to an airplane by a passing hail storm.

You had your flying car in 1979...

[Nick Driver]

...and it was called the General Lee

Didn't fly very far and the nose-first landings were a bit on the rough side.

Re:Solution in search of problem?

[Snad]

Renting a car is fine if you're flying somewhere where such is available.

When I used to fly little Cessna 152s around the place we would often land at "airfields" that were little more than converted sheep paddocks with a gas pump off to the side. The nearest rental car place would have been 100 miles in any direction you cared to choose.

For that kind of flying, something like this would be practically nirvana. For flying between international airports, yes stick with the rental Chrysler or something...

OLD NEWS!!! ALREADY BEEN DONE!!

[gsgriffin]

Gosh. I remember seeing this done a long time ago. It's really simple to do. In fact, you can use spare parts from around your house to build it...that is if you live in an old house with a large fireplace hood. The vehicle may look a little strange and make funny sounds while driving down the road, but you can always sing a little tune to mask the sound. Sorta sounds like, Chitty-Chitty Bang-Bang. You get used to it.

Nice idea, but there are 1 or 2 problems...

[Anonymous Coward]

Before you say anything else, yes I am a licensed pilot so here we go...

Parking by brail. Yes I am sure you have all heard about it and I am quite sure most of you have done it to one degree or another. That is when you just touch the car behind or in front of you while trying to parallel park. The thing is, with aircraft, if you graze anything or your aircraft is grazed by anything else, much less dented, the aircraft is instantly grounded until inspected by an A&P ( Airframe and Power Plant mechanic) and certified as being once again airworthy. So parking will be a pit of a problem.

Now arguably people that buy one of these will be pretty well-off in the money department, but if they want to use it as intended they have to drive the thing through all kinds of traffic with the hazards therein.

There are unprotected control surfaces on both ends of the beast. One commuter reading the paper or reaching for their coffee bumps you and you now have damaged control surfaces and again the machine is grounded.

The wings are hinged to retract and fold. When winds are folded and not locked together the only structural stiffness is the hinges. Just that thought gives me pause. Drive the Mass Pike or any other commuter road lately? I don't know about yours but mine have serious potholes and undulations, not to mention serious stop and go driving with a lot of hard braking. I just cannot see this thing standing up to the kind of beating your car takes on a daily basis.

Safety... I cannot imagine how they are going to get this thing through the DOT when clearly in order for this thing to fly it has to be made out of some seriously light weight materials. So it is pretty much going to have almost no crash protection, side impact bracing, airbags, etc etc because all that adds a lot of weight. They do state on their website that it is "Designed to automotive crash safety standards", yet they do not say that is has passed DOT standards as yet.

Useful load, they are pretty careful not to say what the useful load is. Useful load is the weight the aircraft can carry. They do not state the empty weight of the aircraft. They do state a MAX Gross takeoff weight of 1320 lbs, and a full fuel load of 120 lbs. They do claim it can carry two passengers. The weight of an FAA "Adult" is 175lbs. So the useful weight is more then likely not much more then 500 lbs. This would put the empty weight at about 820 lbs.

Ok, so just how much impact safety can you build into something that has to be 820 lbs or less? IMO not much. So even if the thing manages to become street legal, I am for one am not driving it on the road, because it will just be CRUSHED by a 3300 lb VW Jetta or Passat, or Lexus or whatever, never mind a bus or a water delivery truck. This thing will more then likely cause more then a few accidents out of sheer novelty as people stair at it rather then pay attention to their driving.

That brings to mind insurance. Now insurance for aircraft is a lot like cars, it is broken down into the Airplane itself and Liability. From the liability POV I don;t think it would be that bad, but from the collision aka Comprehensive POV if I was an insurance company, I would either not insure your airplane while in operation of roads, or I would charge you a massive premium for the reasons I listed above. Any kind of a minor fender bender will render this thing non-airworthy and require a trip to a FBO ( Fixed Base Operator ) to have an A&P have a look at it. And since it is more then likely constructed of mostly composite materials, there are probably no A&P's who can repair it. They will just ground it and tell you to call the factory.

Trust me, I like the idea, I think it is very cool, but as presented there are a whole boatload of problems that will have to be overcome. I much prefer the older idea of a car that you attach the flying part to, then take off to your destination. When you get there, the flying part detaches and is stored until you return to fly back to where ever you came from.
