Flying Car Passes First Flight Test

waderoush writes "Terrafugia — the Massachusetts company building a 'roadable aircraft' (that's flying car to you and me) — revealed at a press conference Wednesday that the Transition vehicle has been taken aloft for its maiden flight. The craft, which can fly up to 460 miles at 115 mph and then fold up its wings for 65-mph highway driving, was the subject of two hotly debated Slashdot posts on May 8 and May 13 of last year. The company said the first flight took place in Plattsburgh, NY; retired Air Force Colonel Phil Meteer was at the controls."

Nifty idea, but marginally too heavy

[Jay Maynard]

The video voice-over says that the Terrafugia's empty weight is 890 pounds. With a maximum gross weight of 1320 pounds set by the Light Sport AIrcraft rules, this leaves a useful load of just 430 pounds. Gasoline weighs 6 pounds per gallon. With two real people aboard, it won't have much range...

Every time I turn around I see another "flying car" that just can't get off the ground financially or technically.

This one could possibly be different, but I'm just not holding my breath.

I think it's a waste of time. The logistics involved with actually having a non-trivial number of these things up in the air over urban areas without mass casualties are just too difficult.

I reckon for flying personal vehicles to be actually feasible you need anti-gravity, a portal powersource capable of powering said anti-gravity-device, and some sort of master control network capable of automating and coordinating all such vehicles in the air to ensure they don't collide (among other things). So I would say the likelihood of personal air vehicles becoming feasible is rather slim at the moment.

Autonomous flight is an easier problem to solve

[GPS Pilot]

Everyone worries that the skies will become a deathtrap when flying cars, driven by people without pilots' licenses, hit the market. But the collision-avoidance solution is simple if they're all flying autonomously. In 2009, it's trivial for inexpensive consumer devices to communicate with each other wirelessly. Similarly, flying cars need to broadcast their positions and velocities to all other aircraft within a few km radius (via WiMAX or similar technology).

Then, all it takes are some simple "right of way" rules and a small amount of computing power to compute the slight course adjustments needed to avoid collisions, or even to avoid intersecting another aircraft's wake vortices. This will also eliminate "air lanes," and the fear of them becoming saturated with traffic. All aircraft will simply fly the shortest point-to-point great circle route, except when the computer tells it to deviate to avoid another aircraft, another aircraft's wake vortices, a region of bad weather, or an ADIZ.

Because three-dimensional airspace is so vast, it will be able to accommodate exponentially more traffic than the current "air lanes" concept.

Autonomous flight is a much easier problem to solve than autonomous ground vehicles. A large but simple database will allow the aircraft to avoid obstacles like mountains and tall structures. An autonomous ground vehicle, on the other hand, would need to tackle machine vision problems like discriminating between an actual pedestrian and a picture of human on a bus-stop advertisement.

In my case, I have a place to store an aircraft in a local home, and on my vacation property. I have a house in upstate NY which I would like to go to, but it is a 6-7 hour drive from my current location.

The ability to store this thing in my home garage, drive it to a local airport, fuel, and then fly to NY would be wonderful. I could land in a podunk airport, and drive the last 3 miles to my vacation home and store it in my garage there. I'm not too keen on arranging to park an aircraft at a field and pay a fee to do so when I could have the option of storing it in my own climate controlled garage (would it be a hangar then?)

If they can get it down to the sport craft limitations, this thing would be awesome and I'd buy one in a heartbeat.
