"Holding Short, Highway 35"?

If you listened all the way to about 4:10 in the video from my first post in the "Flying Cars" series, you may have heard Richard Gersh talk about one of the challenges facing his company's first production flying car: due to the regulatory separation between cars and planes, the Transition really has to live up to its name to go from byway to skyway.  The switch from car to plane doesn't take long, but it does require the pilot (not driver) to stop the vehicle, turn off the engine, and get out to do a normal pre-flight check.  As he says in the video, you need to find an actual runway to go airborne anywhere but Montana or Alaska.  Re-read that last sentence.  The vehicle doesn't fly that much faster than it drives, but claiming it could fly its way over a traffic jam in those two states was what really perked up my legal antennae.  I wondered where Gersh had gotten that idea, and Terrafugia was kind enough to give me a few minutes to ask him about it. *4

Gersh was quick to point out that this is not an intended SOP for this bird.  The switch has to happen on an airfield, and the wings should never be down on a roadway except in an emergency.  The main uses for driving the Transition will be getting to and from the airport, dodging inclement weather, and getting bizarre looks from other drivers.  The first two are no joke: hangar fees are high and climbing, and a quarter of all weather-related accidents are fatal.  Ok, enough with the disclaimer - let's get to the fun stuff.

On the state side of things, Gersh told me the bit about Alaska and Montana was something they'd been told anecdotally and wasn't too sure about the regs.  It's entirely plausible that the bush pilot capitol of the US and the only State with (at one time) no speed limit on some of its roads would be open to that kind of thing, but I'm slowly developing a need for written rules.  I dug into this problem a bit and found that many of the state and local governments that regulate most of the roadways in this country have actually had the foresight to deal with whether they may be used as runways.  Click here for a table with the statutes I've been able to compile so far, and feel free to shoot me an email if you know about regulations I've missed or mischaracterized in your state.  They fall into roughly four categories: free use (within local rules), use by permission, local ordinances authorized, or no use at all.  The "by permission" category leads the race right now.  States have gotten pretty creative in highway/runway enforcement on a couple of occasions, like the time a Minnesota State Trooper found a pilot and landscaper's aircraft intentionally parked on a roadside, advised the pilot that he would be cited for driving an overly wide vehicle, and allowed him to take off using the highway as a runway. (*3) Regardless, even states like Montana and Alaska don't seem to have put these rules to much use yet.  Props to those states that have seen this coming - all eyes will be on them to see how they handle tomorrow when it arrives.

Shown here over a perfectly tolerable commute.
On the federal side, when it comes to the airspace necessary for highway takeoffs and landings, the FAA has been a bit vague.  In a response letter to Jeff Buckholz of Buckholz Traffic, the agency seemed to indicate (*1) that it would treat the Transition just like any other "device that is used or intended to be used for flight in the air" in that takeoffs and landings would be governed by 14 C.F.R. 91.13 and 91.119.  As with any aircraft, pilots would be prohibited from operating the Transition "in a careless or reckless manner so as to endanger the life or property of another" under § 91.13.  § 91.119 prescribes minimum safe flight altitudes, and the combination of those sections would presumably ban my hypothetical traffic dodging except in emergency landing situations. (*2) The FARs also define an Airport as "an area of land or water that is used or intended to be used for the landing and takeoff of aircraft," so the FAA would presumably treat a state-owned roadway sanctioned for use as a runway (and lying under uncontrolled airspace) like any other uncontrolled grass strip.  I haven't yet looked into how recreational use statutes would fit into this framework, but I'll be doing an article on those in the next month or two.  Stay tuned.


In short, this is all uncharted water and it's tough to know how it will all shake out.  A few states seem to be open to the possibility of using their roadways as runways, and the FAA has not done anything to indicate they couldn't.  This will certainly be a fun field to watch.

All that said, Terrafugia's next project, the TF-X, blows these regulatory questions out of the water.  As Gersh said in the interview, this really is a Jetson-like machine, and their aspirations for its operation are nothing short of science fiction.

Hart, 6 N.T.S.B. 899 (1988) (finding that the minimum-altitude-flight regulations are violated when an aircraft descends in order to land at non-suitable landing site); Administrator v. Mollis, 2 N.T.S.B. 43 (1973) (finding that a pilot violated the pertinent regulations when he made a decision to land on a highway, which ultimately resulted in his aircraft colliding with a truck).
