It's illegal for it to go faster than 55 knots.
They're certifying this as a Part 103 Ultralight, and under the regulation, it: "Is not capable of more than 55 knots calibrated airspeed at full power in level flight." Since this is a multicopter with ostensibly some sensors, it's quite possible they're limiting this in software, but it is extremely disingenuous to say this can do 100 mph. It cannot, because that's illegal.
Additionally, the previous version of the Kitty Hawk Flyer, basically a decacopter with a seat, weighed 220 pounds, per reports. The new version of the Flyer has significantly more structure, and the weight limit for Part 103 ultralights is 254 pounds. I would hazard a guess that there's more than 34 pounds of chassis and fiberglass on the latest version. It's questionable if the 'floats' count toward that weight, in which case I would like to congratulate the Kitty Hawk team in engineering around the regulations.
But a Part 103 'flying car' is just about the dumbest idea ever. It can't be used to commute; you can call your local FSDO and confirm that yourself. You're also not going to fly it in San Francisco between Hunters Point, Pacifica, and San Mateo; there's an airport in the way. To say this is a 'flying car' is disingenuous and goes along with the SV philosophy of, 'screw laws and regulations, we're innovating'.
I honestly can't believe this got funding. I'm not surprised CNN is lapping it up; they're traditionally terrible with aviation-related news. I would guess that's why they were given the exclusive.
- jacobush 8y agoOkay, while I agree with it being extremely disingenuous to say it can do 100mph, I have to temper a bit... The world is larger than San Francisco and this thing or something like it could be useful in lots of other places in the world.
- scotty79 8y ago> "Is not capable of more than 55 knots calibrated airspeed at full power in level flight." Law is a funny thing. "Level flight" is used because if you go down then obviously you can go faster and it is assumed that when ascending you'd be slower. If you have software limiter that kicks in only when the flight is level then you can ascend 100mph and descend at 100mph and still be incapable of more than 55 knots in level flight. So legal.
- Shivatron 8y agoI read an awesome comment on HN the other day that I think applies here: something to the effect of, “some seem to think that the law is a simple robot that is easily bamboozled by specious arguments.” In other words, it’s probably unwise to think that going 100kts in a part 103 certified ultralight will meet with regulatory approval because the VSI reads +1 fpm.
