Orlando announces first vertiport for air taxis

Here they come, ready or not: Get used to the words “vertiport” and “air taxi,” because it’s happening faster than many thought. The FAA Re-Authorization Act, signed into law in October 2018 included five provisos we welcomed that address the airport and aircraft noise issue. But the same Act also approved what aircraft futurists wanted: accelerated development of both drone deliveries–backed by Amazon and Google–and what we used to call “AirUber,” i.e., mostly electrically-powered, small, vertical-takeoff air taxis known technically as  electric vertical take off and landing vehicles, or eVOTLs. In the end, aircraft may get quieter, but there are going to be lot more of them buzzing around.

Andrew J. Hawkins, writing in The Verge, describes a deal between the Orlando city council and the richly funded German start-up company Lilium, which has launched and begun testing its 5-passenger eVOTL. Clearly, there’s a long way to go, and as Hawkins points out there are at least 100 companies actively competing in this exciting new eVOTL space. But the vast majority of these companies are in Europe and China, not the U.S. Why? Because the FAA has been busy protecting Boeing’s back and preventing development of these next-gen aircraft here.

No Matter. Let the Europeans and Chinese get a head start building quiet, electric or hydrogen aircraft. The greatest driver of innovation in the U.S. has always been outside competition—other people beating us at the innovation game. The first computers were built and used in the UK. The first airplanes and rockets were used in warfare by Germany. The first satellite was launched by Russia. So if the world is going to get quiet, non-petro-fueled next-gen aircraft, others will get there first. It’s an old story. But this time, we need Congress and a well-organized, national constituency to stand up and demand that drone makers and eVOTL companies like Lilium explicitly address the noise problem. Otherwise, we may hear them flying over our houses and backyards. We need a say in the process before they land on these shores. That’s what the National Quiet Skies Coalition and the 50 members of the Congressional Quiet Skies Caucus are supposed to be doing.

We need to push them. Now. Get ready.

Electric air taxis may be exciting, but are they silent?

You have to watch this very cool video on electric air taxis. It all seems very exciting, but why don’t we hear them in action?

As you may remember, I voiced my concern about two new sources of sky borne noise that were spurred by the 2018 signing of the FAA Re-Authorization Act: (1) the imminent appearance of drone-delivery services in our neighborhoods, and (2) the growing interest in all-electric vertical take off & landing air taxis. Some thought this was pure hype from Uber—an attempt to pump up their stock before their IPO awhile back. But there’s actually quite a bit of investment in technology for small, short-hop, eVTOL aircraft.

The idea’s been out there for a lifetime that small aircraft could be wheeled out of our garages, leap straight up into the air and whisk us off to…someplace besides a crowded freeway. Will regulators shut it down? Unlikely. In fact, they’re actively encouraging development of eVTOL aircraft, particularly in Europe, where, as you likely know, they pay much more attention to community noise than we do here in the U.S.

But what about the noise—not to mention the air accidents—from the burgeoning, uncontrolled growth of drone delivery services and air taxis? Yes, they’re electrically propelled, but they’re not silent.

Who cares about this? It’s time for the Congressional Quiet Skies Caucus to re-convene and get back to work. They got the FAA Re-Authorization done (that took six years), but now it’s creating new problems that nobody seems to be thinking about.
