UAM Market Pulse — Issue 19

The Registry Lists Thirty Aircraft. The Sky Has Seen Seventeen.

Every week this digest reads the market board. This week we read the sky. The federal aircraft registry lists thirty electric air taxi airframes registered to seven American manufacturers, and paper is where most of this industry gets measured: registrations, filings, certification targets, announcements. So we swept public flight tracking records for every one of those thirty tails and asked a simpler question than any press release answers. How many of these aircraft has the public record actually seen fly? The answer is seventeen. The other thirteen have no public track at all, and the reasons why split into three very different stories.

What the Sky Shows

Three tiers, drawn from a sweep of public flight tracking data against the federal registry. Read them top to bottom. The distance between the paper fleet and the observed fleet is the state of the industry.

SEEN FLYING · 17 OF 30 AIRFRAMES

Joby, Beta, Archer. Joby tails show up the way a serious flight test campaign should: steady local work over Marina, California, one airframe tracked into Kennedy this spring, another flying in Dubai. Archer’s two Midnight aircraft broadcast from Salinas as recently as this past Monday. Beta operates the most transparent fleet in the industry. Its hover capable aircraft crosses between Burlington, Vermont and Plattsburgh, New York nearly every day, and its conventional takeoff sister ships range farther: one has been working in the United Kingdom, another hopped between Hawaiian islands earlier this month.

FLYING, BUT NOT WHERE THE PUBLIC CAN SEE

Wisk. The company’s two autonomous aircraft have been in flight testing since last December, by the company’s own account. Neither has ever appeared on a public tracker. That is legal, and it may well be deliberate, but it makes Wisk the one active American flight test program the public record cannot watch. One Joby tail sits in this tier for a different reason: its owner filed the federal privacy request that removes an aircraft from public tracking displays.

NO EVIDENCE OF FLIGHT

The rest of the registry is quiet for reasons the registry itself will not tell you. Two tail numbers are reserved for aircraft that have not flown. Two belong to a company that has effectively wound down. One belongs to a program that paused last year and is only now discussing a restart. One is a single seat ultralight. The remainder are earlier prototypes and quiet airframes that may simply be between campaigns. The registry keeps every one of them on the books, which is exactly why reading the paper alone tells you so little about who is actually flying.

Flight Is the One Metric That Cannot Be Press Released

This industry measures itself in announcements. Orders, partnerships, certification timelines, market entries. All of it is real and all of it is paper. A flight is a different kind of fact. It happened or it did not, it left a track or it did not, and no communications team can adjust it afterward. Even the registry itself was never built to describe what these aircraft do. The federal speed field reads zero for every one of the thirty.

The honest caveat runs in one direction. A missing track never proves a missing flight. Experimental aircraft can legally fly without the broadcast equipment public trackers depend on, and owners can ask to be removed from public displays. Wisk is flying. The record simply cannot see it. So seventeen is a floor, not a census, and we treat it that way. What the floor already shows is worth the look. Beta flies like an operator, the same route, nearly every day. Joby flies like a company preparing markets, from California to New York to Dubai. Archer flies like a test campaign. And a fleet this small already contains one program the public cannot observe at all.

The gap between thirty and seventeen is not a scandal. It is the measurement problem this industry has not solved. When the market wants to know how close electric air taxis really are, it counts announcements, because announcements are what there is to count. We think the better ledger is the sky, and this is the first of what will become a standing reading of it.
