We Corrected the Federal Heliport Record. Six Times, Carefully.
In June we showed that the registry gap has a paper trail: hundreds of hospital helipads with federal airspace paperwork on file and no registration. This piece is what happened when we turned the same archive on the pads the registry does know about. Matching 483,006 FAA airspace case files against the facility registry produced 746 facilities where the case and the registry describe the same landing area but disagree about where it is. We adjudicated them. Six were registry errors, every one a hospital helipad whose federal coordinate sits 3,700 to 7,800 feet from the hospital it serves while the FAA's own case file places the pad within a few hundred feet. We corrected all six, and we preserved the FAA's original coordinate beside each correction, so the record of the error survives the fix. Then the honest half: when we took the strongest of the remaining conflicts into satellite adjudication, the registry won 13 of 14. The federal record is better than the noise suggests, and its errors are real, specific, and now on a watch list that will notice if the FAA ever fixes them.

Emergency Landing for eVTOL: The Infrastructure That Doesn't Exist
The emergency is a when, not an if. When it comes, an eVTOL needs somewhere to land, and the infrastructure for that mostly does not exist. We modeled it two ways on a real flight, JFK to Manhattan. First, reach: in a total power loss at 1500 feet, a helicopter can glide to a safe landing site over roughly 9 percent of the route, an eVTOL with wings over roughly 5 percent, and a multirotor over close to none. Then, usability: of 5,594 measured U.S. helipads, only about 30 percent are large enough to take a typical eVTOL as they exist today, and that is before the load bearing and obstruction gates that usually bind. Reach times usability means the usable emergency landing coverage for an eVTOL on a real corridor barely exists. This is not a glide circle problem. It is a whole system gap, and it is measurable now, before routes are declared operable.

The Registry Gap Has a Paper Trail
Earlier this month we reported that more than 1,100 hospital helipads operate in the United States with no FAA registration. The finding came from cross referencing two public datasets, and it left one question open: does the FAA simply not know these pads exist? We can now answer that for a quarter of them. We ingested the FAA's full archive of airspace case files, 483,006 cases reaching back decades, and matched every landing area case against the facility registry. For 284 of those unregistered hospital helipads, the FAA has its own paperwork on file: an aeronautical study, conducted and determined, at that exact location. The registry gap is not an awareness problem. It is a reconciliation problem inside the federal record itself.

Permission Isn't Readiness: The v2.0 Market Readiness Score
AirIndex has moved its 25-market readiness score to a new methodology, v2.0. Where v1.3 weighted regulatory permission at roughly 45% of the score and treated infrastructure and operators as present/absent flags, v2.0 rebalances around four co-equal pillars — regulatory authority, demand, landing capacity, and operator commitment — plus two modulators, momentum and operability. It now scores whether a market is permitted, demanded, landable, and being committed to, all at once. The result is more conservative and, we believe, more honest: no U.S. metro currently clears the ADVANCED tier, and Los Angeles leads. The full methodology is published, and every score change is explained on the market itself.

The State of the U.S. Heliport Record
The FAA's Airport Master Record is the authoritative account of where the nation's helicopters — and soon eVTOL aircraft — can land. We checked it against independent public datasets and found four systematic gaps. The record is almost never independently inspected (98.5% of U.S. heliports are owner-self-reported). It is incomplete: 1,121 hospital helipads have no FAA heliport on file within a nautical mile. It is stale, with pads that moved to rooftops while the record updated only in part. And it misplaces facilities — one Nashville heliport has been plotted 48.5 nautical miles from its true location since 1979. Every finding is reproducible from public sources, and the implications reach aviation safety, insurance underwriting, and the coming advanced-air-mobility build-out.

Pulse #19 — The registry lists thirty aircraft; the sky has seen seventeen
A sweep of public flight tracking records against the federal registry finds only seventeen of the thirty registered US eVTOL airframes have ever been seen flying: Beta crosses Vermont nearly every day and Joby reaches Dubai, while Wisk flies a confirmed test program that has never appeared on a public tracker.

Pulse #18 — The aircraft are at Oshkosh; twelve markets have no operator
With the industry gathered at Oshkosh, the board held flat and Los Angeles kept the lead at 72, while the operator presence reading came in at zero for twelve of the twenty five tracked markets: aircraft on display, but no operator on the ground in nearly half the map.

Pulse #17 — Not every “AAM law” is a law
A read of every advanced air mobility measure by instrument type finds the enacted column dominated by non-binding resolutions: Florida's H1093 vertiport statute is the clearest binding law of the cycle, while Arizona's bills to create and fund an AAM office both failed.
