Joby Aviation had, by late 2025, flown over 850 test flights and logged more than 9,000 miles of testing across three continents — by a wide margin the most advanced flight-test campaign of any eVTOL developer anywhere. In November 2025 it received Type Inspection Authorization, entering Stage 4 of the FAA's five-stage certification process. Read quickly, that sounds like a company on the verge of certification. It isn't, and the distance between "entering Stage 4" and "holding a type certificate" is the whole argument of this piece, made originally by analyst Bright Ibeawuchi at Low Altitude Economy in February 2026 and borne out, almost exactly, by how Joby's own disclosures played out through the rest of the year.

Stage 4 is where the bulk of certification flight testing happens. Stage 5 is where that testing's output — thousands of pages of flight data, analyses and conformity findings — gets formally processed, reviewed and approved by the regulator. That review does not run on the manufacturer's clock. Even a company with Joby's test tempo and roughly $800 million in cash on hand, which is a strong balance sheet for this industry, cannot buy its way through a government review process any faster than the FAA's own staffing and precedent allow. Analyst estimates circulating alongside Joby's TIA milestone put the odds of full U.S. type certification by mid-2027 — not 2026 — at somewhere between 20 and 30%.

China's CAAC certified EHang's EH216-S in 31 months. The FAA's own timeline for a comparable new aircraft category runs five to seven years.

Certification odds, as estimated

Joby type cert. by mid-2027
20–30%
Archer realistic target
2028+
Multiple simultaneous certs.
<15%
CAAC (EHang), start→cert.
31 months
FAA, comparable category
5–7 years

Archer Aviation's position was, and largely remains, a year or so behind Joby's: the company was expected to initiate its own TIA process by the end of 2026, which puts a realistic certification target at 2028 or later rather than anywhere inside this year. Taken together, the analysis put the probability of multiple U.S. manufacturers certifying simultaneously — the scenario implied by a lot of "the eVTOL era arrives in 2026" coverage — at under 15%.

The regulatory gap is only part of the story; the infrastructure gap is arguably the more durable constraint. Vertiports purpose-built for eVTOL operations remain scarce everywhere outside a handful of showcase projects — Dubai's facility, targeted for the first quarter of 2026, was, at the time of writing, the closest thing globally to a purpose-built eVTOL terminal, and U.S. urban markets have nothing comparable in density. Insurance frameworks for autonomous and semi-autonomous passenger aircraft remain fragmented, with no meaningful actuarial history to price risk against. And urban air-traffic-management systems capable of handling routine low-altitude passenger traffic at scale remain unproven commercially, anywhere.

None of this is a case against the technology, which by 2026 has repeatedly demonstrated itself in the air — Vertical Aerospace's own two-way transition flight, reported elsewhere on this site, is one more example of hardware outrunning the paperwork around it. It's a case against treating a regulatory process built for an entirely new aircraft category, under the FAA's 2024 Special Federal Aviation Regulation for powered-lift aircraft, as something that compresses to meet a marketing calendar. China's own experience is the useful contrast rather than a simple point of comparison: the CAAC took roughly 31 months to certify EHang's EH216-S, against an FAA timeline this analysis estimates at five to seven years for a broadly comparable aircraft category. Different regulators, different risk tolerances, different institutional starting points — and, as a result, very different years in which "certified" actually arrives.

The honest version of the 2026 story is not that the eVTOL industry failed to deliver. It's that 2026 was never a serious certification deadline to begin with — it was a year by which test flights, partnerships, defence spin-offs and funding rounds were always going to be the real news, with the FAA's signature arriving later, on its own schedule, regardless of how many of those other milestones land first.
