How the AAM Sector Talks About Milestones — and Why It Needs More Accuracy
Spend thirty minutes reading practically any Advanced Air Mobility (AAM) press release from the past ninety days and a pattern emerges. The language is confident. The milestones are real. And the gap between what the words imply and what the milestone actually represents is, in almost every case, wide enough to drive a Midnight aircraft through.
“Commercial flights begin.” “Certification to operate commercial airline.” “First certified AAM technology.” These are not technically inaccurate. But they are something more consequential: a shared industry vocabulary that compresses regulatory and commercial reality into investor-friendly language — and in doing so, systematically misleads the people most dependent on accurate information.
This is not an analysis of any single company. Every major AAM OEM does this and has genuine reasons for doing so. Valuations depend on it. Investor calendars require it. Competitive positioning demands it. The problem is structural, not individual.
The AAM sector has developed a shared vocabulary of implied imminence. Every major OEM uses it. The readers who don’t know the code are the ones who pay the price.
The Shared Vocabulary — and What It Means
Before examining individual OEMs, it is worth establishing the lexicon. The same phrases appear across company press releases with remarkable consistency. Understanding each term’s technical meaning versus its implied meaning is the baseline for reading the sector accurately.
“Commercial flights begin” — Almost always describes test flights under a Type Inspection Authorization (TIA), a regulatory permission to fly a specific aircraft for data-gathering purposes. A TIA is not a type certificate. It is not authorization for revenue-generating passenger operations. It is a milestone on the path to certification, not the destination.
“Operations launching [season/year]” — Typically describes eIPP (eVTOL Integration Pilot Program) participation or pre-certification demonstration operations. The FAA’s eIPP program is a structured, supervised data-gathering framework with strict OTA parameters. It is not a commercial ticket portal.
“FAA Certification” — This is the most misleading category, because it can be technically accurate while describing something entirely different from what readers assume. Operator certificates (Part 135, 141, 145) certify the airline entity, the flight school, and the maintenance organization. They say nothing about whether the aircraft itself is certified to carry passengers. Calling these “FAA Certification” is accurate in the narrowest sense and misleading in every practical sense.
“Letter of Intent” / “LOI” — A non-binding expression of interest. An LOI generates no revenue and commits no capital. In an industry where LOIs are routinely announced at trade shows, they have become the single most inflated form of communication in the sector.
“First certified AAM technology” — A component-level certification (a propeller, an engine, a battery system) framed as program-level progress. Technically true. Rhetorically, it positions a Part 35 propeller certificate as evidence that an aircraft is close to certified.
The Evidence: OEM by OEM
The following case studies are drawn from actual published press releases. Each illustrates a specific compression technique — not dishonesty, but a deliberate gap between what happened and what a reader is invited to conclude.
Joby Aviation
| “Joby Caps Year of Flight, Demonstrating Global Commercial Readiness and Operational Momentum Towards FAA Certification” Joby IR, December 14, 2025 | |
| ACTUAL | Extensive flight testing and demonstrations across multiple markets; still working toward FAA type certification. |
| THE GAP | The title itself welds “global commercial readiness” to “operational momentum towards FAA certification,” inviting readers to treat demo flight capability as a proxy for being close to commercial operation. These are categorically different things. |
| “Joby Completes Submission of Stage Three Certification Plans to the FAA” Joby Aviation, January 28, 2026 | |
| ACTUAL | Submission of all certification plans — Stage 3 of 5 in the FAA’s type certification process. No TIA. No type certificate. |
| THE GAP | The release pairs an internal process milestone (Stage 3 plan submission) with a specific in-service date, inviting readers to see type certification and commercial launch as a single, linear track rather than a five-stage process where Stage 3 means three stages remain. |
Joby is the sector leader and its underlying progress is real. These examples illustrate how even genuine, significant milestones are framed to compress the remaining distance to commercial service.
Archer Aviation
| “Archer Receives FAA Certification to Begin Operating Commercial Airline” Business Wire (Archer), June 4, 2024 | |
| ACTUAL | Receipt of Part 135 Air Carrier & Operator Certificate for Archer Air, using conventional aircraft. Midnight has not received its type certificate. |
| THE GAP | The headline “Receives FAA Certification to Begin Operating Commercial Airline” describes an operator certificate — a certificate for the airline entity, not the aircraft. To any non-specialist, it reads as confirmation that Archer’s eVTOL is certified for commercial airline service. It is not. |
| “Archer Receives FAA Certification To Launch Its Pilot Training Academy” Archer Investor Relations, February 17, 2025 | |
| ACTUAL | Part 141 flight school approval. Midnight still awaiting type certificate. |
| THE GAP | The release states Archer has now received “the third certificate required by the FAA for it to launch air taxi operations when Midnight receives its Type Certification.” Bundling Part 135, 141, and 145 operator certificates into “certificates required to launch” systematically obscures that the type certificate — the one that actually authorizes the aircraft to carry passengers — remains the central and still-unresolved requirement. |
The Archer examples are among the most instructive in the sector because the compression is structural: an entire narrative of “FAA certification progress” is built from certificates that certify the airline operator, not the aircraft. The headline language is technically defensible. The inference it produces is less so.
BETA Technologies
| “BETA Technologies Announces Third Quarter 2025 Results: First Certified AAM Technology” BETA Technologies Investor Relations, December 3, 2025 | |
| ACTUAL | A pusher propeller certified under FAA Part 35. Working toward Part 33 type certification for the H500A electric engine. Special Airworthiness Certificate for first production ALIA VTOL. |
| THE GAP | Positioning a certified propeller as “first certified AAM technology” rhetorically elevates a component-level Part 35 type certificate into something approaching program-level aircraft certification. The phrase will register to most readers as “the aircraft is certified.” It is not yet. |
BETA’s example is subtler than Archer’s — the language is more precise on inspection — but the highlight framing does the same work: it positions partial, component-level progress as a program milestone that signals commercial proximity.
Vertical Aerospace
| “Vertical announces further certification progress — targeting entry into service in 2025” Vertical Aerospace, April 2022 | |
| ACTUAL | Certification basis proposal submitted to UK CAA; concurrent EASA validation planned. Still negotiating certification basis — well before TIA or detailed compliance findings. |
| THE GAP | “Programme is progressing rapidly as it targets entry into service in 2025” places early regulatory engagement — submitting a certification basis proposal — in the same narrative frame as an approaching commercial launch. Vertical filed for insolvency in December 2024, never having received a type certificate. The 2025 target was built on a foundation that had not yet been laid. |
The Vertical Aerospace case is the sector’s clearest cautionary data point. The distance between “progressing rapidly” press release language and eventual insolvency was approximately 32 months. The compression of early regulatory engagement into near-commercial-readiness framing contributed to a capital narrative that did not survive contact with the actual certification timeline.
Wisk Aero
| “Wisk and Texas Selected by White House to Lead the Safe Introduction of Autonomous Air Taxi Flight” Wisk Aero, March 9, 2026 | |
| ACTUAL | Selection into the FAA’s eVTOL Integration Pilot Program (eIPP). G-1 issue paper accepted. No type certificate. No production certificate. No air carrier certificate. |
| THE GAP | The release speaks of “a clear path to begin operations” and “the safe introduction of autonomous air taxis.” eIPP selection is a genuine regulatory milestone. But framing it as “a clear path to begin operations” leaves Type, Production, and Air Carrier certification as implicit background detail rather than foregrounding that none of the three commercial approvals are yet complete. |
| “Wisk Aero reveals its market-ready, self-flying air taxi” TechCrunch (Wisk PR), October 2022 | |
| ACTUAL | Generation 6 autonomous air taxi unveiled. Type, production, and air carrier certifications all still ahead. |
| THE GAP | Wisk’s own framing calls the Gen-6 design “go-to-market” and “market-ready” while noting certifications remain ahead — a rare case of relative transparency. But “market-ready” plus autonomy framing can easily be read by a lay audience as “certification is mostly a formality.” The word “ready” is doing asymmetric work. |
Wisk is worth noting for contrast as well as caution. Its 2022 press releases were more explicit than most peers about the three-step certification stack. That transparency has since been partially diluted by eIPP-era “path to operations” language.
Credibility Framework: Five OEMs at a Glance
The following table consolidates the documented examples into a consistent analytical framework. Credibility gap levels reflect the distance between press release language and operational reality — not an assessment of the company’s technology or long-term viability.
| OEM | Claim Type | Actual Status | Gap Level | What to Watch |
| Joby | “Commercial readiness” + cert milestone | Stage 4 ~80% co. / 73% FAA; TIA flights; no type cert | MODERATE | FAA pilot flights; Stage 5 entry |
| Archer | “FAA Certification” for ops-side certificates | Part 135/141/145 certs for operator entity; Midnight has no type cert | HIGH | Type cert progress; litigation posture |
| BETA | “First Certified AAM Technology” | Part 35 propeller cert; Part 33 engine cert in progress; Special Airworthiness only | MODERATE | Part 33 engine cert date; Part 135 filing |
| Vertical | “Progressing rapidly” toward 2025 EIS | Cert basis submitted to CAA; EASA validation planned; early regulatory engagement only | HIGH | Company entered insolvency; cautionary case |
| Wisk | “Clear path to begin operations” via eIPP | G-1 issue paper accepted; eIPP selected; no type cert, no production cert, no air carrier cert | MODERATE | Boeing ecosystem post-737 reset; FAA autonomous framework |
The Certification Ladder Nobody Draws
The FAA’s type certification process for a novel aircraft category runs through five distinct stages. Virtually no mainstream financial or general media coverage maps OEM progress against this ladder consistently. The only OEM commercial certification roadmaps I have seen were at special events, all paid-for attendees, and not on public press releases, if ever. The result: readers receive milestone announcements without the context needed to assess what a milestone actually means. Investors may get 66% of the industry snapshot and make decisions based on that.
To approve an eVTOL for commercial service, the FAA must issue three separate approvals: type certification for the aircraft design, production certification for the manufacturing process, and operational authorization for the service itself. All three must be in hand before a company can legally carry paying passengers in U.S. airspace.
The operator certificates that Archer has accumulated — Part 135, 141, 145 — are real and necessary. They certify the airline entity, the training organization, and the maintenance function. But they do not certify the Midnight eVTOL aircraft. Until it has a type certificate, those three certificates are preparation for the final certification.
The finish line is three finish lines. Press releases routinely describe reaching the first as though the race is won.
Industry analysts have pushed projections for eVTOL commercial entry into service to at least mid-2027. For Joby, Wall Street projects revenue growing from approximately $113 million in 2026 — mostly from the acquired Blade helicopter business — to $2.25 billion by 2030. That gap is not pessimism. It is the certification ladder, priced in.
Why OEMs Do This — and the Disservice
It would be unfair to describe AAM press release language as dishonest. The companies involved have built extraordinary technology, demonstrated resilience, and navigated a grueling regulatory environment. Many of them are still in the AAM industry far outpacing that of conventional aerospace startups.
The incentive structure that produces compressed language is entirely understandable and widely used in almost all industries. Public valuations depend on sustained investor confidence sparked by public excitement. Competitive dynamics require each company to signal progress relative to peers. Trade media rewards confident declarations over nuanced qualifications. It is also noteworthy to understand that the technical distinctions between a Part 135 operator certificate and a type certificate are genuinely difficult to communicate in a headline. This is something I have been doing for 20 years, distilling complex topics for public understanding. It isn’t easy, by any stretch of the imagination.
However, none of that makes the pattern acceptable — because the readers who pay the price for compressed language are not the investor relations teams. They are the capital allocators modeling AAM exposure, the infrastructure developers making construction timing decisions, the municipal governments committing public resources to vertiport development, and the general public forming expectations about when this technology will actually be available.
The electric vehicle industry offers a direct precedent. Over-claiming on range, charging infrastructure, and timeline during EV’s early adoption phase contributed to a consumer backlash that slowed adoption in exactly the market segments where honest communication would have built durable confidence. AAM is at a comparable inflection point.
The EV industry learned this the hard way. The AAM sector has the opportunity to learn it a different way — before the credibility gap compounds into an adoption problem.
A Proposed Standard: The Credibility Timeline Framework
What would better practice look like? Not less communication — more precise communication. A proposed standard:
- State the certification stage explicitly. Every announcement should name the current stage of the FAA’s five-stage process and where the company sits within it.
- Distinguish aircraft certification from operator certification. Part 135, 141, and 145 certificates are operator certificates. Describe them as such. Do not headline them as “FAA Certification” without specifying what has and has not been certified.
- Distinguish TIA flights from commercial operations. If the flight being described is a test flight under regulatory oversight, say so. If it is a commercial passenger operation, say so.
- Separate eIPP from commercial launch. Any announcement involving eIPP participation should include a plain-language explanation: eIPP is a supervised data-gathering program, not a commercial service launch.
- Identify LOIs as LOIs. Letters of intent should be described with their binding status explicitly stated — not headlined as partnerships or deals.
- Name the remaining approvals. Any significant milestone announcement should identify which of the three required approvals (type, production, operational) has or has not yet been achieved.
The Questions That Should Follow Every Announcement
Until the sector adopts a more precise communication standard, readers and analysts can apply a consistent set of questions to any AAM press release:
- Which of the five FAA certification stages is this company currently in, and at what percentage of completion on both the company and FAA sides? Show the roadmap.
- Is this a TIA flight, an eIPP flight, or a commercially authorized operation? Who is paying for the seat, and under what legal framework?
- Is this an operator certificate (Part 135/141/145) or an aircraft type certificate? These are different things. Which one is being announced?
- Is this announcement based on a signed contract, a letter of intent, or a memorandum of understanding? What are the binding terms?
- Has physical construction begun at the referenced infrastructure location? Is there a municipal planning record, permit filing, or groundbreaking confirmation?
- Which of the three required approvals — type, production, operational — does this company currently hold, and which remain outstanding?
These questions will not always produce flattering answers, but honest ones investors can gauge and fund the right companies to get the industry running sooner than later. They will almost always produce accurate ones. And accurate answers are, for capital allocators and infrastructure developers making long-duration decisions, worth considerably more than enthusiastic ones.
The certification roadmap is the first question. The infrastructure question is the second — and the one the sector has systematically avoided answering. If 95% or more of capital has flowed to vehicle makers, the industry has funded the aircraft without funding the places they need to land, the energy systems they need to charge, and the intelligence layer that governs it all. That gap is where the next analysis begins.
Flying is not the same as certified to fly. Operations launching is not the same as operations open. The sector that closes that language gap will be the sector that earns lasting public confidence.
