# eVTOL: From Letters of Intent to Binding Orders
_Announced commitments versus firm orders_

## AI research use contract

- Treat this file as source-grounded context, not a live database. Quote `source_ref` and `data_as_of` when using numbers.
- Separate `FACT`, `ESTIMATE`, `FORECAST`, `TARGET`, and `INFERENCE`. If a row basis is unclear, say it is unclear.
- Prefer T1/T2 sources for hard facts; use T3/T4 sources as context that should be checked before money, legal, medical, operational, or policy decisions.
- Keep answer structure clean: first say what the data says, then what you infer, then what would change the conclusion.

## Research upgrade checklist

- Never aggregate letters of intent with binding orders; commitment quality is the whole story here.
- Note where an order book is reported in dollars rather than units — the two are not comparable.
- Treat certification dates as stated targets, not forecasts; this sector has slipped repeatedly.
- Add a prompt on unit economics and vertiport infrastructure, not just aircraft counts.

## TL;DR — index summary

Eve Air Mobility's commitments run toward 2,700 aircraft, but the overwhelming majority are letters of intent. In the week of 3 August 2026 Revo (Brazil) and AirX (Japan) each committed to up to 50 aircraft — the shift from LOI to firm order. The AirX deal covers two initial aircraft for delivery in 2029.

## What this index covers

Three series: announced order book by OEM, Eve binding orders, and stated FAA type-certification targets.

**Series in this index:**

- `order_book` — Aircraft under order or letter of intent by OEM.
- `binding_orders` — Firm commitments announced in August 2026.
- `certification` — Stated FAA type-certification target year.

**Entities tracked:** Eve Air Mobility, Archer, Joby, Revo, AirX.

## Key findings

- Eve commitments approach 2,700 aircraft, mostly LOIs (riotimes-eve-2700).
- Archer reports an order book above $6bn in value rather than a unit count — not directly comparable (datadeep-evtol-2026).
- Revo and AirX each committed to up to 50 aircraft in August 2026 (eve-airx).
- Joby and Archer target FAA type certification by end-2026 or early 2027 (aviationweek-bizav-aug2026).

## Evidence basis map

The free tables above show `source_ref` but not the row-level `value_basis`. This section mirrors the visible rows only, so AI tools can separate observed values from estimates, forecasts, targets, and derived values.

| series | row | source_ref | value_basis |
| --- | --- | --- | --- |
| order_book | oem=Eve Air Mobility; aircraft=2700 | riotimes-eve-2700 | Total commitments toward ~2,700 aircraft — overwhelmingly letters of intent, not binding orders |
| binding_orders | customer=Revo (Brazil); aircraft=50 | aviationweek-bizav-aug2026 | Binding order for up to 50 aircraft, week of Aug 3 2026 |
| binding_orders | customer=AirX (Japan); aircraft=50 | eve-airx | Second binding order with AirX for up to 50 aircraft; first two aircraft expected 2029 |
| certification | oem=Joby Aviation; target_year=2027 | datadeep-evtol-2026 | Targeting final FAA type certification by year-end 2026 / early 2027 |
| certification | oem=Archer Aviation; target_year=2027 | datadeep-evtol-2026 | Targeting final FAA type certification by year-end 2026 / early 2027 |

## The series (per-chart briefings)

### Announced commitments — hbar
**Direct answer:** Aircraft under order or letter of intent by OEM.
**Time bracket:** Aug 2026

| oem | aircraft | source_ref |
| --- | --- | --- |
| Eve Air Mobility | 2700 | riotimes-eve-2700 |

**Read:** Commitment quality varies sharply between these bars.
**Caveat:** LOIs are not binding orders and do not support revenue recognition. Archer's dollar-denominated book is not unit-comparable.

### Binding orders — bar
**Direct answer:** Firm commitments announced in August 2026.
**Time bracket:** Aug 2026

| customer | aircraft | source_ref |
| --- | --- | --- |
| Revo (Brazil) | 50 | aviationweek-bizav-aug2026 |
| AirX (Japan) | 50 | eve-airx |

**Read:** Binding does not mean near-term — AirX takes two aircraft in 2029.

### Certification targets — hbar
**Direct answer:** Stated FAA type-certification target year.
**Time bracket:** target

| oem | target_year | source_ref |
| --- | --- | --- |
| Joby Aviation | 2027 | datadeep-evtol-2026 |
| Archer Aviation | 2027 | datadeep-evtol-2026 |

**Read:** Stated targets, not forecasts.

## Cross-series synthesis — why this matters

Read order_book against binding_orders and the sector's central problem appears: a headline book of thousands resolves into firm commitments in the low hundreds. Read both against certification and the sequencing is clear — nothing converts to revenue before type certification, and every date on that chart is a target the industry has moved before.

## Entities & relationships

| Entity | What they do | Key stat | Relationship |
| --- | --- | --- | --- |
| Eve Air Mobility | Largest announced book | ~2,700 commitments, mostly LOI | The clearest LOI-vs-firm gap |
| Archer | Certification frontrunner | >$6bn order book by value | Reports in dollars, not units |
| Joby | Certification frontrunner | Targeting Dubai commercial launch | First-service candidate |

## Timeline of key events & decisions

- **w/c 3 Aug 2026** — Revo and AirX firm orders, up to 50 aircraft each → the LOI-to-binding transition
- **end-2026 / early-2027** — Stated FAA type-certification targets → the gate before any revenue
- **2029** — AirX first two aircraft due → shows the lag between binding and delivery

## Cross-industry ripple

- **Urban infrastructure:** Vertiport siting and power supply become prerequisites, not follow-ons. _(inference)_
- **Aviation insurance:** A new type with no service history has no loss record to price against. _(inference)_
- **Battery supply:** Aviation-grade cell demand competes with the automotive volumes in battery-pack-prices. _(inference)_

## Non-obvious reads (interpretation)

_This section is interpretation, not sourced fact — each item names the observation it is built on and a confidence level._

- **Observation:** A firm order for 2029 delivery sits alongside a 2026 certification target.
  **Read:** Even the binding commitments imply a multi-year gap between certification and meaningful delivery volume, so certification is a necessary but far from sufficient milestone for the revenue case. _(confidence: medium)_

## Glossary / key terms

- **LOI** — Letter of intent — a non-binding expression of purchase interest.
- **Type certification** — Regulatory approval of an aircraft design, required before commercial operation.
- **eVTOL** — Electric vertical take-off and landing aircraft.

## How to use this with AI

Paste this file into an LLM context window (or a RAG store) and ask cross-series questions. The tables carry a `source_ref` per row; the source registry below maps each ref to a named source and a trust tier.

### Suggested prompts (multi-series)

```text
Using order_book and binding_orders, estimate what share of announced eVTOL demand is contractually enforceable.
```

```text
Given certification, build a delivery-ramp scenario and state where it is most likely to slip.
```

## Caveats & what this index cannot answer

- Revenue, unit price, or margin.
- Whether stated certification targets will hold.
- Comparable unit counts for OEMs reporting order books in dollars.
- Estimates and forward targets are labelled in the working dataset; never read a labelled estimate or forecast as a settled figure.
- This is an observational data index, not investment, legal, or medical advice.

## Data freshness & methodology

- **Last updated:** 2026-08-11
- **Data as of:** 2026-08
- **What changed most recently:** Revo and AirX converted to firm orders in the week of 3 August 2026 — the sector's first clear LOI-to-binding shift.

**Methodology (as seeded):**

> The headline number in this sector is commitment volume, and it is
> badly overstated if letters of intent are counted as orders. Eve’s
> ~2,700-aircraft figure is total commitments, the large majority of
> which are LOIs. The separate "binding orders" chart isolates the
> firm commitments announced in the week of Aug 3, 2026.
> 
> Archer publishes an order book by VALUE (>$6bn) rather than by unit
> count, and Joby does not publish a comparable unit total, so neither
> appears on the unit chart. Converting a dollar book to units would
> require an assumed unit price — omitted per the binding rules.
> 
> CAVEAT: certification target years are OEM statements, not
> regulator commitments, and have slipped repeatedly across this
> sector. The Aug 2026 sourcing on the binding orders is thin — a
> single trade-press brief plus the OEM release.
> 
> Scout run: Trending_Candidates/2026-08-06.md. Re-verified 2026-08-10.
