Performance figures are attributed manufacturer targets or claims unless explicitly identified as demonstrated. Payload, weather, reserves, and aircraft configuration affect real-world performance. Figures may use different test assumptions.

Where it stands

Certification testing

Joby’s aircraft, commonly known as the S4, uses six tilting propellers and carries a pilot with four passengers. Its intended role is a booked transport service between landing sites, rather than a vehicle that can drive on public roads.

The program reported flights by its first FAA-conforming test aircraft in March 2026. Subsequent demonstrations placed the aircraft in New York and North Texas, making airport integration and route operations visible parts of development.

Joby combines aircraft development with plans for operations, customer booking partnerships and infrastructure. Published speed and range are manufacturer figures; they do not guarantee a particular route, payload or travel time.

Availability

Development aircraft; broad public electric air taxi service not established by the cited sources.

Certification & operating context

FAA type-certification work ongoing in cited 2026 updates; conforming aircraft in flight testing.

What to watch next

Formal certification results, local operating authorizations and an explicitly announced bookable electric service.
