Fold the aircraft into the journey after landing.
An aircraft normally ends its journey at an airfield. AirCar explores a different handover: land, retract its flight surfaces and continue on the road.
SK SlovakiaIn practice. Klein Vision demonstrated a 35-minute flight from Nitra to Bratislava in June 2021. The flown prototype received a Slovak Certificate of Airworthiness in January 2022.
What to keep in view
The 2022 certificate applies to the tested aircraft. It should not be read as EASA-wide production approval, unrestricted road-and-air use or proof of customer deliveries.
Make the transformation a structural problem
AirCar’s wings retract and its tail changes position to produce a more compact road configuration. In flight, those surfaces must provide the geometry and stability expected of an aircraft. The same object therefore has to satisfy two very different sets of physical requirements.
The 2021 inter-city demonstration showed the transition as a real sequence rather than an animation. Klein Vision subsequently reported more than 70 hours of flight testing and over 200 take-offs and landings before the prototype’s 2022 airworthiness milestone.
Separate a demonstrated machine from a transport promise
The company presented a further production prototype in 2025. That is a development stage, not evidence of a mass-market service or a general European type certificate.
The engineering is worth studying without assuming that flying cars solve congestion. Airfields, pilot qualifications, weather, maintenance and certification remain part of the journey. The achievement here is a physical transformation that has been tested in flight.

A 35-minute flight between two airports
Klein Vision documents its prototype flying from Nitra to Bratislava on 28 June 2021. The journey demonstrated flight between airports, followed by conversion for road travel.
What this tells us. A prototype flight and an individual airworthiness certificate do not establish mass production, routine passenger service or general type certification.

Start with the flight that fits.
Both demonstrate that aircraft innovation includes certification and operating constraints. Compare a transforming prototype with a certified training aircraft.
A bicycle. A boat. A bed.
Both combine transport modes within one object. The transition between modes creates its own engineering and practical requirements.
