JEKTA, the Switzerland-based manufacturer specialising in zero-emission amphibious aircraft, has unveiled new photographs of its 1:9 scale model of the Passenger Hydro Aircraft – Zero Emissions 100 (PHA-ZE 100). The detailed model is currently supporting an extensive flight- and water-testing campaign in Italy, where the company continues to validate and refine the next-generation design.

Closely aligned with the final configuration, the scale model incorporates key elements of the definitive PHA-ZE 100, including a distributed electric propulsion system powered by eight electric motors, an advanced aerodynamic profile, and expansive cockpit and cabin windows. Data gathered from the model’s operation in both air and water is being used to validate computer simulations and inform design adjustments ahead of the aircraft’s planned entry into service.

Testing is being conducted in Italy under the guidance of JEKTA’s Head of Design, Max Pinucci. The nation’s long history of seaplane development has provided inspiration for the team, reinforcing the aircraft’s place within a legacy of pioneering waterborne aviation.

JEKTA CEO and co-founder George Alafinov noted that the large scale of the model offers meaningful insights:
“The 1:9 scale model is large enough to provide data representative of the full-size aircraft and is allowing us to efficiently expand the test envelope while verifying data already collected in our computer modelling. We will continue to refine the aircraft configuration based on findings from the model testing and feed back into our digital models, ensuring the aircraft’s maturity as we work towards introducing it to the global air transport network in 2030.”

Since its launch in 2022, the PHA-ZE 100 has attracted more than USD 1.35 billion in forward commitments. With production scheduled to begin in 2030/2031, the all-electric, all-composite amphibious flying boat is intended to meet a diverse range of operational needs. The design supports regional passenger transport, corporate shuttles, medevac missions, VVIP operations, and cargo services, aided by flexible cabin layouts and low operating costs.

The aircraft will use hydrogen fuel cell technologies and be certified to Part 23 standards. Designed for robust performance across varied environments, the PHA-ZE 100 will operate from coastal waters with waves up to 1.2 metres, as well as lakes, rivers, and both paved and unpaved runways. A retractable wheeled undercarriage will enable full amphibious capability.
