Jekta’s PHA-ZE 100: A New Chapter in Electric Amphibious Aviation
In a significant step toward sustainable regional aviation, Jekta Aerospace has initiated flight trials of a scaled model of its PHA-ZE 100, an electric amphibious aircraft. These trials mark a critical milestone in the aircraft’s development and offer a glimpse into the future of environmentally friendly, versatile air transport. Amphibious aircraft have long served niche roles in remote access, maritime operations, and tourism. With the PHA-ZE 100, Jekta aims to modernize this legacy with cutting-edge electric propulsion and digital design tools.
As climate targets tighten and demand grows for cleaner, quieter, and more adaptable aircraft, the aviation industry is undergoing a major transformation. The PHA-ZE 100 fits squarely within this evolution, combining amphibious design with electric or hybrid-electric propulsion. The current flight trials using a 1:9 scale model are not just symbolic, they are a technical necessity to validate advanced simulations and ensure the aircraft’s real-world performance aligns with its digital twin.
Flight Trials and Digital Validation
Scaled Model Testing: Bridging Theory and Practice
Jekta Aerospace’s flight trials involve a 1:9 scaled model of the PHA-ZE 100, a strategy increasingly adopted across the aerospace sector. This model is being used to validate computational fluid dynamics (CFD) simulations and aerodynamic predictions made during earlier design phases. By testing the scaled version in real-world conditions, engineers can confirm or adjust their digital assumptions, reducing the risk of costly errors when scaling up to a full-size prototype.
The use of scaled models allows for a more agile development process. It provides valuable data on lift, drag, stability, and hydrodynamic behavior, critical factors for an amphibious aircraft that must perform efficiently in both air and water. These trials also help assess how the aircraft handles takeoff and landing transitions on different surfaces, a key performance metric for amphibious operations.
Charles Alcock, Managing Editor at Aviation International News, emphasizes the role of these tests: “Using a 1:9 scale model allows Jekta to test aerodynamic and hydrodynamic performance in real conditions, bridging the gap between computer models and full-scale aircraft behavior.” This approach is not just about validation, it’s about learning and refining early, before committing to full-scale production.

Digital Twins and Simulation Tools
The PHA-ZE 100 development process is heavily reliant on digital twins, virtual models that mirror the physical aircraft in real-time. These tools allow engineers to simulate a wide range of flight conditions, system responses, and environmental variables without the need for physical prototypes at every stage. It’s a method that increases safety, reduces cost, and accelerates development timelines.
By validating the digital twin against real-world data from the scaled model, Jekta ensures that its simulations are accurate and reliable. This process is especially important for electric aircraft, where battery performance, weight distribution, and thermal management are critical factors that must be precisely modeled and tested.
Digital validation also supports regulatory certification processes, which increasingly require comprehensive simulation-based evidence alongside traditional flight testing. For a novel aircraft like the PHA-ZE 100, this rigorous approach is essential to gain approval from aviation authorities.
Environmental and Operational Implications
The PHA-ZE 100 is being developed with electric or hybrid-electric propulsion in mind, aligning with global efforts to decarbonize aviation. Electric propulsion offers multiple benefits: reduced emissions, lower noise levels, and potentially lower operating costs due to fewer moving parts and simpler maintenance requirements.
These features make electric amphibious aircraft particularly attractive for operations in environmentally sensitive areas, such as national parks, island chains, and coastal communities. The quiet operation reduces noise pollution, while the absence of fuel spills enhances environmental safety during water landings and takeoffs.
Although Jekta has not disclosed specific cost figures, electric aircraft typically require significant upfront investment. However, long-term savings in fuel and maintenance, combined with growing regulatory and consumer pressure for sustainable transport, may offer a compelling business case for operators.
Industry Context and Broader Trends
Electrification in Aviation

Sora Aviation Completes S-1 Subscale VTOL Flight Testing
Sora Aviation completed subscale VTOL flight testing for its 30-seat S-1 eVTOL in Wales, targeting a full-scale prototype flight in 2028.
This article summarizes reporting by eVTOL Insights by Jason Pritchard.
British electric aviation developer Sora Aviation announced on June 25, 2026, the successful completion of a subscale vertical take-off and landing (VTOL) flight testing program for its proposed 30-seat S-1 aircraft at the Snowdonia Aerospace Centre in Wales. The campaign generated critical flight data that will directly inform the design of the full-scale prototype, which is targeted to fly in 2028.
According to reporting by eVTOL Insights, the subscale demonstrator completed dozens of flights over several months. The testing allowed engineers to evaluate the aircraft’s stability, control, and flight characteristics during repeated VTOL operations in a lower-risk environment. This milestone is intended to de-risk the technology before the company begins construction on the full-scale prototype.
Subscale testing and validation strategy
Sora Aviation Chief Executive Officer Furqan Afzal emphasized the company’s comprehensive approach to development. As reported by eVTOL Insights, Afzal stated the manufacturers invested in a rigorous validation strategy that combines simulation, laboratory testing, wind tunnel campaigns, and representative flight demonstrators.
“This milestone demonstrates the maturity of our development approach and the strength of the engineering foundations underpinning the S-1 programme,” Afzal said.
The data gathered at the Welsh testing facility will be used to refine the S-1’s engineering foundations. Aerospace Global News reported that Afzal views the flight data as validation of the aircraft’s potential, noting that the results reinforce the company’s confidence that the S-1 can deliver the required performance, safety, and economics for advanced air mobility operations.
S-1 program timeline and commercial milestones
The S-1 is designed as a 30-seat electric vertical take-off and landing (eVTOL) aircraft. Aerospace Global News reported that the full-scale prototype is projected to make its first flight in 2028. The flight testing milestone follows earlier component validation efforts. On January 20, 2026, Sora Aviation began testing the S-1’s energy storage system at a bespoke battery performance laboratory at the IAAPS centre, in collaboration with the University of Bath.
The company has also secured early commercial interest and explored alternative applications for the airframe. In March 2025, South Korean charter operator Moviation signed a pre-order agreement for 20 S-1 aircraft, intending to deploy them on high-demand airport shuttle routes, according to Aviation International News. Aviation Week reported in May 2026 that Sora Aviation was studying a conceptual hybrid-electric variant of the 30-seat aircraft for potential use as a United Kingdom Navy helicopter.
AirPro News analysis
We view the completion of subscale flight testing as a standard but essential risk-reduction step for any novel eVTOL configuration. By validating aerodynamic models and flight control laws on a subscale airframe, Sora Aviation can identify and correct stability issues before committing to the high costs of full-scale prototype manufacturing. The 30-seat capacity of the S-1 places it in a larger size category than many competing eVTOL designs, which typically target four to six passengers. This larger payload requirement will place significant demands on the aircraft’s battery and thermal management systems, making the concurrent testing at the IAAPS centre critical to the program’s viability.
