Switzerland & USA – H55 the Swiss electric aviation pioneer born from the Solar Impulse program, reported that its Bristell B23 Energic completed more than 50 demonstration flights with potential buyers at Palo Alto Airport (KPAO) and turned multiple on-site visits into purchase agreements. These new commitments have already filled the production planning for the first two years.
The Palo Alto campaign demonstrated two key advantages. First, the B23 Energic’s negligible energy cost and minimal maintenance profile substantially reduce operating expenses for training operators. Second, pilots consistently praised the aircraft’s smooth, vibration-free flight characteristics, underscoring the superior training experience delivered by electric propulsion. This immediate, first-hand validation converted casual ramp-side curiosity into signed orders, signalling that the U.S. market is ready for electric flight training today.
André Borschberg, Executive Chairman & Co-Founder, H55 commenting on the company’s experience in Palo Alto, “Flying Solar Impulse around the world proved that electric propulsion could conquer the skies; the B23 Energic proves it can conquer the business case. We are now at an important turning point in our growth as we start to generate product revenue on top of engineering revenue. Our battery pack qualifications will be completed this summer, full aircraft certification will follow shortly thereafter, and our order book is filling fast. Our Across America program is showing a clear message: electric aviation has moved from the future to the present tense.”
The B23 Energic: Transition from Visionary Concept to Everyday Commercial Reality
For flight-training operators, the B23 Energic replaces fuel burn, engine overhauls and noise complaints with overnight charging, minimal scheduled maintenance and near-silent circuits. Its 80-minute endurance at the end of the life of the battery (for the 1st aircraft deliveries in the USA), combined with negligible energy draw during taxi, run-up and pattern work—delivers block times comparable to legacy piston trainers while enabling additional daily sorties at noise-sensitive airports.
“The Palo Alto stopover confirmed—yet again—that flight schools and aero-clubs are no longer just curious about electric training; they are ready to buy,” states Gregory Blatt, H55 Co-Founder & Mission Director. “In just a few days we logged more than 50 sorties, with 8 flights per day. We welcomed dozens of walk-up visitors and converted that interest into firm purchase agreements on the spot. Operators told us the math is undeniable: a five-dollar energy bill per flight hour, virtually no engine maintenance, and the freedom to fly extra evening circuits without disturbing the neighborhood.”
De-risked Growth Opportunity and Validating H55’s Roadmap
With its first- and second-year production slots sold out and all CAPEX already funded, H55 is primed for rapid, cost-efficient expansion. Imminent certification, a broadening customer roster, and validation from industry leaders such as Pratt & Whitney and CAE underscore the company’s readiness to deliver decarbonized aviation propulsion and battery systems at scale.
The tour stops also reinforced H55’s broader technology roadmap. Building on lessons learned from the Solar Impulse circumnavigation, the B23 Energic showcases a battery technology and architecture that is identical to the platform selected for RTX’s 1 megawatt Dash 8 Hybrid-Electric Flight Demonstrator. The shared system proves scalability from CS-23 two-seat trainers to future CS-25 regional airliners, setting the stage for commercial electric aircraft of up to 80 seats.
Next Stops on the Across America Tour
The B23 Energic continues its eight-state journey with public showcases in Centennial, Colorado (July 5-12), Oshkosh, Wisconsin (EAA AirVenture, July 21-27), and East Hampton, New York (August 6-10). These stops will engage aviation enthusiasts, industry leaders, and communities, furthering H55’s mission to scale sustainable aviation.

USA – The Cessna 172 Skyhawk marks 70 years of flight this month, as it continues to lead the industry as the most popular aircraft in the world. The iconic high-wing Cessna 172, now known as the Skyhawk, first took flight in June 1955. Through the intervening decades, more than 45,000 172s have been delivered to customers across the globe.
Calgary, Canada – Avsoft International has entered into a new partnership with Pacific Sky Aviation, a Canadian flight training provider based in British Columbia. Under the agreement, Pacific Sky Aviation will integrate Avsoft’s Dash 8 Q400 aircraft systems course into its training curriculum.
The Dash 8 Q400 course, designed with flexible modules and comprehensive technical detail, enables Pacific Sky Aviation to deliver effective and efficient training to its pilots. The course supports both initial and recurrent training needs, and is accessible through Avsoft’s proprietary Learning Management System (avLMS) or can be integrated with a third-party LMS.
