The initial public presentation of VoltAero's Cassio 1 hybrid-electric demonstrator is planned at next month's France Air Expo in Lyon – with this flight-proven aircraft presented on static display at the three-day European general aviation event.

"France Air Expo is a natural choice for Cassio 1's initial air show appearance," said Jean Botti, VoltAero's CEO and Chief Technology Officer. "We've already logged more than 40 hours during 70-plus flights with the demonstrator as we validate our hybrid-electric technology, and the time is right to enable the general aviation sector to see it first-hand at a major gathering."

In addition to the presence of Cassio 1 – which will be flown to Lyon from VoltAero's headquarters at Royan-Medis Airport in south-western France – the company also will be unveiling the first scale model of its series-production Cassio 2 version.

"We are particularly proud to welcome Cassio 1 as a world premiere at the 2021 edition of France Air Expo," stated Didier Mary, the show's organiser. "As a French company, VoltAero is once again demonstrating that our industry is ready to meet the challenges for aviation of the future."
