Canadian aerospace company Horizon Aircraft is continuing to advance the all-weather certification pathway for its hybrid-electric Vertical Takeoff and Landing (VTOL) aircraft, the Cavorite X7. In partnership with Flight Centre of Excellence (3C) and the University of Toronto (UofT), the company has begun testing ice-protection technologies, with the goal of eventually obtaining Flight Into Known Icing (FIKI) certification and enabling year-round regional air mobility.
Wind Tunnel Testing Begins to Assess Ice Protection Technology
Horizon Aircraft said its previously announced $10.5 million INSAT-funded all-weather vertical propulsion eVTOL project with 3C and UofT is progressing steadily. Wind tunnel testing began in July 2026 using small test samples incorporating UofT’s ice-protection technologies, marking the first step in assessing whether the technologies can be applied to the Cavorite X7 as part of its certification efforts.
Dr. John Maris, founder of 3C, said that realizing the full potential of air vehicle operations worldwide requires addressing harsh climate conditions. He believes that by combining the Cavorite X7’s design with 3C’s certification expertise and UofT’s ice-protection technology, Horizon Aircraft could achieve FIKI certification and provide a reliable year-round regional air mobility solution in environments where helicopters can face operational limitations.
Designed for Harsh Winters and Remote Community Operations
Horizon Aircraft noted that many northern and remote communities in Canada and around the world continue to rely on helicopters to deliver critical goods and services, but cold temperatures, snow and poor weather frequently ground these aircraft. Unlike conventional helicopters and open-rotor eVTOL aircraft, the Cavorite X7 was designed from the outset to operate safely in winter conditions, giving the company a potential advantage in pursuing all-weather certification.
Horizon Aircraft Co-Founder and CEO Brandon Robinson said the Cavorite X7 was designed from the beginning with Canadian winters in mind, with the aim of serving both remote communities and aircraft operators. With certification expertise from 3C and ice-protection technology from UofT supporting the program, the company is progressing toward bringing a certified all-weather X7 to market. If successfully deployed, the aircraft could improve remote communities’ access to critical services while increasing aircraft utilization and potentially improving operator profit margins.
