Archer Aviation Launches No Roads eVTOL Tour Ahead of LA28
Archer Aviation begins its No Roads flight tour in Northern California, expanding to LA, Texas, and Florida ahead of the 2028 Olympics.

Archer Aviation Inc. announced the launch of its “No Roads” flight tour on September 3, 2026, initiating a multi-state demonstration of its Midnight electric vertical takeoff and landing (eVTOL) aircraft. The tour aims to introduce the public to electric air taxi operations ahead of the 2028 Los Angeles Olympic Games and fulfills the company’s role in a federal integration initiative.
In a press release issued on September 3, 2026, the manufacturer detailed plans to conduct city-to-city flights starting in Northern California, closely coordinated with the Federal Aviation Administration (FAA). The campaign follows a highly active testing period in August 2026, during which Archer completed more than 70 test flights, including a piloted roundtrip journey between Salinas Municipal Airport (SNS) and Monterey Regional Airport (MRY).
Expanding the flight test footprint
The initial phase of the tour will focus on the San Francisco Bay Area and surrounding regions. Planned flight locations include Monterey, Hollister, San Martin, San Jose, Oakland, and San Francisco. Following the Northern California demonstrations, Archer intends to expand the tour to the Los Angeles basin, Texas, and Florida.
The flights are designed to showcase the operational capabilities of the piloted, four-passenger Midnight aircraft. Archer stated the tour will highlight the aircraft’s low noise profile, zero operating emissions, and ability to complete routes in 10 to 20 minutes that typically require an hour or more by car.
“I’ve talked a lot about the ‘Waymo Moment for air taxis,’ the chance for us to get communities more comfortable with this tech,” said Adam Goldstein, Founder and CEO of Archer. “This is the beginning of that story and our biggest step yet toward making air taxis an everyday reality in cities across America. The ‘No Roads’ Tour is how we bring that narrative to life while also preparing for what’s next: flights in multiple states under the White House’s pilot program, and the first Midnight flights in Los Angeles ahead of LA28.”
Federal integration and infrastructure development
The multi-state tour aligns with Archer’s participation in the White House’s eVTOL Integration Pilot Program (eIPP). In March 2026, the United States Department of Transportation (DOT) and the FAA selected Archer’s partners in New York, Florida, and Texas to join the initiative. The eIPP is designed to establish an operational playbook for the safe and scalable deployment of electric air taxis within the national airspace system.
Alongside the flight demonstrations, Archer plans to unveil new charging infrastructure across multiple states. This rollout is part of the America’s Consortium for Electric Skyways (ACES) program, a collaborative effort involving Archer, BETA Technologies, and Macquarie Capital.
The Los Angeles segment of the tour will serve as direct preparation for the 2028 Olympic Games. Archer is designated as the Official Air Taxi Provider for the LA28 Games, where it plans to operate a commercial network transporting attendees across the congested Southern California region.
AirPro News analysis
We view the “No Roads” tour as a critical transition phase for Archer Aviation, shifting the focus from pure technical certification to public acceptance and operational integration. While completing 70 test flights in a single month demonstrates growing maturity in the Midnight platform, flying visible, city-to-city routes in congested airspace like the San Francisco Bay Area and Los Angeles basin presents a different set of challenges.
Coordinating these flights with the FAA will likely serve as a real-world stress test for air traffic control integration. The concurrent rollout of ACES charging infrastructure indicates that Archer and its partners recognize that aircraft certification alone is insufficient without the ground network required to sustain high-frequency commercial operations by 2028.

Horizon Aircraft Begins FIKI Ice Protection Testing for Cavorite X7
Horizon Aircraft starts wind tunnel ice protection testing for the Cavorite X7 eVTOL, backed by a $10.5M INSAT-funded project.

New Horizon Aircraft Ltd. has commenced wind tunnel testing of ice protection technologies for its Cavorite X7 hybrid-electric vertical takeoff and landing (eVTOL) aircraft, marking a critical step toward achieving Flight Into Known Icing (FIKI) certification. The testing, which began in July 2026 in Toronto, Ontario, aims to validate systems that will allow the aircraft to operate reliably in harsh winter conditions.
In a press release issued on September 1, 2026, Horizon Aircraft announced the testing milestone, which is being conducted in partnership with the Flight Test Centre of Excellence (3C) and the University of Toronto (UofT). The research is supported by a $10.5 million project funded by the Initiative for Aerospace Innovation and Training (INSAT). Securing FIKI certification would enable the Cavorite X7 to service remote northern communities year-round, overcoming the weather-related grounding limitations frequently experienced by traditional helicopters.
Advancing all-weather eVTOL capabilities
The initial phase of wind tunnel testing focuses on small coupon samples featuring ice protection technologies developed by the University of Toronto. These systems are designed specifically to handle the aerodynamic and environmental challenges of hybrid-electric vertical flight in freezing conditions.
Horizon Aircraft Co-Founder and Chief Executive Officer Brandon Robinson stated that the Cavorite X7 was designed from its inception to handle Canadian winters to benefit both remote communities and aircraft operators.
“3C’s Certification expertise and UofT’s technology are supporting our progress toward bringing a certified all-weather X7 to market. Communities serviced by X7 aircraft will have greater access to the critical services they need, and X7 operators will experience higher aircraft utilization and profit margins,” Robinson said.
Certification pathway and recent program milestones
Achieving FIKI certification is a complex regulatory hurdle that few advanced air mobility (AAM) developers have actively targeted in their initial design phases. To navigate the Transport Canada (TC) certification process, Horizon Aircraft is leveraging the mentorship of 3C.
Dr. John Maris, Founder of 3C, emphasized the necessity of accounting for harsh climates to unlock the true potential of global air vehicle operations. He noted that the combination of the aircraft’s design, 3C’s regulatory guidance, and the university’s technology positions Horizon Aircraft to provide a regional air mobility solution that traditional rotorcraft struggle to match.
The start of ice protection testing follows a series of supply chain and commercial milestones for the Cavorite X7 program. On July 9, 2026, Horizon Aircraft selected BETA Technologies to supply the fly-by-wire advanced flight control computers and customized software for the aircraft. Shortly after, on July 21, 2026, the manufacturer secured a Letter of Intent (LOI) with Australian operator V-Star Powered Lift Aviation for the purchase of up to 100 Cavorite X7 aircraft, an agreement valued at approximately $600 million.
AirPro News analysis
We view Horizon Aircraft’s explicit pursuit of FIKI certification as a key differentiator in the crowded eVTOL market. Most developers in the advanced air mobility sector are optimizing their initial designs for temperate, urban environments to simplify their path to type certification. By tackling icing conditions early in the development cycle, Horizon Aircraft is taking on significant technical and regulatory risk upfront. However, if successful, this strategy could secure a distinct competitive advantage in utility, medical evacuation, and regional transport markets where dispatch reliability in adverse weather is a strict operational requirement.
