Vertical Aerospace (NYSE:EVTL) shares gained 1% in premarket trading after the company confirmed it had successfully completed phase 3 wingborne testing with its full-scale VX4 prototype, achieving stable and efficient flight performance.
The aircraft exceeded expectations during piloted flights covering 250 miles (400 km), generating over 22 billion data points. Vertical Aerospace is now moving into the final flight test stage—transition—scheduled for completion by the end of 2025.
This milestone is a key step toward the company’s goal of type certification in 2028. The phase 3 tests validated the VX4’s ability to achieve stable, efficient flight while relying on its wings for lift.
“The testing progress reflects continued regulator confidence in our development program,” the company said. Vertical Aerospace plans to provide further details about its test results and certification roadmap at its upcoming Capital Markets Day on September 17 in New York.
The VX4 serves as Vertical Aerospace’s flagship electric vertical takeoff and landing (eVTOL) aircraft, designed for urban air mobility. The company is targeting the emerging electric air taxi market, aiming to transform short-distance urban transportation.
