Aviation News – VX4 Prototype Achieves Stable Wingborne Flight in Latest Test Phase

Vertical Aerospace has successfully completed Phase 3 wingborne flight testing of its VX4 electric aircraft, marking a major milestone in the company’s path toward type certification in 2028. The tests, carried out in open airspace, demonstrated the aircraft’s ability to fly like a conventional airplane, generating lift from its wings.

The VX4 prototype exceeded expectations across piloted flight missions, covering 250 miles (400 km) and gathering more than 22 billion data points. Pilots Simon Davies and Paul Stone tested both manual and computer-assisted control modes, with results aligning closely to simulator models. The tests validate the VX4’s quiet, low-power wingborne mode—an essential feature for making electric aviation scalable and commercially viable.

The VX4 transitioned smoothly between control modes, highlighting the design’s stability and efficiency. With regulatory oversight from the UK Civil Aviation Authority and validation support from the European Union Aviation Safety Agency, Vertical secured approvals to conduct the tests under an extended Permit to Fly.

“This achievement underscores our commitment to delivering safe, practical, and efficient electric air travel,” said Simon Davies, Chief Test Pilot at Vertical Aerospace. “The VX4 has flown exactly as expected, and we are confident as we move into the final transition testing stage.”

Vertical is now advancing to its final testing stage—transition flight—expected to conclude by the end of 2025. The company will present further details at its Capital Markets Day in New York on September 17, as it works toward securing certification and scaling commercial electric air taxi operations.

The successful wingborne trials reflect both technical maturity and growing regulator confidence, positioning Vertical as a frontrunner in the race to commercialize electric aviation. With certification targeted for 2028, the VX4 could soon become a practical and sustainable alternative to short-haul flights and helicopter travel.
