A new VX4 air cab from Vertical Aerospace has completed Phase 1 of its piloted test program at the Vertical Flight Test Center. During this phase, the vehicle conducted more than 20 tethered piloted flights, in addition to ground tests, covering a total of 70 individual points.
These tests were instrumental in simulating multiple flight situations, including unanticipated operational scenarios, which contributes to the validation of the safety of the aircraft. aircraft. Vertical Aerospace demonstrated the VX4’s ability to handle failures, thus consolidating the robustness of its design.

Successful simulation of air cab failures
One of the highlights was the simulation of an Electric Propulsion Unit (EPU) failure during a tethered flight, ensuring that the prototype can respond correctly in critical conditions. Throughout the testing, engineers collected data from 35,000 flight and system parameters, confirming that the VX4 operates safely under a variety of conditions.
Likewise, the company conducted low-speed and high-speed cab tests, including deliberate failure of EPUs at high cab speeds, to ensure vehicle safety and control. Vertical is collaborating with the UK Civil Aviation Authority (CAA) for approval of the next phase of testing. phase of testingwhich will involve thrust flights.
The next step for Vertical Aerospace is the construction of an identical full-scale prototype, which will accelerate its testing program and demonstrate the operational capability of the VX4. Lessons learned from both tests will be applied to the final certified model.
Features of the VX4
The latest model, the result of collaboration with global companies such as GKN Aerospace, Honeywell and Molicel, features 20% more power compared to its predecessor, allowing it to reach speeds of up to 150 mph and a range of 100 miles, all with zero operating operations.
This air cab has a capacity for four passengers and has been designed to take off and land vertically, similar to a helicopter, but with the efficiency and silence of an electric plane. electric aircraft. The prototype integrates next-generation propellers and patented battery technology, capable of delivering 1.4 MW of peak power, developed at the Vertical Energy Centre in the UK.
Its compact and lightweight design, together with its advanced electric propulsion electric propulsion systemspropulsion systems, provide a quieter and more efficient flight experience. In addition, it has multiple redundant systems and automated controls to ensure safety in various flight conditions, highlighting its ability to handle critical situations such as simulated propulsion system failures.
Phase 1 highlights
- Tethered flight with pilot: Stationary tethered flights were performed to evaluate stability and safety, including simulation of EPU failures and aircraft response.
- Ground vibration test: With the collaboration of ATA Engineering, eight shakers and 350 accelerometers were installed to simulate different flight conditions, gathering crucial data for the design.
- Power train test: Evaluated power generation and delivery to the propellers, including a high voltage ripple test to ensure power supply stability.
- Dynamic and propeller tests: They verified the correct installation and operation of the systems, and measured the weight distribution of the blades to minimize vibrations.
- Cab tests: They allowed testing maneuverability at low and high speed, including brake and control tests with differential thrust.
Vertical Aerospace CEO Stuart Simpson highlighted the speed of progress, stating that they went from ground testing to piloted flights within a week. “We are proving that our design and technology are market leading,” Simpson commented. With 1,500 orders valued at $6 billion, the company is moving into the next phase to bring the VX4 into full-scale production.
