London, 26 July 2024:
Vertical Aerospace (Vertical) [NYSE: EVTL], a global aerospace and technology company pioneeringzero-emissions aviation, has seen its latest VX4 prototype perform its first tethered piloted flight as it
begins the “wheels up” phase of testing.
This VX4 performed a piloted flight while loosely tethered to the ground, during which Vertical measured
over 20,000 flight and system parameters to verify thrust, handling qualities and system performance.
The tethered piloted flight took place after the UK Civil Aviation Authority (CAA) had issued Vertical witha Permit to Fly for its VX4 prototype, having rigorously evaluated the engineering, design, test data andaircraft, effectively conducting a “mini certification” programme of the aircraft.
Vertical must submit documentation to the CAA to move through each flight phase, including extensive,
detailed documentation covering every aspect from safety protocols and engineering specifications tooperational procedures.
Following initial tethered flights, and once it has received permission from the CAA to expand the flightenvelope, the VX4 will enter the next phase of testing which will start with further thrustborne flighttesting. This will see the VX4 take-off and land vertically and conduct low speed flight manoeuvres with lift
generated by the propellers.

Wingborne or conventional flight (CTOL) and the final critical test stage of piloted transition flight will
follow, only once the CAA’s rigorous approval for this final phase of testing has been granted.
In advance of today’s first tethered flight, this week, the VX4 has successfully completed extensive groundtesting, including powered propulsion testing of its advanced powertrain, which features proprietary
battery packs capable of delivering 1.4 MW of peak power and which has been designed and built at thestate-of-the-art Vertical Energy Centre.
Stuart Simpson, CEO of Vertical Aerospace, said:“The first tethered flight of our new VX4 prototype is the result of 14 months of hard work – taking thisadvanced aircraft all the way from design, through to development and now into the air. This moment is
testament to the skill and commitment of hundreds of talented colleagues in our business who have madeour VX4 aircraft the best eVTOL out there.
“Everyone at Vertical Aerospace remains laser focused on achieving piloted transition as we continue toprogress towards our ultimate goal of commercialisation and creating a new legacy for aviation.”
Notes to editors:
Piloted flight test programme explainer:
1. Tethered: the VX4 will perform stabilised hover while loosely tethered to the ground.
2. Thrustborne: the VX4 will take-off and land vertically and conduct low speed flight manoeuvres with lift
generated by the propellers.
3. Wingborne: the VX4 will take-off, fly and land like a conventional aircraft, with lift generated by the wing.
4. Transition: The VX4 will transition between thrustborne and wingborne flight, and vice versa.
