AMSL Aero's Vertiia eVTOL aircraft has started untethered flight tests in New South Wales.

AMSL Aero has started untethered test flights with its Vertiia eVTOL aircraft as it works to complete type certification in 2027. After logging some 50 tethered flights since 2023, the Australian start-up this week reported that it removed tethers for the first time earlier this month.

The technology demonstrator now being used for test flights operates on battery power, but in 2025 AMSL aims to start flying with a hydrogen-electric propulsion system intended for production aircraft. Flight testing is being conducted with the approval of Australia’s Civil Aviation Safety Authority (CASA) at a site in the Central West region of New South Wales.
