Farnborough – October 31, 2026 -- Brazil's National Civil Aviation Agency (ANAC) has published proposed noise certification criteria for Eve Air Mobility's Eve 100 eVTOL aircraft, with public consultation open until August 8. Eve (NYSE: EVEX) calls the publication a key milestone toward type certification and toward an environmental certification framework for eVTOLs.
ANAC adapts existing aviation noise rules to the Eve 100
The criteria follow extensive engagement between Eve and ANAC. They draw on existing aviation noise regulations and adapt them to the Eve 100 and its planned operations. They are meant to evaluate the aircraft's acoustic characteristics across all phases of flight, giving regulators an environmental profile before commercial operations begin.
Eve CEO Johann Bordais said the framework is tailored to an emerging technology aircraft and supports international regulatory alignment. Isabel Lima, Eve's Head of Noise and Vibration, called noise an important factor in public acceptance of urban air mobility.
Eve backs its noise case with a 100-participant perception study
Eve says the Eve 100's lift-plus-cruise architecture was designed to be quieter than conventional helicopters. The company's Visual & Sound Perception Study, run with the Royal Netherlands Aerospace Centre (NLR), used virtual reality and sound simulations. It engaged more than 100 participants across New York, Orlando and San Francisco to gauge how communities perceive eVTOL operations in urban and suburban settings.
Acoustic modeling assessments and engineering prototype flight testing continue alongside the study, as Eve works to optimize the Eve 100's noise characteristics.
ANAC will review stakeholder input before finalizing requirements
After the consultation closes, ANAC will review stakeholder contributions and continue work toward finalizing the applicable certification requirements. Eve describes ANAC as its primary certification authority and is pursuing international validation activities to support the aircraft's future global deployment. The company also takes part in global regulatory discussions on future noise standards for advanced air mobility.
