ANAC Publishes Proposed Noise Certification Criteria for Eve 100
Rhea-AI Summary
Eve Air Mobility (NYSE: EVEX) announced that Brazil's National Civil Aviation Agency (ANAC) has published the Proposed Noise Certification Criteria for the Eve 100 eVTOL, now open for public consultation until August 8. This publication is described as a key milestone in Eve 100’s certification and a major step toward establishing an environmental certification framework for eVTOLs.
The criteria result from extensive engagement between Eve and ANAC and adapt existing aviation noise regulations to Eve 100’s specific operational and acoustic characteristics. They aim to evaluate noise across all flight phases before commercial operations. Eve highlights ongoing prototype flight testing, acoustic modeling, and a Visual & Sound Perception Study with NLR to understand community perceptions and support noise optimization and future global deployment.
Positive
- ANAC publishes proposed noise criteria for Eve 100, consultation to August 8
- Key milestone toward Eve 100 environmental and type certification framework
- Criteria tailored to Eve 100’s specific operational and acoustic characteristics
- Ongoing prototype testing and acoustic modeling to optimize noise performance
- Community perception study with NLR engaged 100+ participants in three U.S. cities
Negative
- Noise certification criteria are still proposed and subject to consultation and revision
- Eve 100 commercial operations have not begun; environmental impact remains under evaluation
- Final certification requirements depend on ANAC review after August 8 consultation

FARNBOROUGH,
"ANAC's publication of the proposed noise certification criteria is an important milestone in the development and certification of Eve 100," said Johann Bordais, CEO at Eve. "We appreciate ANAC's leadership and collaborative approach in developing a framework tailored to this emerging technology aircraft. This initiative supports the safe and responsible introduction of eVTOL operations for urban mobility while promoting international regulatory alignment."
As the aviation industry introduces innovative technologies that differ from conventional aircraft, dedicated certification criteria are necessary to address the unique operational and acoustic characteristics of these vehicles. The proposed criteria are the result of extensive engagement between Eve and ANAC and draw on existing aviation noise regulations, adapting them to the specific characteristics of Eve 100 and its future operations.
The consultation also reflects broader international efforts led by aviation authorities and industry stakeholders to develop harmonized approaches to emerging technologies. Eve continues to actively participate in global regulatory discussions, helping support the development of future noise standards for advanced air mobility.
"Aircraft noise is a critical component of aviation environmental certification and an important factor in public acceptance of urban air mobility," said Isabel Lima, Head of Noise and Vibration at Eve. "Noise certification establishes measurement methodologies and compliance criteria, ensuring that new aircraft are introduced with appropriate environmental protection and consideration for surrounding communities."
As part of the certification process, the proposed criteria are intended to evaluate the acoustic characteristics of Eve 100 throughout phases of flight, supporting a comprehensive understanding of the aircraft's environmental footprint before commercial operations begin.
Noise reduction has been a key consideration throughout the development of Eve's eVTOL. Drawing on a lift-plus-cruise architecture, the aircraft has been designed to deliver a quieter experience than conventional helicopters. Eve's approach to community acceptance is also supported by insights from its Visual & Sound Perception Study, conducted in collaboration with the Royal Netherlands Aerospace Centre (NLR). Using virtual reality and sound simulations, the study engaged more than 100 participants across
Following completion of the consultation period, ANAC will review stakeholder contributions and continue work toward finalizing the applicable certification requirements. Eve continues to work closely with ANAC as the primary certification authority, while pursuing international validation activities that support the future global deployment of Eve 100.
