英国CAA发布eVTOL噪声管理方案

The UK Civil Aviation Authority has published a new report examining how noise from drones and electric vertical take-off and landing aircraft (known widely as eVTOL) could be assessed and managed, as innovation in the sector continues to develop.

When compared with conventional helicopters operating in similar roles, drones and eVTOL aircraft are expected to be quieter. As these technologies continue to develop, and new business models emerge, understanding how noise is experienced by communities will help support their safe and sustainable integration into UK airspace.

Commercial drone operations are expected to expand significantly over the coming decade, with potential applications ranging from infrastructure inspection and emergency response to logistics and the transport of medical supplies.

Across the UK, the development of commercial eVTOL operations is one of the fastest-evolving areas of aviation innovation. With early applications expected to include airport transfers, regional connectivity, and emergency services support, eVTOLs could soon be seen across the UK, helping to improve connectivity while supporting the transition to more sustainable forms of air transport.

However, as services move beyond trials and into routine use, effective noise management will become increasingly important, with industry forecasts pointing to substantial growth in the international civil drone and eVTOL market, as use extends into new locations and becomes more frequent.

While increased commercial drone activity could deliver important societal and economic benefits through improved connectivity, more efficient services and reduced reliance on noisier or more carbon-intensive forms of transport that are currently in use, its successful introduction will also depend on how impacts on communities are understood and managed.

The new Civil Aviation Publication: Managing Noise from Emerging Aviation Technology (CAP3304), finds that drones and eVTOL aircraft may create different patterns of noise exposure from conventional aviation as these technologies become more widely used.

Despite being quieter than conventional helicopters, both of these technologies may operate differently, including at lower altitudes, closer to homes and across areas not traditionally affected by aircraft noise. These factors, such as noise characteristics, frequency of operation and visibility, may influence community experience.

The report considers how established aviation noise-management principles could be adapted for these new operations. It identifies priorities including quieter aircraft design, proportionate noise assessment, appropriate route and operating procedures, transparent community engagement, accessible complaints arrangements and the systematic collection of operational and noise data.

The work also complements the UK Civil Aviation Authority’s wider Future of Flight programme, which is helping to enable the safe integration of drones and eVTOL aircraft into UK airspace, supporting innovation while maintaining high standards of safety, security, and environmental protection.

Ed Weston, Head of Environmental Research and Consultancy at the UK Civil Aviation Authority, said: “Taking the opportunity to improve our understanding and develop good practice while the sector is still emerging and expanding is vital. A clear and proportionate approach to noise can protect communities, give operators greater certainty and support the responsible scaling of these new technologies and services that can deliver genuine public and economic benefits.”

The report has been developed to support the Department for Transport’s work on a national noise policy for drones. It recommends that initial policy should provide a framework for trials, early deployments and emerging commercial services that is proportionate, consistent, and able to evolve as operational experience and evidence improve.
