CAP 764 Wind Turbine Policy Consultation

Closes 23 May 2024

Opened 28 Mar 2024


This consultation concerns the proposed revision to CAP 764: CAA Policy and Guidelines on Wind Turbines.

Draft CAP 764 edition 7’s most significant change is to reorder text and introduce new chapters on specific topics.

The main drivers for change are incorporating a general permission for aviation obstacle lighting requirements for onshore and offshore wind turbines, previously published separately on the CAA web site, incorporation of international standards for wind turbines specified the International Electrotechnical Commission Technical Standard 61400-29:2023 as well as general editorial updates.

Why your views matter

CAP 764 is published to assist aviation stakeholders to help understand and address wind energy related issues and potential impact of proposed wind turbine developments. The document is also used by planning authorities, wind energy developers and members of the public.

It provides an overview of CAA policy and guidance to assist with understanding of some of the key issues to maintain aviation safety and efficiency while enabling renewable wind energy to grow.  We would be grateful particularly for feedback on points of accuracy, clarity and any omissions.

What Happens Next

Subject to views and comments provided in this consultation, we are planning to publish edition 7 of CAP 764: CAA Policy and Guidelines on Wind Turbines in June 2024.
