AVIATION GUIDANCE FROM THE UK CIVIL AVIATION AUTHORITY
“
...the aviation community must engage positively in the process of developing solutions to potential conflicts of interest between wind energy and aviation operations.... Those involved in addressing wind energy and aviation issues must do so in a positive, co-operative and informed manner.” (from the CAA’s published guidance)
In the medium to long term, within the context of the Government’s intention to release surplus public sector spectrum, the CAA is assessing the feasibility of emerging technologies to meet the safety and operational requirements of a future surveillance environment. A key element of this work is to identify the feasibility of delivering a strategic solution to the impact
assistance to planning authorities when assessing whether aviation arguments are considered, supportable and reasonable, in order to facilitate a fair process.
We strongly encourage early engagement by all parties to enable understanding and assessment of the issues and mitigation techniques. Our ultimate aim is to promote a positive influence with regards to wind energy and aviation being able to co-exist rather than conflict.
AVIATION EFFECTS The development of sites for wind turbines have the potential to cause a variety of effects on aviation. These include (but are not limited to)…
• Physical obstructions • The generation of unwanted returns on Primary Surveillance Radar
• Adverse affects on the overall performance of navigation equipment turbulence.
SUMMARY DOCUMENT The CAA have published a summary of the issues that planners and developers should consider when assessing the impact of a proposed wind turbine development. This guidance is also designed to enable aerodrome operators and Air Navigation Service Providers to provide expert interpretation of what the impact will be on their operations, and how it will affect the safety, efficiency and flexibility of their specific operations. The document discusses the various mitigation measures available, providing a descriptive overview and an analysis of the different techniques.
BALANCED APPROACH The CAA tries to promote a balanced approach to wind energy to enable the UK to meet Government renewable energy targets, whilst ensuring aviation issues, particularly safety concerns, are addressed.
RESPONSIBILITY The CAA is responsible for safety regulation of civil aviation in the UK. On that basis, they have an obligation to provide assistance to aviation stakeholders to help them understand and address wind energy-related issues. However, it is acknowledged that other users such as planning authorities, wind energy developers and members of the general public may also need our advice.

of wind turbines on radar systems, thereby reducing the obstacles to wind turbine planning.
PROVIDING POLICY AND GUIDANCE Our purpose, then, is to provide policy and guidance on a range of issues associated with wind turbines and their effect on aviation that will need to be considered by all interested parties when assessing the viability of wind turbine developments. The CAA does not routinely object or support planning applications for wind turbines and would not seek to unfairly influence the planning process. In addition, we cannot provide an arbitration service. Rather, we are able to offer regulatory advice and guidance to all stakeholders and impartial
GUIDANCE UPDATES The CAA regularly update their advice to ensure it remains relevant and balanced and contains the latest information and most accessible explanations with regards to the effects and mitigation techniques. The aim is to ensure a positive approach to mitigation and the ability to overcome aviation issues. This includes new information on the next generation offshore wind developments - the scale of which is likely to increase in the coming years requiring additional considerations for stakeholders.
