Hello Nuno,

In the context of air traffic control and runway safety, runway incursions are a serious concern. There are several regulatory and best practice guidelines that address the issue of runway incursions and the role of runway wind indications. While I cannot point to a specific regulation that mentions “blockage of runway winds indication,” here are some relevant points and references you might consider:

ICAO (International Civil Aviation Organization) Standards and Recommended Practices (SARPs):
• ICAO Annex 14 (Aerodromes) addresses the design and operation of aerodromes, including runway safety and the importance of providing accurate wind information.
• ICAO Doc 9870 (Manual on the Prevention of Runway Incursions) provides guidelines and best practices for preventing runway incursions. It emphasises the importance of clear communication and accurate information, including wind data, to pilots and ground personnel.

FAA (Federal Aviation Administration) Regulations and Guidance:
• FAA Advisory Circular (AC) 150/5300-13A (Airport Design) outlines standards for airport design, including runway markings and signs that help prevent runway incursions.
• FAA Order JO 7110.65 (Air Traffic Control) contains procedures for air traffic controllers, including the provision of wind information to pilots. Accurate wind data is critical for safe runway operations.

EASA (European Union Aviation Safety Agency) Regulations:
• EASA CS-ADR-DSN (Certification Specifications and Acceptable Means of Compliance for Aerodromes Design) provides guidelines for the design and operation of aerodromes within Europe, including runway safety measures.

Best Practices and Mitigation Strategies:
• Ensuring that all wind sensors and indicators are properly maintained and free from obstructions to provide accurate wind information.
• Implementing advanced surface movement guidance and control systems (A-SMGCS) to enhance situational awareness and prevent runway incursions.
• Regular training and awareness programs for air traffic controllers and pilots on the importance of accurate wind information and communication.

While there may not be a specific regulation explicitly mentioning the “blockage of runway winds indication,” these references emphasise the importance of accurate wind data and clear communication to mitigate runway incursions. It would be beneficial to review these documents in detail to ensure compliance with the relevant regulations and best practices.

If you need more specific information or the latest updates, you might consider contacting your regulatory authority or consulting the latest versions of these documents.
