New Irish Aviation Authority policy document on Land Use

On 25th March, the Irish Aviation Authority (IAA) published its policy document on Land Use Planning & Offshore Development (version 1.00) following public consultation which ended on 7th November 2014. (The 44 page document can be viewed here). 

In a statement the IAA say it is thankful for the submissions received, all of which have been reviewed and the draft policy amended where appropriate. It goes on to outline what the Policy Document does.

  • It describes the role of the IAA, airspace users, aerodrome operators, providers of aviation communications, navigation and surveillance (CNS) systems and providers of other air navigation services (e.g. air traffic control and flight information services) and planning authorities – hyperlinks to relevant published material are included in the document;
  • It provides information on what constitutes an obstacle to aircraft in flight and the legal requirements for notification to the IAA of the erection or construction of such an object including its marking and lighting;
  • It addresses all types of developments including a dedicated chapter on land based and offshore wind farms;
  • It provides information to aerodrome operators and technical facilities providers with regard to safeguarding their services and facilities against unacceptable developments;
  • It brings existing IAA policy on Consultation with Planning Authorities up to date taking account of the latest standards, regulations and guidance material from the International Civil Aviation Organisation, the European Organisation for the Safety of Air Navigation, the EU and other authoritative entities;
  • It describes the Aeronautical Surfaces Screening Evaluation Tool (ASSET), the part it plays and how it can assist developers, the construction industry, planning authorities, aviation and other stakeholders in the performance of their functions.

So what happens next?

Chapter 7 of the policy document describes the web-based Aeronautical Surfaces Screening Evaluation Tool (ASSET) which is now available for use free of charge to assess whether or not the erection or construction of an object, permanent or temporary is likely to constitute an obstacle to aircraft in flight or interfere with aviation communications, navigation or surveillance systems.

The IAA will use ASSET as its main database for the recording and subsequent publication of obstacles to air navigation in electronic format (e-TOD electronic terrain and obstacle data).

The IAA will continue to engage with aviation stakeholders on using ASSET as the principal means by which obstacle information is provided to it and via which acceptance, approval or comments, as the case may be, are communicated.

Non-aviation stakeholders such as developers, the construction industry and planning authorities are strongly encouraged to use ASSET to ascertain whether or not any proposed construction is likely to be an obstacle to aircraft in flight, or interfere with the aviation CNS systems and which in either case may require further evaluation.  ASSET will record your proposal, circulate to the relevant aviation focal point(s) and alert you via email to consult ASSET for updates regarding your proposal. The IAA is also offering to give a presentation on ASSET to members of an industry collective body, association or federation. To invite such a presentation Contact +353 61 366089 or email:
